Title: Pre-set dimmer switch
Inventor: SPENCER VICTOR JOHN
IPC: H05B39/02
Filed: 1982-10-14
Abstract: Most dimmer switches available incorporate a Triac, or similar control arrangement for continuously adjusting the light level. However, in many domestic applications, such a switch is unnecessarily expensive, and indeed not precise, particularly where two or more pre-set levels of lighting may be required. In a relatively inexpensive dimmer switch at least one capacitor 1 can be switched into series with the mains 2, the value of the capacitor being selected in dependence upon the recommended wattage of the lamp 3 it is to control, to produce a required level of dim illumination. Preferably, the circuit provides for more than one pre-set dim level of illumination or more than one lamp wattage by incorporating a number of capacitors and a combination of series/parallel switch connections (6, Figure 2). A resistor 5 discharges the capacitor 1 when the circuit is disconnected from the mains. Alternatively, the selector switch 4 may be arranged to short out the capacitor in its "OFF" position. A neon 7 indicates the dim setting of the switch 4. <IMAGE>

Title: Propellant Compositions
Inventor: SPICKERNELL GRAHAM JAMES
IPC: C06B21/00
Filed: 1983-05-26
Abstract: This invention relates to the manufacture of composite propellants containing rubbery binders and particulate non-binder ingredients. The process consists of curing a mixture of a functionally-terminated hydro-carbon prepolymer and a cross-linking agent to form a viscoelastic first binder composition, mixing the binder with non-binder ingredients to form a plastic propellant, and rubberising at least a part of the plastic propellant by adding to it a further quantity of the cross-linking agent, provided the propellant is formed into a propellant charge while still in a plastic state. The further quantity of the cross-linking agent may be mixed in with the plastic propellant prior to forming, or applied to the surface of the plastic propellant after having been formed into a charge. In a preferred embodiment of the invention, the prepolymer consists of an hydroxy-terminated polybutadiene having a molecular weight of about 3000 and a functionally of about 2.2, and the cross-linking agent consists of isophorone diisocyanate.

Title: Encapsulating flowable materials
Inventor: LUXMOORE ROBIN JOHN
IPC: B29C48/09
Filed: 1984-02-01
Abstract: A hollow mandrel 2 cooperates with a die orifice 7 and is axially displaceable, between retracted and advanced positions relative to the die orifice, to effect alternate extrusion of solid sections and tubular sections of aluminum, copper, or plastics. During extrusion of the tubular sections with the mandrel 2 advanced, a flowable feed material is introduced from a hopper 1 through the mandrel and is encapsulated within the extrudable material. The encapsulated material may be radioactive or toxic, and a mandrel which is thereby contaminated may be allowed to fall through the die orifice and itself become encapsulated in the extrudable material, and a replacement mandrel can be inserted into the die head from the exterior. <IMAGE>

Title: Circular knitting machine
Inventor: DYNTAR MILOS
IPC: D04B15/24
Filed: 1984-07-25
Abstract: A circular knitting machine for the production of hosiery and the like goods both in rotary and in reciprocatory knitting, is provided with a sinker ring cover with cams (8, 9) to control the knock over sinkers which co-operate with the needles being controlled by a cam system with at least one knitting feed with a left and a right stitch cam (1,2 or 4,5) for reciprocatory knitting. This invention solves the problem of guiding the knock over sinkers for rotary and reciprocatory run by arranging that the sinker ring cover is swingable within the angle between the knock over points of the left and the right stitch cams (1,2 or 4,5) in a knitting feed so that the active section of the cams (8,9) is aligned with the left stitch cam (1,4) for knitting direction S and with the right stitch cam (2,5) for the opposite knitting direction. The sinker ring cover is entrained by friction and arrested by stop means (13, 100, 101). <IMAGE>

Title: Method and apparatus for hydrodynamic magnetic recording
Inventor: BARDOS ANDREW M
IPC: G11B5/60
Filed: 1984-08-02
Abstract: Problems of wear and bounce created by inperfections in the surface (12) of a magnetic recording medium, such as a chromium dioxide-coated drum (10), are circumvented by a hydrodynamic magnetographic imaging technique that provides the intended effective intimate contact between the recording head (14) and the magnetographic recording surface (12). A liquid (e.g. water) (51) is applied to the surface of the drum (10) slightly upstream of the location of the recording head (14), so as to create a liquid bearing (51) against which the recording head (14) is urged, and thereby intimately magnetically coupled with the surface of the drum, except for an extremely thin liquid film (51) between the head (14) and drum surface (12). As a result of this extremely thin liquid bearing (51), continuous pressure can be applied to the head (14) to maintain the head (14) in effective intimate contact with the surface (12) of the recording medium without the fear of scratching the medium or causing wear on the head (14).

Inventor: JOHNSON JAMES FREDERICK JOHN
IPC: B23P6/00
Filed: 1985-07-10
Abstract: An old taper bore racking bung 2 of a barrel 1 is removed, and replaced by a new threaded racking bung. A pilot hole 5 is drilled through the wall 3 of the barrel diametrically opposite to the existing racking bung 2, and is utilised as a centre location for cutting a circular hole 9 of adequate diameter to provide clearance for rotary cutter means 13. The means 13 are used to cut out the internal weld of the existing racking bung 2, and the external weld thereof is cut out separately. The new racking bung is fitted utilising the circular hole to provide access for a rotary welding head which is used to produce the internal weld of the new racking bung, and the circular hole 9 is subsequently closed by welding a closure plate 21 into the hole. <IMAGE>

Title: TDM switching system
Inventor: SCARR ROBERT WALTER ALISTER
IPC: H04Q11/04
Filed: 1985-08-17
Abstract: A TDM switching system of the TSTST type uses modular terminals, and control is substantially decentralised. For signalling, the messages are sent ahead of the data, etc. to which they relate, and each such message identifies its source in the first T stage by the time slot in which it occurs. Each such message includes the address of the destination portion of the last stage and is broadcast to all parts of the last stage. The system may use a ring (or bus) of the area network type, in which case the network acts in effect as the central T section. <IMAGE>
