Title: Photographic slide mounts
IPC: G03B21/64
Filed: 1981-12-08
Abstract: A slide mount (1) for a photographic transparency comprises a main rectangular frame (3), and a retaining frame (2). The frames 2 and 3 each have a row of projections 7 and 8A which pass through the sprocket holes in the transparency and enter corresponding recesses 7a and 8. This results in the transparency being held under slight tension and prevents it buckling in alternative embodiments all the projections are formed on either frame 2 or frame 3. The frames 2 and 3 can have a co-operating sharp edge end groove which sever the transparency from a continuous strip when the frames 2, 3 are brought together. <IMAGE>

Title: Inlet-air conditioning for internal combustion engines
Inventor: SKEELS LOUIS REGINALD
IPC: F02M31/06
Filed: 1982-11-30
Abstract: A method of and apparatus for operating an internal combustion engine so as to condition the inlet air by mixing a main and a subsidiary stream of air, respectively at temperatures which differ by at least 20<o> C. This causes the formation of water droplets which are carried by the air into the engine with beneficial effects, inter alia reduced fuel consumption and pollutant emission and the ability to run on lower octane fuel. The subsidiary air stream is heated by exchange of heat with the exhause gases and is introduced into the air cleaner of the engine in opposition to the radially inward flow therein of main intake air so ensuring thorough mixing.

Patent GB-2147609-A (GB)
Title: Electrophoretic transfer
Inventor: SHUTTLEWORTH ANDREW D
IPC: C25B7/00
Filed: 1983-10-10
Abstract: Electrophoretic transfer apparatus has a support structure 32 pivotable about a horizontal axis in a buffer chamber. To transfer, for example, proteins or nucleic acids from a gel (where they have been separated by electrophoresis to a nitro-cellulose sheet, a suitable stack is formed on the horizontal support, under the surface of the buffer liquid. The support is then pivoted to the vertical position for electrophoretic transfer. Since the stack is formed under buffer, the problem of air entrapment between the layers is much reduced. The application also relates to electrophoretic transfer apparatus comprising a chamber for containing buffer liquid, a pair of electrodes 14, support means 24 for supporting sheet-like media for electrophoretic transfer, and guide means 12 extending transversely of the chamber, at least one of the electrodes being in sliding engagement with the guide means to vary the inter-electrode spacing. <IMAGE>
Patent GB-2148189-A (GB)
Title: Production of dry transfer word sets
Inventor: JUNG NICHOLAS ROBERT
IPC: B41M3/12
Filed: 1983-10-18
Abstract: Dry transfer word sets are produced using a tape comprising a flexible backing tape (1) and a translucent or transparent carrier tape (4) having therebetween a shearable dyed or pigmented layer (2). When raised characters (6) are successively pressed against the tape, the adhesion of the shearable layer material to the carrier tape (4) increases where the pressure is applied. Thus when the backing and carrier tapes are separated in the areas against which the raised characters (6) have been pressed, the shearable layer material is retained on the carrier tape (4), while the remaining shearable layer material is retained on the backing tape (1). The shearable layer material is transferred from the carrier sheet (4) on to a receptor surface (5) by rubbing on the rear of the carrier tape (4). <IMAGE>

Patent GB-2139441-A (GB)
Title: Circuit and method for reducing non-linearity in analog output current due to waste current switching
Inventor: WANG ANTHONY D
IPC: H03M1/06
Filed: 1984-01-27
Abstract: An integrated circuit digital to analog converter using a R/2R resistor ladder has, in a typical bit stage, a bit current transistor (eg 60-1), and a waste current transistor (eg 61-1) connected as shown, with the collector of the latter connected to a metal ground voltage conductor (41) at a "shared node" also connected to the ladder rung resistor. The waste current transistor switches waste current into the shared node, rather than into a separate waste current ground conductor. This results in substantially less voltage variation across the distributed resistance of the metal ground voltage conductor, and consequently lower non-linearity. Most- significant bits may use binary-weighted constant-current sources, rather than the ladder. <IMAGE>

