Abstract: 1439038 Steering motor vehicles; rudders K H THOMAS [trading as LANGEN & CO] 14 Aug 1973 [26 Aug 1972] 38466/73 Headings B7H and B7V In a power assisted control unit of the type used for steering vehicles or turning ships' rudders and comprising a power output member 3 connected to an input member 1 through elastic means 2 and also connected to an hydraulic servomotor 9 controlled by a valve 13<SP>1</SP> which is operated in response to relative movement between the input and output members and either has reaction surfaces a subjected to the pressures in the respective chambers 10, 11 of the servomotor 9 or has associated therewith one or more separate reaction members, the valve 13<SP>1</SP> is actuated by the input member 1 through a lost motion coupling 24 and is of the closed centre type. If the input member 1 is actuated and the output member 3 moved thereby without the elastic means 2 being deflected sufficiently to take up the lost motion at the coupling 24, movement of the servomotor piston 7 with the output member causes in one of the chambers 10, 11 of the servomotor an increase in pressure which is communicated to one of the reaction surfaces a to displace the valve 13<SP>1</SP> and allow unhampered movement of the piston. The elastic means 2 may be pre-loaded, and further elastic means having a lower pre-load may be connected in parallel with the lost motion coupling 24. Both elastic means may have a linear or a non- linear characteristic. The servomotor may have a "differential area" piston with the valve exercising "two-edge" control. In Figs. 5, 6, a power steering control valve 37 includes a mounting unit 38 containing a power output member in the form of a valve body 47. Transverse bores 48, 49 in the body 47 contain a control piston 50 and a reaction piston 53 which have respective reaction surfaces a, b and are actuated through tappets 54, 55 by a lever 56 pivotally supported on a knife edge 57. An input shaft 6 rotatably mounted in the valve body 47 and coupled thereto by a torsion bar 62 carries a lever 60 which acts on the lever 56 through springs 58, 59 and is allowed a degree of lost motion before coming into mechanical contact with the lever 56. In another embodiment, Figs. 7 to 10 (not shown), the input shaft and the valve body are resiliently coupled by a pre-loaded C-spring surrounding the valve body instead of by a torsion bar, and in Fig. 11 (not shown) the lever on the input shaft is in the form of a leaf spring.

Title: Means for connecting a flat-roof wall connection strip to a wall
IPC: E04D13/14
Filed: 1977-09-19
Abstract: The device is constructed such that, on the wall, the upper longitudinal side of the flashing piece is guided in a wall connecting rail (1) which is let into the wall (3) or is fitted thereon. In order to simplify mounting of a device of this type and, in addition, to ensure satisfactory sealing, there is provided a profiled strip (7) which consists of an elastomer or a plastomer and has a nose (8) which can latch into the inwardly bent end (6) of the wall connecting rail (1). In this arrangement, it is preferred that, in the profile, the strip (7) has a lip (9) for connection to the flashing piece (4). Advantageously, the device can thus also be used readily for flashing pieces of relatively low thickness. <IMAGE>

Title: Improvements in or relating to a temperature indicating device for use with rotating heated rolls
Inventor: HALL DONALD WILLIAM
IPC: G05D23/24
Filed: 1965-09-13
Abstract: 1,135,397. Automatic temperature control. FIELDEN ELECTRONICS Ltd. Sept.9, 1966 [Sept.13, 1965], No.38969/65. Heading G3R. [Also in Division G1] The temperature of a heated roller is measured by a temperature-sensitive resistor connected in a bridge circuit, the apparatus being arranged for rotation with the roller. The bridge is balanced at a pre-selected temperature, and any divergence is shown by a lamp, and is used to control the roller heater. As shown Fig.2, a temperaturesensitive resistor 7, mounted in the surface of a roller to be heated, is connected in a normally balanced bridge circuit fed by a transformer 1 connected to an A.C. supply via slip rings 2. Any output from the bridge is fed via a potentiometer 15 to transistor 24, normally biased to saturation conduction. When the output signal exceeds a threshold value the transistor collector current is reduced, and the voltage rise at the collector causes diode 31 to conduct current to the gate circuit of a thyristor 16, which fires to light a lamp 17 in a self-holding circuit. The output from the bridge is also used to control a heater 13 for the roller. The temperature deviation signal is amplified at transistor 8 and fed to a phase detector transistor 9, whose collector is connected to the A.C. supply via a diode 48. The mean D.C. potential at the collector of transistor 9 is smoothed at 50, 51, 52 and fed via a pulse transformer 54 to transistor 10 with a feedback winding in the emitter circuit. Transistor 10 produces pulses in the transformer 54 at a frequency determined by the base drive potential, which is itself determined by the phase sense and amplitude of the bridge output signal. Transformer windings 60, 61 supply gating pulses to reverse-connected thyristors 11, 12 so that heater 13 carries current for controlled periods of each half cycle, thereby maintaining the roller at a predetermined temperature.

