Title: Motor vehicle heating and ventilating system
Inventor: PARDY RONALD PETER
IPC: B60H1/00
Filed: 1965-10-14
Abstract: 1,073,077. Heating and ventilating vehicles. FORD MOTOR CO. Ltd. Oct. 14, 1965, No. 43565/65. Heading F4V. A motor vehicle heating and ventilating unit comprises a fresh air inlet 15, a flap valve 21 for regulating the proportions of air flowing through a heater matrix 11 and a by-pass 24, a first outlet 18, a second outlet 19 and a distribution flap valve 25. The latter may be set to any of the following positions: a first position 31 in which it closes the outlet from the heater matrix so that by-pass air is supplied to both outlets; a second position 32 in which it co-operates with a fixed baffle 26 to direct air from the heater outlet into the by-pass 24, the mixed air being supplied to both outlets; a third position 33 in which it closes outlet 18 so that all the inlet air is supplied to outlet 19; and a fourth position 34 in which outlet 18 is in free communication with the heater outlet so that most of the air passing through the heater is supplied to outlet 18 and most of the by-pass air is supplied to outlet 19. The latter comprises two conduits, only one of which is shown, each communicating at its upper end with a fixed cylinder 36 having an aperture 39 in its wall. A rotatable cylinder 35 having an aperture 40 in its wall and inclined vanes 38 at its outlet end is mounted in cylinder 36. Rotation of cylinder 35 thus controls the direction in which the air is discharged into the vehicle and provides windscreen demisting when apertures 39, 40 are aligned to supply air to a nozzle 43 via an upwardly convergent passage defined by plates 41, 42.
Patent GB-931185-A (GB)
Title: Improvements in and relating to ceramic, refractory and like products
IPC: C04B33/32
Filed: 1959-12-24
Abstract: Carbonaceous shales, fuel-enriched clays and like materials are dried, heated until they ignite, e.g. at 450 DEG C., completely oxidised at an approximately constant temperature between 750 DEG and 950 DEG  C. and partially sintered at not less than 950 DEG C. with supply of external heat.  The treated material may be granular but, as described, a moulded or extruded paste of carbonaceous shales, with or without ordinary or refractory pulp or clays, is cut if appropriate, dried, and heated as rapidly as possible in a kiln the combustion products of the ignition stage of which may supply the necessary heat.  After ignition, the temperature of the treated material continues to rise rapidly to 850 DEG C. where further rise is prevented by cold air admission, hot gaseous products draw-off, or both, the treated material maintaining its porosity and burning increasingly slowly until oxidation is complete when the temperature may have fallen slightly to 800 DEG C., and following which the temperature is raised to 1040 DEG C., 1080 DEG C. or more to effect the partial sintering.

