Title: Improvements in sheet metal buildings
IPC: E04B1/61
Filed: 1939-08-24
Abstract: 545,570. Metal walls, floors, roofs and ceilings; portable buildings. BACHER, M. A., [Representative of BACHER, G. E.] Aug. 24, 1939, No. 24373. [Classes 20 (i), 20 (ii), 20 (iv) and 87 (i)] Hollow sheet metal units for walls, partitions, floors &c. are formed from opposed plates each provided with edges bent at right angles which abut on adjacent plates and further bent portions which interengage these edges being spaced apart on the opposed plates. The edges of plate 1 are bent inwardly at right angles to form an abutting portion 3 and again inwardly to form an inclined portion 4 while the edges of coacting plate 2 are bent inwardly at 6 and again at 7 into a bead which interengages with the inclined portion of the adjacent plate. The inclined portion 4 may terminate in a further bent in portion to enclose the bead on the adjacent plate. Spring strips 13 may be fitted over opposed inclined portions of plate 1 or inside the beads 8 of opposed plates and the inside of the panels may be filled with sound deadening or insulating filling 18. The hollow panels may be formed from bent sheet metal with one open side or wholly closed and the edges of the panels are shaped to form abutting and interengaging portions. These shaped portions may be undercut and may pravide drainage channels 15, Fig. 10, between the units. Partitions are joined to main wall sections by forming the plates of the main wall with recesses 127, Fig. 17, to receive the projecting edges of the end plates 128 of the partition. Angle-shaped hollow units are used at the corners of the building. The ends of the units are received in plates of channel, angle or Z-section which may be provided with shaped portions to form skirtings and picture rails. Windows and door frames are formed as hollow sections with one edge shaped to interfit with the panels and the other edge recessed to receive the window or door. For roofs, the units may have the faces inclined towards one or both ends so as to form a horizontal ceiling and an inclined roof.

Title: Document reading system
IPC: G06V30/224
Filed: 1960-07-14
Abstract: 890,445. Sensing statistical records. SPERRY RAND CORPORATION. July 14, 1960 [July 17, 1959], No. 24546/60. Class 106 (1). Data is recorded on a document in two forms, as a visually readable character, e.g. a numeral and in a coded form 7, Fig. 1, by means of a combination of parallel bars 9, the character being formed of a number of sections so as to provide timing marks for reading the coded part 7. Each character is formed by blocks 10, 11, 12, &c. in five positions and the code bars 9 occupy combinations of these positions. Both parts are sensed when the document passes under a reading station, there being a narrow magnetic head 13 for the coded part 7 and a broad head 14 for the legible part 8. This compensates for vertical out-of-alignment. The code marks 7 are used to derive long pulses which are applied to a gate, the other input is in the form of short timing pulses from the part 8. The character is thereby read out in a serial coded form. The use of long gating pulses derived from the code marks 7 compensates for skew of the document as it passes through the reader, these pulses being provided so as to begin before and end after the short timing pulses. The signal from the reading head 13 is amplified at 32, Fig. 3, to give a number of approximate sine wave cycles Z1, Z2 and Z5, wave A, Fig. 5. This signal is squared and clipped at 33 (wave B) and differentiated at 34 to give peaks, wave C, coincident with the zero crossing-points of wave A. The waveform C is applied to a rectifier 35 and an inverter 36 so that wave D is obtained. A double trigger circuit 37 produces a long pulse from each pulse in wave D so that the gating signal E is produced. The timing marks produce signal F in head 14 which after clipping at 43 (wave G) and differentiation at 44, give pulses as shown in wave H. These are rectified at 45 (wave I) and inverted at 46 to give wave J. A multivibrator in block 47 produces a pulse for each input pulse, the length of which is approximately half the interval between timing pulses so that the wave K is obtained. Upon differentiation (wave L), rectification and inversion the waveform M is produced in which the pulses are, in effect, the timing pulses delayed by about half a cycle. When these pulses are applied with the long pulses E to gate 38 the coded representation N of the sensed character is produced. The circuits are shown and described in more detail.

