Abstract: 1,232,064. Change-speed gears; friction clutches multi-disc brakes and cooling thereof. U.S INDUSTRIES Inc. 11 July, 1968 [12 July, 1967], No. 33214/68. Headings F2C, F2D and F2E. A two-speed gear, particularly for a metal drawing press, comprises pinions 23, 24 fast on an input shaft 2 and constantly meshing gear wheels 25, 26 which are free on and selectively clutchable to an output shaft 3 by a fluid (preferably hydraulic) actuated, wet, multiplate, friction, double clutch 13, 14. The latter comprises a common spring-centred presser member 48 axially guided so as to rotate with the output shaft 3 and forming a cylinder 51 which together with a piston rib 52 of the output shaft provides two chambers selectively energized or vented, for clutching the gear-wheel 25 or 26 to the output shaft, through a rotary union 66 and output shaft passages 62-65. A multiplate friction brake 15 for the output shaft is applied by pistons 74 rightwardly urged for brake application by springs 84 and leftwardly urged for release by fluid fed through passages 85, 87. Cooling and lubricating oil is fed through an inlet 88 and output shaft passages 95, 96 to the clutch and brake plates through passages 99 and output shaft bearings 7, 8 through passages 105, the discharged oil flowing downwardly to cool and lubricate the other parts of the gear and being discharged through a casing bottom outlet (109). Preferably, the flow rate is such that the lower portion of the casing fills to a level such that the pinions 23, 24 are oil bathed and act as splash rings. A flywheel 10 on the input shaft may be driven by a belt. In operation, the output shaft brake is released before the double clutch is operated to engage either of the two speeds. To brake the input shaft, either side of the clutch is engaged and the brake applied.

Abstract: 1,233,372. Pipe couplings. MANNIN ENG. Ltd. 15 July, 1968 [26 Aug., 1967], No. 39371/67. Heading F2G. A screw-threaded member 5 surrounds a pipe 9 and is adapted for threaded engagement with a body 7 bored to receive the pipe, the member having an internal rebated portion 8 disposed intermediate and spaced from the ends of the member, and there is a tapered split collar 11 for engagement with a corresponding taper 10 on an inner surface of the member 5 to permit contraction of the collar into gripping engagement with the pipe. The collar is attached to the member 5 by engagement with the rebated portion 8 of the member, and a separate, non- split, sealing device 14 to effect sealing engagement between the pipe and the body is attached to the split collar utilizing the split in the collar for sprung engagement of the sealing device with the collar. As shown, the split metal collar 11 has a roughened, toothed or serrated inner surface 21 and a lip 16 which is sprung into a recess 15 formed in the metal sealing ring 14; the latter has a tapered surface 18 to engage an internal chamfer 19 of the body, and a tapered surface 23 which contacts a corresponding taper 22 on the collar. The screw-thread 6 of the nut 5 is an interference fit with the collar so that the collar, when contracted, passes into and is retained in the rebate 8 of the nut. In a modification, a non-metallic sealing member 14 is attached to the collar by an intermediate non-split carrier which contacts the surface 19 to prevent undue compression of the sealing member, the carrier having an inwardly projecting annular rib, or a separate element, which prevents extrusion of the sealing member. The nut 5 may be replaced by an externally screwed, hollow stud adapted to be screwed into the body 7.

[Also in Division H5] An X-ray spectrograph comprises an X-ray tube RR for exciting characteristic X-rays of elements of high atomic numbers in a specimen P and an electron gun EK for exciting characteristic X-rays of elements of low atomic number, the emitted X-rays 3 passing through a collimator K to an analyser crystal AK and a detector D. An apertured plate PL is disposed in front of the X-ray tube RR and is movable along three orthogonal axes from outside the tube, either manually or by means of electric motors. Movement of the plate PL in two directions alters the part of the specimen P bombarded by the X-ray beam 1, and the instantaneous position of the beam may be recorded automatically by means not shown: movement in the third direction varies the area of the specimen which is bombarded. Similarly the deflection plates A and B allow the electron beam 2 to be directed at the same part of the specimen, and a focusing coil M allows the size of the beam to be adjusted.