Title: Improvements in or relating to die closure apparatus for die casting, injection moulding and other pressure machines
IPC: B29C45/68
Filed: 1962-11-20
Abstract: 995,899. Injection moulding machines. BUHLER GEB. Nov. 20, 1962 [Nov. 21,1961], No. 43845/62. Heading B5A. [Also in Division B3] A pressure die-casting or injection moulding machine comprises a cross-head 6 having relatively movable parts 5, 8 which form between them a chamber 11 which is supplied with pressure fluid to produce the die-closing force, a pressure-fluid actuated linkage 18-20 for moving and supporting the movable die carrier 21, and movable wedges 12 between the cross-head parts 5, 8 for locking said parts against relative movement together. Closing of the die by the piston 16 moves the links 20 to the abutting positions shown in Fig. 2. Closure force is then exerted by pressure fluid supplied to the chamber 11, after which wedges 12 are moved inwardly by pistons 13 to lock the die halves.
Patent GB-1087630-A (GB)
Title: Molybdenum compounds containing sulphur
IPC: C10N40/04
Filed: 1966-09-30
Abstract: Lubricant compositions comprise a hydrocarbon lubricant having dispersed therein 1/2 % to 80% of a molybdenum (VI) dialkyldithio-carbamate or a hydrogen sulphide reaction product thereof (see Division C2).  The two alkyl groups in the molybdenum (VI) dialkyl-dithiocarbamate may be the same or different. Suitably the molybdenum thiocarbamate compounds are added in the form of finely divided particles, e.g. less than 20 microns, either as a suspension or dispersion in an organic carrier solvent or in the solid form.ALSO:Molybdenum (VI) dialkyldithiocarbamates and their reaction products with H2S (probably thiomolybdates) are prepared by (a) acidifying at a temperature of -5 DEG  C. to 50 DEG  C. with dilute nitric acid, an aqueous solution comprising a mixture of sodium dialkyldithiocarbamate and sodium molybdate, the molar ratio of sodium dialkyl dithiocarbamate to sodium molybdate being 1:1 to 5:1 and the molar ratio of dilute nitric acid to sodium molybdate being 1:1 to 6:1; (b) recovering the molybdenum dialkyldithiocarbamate product, and when desired or necessary; (c) oxidizing the molybdenum dialkyldithiocarbamate product to molybdenum (VI) dialkyldithiocarbamate.  Compounds in which the alkyl groups are n-propyl, amyl or 2-ethylhexyl and their reaction products with hydrogen sulphide are claimed per se.  Suitably the two alkyl groups in the sodium dialkyldithiocarbamate are preferably the same.  When each contains one to three carbon atoms, e.g. sodium di-n-propyldithiocarbamate, the desired product, molybdenum (VI) di-n-propyldithiocarbamate is recovered in step (b), but when each contains four or more carbon atoms, e.g. sodium diamyldithiocarbamate, sodium di-(2-ethylhexyl)dithiocarbamate or sodium di-n-butyldithio carbamate, the molybdenum dialkyldithiocarbamate product recovered in step (b), which contains some pentavalent molybdenum compounds, must be oxidized to molybdenum (VI) dialkyldithiocarbamate by means of t-butylperoxide, t-butylhydroperoxide or cumene hydroperoxide.  Treating molybdenum (VI) dialkyldithiocarbamate with hydrogen sulphide for a time sufficient to effect replacement of an oxygen atom with a sulphur atom, results in a reaction product which is probably a thiomolybdate.  The compounds of the invention are used as lubricant additives (see Division C5).

Title: A control device for two separately switchable motors
IPC: B66C13/54
Filed: 1961-12-07
Abstract: 999,004. Controllers. SIEMENS-SCHUCKERTWERKE A.G. Dec. 7, 1961 [Dec. 7, 1960], No. 43947/61. Heading H2B. A control device for two separately switchable motors, by means of which they can be started in the same direction or in opposite directions as required, comprises two control switches 10, 11 with actuating arms 8, 9, an operating arm 3 universally pivoted as one end, two linkage rods 4, 5 rigidily connected to said end of the arm 3 and two intermediate rods pivoted at one end to the free end of a linkage rod and at the other to a switch-actuating arm. As applied to the control of a pair of winch motors movement of the arm 3 in the S-H plane (Fig. 2) causes the motors to turn in opposite directions thus hoisting or lowering the load while movement in the L-R direction causes them to turn in the same directions, thus moving the load from side to side. Compound movements of the load can be brought above by moving the arms 3 to some position intermediate the four directions. The speed ratio of the two motors for any position of the arm 3 depends upon the angle between the linkage rods 4, 5. If the ratio is to be constant the angle must be 90 degrees. The motors may be changed over to separate control by switching the current to alternative control switches 12, 13.

Title: A method and a machine for producing moulded articles by injection moulding
IPC: B29C45/50
Filed: 1960-12-23
Abstract: 953,217. Injection moulding. H. GOLLER, and N, CHATELET, [trading as ANKERWERK GEB. GOLLER]. Dec. 23, 1960 [Dee. 24, 1959], No. 44217/60. Heading B5A. An injection moulding machine comprises a rotatable and axially movable screw 2, Fig. 1, which is tapered at its free end, the adjacent inner wall of the housing also being tapered. In operation the screw 2 is axially located in the position wherein the tip 24, 25, Fig. 5, closes the discharge opening 6 and is then rotated to plasticize the material present in the machine. The screw is then moved axially to establish an annular discharge gap 16 through which the plasticized material is fed to the mould 7, 8. When the mould is filled the resulting pressure reaction causes movement of the screw 2 to the right until the contact disc 18 actuates the switch 22 which causes stopping of the rotation of the screw 2 and, through the hydraulic jack 11, 12, the screw 2 is returned to its starting position so as to supply additional material under pressure into the mould to compensate for the shrinkage of the material in the mould during the cooling.