Title: Target homing system
Inventor: BLAKE ASHLEY KENNETH
IPC: F41G7/22
Filed: 1984-10-15
Abstract: A homing system, e.g. on board a guided missile or bomb, for tracking an R.F. emissive target such as a radar transmitter comprises an interferometric receiver with a pair of spaced antenna elements 1, 2, mixers 3, 4 for down-converting the R.F. signals to form respective constant frequency I.F. signals, which are compared by phase comparator 7 to form a direction-of-arrival signal. As the target moves relative to the system, the direction-of-arrival signal goes through a series of null values. The system therefore includes sensor means 9, 10 for sensing null crossings of the direction-of-arrival signal which allows ambiguity problems to be obviated. <IMAGE>

Title: Blind fastener
Inventor: JEAL HARVEY PHILIP
IPC: F16B19/10
Filed: 1985-11-28
Abstract: In a blind fastener which is set by expanding the leading end 62 of a sleeve 16 by forcing it over a tapered nose 22 as the bolt 14 is screwed into the tubular nut 12, the leading end 62 is formed with a greater internal diameter and a lesser wall thickness than the rest of the sleeve 16. The nose 22 is shaped to engage the thicker-walled part 70 of the sleeve 16 and expand it to a diameter greater than that of the shank 18 without engaging the thin-walled portion 62, so as to cause the thin-walled portion 62 to be reorientated to form an annular disc 72. The clamping force is applied mostly to a region of the workpiece surface 52 spaced from the hole 44, and is distributed over an area greater than the cross-sectional area of the thick-walled portion 70 of the sleeve 16. <IMAGE>
Patent GB-2170969-A (GB)
Title: Electrical filter
Inventor: HUGHES JOHN BARRY
IPC: H03H11/00
Filed: 1985-11-29
Abstract: A continuous time electrical filter fabricated as an integrated circuit includes capacitors (CO,CN) and resistors (R1,R2). Since capacitors and resistors are difficult to integrate with accurately defined values a trimming circuit is provided which operates switches (S1-SN) to select appropriate ones of the capacitors (CN) to accurately define the cut-off frequency of the filter. The trimming circuit comprises a capacitor (TC2) which is charged through a resistor TR1 during a first period and which is discharged in incremental steps by capacitor (TC1). The number of incremental steps is counted by a counter (11) and transferred to a register (13). The outputs (S1-SN) of the register (13) control the switches (S1-SN). Instead of adjusting the value of the capacitors in the filter the values of the resistors may be adjusted. If this is done a convenient procedure is to short out selected portions of the resistors. More than one capacitor or resistor may be adjusted using a single counter and register. <IMAGE>

The slider guide member comprises a strip of sheet material having an elongate guide portion (29) extending from an upstream side of the recessed discharge roller (22) toward the downstream side of the latter along the periphery of the annular recessed portion (27) in confronting relation to the other discharge roller (21). With the slider guide member thus provided, the slide fasteners can be discharged smoothly from the apparatus without the occurrence of deformation of the sliders and their pull tabs. <IMAGE>
Patent GB-2190803-A (GB)
Title: Light-dependent timer switching system
Inventor: ONG YONG KIN MICHAEL
IPC: H05B37/02
Filed: 1986-05-20
Abstract: When a low ambient light level (dusk) is detected by a sensor 30, a flip-flop 32 is caused to send a high signal to a switch 41 and a low signal to an inverter 33. A load 42 is thereby turned on and an inverter 36 supplying a low signal to an oscillator/timer 37 which is thus started and has its output set low whereby, via a flip-flop reset circuit 39, the flip-flop 32 is latched to prevent an erroneous turn off of the load 42 caused by light therefrom possibly being received, after reflection, by sensor 30. When timer 37 times out, the load 42 is turned off, flip-flop 32 is reset, and the circuit operates to prevent load 42 being erroneously turned on again should the light received by sensor 30 fall as the load was switched off. The system is reset at dawn in readiness for the next switch-on cycle. The load may be an incandescent or fluorescent lamp, a radio or T.V. set, or hi-fi equipment, and the circuitry may be incorporated into an adaptor (47) to fit a lampholder, or into a fluorescent lamp (46), (Fig. 4). <IMAGE>