Abstract: 1,250,554. Hydrostatic steering mechanism. DANFOSS A.S. 18 April, 1969 [23 April, 1968], No. 19851/69. Heading B7H. Hydrostatic steering mechanism comprises first and second steering motors 9, 19 having their outputs 10, 20 coupled in parallel to a lever 11, a control unit 4 including a metering device actuated by a steering wheel 5 to pass hydraulic fluid under pressure to the first moror 9, and a valve 15 which is actuated by pressure-differential measuring means 21 to control application of pressure fluid to the second motor 19 in dependence on the pressure drop across the first motor 9. The second motor 19 is larger than the first motor 9 so that the control unit 4 need handle only a small proportion of the total volume of fluid flowing to the motors. Pressure fluid is supplied to the control unit 4 and to the valve 15 by separate pumps 1, 13. If the pump 1 is inoperative the valve 15 is actuated by the pressure drop created across the first motor 9 by manual operation of the metering device in the control unit 4, and if the pump 13 is inoperative emergency control can be by the first motor 9 acting alone. The valve 15 may be a rotary slide valve, and the motors 9, 19 may be of piston and cylinder or rotary type.

Abstract: 1,257,882. Electro-photographic copying apparatus. KOMBINAT PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Jan 23, 1970, No.3430/70. Heading G2H. Electro-photographic copying apparatus comprises a line-by-line scanning arrangement which repeatedly scans the original until a pre-set number of copies has been made. As shown, a motor 1 drives a xerographic drum 2 and, through an electromagnetic clutch 3, drives a cam disc 5 having a collar 4. Cam 5 reciprocates an arm 7 which scans a lens 9 across a micro-film original 8. At the end of each scanning cycle, cam 5 closes a switch 10 energizing an electromagnet 11, which moves counting mechanism 12 on one, and energizing an electromagnet 14 which holds a lever 15, preventing it from entering a slot 16 in collar 4 which would release switch 17 and de-energize the clutch 3. When the selected number of copies has been made, a lever 18 pivots against a lever 20 opening a switch 13 to prevent energization of electromagnet 14. Thus lever 15 enters slot 16 halting cam 5 and de-energizing clutch 3 to terminate scanning.

Abstract: 1,264,288. Semi-conductor integrated circuits. RCA CORPORATION. 7 Sept., 1970 [17 Sept., 1969], No. 42706/70. Heading H1K. An integrated circuit comprises (Figs. 1, 2) a substrate 12 of first type e.g. P conductivity overlain by epitaxial layer of second type conductivity having surface 14; an isolation layer 16 of first type e.g. P conductivity being diffused through portions of the epitaxial layer to divide it into zones 18, 20 of second e.g. N- type conductivity separated by isolating PN junctions. Zone 18 includes a device for isolation e.g. a NPN transistor 21 whose collector is part of zone 18, base is a region 22 of 1st type conductivity, and emitter is a region 24 of 2nd type condutivity; an insulant layer 26 being deposited on the epitaxial surface and selectively removed to open portions of regions 18, 22, 24 after which a conductive layer of e.g. aluminium is deposited and selectively removed to leave interconnecting leads 28, 30, 32. A bonding pad 34 is vacuum deposited on layer 26 and connected to region 22 by metalized lead 32; the lead and pad being disposed over the area of zone 18. An inversion channel 36 of P-type conductivity will form in zone 18 under the lead and bonding pad at approx. 20 v.p.d. to intersect and extend P-type region 22, but since the lead and path are disposed on insulant layer 26 within the area of zone 18, the channel cannot connect region 22 with isolation region 16 and so short the transistor. Similarly (Fig. 3) zone 20 includes resistor 38 by diffusion of a 1st type region into part of zone 20 from surface 4, and part of the insulant layer 26 is removed to expose the resistor, which is connected over lead 42 to bonding pad 40 both disposed on the insulant layer. Z arc 20 is extended at 20b, 20c to include the lead and pad, and thus prevent shorting from the resistor to the substrate by the formation of an inversion channel 44.

Abstract: 1290062 Bioflocculation CESKOSLOVENSKA AKADEMIE VED 9 Dec 1970 [11 Dec 1969] 58472/70 Heading C1C A treatment of polluted liquids consists of subjecting the liquid to bioflocculation in a closed space, withdrawing part of the liquid with the thus created suspension and allowing this to sediment by gravity in an inclined sedimentation channel, taking a first stream of liquid with a diluted suspension from an external part of the channel for filtering through a fluidized sludge blanket, directing a second stream of concentrated suspension by gravity from an internal part of the channel back into the bioflocculation space and withdrawing liquid from the sludge blanket. The treatment may be carried out in the apparatus of Fig. 1 wherein the polluted liquid enters the bioflocculation space A at the supply means 4 and has dispersed therein, an oxidizing gas injected at the jet 5. A mechanical agitator 10 imparts a helicoidal motion to the mass of liquid in the bioflocculation space. Some of the circulating liquid enters the sedimentation channel S via the distributing trough T. The solids in suspension in this liquid gravitate and concentrate along the partition wall 8 and return to part A 1  of A. Water with diluted suspension enters via openings 9 the space B in which there is a sludge blanket for filtering said liquid; clarified liquid is withdrawn by troughs 18 to collecting channel 3.