Title: Method of manufacturing beam lead integrated circuits
IPC: H01L21/00
Filed: 1970-09-17
Abstract: 1279167 Integrated semi-conductor devices ITT INDUSTRIES Inc 17 Sept 1970 [22 Sept 1969] 44419/70 Heading H1K A beam lead integrated circuit device is fabricated on a sandwich of a silicon substrate covered with aluminosilicate glass frit 2 in alcoholic suspension overlaid by a silicon wafer 3a the sandwich being placed between carbon susceptors of an hydraulic press and RF induction heated to 1200‹ C. under 1200 p.s.i., after which it is cooled under pressure. The wafer may alternatively be of germanium or gallium arsenide. It is parallel lapped or etched and polished to ¢ mil, and formed with a number of active or passive electrical components 4 by known photolitho masking, diffusion and deposition techniques. Alternatively the components may be preformed in the wafer, which is then applied to the substrate over a low temperature glaze and heated to a softening point lower than the diffusion temperature. A passivation layer 5 of evaporated silicon dioxide or RF glow discharge deposited silicon nitride is formed on the wafer, and holes are etched with NH 4 F + HF to expose terminals of the discrete components, and a metallized layer of e.g. aluminium is deposited by electron beam or filamentary evaporation or glow discharge. The required interconnecting lead pattern is formed by selectively etching with, e.g. NaOH through photoresist. Alternatively the lead pattern may be of a sandwich of Pt, Ti and Au in that order. Layer 5 is etched through photoresist with NH 4 F + HF to remove a portion surrounding each component, and abutting the leads 6. The exposed wafer surface is etched using HF+ HNO 3  + CH 3 .COOH to remove the exposed silicon to the glass layer and to undercut leads 6 without penetrating sufficiently under layer 5 to damage the components, which are thus isolated. The substrate may be divided using known scribing methods into separate integrated circuit devices.

Filed: 1974-10-16
Abstract: 1476738 Filling and twisting sausages ALBERT HANDTMANN 16 Oct 1974 [18 Oct 1973] 44923/74 Heading A2B [Also in Division F2] A pumping rotor 14 of a sausage filling machine is driven by a motor 13 through mechanism comprising differential means, such as a planetary gear train 20, and mechanism which converts rotary motion of the output shaft 25 of the differential means to intermittent motion, e.g. a crank mechanism consisting of a crank pin 33, connecting rod 34 and crank pin 35 on a crank 36 connected to the pump shaft by a one-way clutch 37, and a gear connection 28, 27 is provided between the pump shaft, which is held against reverse rotation by a one-way device 40, and the differential means with the object of enabling the size of portions delivered by the pump to be varied by adjustment of the throw of the crankpin 33 whilst minimising the time occupied by the return or non-pumping movements of the crank 36. A sun wheel 21 fast on the motor shaft 22 meshes with a part 29 of a stepped planet on a carrier 23 which is fixed to the shaft 25. The other part 30 of the stepped planet meshes with a sun 26 freely rotatable on the motor shaft and fast with the pinion 27. A clutch member 43 keyed to the shaft 25 may be engaged with a casing part 44 to hold the crank mechanism and thereby cause continuous rotation of the shaft 19 through the train 21, 29, 30, 26, 27, 28, or the clutch member 43 may secure a pinion 41 to the shaft 25 to introduce a further train 41a, 41, or the wheel 41 may be clutched to the shaft 25 by a one-way clutch on reversal of the motor. A turn-off or twisting arrangement 18 for separating individual portions of material delivered through a spout 17 is driven by a shaft 61, bevel gearing 60 and sun 49 of a planetary train 46. The sun meshes with a part 57 of a stepped planet on a carrier 48 driven from the motor shaft 22 through a train 52, 53, 54. A second input to the train 46 comprises an elliptical wheel 56 fixed, e.g. adjustably, to the shaft 25 and meshing with an elliptical wheel 55 rotatable on a shaft 59 and fixed to a sun 50 meshing with a part 58 of the stepped planet. In a modification the crank mechanism 33, 34, 35 and the one-way clutch 37 are replaced by mechanism with a member mounted on the shaft 25 and having a cam groove which oscillates a follower connected through a steplessly variable gear with the pump shaft 19. It is stated that the planetary train 20 may be replaced by hydraulic differential means comprising, e.g. three pumpmotor units.