Title: Improvements in or relating to exothermic mixtures and the use thereof
Inventor: WATSON ALBERT RALPH
IPC: B22D27/06
Filed: 1960-07-14
Abstract: An exothermic composition, in the form of a shaped solid mass, for lining the riser cavities, feeding head cavities or head boxes in the production of metal castings or ingots, comprises finely-divided aluminium, an oxidizing agent, e.g. alkali metal nitrate or chlorate, manganese dioxide and/or iron oxide, preferably in a stoichiometric insufficient amount, a refractory filler such as sand, grog or crushed firebrick, and a resinous binding material consisting of or containing a water-insoluble furan resin.  The composition may further contain a catalyst for hardening the resin, such as one or more of ammonium chloride, sugar, urea, aluminium phthalate, sodium dihydrogen orthophosphate, acid aluminium phosphate, and/or ammonium thiocyanate, carbon black, e.g. 1 to 15% by weight, 0.1 to 15% by weight of a fluoride such as NaF, sodium or potassium aluminium fluoride, and green strength additives such as gum arabic or dibutyl phthalate.  The shaped solid mass may be produced from a powdered composition which contains, besides the aluminium, oxidizing agent and refractory filler, a precursor for the water-insoluble furan resin, which forms upon heating; at least one of the reactants needed to form the resin is included in the powdered composition.  Other resins, e.g. urea-formaldehyde or phenol-formaldehyde resins, may be mixed with the furan resin or precursor thereof, e.g. furfural, furfuryl alcohol, furfuramide or tetrahydrofurfuryl alcohol; the furan resin may be a condensation product of furfural with a phenol, amine, aldehyde or ketone, catalysed by acids or alkalis.  Reducing agents additional to aluminium may be employed, e.g. ferrosilicon or carbon.  Specification 627,678 is referred to.

Abstract: 1374729 Steering column locks NISSAN MOTOR CO Ltd and KANTO SEIKI CO Ltd 23 May 1973 [31 May 1972] 24607/73 Heading B7J [Also in Division E2] In a steering-column lock, Figs. 1 and 2, in which the lock cylinder turns a cam 24 which lifts the bolt 12 and has a projection 27 controlling the electrical switch 20, rotation of the key past the 'ACCESSORIES' position causes a projection 48 on the cylinder to engage a projection 47 on a ring 36 to turn it so that a spring-loaded pin 34 is disengaged from a recess 46a and forced along into a recess 26a in the cam to prevent accidental return of the key to the locking position until the ring 36 is turned back manually. When the key is turned to the 'START' position, the ring 36 is rotated to a position in which the pin 34 engages a minor depression 46b so that the ring is held in a position in which rotation of the lock cylinder 18a back past the 'ACCESSORIES' position to the 'LOCK' position is prevented, therefore, to lock the steering column, the ring must first be turned back manually to allow the pin to enter recess 46a to clear recess 26a on the bolt cam so that this can move back to the fastening position. In a modification, Fig. 10, a resilient or spring-loaded lever 100 enters a slot 98 in the bolt 12 to hold it retracted until the key is withdrawn.

Title: Improvements in and relating to carburetors
IPC: F02M1/04
Filed: 1922-09-11
Abstract: 209,781. Stanton, W. F., and Verto Products Co. Sept. 11, 1922. Spray carburettors.-A head of fuel above the level of the supply in the float chamber is maintained in a chamber open at the top to the mixing-chamber at a region where the suction is steady and unaffected by the inflowing air, and spraying is produced at a point remote from this chamber by the velocity of the air for the formation of the mixture. The suction-actuated air valve 10 is provided with a tubular opentopped stem 15 up which the fuel is drawn by the steady-suction above the valve, the fuel being then drawn through a series of passages 102 and sprayed at the rim of the valve by the inflowing air. The supply of fuel to the stem 15 is controlled by a hand-operated valve 43 surrounded by a filter 58, and by a sleeve 26 connected' to the stem 15 and controlling narrow fuel-inlet slits 27 in a fixed sleeve 25. A dashpot piston 17 submerged in fuel is attached to the stem 15. A fixed post 23 carried by a crossbar 24 in the mixing-chamber C projects into the stem 15; the capacity of the stem is thus reduced as the air valve 10 lifts, and an excess of fuel is ejected for accelerating. Warm air is supplied through an inlet D opening into an annular chamber B, the supply being controlled by a rotatable shutter 38. To adapt the carburettor to different engines, the chamber B is rotatably mounted, bearing against the air valve seat 13 and against a flange 37 attached to the seat 13 by posts 36. Cold air is admitted through an annular passage 39 when a sleeve 41, attached to the air valve by posts 19, is raised above a flange 40. Any fuel which accumulates above the air valve is either drawn through the passages 102, or is drawn through ports (not shown) in the post 23 and in the stem of the throttle valve 11, to a passage 110 provided with outlet apertures 111. Fuel for starting is supplied to the mixing-chamber C through a passage 51 and port 52 in the cross bar 24, the inlet to the passage 51 being controlled by a spring-pressed' sleeve 49. The sleeve 49 is lifted, to align a port 53 therein with the passage 51, by raising the fuel valve 43, the stem 45 of which, when raised, abuts against the sleeve 49. The stem 45 is hollow and is provided with fuel inlet ports 48. Back pressure on the fuel, and' consequent lag in its flow, due to the pulsations in the induction pipe, are prevented by a normally-open hinged valve 60, which when' closed protects the seat 44 of the fuel valve 43. In a modification, the air valve 10<a>, Fig. 4, has air passages 10<c> at its rim adjacent the fuel passages 10<b>.

