Title: Bushings
Inventor: JORN RAOUL
IPC: F16C11/04
Filed: 1968-09-04
Abstract: 1,206,895. Elastomeric bush mountings. R. JORN. 4 Sept., 1968 [4 Sept., 1967], No. 42057/68. Heading F2S. A component, constituting the inner end intermediate sleeves of a bushing comprising an elastomeric sleeve sandwiched between inner and outer rigid sleeves, consists of a metal tube 1, Fig. 1, on which is bonded a rubber or like sheath 2, the ends of which project beyond the ends of the tube. In at least one (as shown, both) of the sheath ends is a groove 9 or 12 and at the, or one of the, grooved ends the sheath has an annular collar 3. Bonded to the axially inner face of this collar is a metal ring 4. Other features which may but need not be provided are: a second metal ring 7 on the outer face of the collar; further rubber 8 surmounting this second ring; an additional annular groove at the un-collared end of the sheath; and a tubular metal reinforcing element embedded in the rubber. These last two features are present in Fig. 2 (not shown). The bushing of Fig. 5 is assembled by fitting two of the Fig. 1 components into a metal sleeve 16 and axially compressing them by a bolt 27 until their rubber sheaths are the same length as their respective tubes 1. The bushing of Fig. 9 is assembled by precompressing the sheaths before the components are located between the cheeks 19a, 20a, which correspond to the frame elements 19, 20 of Fig. 5. The Fig. 9 bushing consists of two modified bush components of a form depicted in Figs. 6 and 7 (not shown) in which the ends of the inner tubes 1 are each adapted to receive a flange 30 for precompressing the collar of the sheath and a spring ring 31 for coupling the two tubes together in abutting relationship and so precompressing the other ends of the sheaths. Both the bushings shown are arranged to be stressed torsionally when a rod 17 attached to the outer tube 17 is turned about the axis of the inner tube 1.

Abstract: 1406194 Indoor games SEGA ENTERPRISES KK 7 Sept 1973 [31 Dec 1972] 42142/ 73 Heading A6H A coin-freed games apparatus comprises an opaque running surface 6 over which models 8, e.g. in the form of motorcycles can move; magnets 32 positioned underneath the surface 6 and movable, to impart a diversified motion to the models 8; a further model 7 movable under the control of a steering handlebar 4 operable by a player with the object of outrunning and avoiding collisions with the models 8; a projector 9 to project continuously moving images of a desired road pattern on to the surface 6 so that the models appear to be travelling along a road; and a carriage 12 for the magnets 32. The carriage 12 is mounted for linear reciprocation beneath the surface 6 and carries a rotatable disc 20 upon which are two revolvable shafts each carrying respective second discs 29, the magnets 32 being mounted on further revolvable shafts carried by the discs 29. Suitable drives, Figs 3 to 7 (not shown), cause the discs 20 and 29 to rotate and impart various motions to the magnets 32, and hence to the models 8, but the arrangement is such that the magnets always retain a particular orientation so that the models always appear to be moving in a predetermined direction despite their other movements.

Abstract: 1,009,536. Reciprocating pumps; Syringes. W. DAN BERGMAN A.B. Oct. 28, 1963 [Oct. 29, 1962], No. 42450/63. Headings F1A and FIR. [Also in Divisions F2 and H2] A reciprocating .pump used for supplying regular pulses of lubricant to a machine comprises a slow speed reciprocating motor which has the energising coil 1 supplied through a thermal switch 12 embedded in the winding (see Division H2). The core 3 of the motor is held in the position shown by spring 4 when coil 1 is de-energised and uncovers the connection between lubricant reservoir 13 and chamber 16. When the core 3 is pulled into the coil rod 8a is displaced to the right to pump the lubricant from chamber 16 through spring loaded ball valve 10a into feed pipe 20. The speed of the pump may be varied by altering the heat transfer characteristics of the coil. The reservoir 13 which employs spring loaded plunger 17 to pressurize the liquid may be replaced by a container having an elastomeric wall, Fig. 4a (not shown), if the pump is used in a situation where an external pressure is present, e.g. for lubricating a submersible pump.

In a method of pushing over a conveyer, consisting of pans 10 flexibly connected together, towards a coal face two abutment devices 12, 13 each capable of holding the conveyer 10 against longitudinal movement are used. Both devices 12, 13 are initially clamped, then a clamping ram 22 on device 13 is released and the conveyer section to the right of device 12 (as shown in the Figures) is pushed over by rams R1. Device 13 is then clamped and rams 15, 16 on device 12 released so that rams R2 are able to push over the gatehead unit G together with the device 12 which is then clamped. Any longitudinal movement of the conveyer away from a datum D is corrected by unclamping device 13 and using rams 17, on device 12, which act on the conveyer 10 through a clevis 18.

Reaction may be effected in an inert solvent over a wide temperature range in the presence of an acid acceptor, e.g. a tertiary amine.  The products obtained from a diacid halide may be cross-linked by heating above 50 DEG  C. and those from a carbonyl halide by heating with an alkali metal or its hydroxide, carbonate, alkoxide or aryloxide or a quaternary ammonium salt as catalyst.  The products may be used in coatings and impregnants for paper, textiles and leather; in paints, varnishes, adhesives and rubber; as moulding compounds with fillers, e.g. wood flour, cotton flock or glass fibres; and when thermoset as binders for sand, asbestos, silicon carbide or paper.  The products of the examples are soluble in methylene chloride and/or pyridine.

In the second form of bridge (Fig. 3, not shown) the two adjustable resistors R10, R20 are replaced by a single adjustable resistor in the form of a potentiometer, so as to provide adjustable areas (R110, R120), coils (104, 106) being arranged in series with the arms and being adapted to control a movable contact (112) which is thus caused to engage one or the other of two contacts (108, 110) connected respectively to windings (116, 120) of a reversible rotatable sermomotor for control of the burner, whereby rotation of the servomotor in one or the other direction is effected.
Patent GB-1080029-A (GB)
Title: Improvements in and relating to piezoelectric devices
Inventor: FOSTER NORMAN FRANCIS
IPC: H01L41/22
Filed: 1964-10-29
Abstract: A Piezo-electric transducer is made by evaporating a Piezo-electric semi-conductive substance on to a substrate and controlling the resistivity of the material during or after evaporation.  The method may be applied to cubic or hexagonal group II - VI compounds such as cadmium sulphide, zinc oxide, cadmium selenide, magnesium telluride or zinc sulphide.  The evaporation is carried out using known apparatus at a pressure of between 2 and 6 x 10-6 torr the substrate being held at a temperature such that a structure consisting of aligned crystals is built up (200-230 DEG C. is suitable for CdS). Thereafter, the temperature is raised to about 450 DEG C. to cause diffusion of compensating materials e.g. gold, silver, copper, from the substrate and/or an outer electrode whereby the resistivity of the layer is raised to at least 106O /cm. Alternatively, compensating material may be deposited along with the semi-conductive material. Other methods of compensation are also referred to.  The orientation of the Piezo-electric axis of the layer depends upon the substrate material. For longitudinal-mode operation, the axis must be approximately normal to the layer. This orientation is achieved by slow evaporation in a direction normal to a hot gold substrate.  For shear-mode operation an alignment parallel to the faces of the layer is produced by a relatively rapid evaporation at an acute angle on to a relatively cool substrate of silver.  A copper substrate may be used to obtain a mixture of both modes.  Copper, silver or gold may be deposited on a base of glass, quartz or aluminium and a nickel chromium alloy layer may be first deposited as a key.  The copper, silver or gold may also be deposited as an outer layer on the semi-conductive substance.
