Patent GB-1237668-A (GB)
Title: Latch
Inventor: PLOUGHMAN LEONARD KAJ
IPC: E05B65/32
Filed: 1970-01-30
Abstract: 1,237,668. Latches. L. W. MENZIMER. 30 Jan., 1970, No. 4516/70. Addition to 1,202,293. Heading E2A. The vehicle door latch described in the main Patent is modified to allow keyless locking after depression of the sill button, by closing the door after only momentary instead of continuous depression of the outside push button. This is achieved by an over-centre spring 90 acting between the contactor 54 which acts as an actuator for the latch pawl 37 and the locking lever 67, in holes in each. In the unlocking position of the locking lever 67, Fig. 2, the end 91 of the spring engaging the contactor 54 urges this clockwise against the rod 50 connected to the outside button 46. Consequently, when the button is depressed, Fig. 3, and released the contactor returns to its former unoperated position. To lock the door without a key, the sill button is depressed to turn the locking lever 67 clockwise into its locking position via rod 76, Fig. 4. This moves the other end 84 of the spring into a position such that when the outside button is depressed, the end 91 of the spring passes over the deadcentre line b, Fig. 5, and the contactor snaps. into the operated position and stays there. The transmitter 65 is turned counterclockwise about stud 71 to pull the cancellation lever 66 upwardly to its inactive position out of the path of the finger 45 to allow the latch 21 to be locked as in the main Patent.

Abstract: 727,583. Automatic voltage control systems. KOEHLER MANUFACTURING CO. Feb. 20, 1952 [May 17, 1951], No. 4541/52. Class 38 (4). In Fig. 1 storage batteries Ba, e.g. for miner's cap lamps, are charged from bus-bars 10, 12 supplied through a transformer T1, and selenium rectifiers X from an A.C. source a, c. To maintain, automatically, constant bus-bar voltage with varying load, e.g. number of batteries connected, the voltage across a high resistance meter M connected to the bus-bars is applied, in opposition to a stabilized D.C. voltage produced from a D.C. source c<SP>1</SP>d across resistors rl, r2, to the input of a two-stage directcoupled D.C. thermionic valve amplifier V1, V2, the output of which controls a valve rectifier V3 supplying the D.C. winding Zd of a saturable reactor Z having A.C. windings Za1, Za2 in series with the supply to transformer T1. The bus-bar voltage desired is set by adjusting resistor r2 until the pointer of meter M coincides with a mark on the scale. A resistor R responsive to ambient temperature has a negative temperature coefficient so that bus-bar voltage varies inversely as ambient temperature to reduce charging time at low temperatures and charging rate at high temperatures. Operation with a resistor having a positive temperature coefficient is referred to.

Title: Method of and apparatus for monitoring the adsorption of sulphur compounds from gases and vapours
Inventor: BELL ERIC BRAYTON
IPC: G01N23/12
Filed: 1963-02-05
Abstract: 1,072,482. Radiation density gauges. SAUNDERS ROE & NUCLEAR ENTERPRISES Ltd. and GAS COUNCIL. May 1, 1964 [Feb. 5, 1963], No.4582/63. Heading G1A. In order to determine the extent to which a bed of absorbing material is still capable of absorption a radioactive source is placed to radiate through the bed and a detector recording or indicating the strength of the attenuated radiation used to provide information about the density of the material in the bed. The invention is described with reference to the purification of petroleum distillate before it is fed to catalytic gasification plant. Initially the distillate, which may contain sulphur compounds harmful to the catalyst in the gasification plant, is mixed in vapour phase, with hydrogen or a gas containing hydrogen and fed through a bed containing, for example, molybdenum as a catalyst. This causes the sulphur present to be almost completely converted to hydrogen-sulphide. The mixture is then passed through one or more absorption beds of iron oxide composition. Such a bed is indicated at 2 in a reaction vessel 3 which may be surrounded by a furnace 4 having heating elements 5 to maintain the required temperature of 330‹C. Owing to the rapidity with which hydrogen-sulphide is absorbed by the bed to form sulphide the active part of the bed is a relatively narrow band having completely used oxide upstream and almost unaffected oxide downstream. One or more fixed density gauges may be used to detect when the band reaches a given position or positions. In modifications a single gauge movable continuously or step-wise along the bed is used. When the gauging system determines that the bed is almost fully used its output may be arranged to operate valves to substitute a fresh bed. A plurality of absorption beds may be arranged in series in the vapour stream as described in Specification 1, 068, 588. The density gauge (or gauges) may comprise a Cs 137 radioactive source 13 on one side of the bed and a scintillation counter 12 comprising a phospor and photo-multiplier on the other. It is preferred to display the photo-multiplier output on a chart recorder. The yoke 11 supporting the units 12 and 13 may be movable along the outer casing of the bed. A suitable density gauge is more fully described in Specification 957,186.

