Title: An arrangement for the indication of the type and speed of vehicles
IPC: G08G1/015
Filed: 1960-11-23
Abstract: 972, 775. Road traffic signals. TELE - FUNKEN A. G. Nov. 23, 1960 fNov. 25, 1959], No. 40283/60. Drawings to Specification. Heading G4Q. [Also in Division H4] A Doppler radar system for determining the lengths, in separate length categories, of vehicles passing through the lobe of the transmitter beam employs means for counting the passages through zero of the Doppler frequency which is produced by the passage of the vehicle. Based on the relationship that a vehicle of length a travelling through a transmitter aerial lobe of wavelength # and width b at an angle α to the horizontal produces a Doppler frequency oscillation train having 2(a +b)cos α/# cycles the Specification shows that practical measurements (with #= 3 cm. and α = 30 degrees) on a passenger car, a lorry and a lorry with trailer having respective lengths of 2, 5 and 11 metres give rise to (approximately) 300, 500 and 800 passages through zero of the Doppler frequency. Known electronic means may be employed for counting the zero passages and the results indicated by relay means individual to the three categories of vehicles. Alternatively, pulses derived by the passage through zero of each such cycle may be summed up in a Miller integrator circuit and the output signal which varies in the ratio 3: 5: 8 for the different categories, employed as an indication of length. The Specification describes, with reference to the accompanying drawing (not shown) a panel carrying indicating devices showing the number measured by the tuned reed method described in Specification 888,386 and speeds of vehicles in the different categories the response of an indicator being signalled to an operator by the lighting of signal lamps individual to each indicator, Photographic camera means may be employed for recording the indications.

Title: Improvements in or relating to the production of cyclohexanone oxime and caprolactam
IPC: C07D201/02
Filed: 1962-10-24
Abstract: Cyclohexanone oxime is produced by reacting an alkali salt of nitrocyclohexane with formic acid and an additional reducing agent, e.g. hydrogen sulphide, sulphur dioxide, hydroxylamine or zinc and dilute hydrochloric acid. The reaction may be effected in a solvent, e.g. cyclohexane, chloroform, carbon tetrachloride, paraffin hydrocarbons or an excess of formic acid. The product may be converted into caprolactam in known manner by the Beckmann rearrangement, or caprolactam may be obtained directly by effecting the reduction of the nitrocyclohexane salt in a medium which promotes the Beckmann rearrangement, e.g. sulphuric acid. Examples are given.

Abstract: 1374837 Making underwater connections SUBSEA EQUIPMENT ASSOCIATES Ltd 6 Sept 1972 [11 April 1972] 41307/72 Heading F2G A connection frame 20 carrying a conduit 33 and a guide structure 11 is connected by a locking head portion 22 to a device 3 on a baseplate 1 anchored to a submerged surface. As shown, the frame 20 carries the locking head 22 on a shaft 18 and is pulled by a cable 19 attached to a surface vessel which is also used in placing the baseplate 1 on a pile 2. Sections of the conduit 33 are assembled on the surface vessel and connected to a swivel joint 36 and elbow 35 in the frame 20. The frame is pulled into the receiving and attachment device 3. Radial blades 25 tear away any seaweed, etc. which may be caught on the locking head 22 as it enters the device 3. Further pull on the cable 19 causes a shear pin 16 connecting an inner sleeve 15 within a housing 12 to shear. The sleeve 15 slides to a stop member 17 withdrawing a keeper pin 14 to free a latch 13. The latch 13 is then urged by a spring 38 to drop behind a shoulder 32 on the head 22 to lock the head in the device 3 and hence to the baseplate 1. When the latch 13 falls a contact 39 closes to operate a signalling device 41. The end of the vertical section of pipe 33 is plugged with packing 8 and closed by a cap 9. These may be removed by a rod string and apparatus is then used to effect a connection with the conduit 33 to a further pipe (38) (Fig. 7 not shown, and Specification 1,374,838; see this Division).

