Title: Arrangement for monitoring switch contacts closure sequence
IPC: H04B15/02
Filed: 1979-09-13
Abstract: The state of contact elements 10, 11, 12 is monitored by an arrangement such as Figure 1. Therein the contact elements are selectively connectible in bed pairs by means of a mechanical switch (not shown) - as, indicated by dotted lines, AND gates 20, 21, 22 corresponding to the possible connections. To determine which elements are paired, switch devices 16, 17, 18 are successively closed by pulses from a pulse generator 19. Thereby an interrogation potential V is sequentially applied to the contact elements 10, 11, 12. Consequently the AND gate corresponding to the operative pair is opened, a respective bistable circuit 26, 27, 28 is set, and a signal from a decoder 29 indicates the operative pair of contact elements. The application of the arrangement to the synchronizing of strokes or chimes to the hands of a clock, or setting to the correct time, is suggested. <IMAGE>

Title: Straight Pipe Coupling
IPC: F16L19/075
Filed: 1979-10-05
Abstract: A pipe coupling consists of male and female screw threaded members 2, 1 which bear upon two deformable ferrules 3, 4. A supporting sleeve 9 is also provided in the coupling assembly. When two pipes which require connecting are inserted into each end of the coupling their position is such that the sleeve 9 locates inside the pipes and the ferrules over the pipes. When the assembly is tightened by the outer members the ferrules are compressed onto the pipes. The coupling then provides a stiff, pressure tight joint which does not rely on the stiffness of the pipe to be coupled. <IMAGE>

Title: Quick-release drum-clamping device for stranding machines
IPC: B65H49/26
Filed: 1980-04-30
Abstract: In a quick-release drum-clamping device for stranding machines, a gear 7 fixed on the lower end of a hand lever 8 engages via teeth 6 a sleeve 3 which carries stub-shaft 4, which can move without rotation, and which is arranged in a lug 2 on a side of a yoke 1. A two-arm lever 12 is connected to a joint 9 in the sleeve and to a joint 11 of an adjustable connecting bar 10, which bar is connected by a joint 13 with a single-arm lever 17 connected by a joint 16 to stub-shaft 14. Lever movement thus moves the stub-shafts in opposite directions. The simultaneous stub-shaft movement takes place with a minimal effort by a single movement of the arm in the most ergonomically favourable position. <IMAGE>

Title: A Combustion Device
IPC: F23C10/00
Filed: 1980-06-11
Abstract: In a device for combustion having several combustion surfaces arranged one after the other in a direction along which fuel is conveyed and mounted so as to vibrate, drive arrangements 15 are controllable so that the direction of conveyance of the fuel may be changed as desired from a forward direction through zero to a rearward direction. The first combustion surface 2 has a greater inclination in the conveying direction than the following combustion surfaces 3,4, and a step 16 is provided between the surfaces 2 and 3.   The combustion surfaces preferably are in the form of smooth orificed plates, and have independent air supply arrangements 5,6,7. By controlling the speed at which the fuel is conveyed an optimum effect is achieved in the combustion process and it is possible to match the device to differing fuel qualities. <IMAGE>

Patent GB-802717-A (GB)
Abstract: 802,717. Electrostethographs. NATIONAL RESEARCH COUNCIL. Jan. 21, 1957 [Jan. 26, 1956], No. 2165/57. Class 81 (2). In electronic apparatus for observing heart sounds an additional amplifier is automatically switched in to provide higher gain at certain points. Thus if heart sounds of the form shown are received, the R waves 3 may be employed to control a known gating circuit to switch in a high-gain amplifier over the period 5, so that these murmurs may be observed. For this purpose the gain of this additional amplifier may be 100 times as great as that of the normal one through which the peaks 3 are received. In a modification it is proposed to control the switching of the high-gain amplifier by means of a wave received from an electrocardiogram.

Title: Bodyforms
IPC: A41H5/01
Filed: 1980-11-19
Abstract: A bodyform, in particular a dressform, has a central support (10) which carries opposed pairs of body sections (12, 13, 14) which are adjustable in spacing by means of adjustment mechanisms (16, 16A, 22) mounted on the central support. Each mechanism is operable by an operating rod (25) projecting from the bodyform which is rotatable about its axis to operate the adjustment mechanism and is axially displaceable to lock said mechanism in its adjusted position. A preferred adjustment mechanism comprises a pair of pushrods (16, 16A) which drive opposed pairs of body sections equally and oppositely, these pushrods being engaged with opposite sides of a central cog (22), thus enabling a driving gear (26) on the operating rod (25) to act on one of the pushrods (16) only. The adjustment mechanism is accommodated in a housing, which carries fixed teeth in spaced overlapping relationship to the teeth of the pushrod (16), whereby opposite axial movements of the operating rod (25) engage and disengage the driving gear (26) from the fixed teeth whilst such gear (26) remains in engagement with the pushrod (16). <IMAGE>

Title: Reducing gun erosion by transfer and diffusion coating
IPC: F42B5/24
Filed: 1981-02-02
Abstract: A method of reducing the erosion of surfaces of gun components on which there is flame impingement is provided. A thin coating containing metallic aluminium is applied to the surfaces, and is subsequently exposed to the hot compressed gases formed on firing. This causes diffusion of the aluminium into the surface, which reduces erosion. The coating may be applied either by the direct application of a paint containing metallic aluminium to the gun component then firing the gun, by applying such a paint to projectiles which are then fired from the gun, or by fitting a hollow frangible ring 1 containing a composition which includes metallic aluminium around the body of the projectile 2, and then firing the projectile. The coating may advantageously contain aluminium silicide. A number of paints and compositions suitable for the invention are described. <IMAGE>

Title: Safety device, having an automatic trigger mechanism, for use in electrical appliances
IPC: H01H37/76
Filed: 1982-04-26
Abstract: A safety device, e.g. in an electrical appliance for heating a liquid medium, is installed in the handle 2 of the appliance and constitutes an electrical switch 7 which comprises a bracing wire 6, a resilient electrical insulator member 10, a resilient electrical conductor member 9 and a gable-shaped spring 8. The bracing wire 6 is guided and releasably anchored in a tube 15 in a heating tube 3 of the appliance. The wire 6 extends into a meltable mass 12 in the bottom of tube 15 and an electrical heating coil 13. The free arm 17 of the spring 8 is coupled, in the closed position of the switch, to the free end of the insulator 10 adjacent the mounting of wire 6, which position is obtained by depressing a push button 11. When the appliance reaches a predetermined critical temperature, the melting mass 12 releases the bracing wire 6 which causes the switch 7 to open. On opening, the insulator member 10 is released by the spring 8 and the bracing wire is therefore allowed to return down the tube 15 and be re-anchored on cooling of the mass 12 thereby enabling re- closing by depression of a button 11. <IMAGE>
