Title: Improvements in or relating to the detachable coupling of vehicles
IPC: B60D1/26
Filed: 1934-12-11
Abstract: 448,866. Couplings for vehicles. KARRIER MOTORS SUCCESSORS, Ltd., AVERNS, R. DEAN-, and WHATMOUGH, J. E., Karrier Works, St. Thomas Road, Huddersfield. Dec. 11, 1934, No. 35510. [Class 103 (v)] Coupling means for tractortrailer combinations comprises at the rear end of the tractor, in association with each of the ramps b, a pivoted towing catch in the form of a two-armed lever d, d<1> connected by a link f, to a pivoted locking plate g, the link being provided with pins f<2>, f<3> which engage in angular slots h<1> in a pivotally mounted plate h connected to a spring j acting in tension on either side of the pivot g<1>. Prior to coupling, the spring j holds the parts in the position shown in Fig. 2 with the lower arm d of the towing catch raised so that it is engaged and pressed down as shown in Fig. 1 by the coupling cross-bar a, or a roller thereon, of the trailer, the cross-bar finally engaging resilient stops e carried by brackets e<1> with overhanging ends e<2> to prevent lifting. As the arm d is pressed down the other arm d<1> of the towing catch rises behind the crossbar, raising with it by means of the link f, the pivoted locking plate g, the end of which is shaped to conform to the back d<3> of the towing catch. At the same time the pins f<2>, f3 engaging the slot h<1> raise the plate h until the link i connecting it to the spring j passes the pivot g<1> whereon the tension of the spring completes the movement locking the towing catch in operative position. To release the coupling the locking plate g is pulled down by linkage g<3> including a lost motion connection, operated from the driver's seat. The Provisional Specification describes an arrangement wherein the spring j is connected to the locking plate g, omitting the plate h, and also an arrangement comprising towing catches pivoted to the ramps and held raised by springs, the trailer cross-bar riding over and depressing the catches which then rise behind them.

Title: Image pick-up devices
IPC: H04N9/04
Filed: 1975-08-29
Abstract: 1496920 Colour television WESTERN ELECTRIC CO Inc 29 Aug 1975 [3 Sept 1974] 35663/75 Heading H4F Colour television camera comprises a CCD image sensing array 21 associated with a colour coding filter 12. The CCD 20 shown is of the threephase frame transfer type with the electrodes connected to terminal A being reverse biased during odd fields and the electrodes connected to terminals B and C being reverse biased during even fields, an image resolution cell during the odd fields being shown at 31 (i.e. defined by three adjacent electrodes in each vertical column) and during even fields at 33 (i.e. centred over the space separating the electrode rows connected to terminals B and C, and thus cutting through two electrodes). The filter 12 includes a pair of areas, e.g. 13 and 14, defining a zone corresponding to each resolution cell, e.g. 31, and as shown in Fig. 2 these areas may have five different colour transmissivities designated J, K, L, M and N. Since every two vertically adjacent areas constitute a zone, the zones exhibit four different colour transmissivity characteristics K+J, L+J, M+J and N+J. The same line-sequential signals are produced in odd and even fields having the format K+J, L+J, K+J, L+J, ...and M+J, N+J, M+J, N+J, ... These signals are processed by adding and subtracting the dirct and one resolution cell horizontal scan period delayed signals to form the signals 2J+K+L (or 2J+M+N) i.e. luminance, and a line sequential colour signal K-L, M-N, respectively (Fig. 3, not shown). To ensure a correct luminance signal is derived K+L=M+N. In one example K = red, L = blue, M + red + blue, N = black and J = green, resulting in a luminance signal 2G+R+B and a linesequential colour signal R - B, R + B. A physical arrangement of a filter which provides the same characteristics as Fig. 2 is shown in Fig. 4 which includes only red, green and blue filter segments, the transmissivity of each area and zone being proportional to the weighted sum of the filter characteristics, i.e. J = 2/3G+1/3R, K = 2/3R+1/3B, L = 2/3G+1/3B, M = 2/3B+1/3R and N = 2/3G+1/3R.

Title: Hydraulic pressure reliev valve
IPC: F16K17/196
Filed: 1970-07-23
Abstract: 1315183 Hydrostatic transmission control ABEX CORP 23 July 1970 [6 Oct 1969] 35827/70 Heading F2D In an hydrostatic transmission comprising a reversible over-centre pump PV and a motor MF connected by delivery and return lines 2, 3, pressure relief is provided by a valve assembly 9 including a main poppet 39 seating against a surface 42 and controlled by a pilot valve 12 to interconnect ports 51, 52 connected to lines 2 and 3, respectively, when a predetermined pressure is exceeded in either line. The poppet 39 has a restricted orifice 44 in its lower end 41 to which the higher pressure from port 51 is fed directly or from port 52 is fed through the central bore 83 of a valve shuttle 69 moved up into contact with poppet 39 by the high pressure acting on a shoulder 76 adjacent the end of the shuttle. When the high pressure exceeds the predetermined value, it acts on the adjustable pilot valve 106 to relieve chamber 46 defined by the poppet 39, and the differential pressure acting across the orifice 44 opens the valve against the spring force 47 to interconnect the high and low pressure, ports 52, 51. The valve shuttle 69 serves also to connect a make-up pump PF via lines 130 and 126 to the port 51 or 52 at the lower pressure via a groove 128 in the shuttle. The central bore 83 in the shuttle is continuously in communication with the port 51 or 52 at the higher pressure and also communicates via a line 132 with a servo valve to control the pump displacement. Again, Fig. 2 (not shown), the pilot valve 211 is in axial alignment with the valve shuttle and poppet, and the motor outlet is connected via the valve assembly to a reservoir (RE) through a cooler (HE). To prevent the motor from driving the pump, the valve shuttle is spring-centred directing the motor exhaust to the pump inlet whereby the pump displacement controls the motor speed.