Title: Method and Apparatus for Automatically Controlling Exposure Times in a Photographic Copying Machine
Inventor: THADDEY KURT
IPC: G03B27/80
Filed: 1967-09-12
Abstract: 1,195,545. Automatic colour printing control. CIBA Ltd. Sept.12, 1967 [Sept. 22, 1966], No. 41674/67. Heading G2A. Colour negatives to be printed in a copying machine, and which have a non-uniform distribution of brightness, are considered from two aspects: (a) the brightness of the upper and lower halves of the picture, as divided by a horizontal line through the centre, is compared, and a correcting or compensating signal applied to the exposure control means, (b) the brightness of a central singular area is compared with the brightness of the surrounding area, and a second correcting signal applied to the control means. Figs. 1 and 2 show the separate arrangements by which these two comparisons are assessed, and in practice are located one above the other. In Fig. 1, the particular frame 13 of the negative film 12 being copied is positioned above a ground glass screen 11 which provides a highly diffused uniform illumination from a source below it. A masking slide 14 has a window 15 such that it can expose either the upper or the lower half of frame 13, and is located in either of these positions by notches 16 or 17 which engage with a roller 18. At the same time it closes either switch 21 or 22, which is in series with a photo-electric device 19 inside a protecting hood 20. For an overall measurement the slide can be withdrawn completely. In Fig.2 the central area of the frame is defined by two L-shaped plates 26, 27 which are moved diagonally to vary the aperture between them. A slider 31 connected to plate 26 moves along a potentiometer 30, so that a sudden singularity will cause the signal to change abruptly, and also register its size. Fig.3 (not shown) is a block diagram of the electrical circuitry. Three separate measuring devices, all using the photo-electric element 19 in common, are provided for modifying the control (37) of the automatic exposure: one (33) for the overall brightness measurement for each colour component, one (39) for the brightness measurement of one half-picture against the other half (as in Fig.1), and one (40) for the measurement of the singularity area in the centre of the picture (as in Fig. 2). The signals from the two half-pictures Fig. 1 are stored in analogue storage devices (41, 42). They are then passed to a comparator (43) which compares and digitalizes them, and feeds them to digital storage devices (46, 47). They are compared to a range of reference levels, and if within this range, no correcting signal is sent to the control (37). If outside the range, a digital correction value is sent to the control. The size and brightness of the singular area measured by the Fig.2 arrangement determines the signal given out by its corresponding measuring device (40), which similarly is fed to comparators and digitalized. Again the measured brightness is compared with a reference range, and if outside the range a digital correcting signal is sent to the control (37).

Filed: 1975-10-11
Abstract: 1530298 Mattresses GELMAN HAWKSLEY Ltd 11 Oct 1975 41733/75 Heading A4M [Aslo in Division F2] A mattress unit for medical use comprises a flexible synthetic resin envelope 1 comprising two superimposed layers united around their peripheries and along lines defining two serpentine ducts 2,3 with respective inlet ports 2A,3A and outlet ports 2B, 3B releasably connectible to a hose assembly 4 connected to a control unit 5 controlling temperature and flow of water through the ducts. The control unit 5 comprises a switch operated pump 6, a reservoir 8 containing a thermostatically controlled heater 7, a valve 12 and a pivoted lever 11  movable to and fro by a selectively operated drive motor 9. In one mode of operation the lever 11 is swung to and fro about its pivot 11B by means of the drive motor which rotates a drive plate 9A carrying a pin 9B which is engaged in, and reciprocates along the length of, a slot 11A in the lever 11. The free and 11C of the lever 11 is disposed externally of the non-ferrous body of the valve 12 and its movement effects cyclic displacement of a valvemember 12A in the form of a magnet or magnetizable material between positions in which it closes one or other of two outlet ports 22,23 of the valve 12. The valve ports 22,23 communicate with the mattress inlet ports 2A,2B so that the displacement of the valve-member 12A allows circulation of water alternately through the ducts 2,3 to inhibit formation of decubitus ulcers on the user. The valve 12 has a single inlet duct 21. In another mode of operation the motor 9 is switched off whereby a microswitch operated by a formation on the plate 9A causes the lever 11 to stop in a position in which the valve-member 12A stops in a mid-position to open both valve outlet ports 22,23 and permit flow of water simultaneously through both ducts 2,3.

Abstract: 1523985 Electronic timepieces DAINI SEIKOSHA KK 11 Oct 1976 [13 Oct 1975]  42174/76 Heading G3T  An electric timepiece includes two numeric display units (e.g. liquid crystal devices) to display hours, two to display minutes and a further two display units which are used to display either seconds or date (day) (as illustrated) Fig. 4 (not shown), in dependence upon the position of a selector switch 9 (Fig. 1). In Fig. 1, a selecting circuit 13 selects the contents of seconds counter 4 for display on a device D when a control signal input thereto is logic "1", and selects the contents of the date counter 7 for display when the input is logic "O". The control signal to 13 is produced by logic circuits including NOR gates 1, 2 and flip-flop 12 in response to the state of switches 8 to 10. Switch 8 includes a safety lock circuit which must be in a released state giving a logic "1" output before a time-setting/ correcting switch circuit 10 can be effective. The manner in which switch circuit 10 effects correction is not described. Closure of a switch 11 opens an AND gate 3 to reset the seconds counter and display to zero, when the control signal to circuit 13 is logic "1". Operation of switch 9 triggers a flipflop 12 to select seconds or date display. In another embodiment Fig. 3 (not shown), the selecting circuit (131) includes transmission gates and the switching circuits 8, 10 control a ring counter (20) which controls logic gates.
