Patent GB-2039264-A (GB)
Title: Security Cassettes
IPC: G07D11/00
Filed: 1979-11-29
Abstract: A cassette has a shutter 12 which in a first position, obstructs an aperture and a mechanism which moves the shutter 12 from the first position to a second position when actuated by an external actuator 30 engaging lugs 29. When the external actuator 30 is removed the mechanism automatically returns the shutter to the first position, in which it is locked by a catching mechanism, figure 5 (not shown) unless released using key (57). The cassette contains a stack S of sheets, such as bank notes, which are manually loaded through a pivoted lid 6 and retained by a pressure plate 38, a pivoted bridge piece 31 preventing the lid 6 from being opened when the shutter 12 is closed. A coloured indicator is visible through a window (59, figure 1, not shown) to denote the condition of the latching mechanism. <IMAGE>

Title: Power supply for electric cooker
IPC: F24C7/08
Filed: 1980-01-15
Abstract: In order to limit the disturbance to the mains supply caused by periodic energisation and deenergisation of a resistive load such as the heater of the grill of an electric cooker, the heater is split into two heating elements which are energised alternately each for a period of time set by a user operable control 2. The mark to space ratio of the energisation of the partial loads 1a and 1b is varied in dependence upon the setting of the control 2. In order to provide fast response when the apparatus is first turned on, circuitry 16 overrides the proportion of control and energises both loads 1a and 1b simultaneously for a predetermined period of time long enough to bring the heater up to its working temperature. <IMAGE>

Title: Steplessly adjustable belt transmission
IPC: F16H55/56
Filed: 1980-04-09
Abstract: The driving pulley 4 has an adjustable half 10 actuated hydraulically or mechanically. The driven pulley 8 has a self-adjusting half 18 biased by a spring 22.

Title: Inspection machine
IPC: B66F11/04
Filed: 1981-01-12
Abstract: A bogied railway vehicle 1 carries an inspection machine for both overhead inspection work and inspection of the underside of viaducts. The machine comprises two hinged booms 4 and 6, the former being pivoted at horizontal axis H1 to a turntable 3 which is rotateable about a vertical axis V2 on a horizontal slewing arm 2. An inspection platform 8 is carried by a telescopic section 7 of the boom 6. A cam and switch arrangement, responsive to the relative orientations of boom 4 and each of turntable 3 and boom 6, restricts movement of the booms to within a safe working envelope, while a rotary arrangement provided on the arm 2 prevents the turntable 3 from assuming certain orientations for particular angular positions of the arm 2 relative to the vehicle 1. Each bogie of the vehicle 1 may have one or more jacks 42 for transferring load directly to the rails rather than through the bogie side plates 48 and suspension 49. The machine may be stowed for transport with the arm 2 along the longitudinal axis of the vehicle 1 and the booms 4 and 6 closely adjacent and horizontal. Pin of pivot 18 may be removed so that knuckle joint 15 is stowed at a low level. <IMAGE>

Patent GB-2082601-A (GB)
Title: Polymerization process
IPC: C08J3/12
Filed: 1981-08-17
Abstract: Polymers are prepared by free- radical polymerization of one or more ethylenically unsaturated monomers in an organic solvent in the presence of a polymeric stabilizer which is an alkylene oxide adduct of a styrene-allyl alcohol copolymer. The organic solvent can be an optionally unsaturated polyol in which case graft polymer dispersions in a polyol are produced. Alternatively, other organic solvents can be used and finely divided polymeric solids obtained which may subsequently be dispersed in a polyol. The resulting dispersions in either case may be used in the manufacture of polyurethane foams.