Abstract: 881,765. Flaw detection apparatus. GENERAL ELECTRIC CO. Ltd. Dec. 3, 1959 [Dec. 3, 1958], No. 39005/58. Class 40(3). An apparatus for the detection of cracks in the surfaces of glass bodies comprises means for holding the body stationary in an examining position, means for directing light on to a part of the surface whilst the body is so supported, detecting means including a photocell for receiving light from or through the surface, and means for moving at least part of the detecting means relative to the surface, the photocell output being used to operate indicating means if a crack is present in the surface. For the inspection of the necks of bottles, which may be mounted on a conveyer, a cage 6 is lowered over the bottle neck 15 and light from a lamp 10 directed via mirrors 12, 13, 14 on to the neck 15. A mirror 16, shown for convenience opposite to mirror 14 but in practice displaced by about 30 degrees from it, receives the reflected light and passes it to a photocell 20 which is shielded from light direct from lamp 10 by shield 22. By rotating, and if necessary lowering, the cage 6 with the mirrors and shield the whole of the bottle neck is inspected. The photocell output is used to control an indicator which may form part of a rejection device.

Abstract: 892,502. Electric lamp combined with reflectors. LIBERMAN, M., and LIBERMAN, R. Nov. 15, 1960, No. 39131/60. Classes 39(2), 75(2) and 75(4). An incandescent electric filament lamp having a glass envelope is fitted with an external reflector of thin material which is in substantially unrestricted spaced relationship with the lamp envelope so as to form an annular air passage, part at least of the heat emitted by the filament being intercepted and reflected by the reflector to raise the temperature of the envelope above that of an unenclosed bulb. Preferably the material is of a thickness less than 0À02 inch. In the form shown, the upper part 20 of the reflector follows the contour of the bulbous part 12 of the lamp, the lower part 21 being, for example, parabolic. The reflector is supported by spacers 23 secured to the upper edge of the reflector and shaped like a V with a flattened apex 25 which is cemented to the bulb. A stem 14 within the bulb may carry a curved reflector 16. In a modification, the spacers are formed by elongated tabs extending downwards from the periphery of the reflector, the ends of which are turned at right angles and the edges cemented to the bulb. In a further modification, tabs 51, Fig. 9, are punched out of the surface of the reflector 50 leaving openings 53 which serve as air vents, the free edges of the tabs being cemented to the bulb 30 to form spacers. The inner surface of the reflector may be covered by a pattern of ribs 54, or may be anodized in any colour and used with clear or tinted lamps. An openwork grill of thin metal, glass or plastic may be supported on the mouth of the reflector.

A machine for making hinges comprising two perforated plates and interposed offset ribs connected by an axis pin comprises a support base 20 having a table-like part 21, two slidable electrically driven drills 22 facing one another, a stop 29 for locating the interengaged hinge parts 25, 26, and a holding plunger 31, means for advancing the drills towards each other for drilling the ribs, means for retracting one drill and advancing the other to complete the drilling, means for holding the drilled parts together and forcibly inserting an axis pin 38 and means for simultaneously drilling a number of holes for wood screws in the halves of the completed hinge. The interengaged hinge halves are clamped between members 29, 30 and the drills advanced via guides 33 to drill the axis pin hole, one of the drills being subsequently retracted and the other advanced to complete the hole. The drilled and assembled halves are next manually transferred, clamped by plunger 34 and a manually located pin forcibly inserted in the hole by a plunger 36. Subsequently the assembly is manually placed on an inclined slide 39 where it gravitates against a stop under a multiple drill head unit 40, e.g. of four, six or eight drills, which drills and countersinks woodscrew receiving holes therein. Finally, the assembly gravitates down a further slide 41 to a H-shaped slot 43 and is depressed with the slide by a plunger 44 to carry the assembly over a pair of grinding discs 45 which grind the ends and pin flush. Upon release the assembly gravitates to a further stop 47 and is partially closed by a plunger 48 which on retraction allows the hinge to fall through a slot 46 to a discharge ramp 49. A hinged extension 42 prevents an assembly from passing from the slide 39 to the slide 41 when the latter is depressed. The assemblies are fed one-by-one through the machine. Pneumatic means and micro-switches are used to operate and sequence control the machine.
