Title: Improvements in and relating to pressure-fluid actuated piston-devices
IPC: B67C3/24
Filed: 1946-12-02
Abstract: 631,332. Hydraulic rams. AKTIEBOLAGET ALKAALUMINIUMKAPSLAR. Dec. 2,1946, No. 35698. Convention date, Dec. 1, 1945. [Class 69 (ii)] [Also in Group XXVIII] In a fluid-pressure-operated double-acting piston-device for raising and lowering bottles in bottle-treating machines, such as capping-machines, comprising a fluid-pressure cylinder, a differential-area piston therein, a piston-rod carrying at its end remote from the piston a bottle support, a number of channels allowing fluid-pressure communication between the pressure source and the upper part of the cylinder, and a control valve, preferably in the form of a slide valve, in the base of the cylinder, the valve is adapted to place the non-annular side of the piston in communication alternately with the pressure supply and to exhaust or atmosphere, whilst maintaining the smaller or annular side permenently under fluid pressure. An outer tube 24 attached at its top end to a disc 14, houses an outer cylinder-jacket 1, the latter being secured to an inner cylinder-jacket 3 so arranged as to form an annular fluid-space 8 between the two jackets. The tubular piston-rod 12, which is spaced from the inner cylinder-jacket 3 to form an annular chamber 18 that communicates with the fluid space 8 through a port 17 in the inner cylinder-jacket 3, has the differential piston 2 at its lower end. The disc 14 and piston 2 are connected by a spindle 33, the lower end 35 of which protrudes so that in the bottom portion of piston travel it throttles a duct 27 and at the same time provides a pistonassembly air-buffer. When the disc 14 is to be lifted, the slide valve 26 is moved to connect fluid under pressure from a supply conduit 21 through duct 23, valve chamber 25 and the duct 27 to the space below the piston 2. The supply conduit 21 is permanently connected to the fluid space 8 through one or more channels 22. To lower the disc 14 the slide valve 26 is returned to its original position and the space below the piston is connected with a reservoir (not shown) by means of a duct 29; the pressure on the upper piston-surface 19 lowers the piston assembly at a rate which is controlled by the slide valve. The slide valve 26 is cam-operated.

Title: Improvements in and relating to grinding machines
IPC: B24B53/04
Filed: 1932-12-16
Abstract: 395,253. Grinding-machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Norton Co. ; New Bond Street, Worcester, Massachusetts, U.S.A.) Dec. 16, 1932, No. 35730. [Class 60.] Trueing rotating tools; wheels. - Work of non-circular contour, such as a rotary or sliding cam, is ground without relative movement of the grinding wheel and work towards and from each other by first shaping the wheel so that its operative contour is complementary to that of the finished work piece and then rotating the wheel and moving the work-piece in synchronism at different surface rates so that the same portion of the wheel cyclically and repeatedly grinds the same portion of the work piece. A grinding wheel 11 is driven by a gear 36 meshing with a worm 35 driven by an electric motor 27. On the shaft of the worm 35 is slidable a worm 38 meshing with a gear on a shaft 41 rotating the work. The slidable connection allows the wheel to be fed toward and from the work by a hand-wheel 25 geared to a screw 21 engaging a half nut 20. A spiral gear 54 on the shaft 41 drives a gear 55 connected by a telescopic shaft and universal joints with a gear 65 driving a shaft 68, the shafts 41, 68 rotating at the same speed. The shaft 68 rotates the pattern 49 to be copied in contact with a plunger 47 carrying a diamond 46 for shaping the grinding wheel before grinding, or trueing it after a period of use. The plunger 47 is held in contact with the pattern by a spring plunger 50. This mechanism is fed towards the wheel as the shaping or trueing proceeds by a hand-wheel 75 and may be traversed laterally by a hand-wheel on a screw 80. A plurality of trueing mechanisms and grinding wheels may be used in one machine for grinding autocar cam-shafts. The invention is applicable to the forming of irregular surface contours on reciprocatory bodies and internal surfaces and on the side surfaces of annular bodies. Specifications 6784/01 and 147,679, [both in Class 60, Grinding or abrading &c.], are referred to.