Title: Process for the Production of Organopolysiloxane Elastomer Coatings on Metals
IPC: B05D7/16
Filed: 1966-10-11
Abstract: 1,162,025. Polysiloxane coatings. WACKERCHEMIE G.m.b.H. 11 Oct., 1966 [11 Oct., 1965], No. 45341/66. Heading B2K. [Also in Division C3] In coating metals with silicone rubbers, the metal, particularly Cu or an alloy thereof, e.g. brass, or a Cu object having soldered joints, is coated as by casting, immersion or roller coating techniques, with a room temp. curing composition comprising (1) a hydroxy-terminated diorganopolysiloxane, (2) a silicon compound containing at least 3 Si-bonded-OR radicals (R being a monovalent hydrocarbon radical that may be substituted and/or interrupted by ether oxygen atoms) and/or Si bonded H atoms, (3) a metal salt as condensation catalyst, and (4), as an anti-corrosive additive, an organic compound containing C, H, N and S atoms, and optionally O atoms, (see Division C3).

Title: Information storage systems
IPC: H03K17/78
Filed: 1966-10-11
Abstract: 1,104,163. Optical information storage system. INTERNATIONAL BUSINESS MACHINES CORPORATION. 11 Oct., 1966 [14 Jan., 1966], No. 45364/66. Heading G4A. An optical information storage system includes scanning means responsive to binary address signals for illuminating a selected area of an optical information record by deflecting a light beam appropriately over the record, and monitoring means responsive to the parity of each address applied to the scanning means for subtracting the emanation from the selected area of the record from that from another similar area of the record to provide an information indicating output. High intensity light from a monochromatic light source 10 is passed through a collimating lens 12, through a linear polarizer and through an aperture in a plate to a first unit 14 of a light deflection unit 14 including a plurality of deflection stages. Each stage comprises a birefringent means (22, Fig. 2, not shown) preceded by an electro optic element which provides an output beam polarized either in a first direction or a second direction at 90 degrees to the first, the birefringent means allowing one beam to pass through normally but causing the second beam to be diffracted and to leave the means at a position spatially separated from the first beam. Deflection stages are arranged in increasing order of deflection by a factor of two, the unit 14 causing deflections in the x position being followed by a unit 16 causing deflections in the y direction. An optical memory is then read by the light beam. The light beam is directed to the appropriate spot in the optical memory by X position address and Y position address signals which are converted into X and Y switch addresses by exclusive OR circuits 24, 28, an address of 111 requiring a diffraction of 7 positions thus requiring a switch address of 001 since the operation of the first electro-optic element will leave the beam polarized such that all succeeding birefringent means will cause diffraction of the beam. Examination of the switch addresses shows that the parity of the signal indicates from which quadrant of the memory the light beam will emerge, e.g. if the y parity is odd the light beam emerges from quadrant 1 or 2, if even from 3 or 4. Parity check circuits 30, 32 emit signals X1, X2, Y1, Y2 (X1, Y1 for even parity) which are applied to AND gates 50, 52, 54, 56 which indicate which quadrant the light beam is in. The four quadrants are examined by photo-cells 36, 38, 40, 42, one to each quadrant with the outputs of 38, 40, examining quadrants 2, 3 being applied to one difference amplifier 44 and the outputs of the other photo-cells being applied to a difference amplifier 46. It is assumed that the quadrants 1, 4 have the same noise signal produced by extraneous light, and similarly for quadrants 2, 3 so that the difference amplifier acts to subtract the signal due to noise from the data output signal. The resulting signal is then applied via inverters I, if necessary, AND gates 58, 60, 62, 64 and OR gates to the output.