Title: Frequency selective valve apparatus
IPC: H03F3/189
Filed: 1949-09-26
Abstract: 674,252. Valve amplifying circuits. EDISON SWAN ELECTRIC CO., Ltd., and POCOCK, S. N. Aug. 9, 1950 [Sept. 26, 1949], No. 24652/49. Class 40 (vi). In a selective amplifier in which a first amplifying valve 2 feeds a cathode follower 6, the load circuit of valve 6 includes an R.C. network selective to a desired frequency which is connected to a grid of valve 2 to provide positive feed-back at that frequency. The signal appearing at variable potentiometer 13 is applied in phase with the input to valve 2. Adjustment of shunt resistor 12 varies the frequency selected while the setting of potentiometer 13 alters the selectivity, the output being taken from the junction of isolating resistor 19 and resistor 20. A D.C. feed-back path between the cathode of valve 6 and the screen grid of valve 2, decreases the output impedance of valve 6 and reduces distortion. The selected component may be integrated by feeding it to the grid of pentode 21, Fig. 2, having a capacitor 23 in the anode circuit. The standing anode currents may be adjusted by moving the contact on potentiometer 27. The contact potential between grid and cathode of valve 21 is balanced by a corresponding potential developed by diodes 31, 32 so that the effect of variations in the contact potential due to heater voltage changes are minimized. The average of the charge acquired by the capacitor 23 over a number of successive charge periods may be determined by discharging the capacitor 23, Fig. 3, through a switch 39 and resistors 37, 46. During the discharge, the averaging capacitor 41 receives a charge which is arranged to be a desired integral fraction of the charge on capacitor 23 by appropriate setting of the tap on resistor 43.

Title: Generator control circuits
IPC: H02J1/10
Filed: 1972-05-25
Abstract: 1437087 Automatic control of generators LUCAS INDUSTRIES Ltd 17 May 1973 [25 May 1972] 24666/72 Heading G3R Each generator in a plurality of generators forming a parallel system is regulated by varying the current in its field winding in accordance with the output of a differential amplifier responsive to a reference voltage, a sawtooth voltage and the generator output voltage to produce a pulse width modulated wave train. The reference voltage is modified by a signal responsive to out of balance current between the generators. As shown, the current in generator field winding 11 is controlled by transistors Tl, T2, T2a, T3 which receive a square wave signal from a differential amplifier ICI. Input terminal 18 receives a reference voltage from Zener diode ZD2, while input 19 receives a proportion of the generator output voltage from potentiometer chain R31, RV2, R32 together with a sawtooth voltage produced by an oscillator comprising unijunction transistor T4 and capacitors C8, C16. The width modulation of the square wave tends to regulate the generator voltage. The reference voltage on terminal 18 may be varied by the output of a second differential amplifier IC2 which is responsive to current in an interpole winding 12 or a current transformer. If two or more generators are connected in parallel at the junction of resistors R29, R30, any unbalance will produce a current in the resistor R30 of each generator  control circuit, and the respective reference voltages will be changed by equal and opposite amounts so as to tend to restore current balance. The variation of the reference voltage on terminal 18 is limited by diodes D6, D7. A switch 15 is opened in response to over-voltage conditions sensed by a potentiometer RV3 connected to transistors T5, T6. Operation of switch 15 is inhibited by a discriminator circuit T7A, T7B if a generator associated with a parallel circuit is faulty causing amplifier IC2 to produce a high output.