Title: Improvements in filter systems
Inventor: BREAR JOHN HARRY
IPC: B01D35/12
Filed: 1965-02-03
Abstract: 1,128,912. Filtering system. SERCK R. & D. Ltd. 27 Jan., 1966 [3 Feb., 1965], No. 4655/65. Heading B1D. In a filtering system in which a bistable switching device 5, 11 automatically directs fluid alternately to each of two passages containing filter elements 3, 4 while causing backwashing of the element not on forward flow, the passages 1,2 form opposite sides of a central chamber 7 which communicates by apertures 9, 10 with passages 1, 2 upstream of elements 3, 4. The converging inlet 11 and subsequent divergence of the passages forms a bistable coanda, which switches the flow when blockage of one element alters the pressure distribution sufficiently. The backwashing stream through one element passes through chamber 7 where baffle 8 retains the solids. In Fig. 1 elements 3, 4 are separate and passages 1, 2 enclose the spherical or cylindrical chamber 7. In Fig. 2, not shown, the filter elements are different parts of a cylindrical element (12) located at the downstream junction of passages 1, 2, and flow is inwards through element (12) then out at its upper end.

Title: Improvements relating to sheet metal working presses
IPC: B21D24/08
Filed: 1932-02-18
Abstract: 388,203. Stamping-presses. GLASNER, R. W. and RODE, F. J., 6500, West 65th Street, Chicago, U.S.A. Feb. 18, 1932, No. 4790. [Class 83 (iv).] Cupping.-In a press for working sheet metal in which the movement of the pressure pad is yieldingly resisted by a liquid column acting in conjunction with a shock-absorber, the shock-absorber is associated with a combined check and relief valve which is actuated automatically to permit liquid to escape from the column and is opened during the return movement of the pressure pad to allow liquid to flow back into the column. The upper die 15 is mounted in a ram 13 which is reciprocated along vertical guides 11 by means of a crankshaft 12. Mounted on a bed-plate 16 is a die 17 co-operating with a work support 18 which is carried on pins 19 resting on a piston 21 actuated by a hydraulic cylinder 22. This cylinder communicates by a pipe 23 with shockabsorbing devices carried on a base 24 and comprising a cylinder 25 carrying a hollow plunger 26 which is connected to a piston 27 working in a cylinder 28. This cylinder supports a reservoir 30 receiving pressure fluid such as air from a pipe 32 fitted with a pressureregulating valve 33. In its lowermost position the plunger engages a shoulder 45 in the cylinder 25. The plunger is fitted with a valve 39 which is normally held on its seating by a spring 43 but during the upward movement of the plunger a collar 42 on the valve stem engages a fixed abutment 44 to cause the valve to be opened. In operation, as the die 15 approaches the work the parts are in the position shown in Fig. 1 and when the die engages the work the blow is cushioned by the liquid in the cylinder 22. As the upper die descends to the Fig. 2 position, liquid is forced through the pipe 23 moving the plunger upwards until the engagement of the parts 42, 44, opens valve 39 and allows liquid to pass above the piston 27. As the ram starts to ascend the pressure in the reservoir 30 forces the piston 27 and plunger 26 downwards, and valve 39 is closed until the plunger reaches the abutment 45 after which the reservoir pressure opens the valve 39 and allows fluid to flow back into cylinder 22 to return the member 18 to its normal position, Fig. 1.

Title: Apparatus for tensioning continuously moving strips
IPC: B65H23/188
Filed: 1973-01-31
Abstract: 1389963 Tensioning strip; rolling BWG BERGWERK UND WALZWERK MASCHINENBAU GmbH 31 Jan 1973 [21 July 1972 28 Nov 1972] 4860/73 Headings B3E and B3M [Also in Division B8] Apparatus for tensioning a continuously moving metallic strip 5 comprises a plurality of tension rollers 3, 4 connected via respective transmissions 10, Fig. 2, to a common shaft 8 and at least all but one of the transmissions being differential transmissions having inputs derived from the common shaft and from a respective variable torque motor 11. Tension rollers 3, 4 are connected to the shaft via bevel gears 9. The driving motors are adjustable to produce required torque for tensioning the strip and are preferably hydraulic motors connected to a variable pump (15), Fig. 3 (not shown), via a high pressure fluid line (14). In a modification, Fig. 4, the rollers are connected to the shaft via bevel gears 22 with one of the rollers 3 having a fixed ratio positive transmission 23. Torque motors 31 can be accurately adjusted and have transmission ratios of 1 : 100 to 1 : 1000 and the ratios of the speed of the motors to the roller 3 when the shaft is stationary may be from 100: 1 to 1000 : 1. The speed ratio of shaft 21 to the roller 3 with transmission 23 is different from that of shaft 21 to the speed of the other rollers with the motors 31 stationary. The strip 5 is fed over rollers 3, 4 and passes through stretching stand 6 using driving motors 17, 18 acting via transmissions 19, 20 on the rollers 3 of each tensioning stand. Alternatively, driving rollers (7), Fig. 1 (not shown), may provide continuous movement of the strip. The coupling together of the tensioning stands via the differential transmissions and variable torque motors allows the roller speeds to vary with respect to one another and therefore provides for the adjustment of the strip tension. In a further embodiment, Fig. 5 (not shown), a driving motor (32) is used to drive shaft 21, and driving motors 17, 18 and transmissions 19, 20 are omitted. Motor (32) drives roller 3 via transmission 23 with common shaft 21 providing the mechanical synchronization of the differential transmissions 24 adjusted to various torques. The variable torque motors may be electric motors, and the basic transmission ratio of the roller 3 connected to transmission 23 is from 0À5-1% higher or lower than that required to compensate for maximum stretching of the strip between the tensioning stands.