The crucible has a central depression (38) and outer grooves (40) Figs. 2-7 (not shown).  In a modified form the metal strip is bonded to slots on either side of the crucible Figs. 8 and 9 (not shown).  A further embodiment Fig. 10 (not shown) comprises a stack of boron nitride annular shaped members on a boron nitride disc with a Mo spacer between each member and aluminium spacers between the Mo and the ceramic.  The evaporating apparatus shown in Fig. 11 comprises an annular member 57 with the rim of the lamp reflectors abutting the sealing gaskets 58 positioned about the periphery. The evaporator 36 is held between a fixed member 64 and a spring-loaded member 66 and is held under tension by spring 68.  The aluminium source is placed in the crucible 20 in strip form and after evacuation the Mo strip 22 is resistance heated to 1500 DEG C. to flash evaporate the aluminium. The Mo strip is held under tension during heating and cooling.  In an alternative arrangement the aluminium is first melted in the crucible to wet and impregnate the crucible prior to its insertion in the evaporating apparatus 57.

Title: Method and arrangement for producing a switch signal
IPC: B60T8/1761
Filed: 1974-08-22
Abstract: 1483258 Antiskid braking systems TELDIX GmbH 22 Aug 1974 [22 Aug 1973] 36997/74 Heading F2F [Also in Division G4] A signal is produced on output 5 (Fig. 1) when the instantaneous digital value at input 1 deviates from the digital value stored in store 3 by a predetermined amount. As described the output of a delay element 7, triggered initially by a signal on line 9 resets a bi-stable 6, if it is set, and permits storage of a signal at terminal 1 representing for example vehicle speed. If during a time interval T 1  (representing a first delay value of the element 7) the stored value exceeds the instantaneous value by an amount #V 1 , e.g. at time t 2  (Fig. 2, not shown) comparator 4 delivers a signal on output I to bi-stable 6 to (1) produce the output signal 5, (2) cause the new value at terminal 1 to be stored, (3) switch the comparator to detect a smaller deviation #V 2  and (4) switch the delay element 7 to a second smaller delay interval T 2 . If, subsequently, during a time interval T 2  the deviation exceeds #V 2 , e.g. at time t 3  an output II from comparator 4 restarts the delay and allows a new input to be stored in store 3. This process is repeated until the value #V 2  is not exceeded during the time T 2  when the output of the delay at the end of this interval resets the bi-stable. This results in the comparator being returned to detect a deviation #V 1  and the delay being switched to its first value T 1 . A new time period is also started if the instantaneous value reaches the stored value, the comparator then emitting a signal on output III to reset the bi-stable. The apparatus is preferably used in an anti-lock system for giving a signal representing the deceleration of a vehicle.

Abstract: 1,116,022. Zone-melting. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. 24 Aug., 1966. No. 38062/66. Heading B1S. [Also in Division H1] A zone melting technique for producing mercury-doped germanium is carried out in a vessel containing mercury vapour sealed by a plug of liquid mercury located close to the vessel in a tube communicating with it. The vessel is a silica tube 13 in which a boat 1 carrying a monocrystalline germanium seed 3 and a supply of germanium 2 is placed. After connecting up to a tube 7 communicating with a system for providing vacuum or nitrogen under pressure mercury is introduced into the lower end 6 of the silica tube, which is then evacuated from end 5 and sealed. In operation the tube is uniformly heated to about 600C while the molten zone is produced by movable heater 15. The vapour pressure of mercury in the tube determines the doping of the resulting germanium monocrystal and is determined by the position and thus the temperature of the mercury liquid/vapour interface which is preset by the nitrogen pressure applied to the plug. Any tendency for the pressure to vary is compensated by movement of the interface to a hotter or colder location, the constricted section 8 of the tube serving to damp sudden variations.