Abstract: 1297268 Wave propagating media LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 23 Dec 1969 [30 Dec 1968 29 Jan 1969] 62621/69 Heading H1W A so-called "artificial dielectric medium" comprises elongated, thin-film conductive elements 1, Fig. 1, located on parallel surfaces defined by dielectric sheets (not shown), the elements on any surface being staggered with respect to those on adjacent surfaces, the medium being intended for propagation in a TM mode with the surfaces containing the elements parallel to the direction of propagation Z. The thickness of the dielectric sheets is of the order of a few microns and the elements are made as thin as possible, e.g. until loss due to eddy currents is about 0À3 times the ohmic losses. In one example, the sheets are made of polystyrene 0À22 micron thick and the elements 1 of aluminium foil 6 microns thick. The Specification contains an extensive theoretical discussion on the relationship between losses and the thickness of the conductive elements. The medium is dielectrically anisotropic and the Specification discusses at length its propagation properties. The medium may be used to form the inner conductor (Fig. 7) of a coaxial line by helically wrapping about a dielectric core 3 a polystyrene band 2 bearing a coductive pattern 1<SP>1</SP>, 2<SP>1</SP> in such a manner that the conductive areas 1<SP>1</SP> overly the non-conductive bands 2 in successive layers. Modifications are described (Figs. 8, 9, not shown), in which the pattern provides continuous or staggered longitudinal non-conductive bands. The outer conductor (not shown) may be of normal construction and may be spaced from the inner conductor by a low-loss dielectric, e.g. a gas. The modified inner conductor may be matched to a normal inner conductor by a series of steps (Fig. 12, not shown). The permittivity of the medium in the (longitudinal) direction OZ may be measured using the apparatus of Fig. 4 in which contact is made to the extremities of a stack 1 by electrodes 8 electrically connected to shortcircuits 9, 9<SP>1</SP>. The conductor 9 is connected to conductive shields 6, 6<SP>1</SP> spaced from the stack by insulators 7, 7<SP>1</SP>.

Abstract: 1302991 Deoderizing vegetable protein. RALSTON PURINA CO 19 April 1971  9985/71 Heading C3H . The flavour of a vegetable protein isolate is improved by heating an aqueous slurry of the isolate to above 220‹ F. at a pH below 8 and subjecting the slurry to momentary physical washing, e.g. simultaneously, retaining the heated and washed slurry under a pressure sufficient to prevent volatilization of water therefrom, suddenly releasing the pressure, whereby water laden with odiferous materials is vaporized, and separating the vapour from the slurry. Examples of vegetable protein isolates are those derived from oilseeds, e.g. soybean, peanut, linseed, safflower seed, cottonseed, sesame seed and sunflower seed. The heating and momentary washing may be carried out in a so-called "jet cooker". The product is suitable for use in the food industry in a variety of foodstuffs.

Abstract: 1312045 Anti-skid control systems MULLARD Ltd 27 April 1970 [27 June 1969 6 Aug 1969] 32612/69 and 39417/69 Heading F2F An anti-lock vehicle brake system comprises a wheel movement sensor 6 and an electrical control arrangement 7 operable on a control valve 5 to reduce fluid braking pressure at a wheel brake 10 upon a predetermined rotational movement of wheel 11 being attained, e.g. deceleration indicative of a skid, and a fail-safe arrangement 1 which on prolonged actuation of the valve 5 is responsive to the value of the braking pressure to override the action of the valve 5 to allow the braking pressure to be increased and restore braking. As shown in Fig. 1, the system is hydraulic and includes a master cylinder 2; action of the valve 5, upon a skid being sensed, causes pressure from lines 15 and 16 to be diverted to line 17, from whence it enters a reservoir 18 of a variable restrictor element 8 to be applied to a spring-loaded plunger 19 to move it to the right to restrict fluid flow between a line 14 and line 15. A pump 9 driven by the wheel 11 returns fluid from the reservoir 18 to the line 14 but if the valve 5 remains open fluid pressure in reservoir 18 will flow via line 27 to operate on area A2 of a piston member 24 of the fail-safe arrangement 1. The piston member 24 then moves to the left to bring an O-ring 28 out of sealing engagement with passage 29 and allow master cylinder pressure to flow via lines 27, 17 and the opened valve 5 to the brake 10. A restrictor 31 is included in passage 29 to prevent movement of piston-member 24 during normal braking. A pressure line 26 between the restrictor element 8 and chamber 23 of the fail-safe arrangement 1 may include a restrictor means to lower the fall of pressure in chamber 23 upon operation of the valve 5, see Fig. 1 of Application No. 39417/69 (not shown).