Title: Gun fire control systems
IPC: F41G3/08
Filed: 1982-02-24
Abstract: A gun fire control system comprises a first memory (15A) operable on receipt of a true range value from a rangefinder (16) to output the corresponding standard ballistic range value. A second memory (15B) is pre-programmed with correction coefficients (A, B, M, N) delivered to a calculator (15C) together with an operator correction value (COR) (from buttons 14A, 14B). Calculator (15C) operates to establish air density and charge temperature parameter correction changes ( DELTA  AD,  DELTA  CT) and delivers these changes to calculator/store (15D) which updates and stores parameter values (AD, CT). An arithmetic unit (15F) evaluates a range correction factor from the data available from memory (15B) and unit (15D) at the ballistic range established by memory (15A). This range correction factor is combined with the ballistic range established by memory (15A) in unit (15G) and the corrected ballistic range made visibly available in display (11) to the operator. <IMAGE>

Title: Elastomeric knitted pile fabrics
Inventor: HORSFALL DR GEOFFREY ALAN
IPC: D04B21/04
Filed: 1982-03-01
Abstract: A method for producing a warp or weft knitted fabric on a knitting machine, the fabric having a first, elastomeric fibrous component, a second, non-elastomeric, fibrous component and optionally a third or more, non-elastomeric, fibrous components characterised in that at least part of the second fibrous component is knitted into the fabric with a long float such that when the fabric is removed from the knitting machine, the elastomeric first component contracts such that the long floats of the non-elastomeric second component are forced into free standing loops to provide a loop pile on the fabric. Desirably the free standing loops are cropped to produce a pile fabric in which the second fibrous component is in essentially discontinuous lengths, each of which is in general associated with one stitch only.

Abstract: Bending apparatus for rattan stems comprising a mounting table (5) with a cylinder (S), guide sheaves (1<u1>u-1<u4>u) mounted on an extension of the shafts of respective rotary actuators (M<u1>u-M<u4>u), and bending sheaves (2<u1>u-2<u2>u and 3<u1>u-3<u2>u) mounted on arms of the respective rotary actuators (M<u1>u-M<u4>u) which are adjustable radially with respect to the respective axes of the rotary actuators (M<u1>u-M<u4>u) and which may be replaced by sheaves having other contours and diameters, or by contour templates if the blank (9) is to be given a special configuration. The hydraulic rotary actuators (M<u1>u-M<u4>u) can be driven in both directions of rotation, are adjustable in all planes, and can be rotated 160`. Mounted on the table (5) is abutment means (8) which provides the correct surface of abutment for the rattan bent by the apparatus.

The attachment means (6) for the hydraulic rotary actuators (M<u1>u-M<u4>u), mounted on the table (5), permits these to be adjustable in all planes. The bending apparatus also comprises a jig which is made of a rigid material and has "ears", brackets and offsets attached thereto, such that it can be fitted down over the blank while the latter lies clamped in the bending apparatus to lock the blank in the shape it has assumed in the apparatus.

Title: Frequency synthesiser
Inventor: RICHARDSON CHRISTOPHER KEITH
IPC: H03L7/187
Filed: 1982-07-10
Abstract: A digital frequency synthesiser comprising a voltage controlled oscillator (VCO) providing an output signal, the VCO frequency being controlled in dependence upon a control signal produced by a frequency comparator (5) in the presence of frequency difference between a reference frequency signal (6) and a signal derived from the VCO via a variable divider (4). The frequency comparator is coupled, upon operation of switch means (9, 10), via a selected one of a plurality of sample and hold analogue stores (8) to the VCO, so that the control signal updates a voltage stored in the selected sample and hold analogue store, the stored voltage being used to control the frequency of the VCO, the switch means being operated for selection purposes in accordance with the setting of the variable divider as determined by a programme stored in a read-only memory (ROM) means so that for a given setting, a predetermined sample and hold analogue store is selected contemporaneously with the setting of the variable divider, the ROM means being responsive to a clock signal derived from the variable divider for changing repeatedly in steps the setting of the variable divider and thus the frequency of the output signal. The output frequency of the synthesiser may thus be rapidly "hopped". <IMAGE>
