Title: Optically readable record and reading apparatus
IPC: G11B7/24
Filed: 1979-03-30
Abstract: To allow closer spacing between tracks on an optically readable record in which each track has first areas 4 (or 4') - such as pits- and intermediate areas 3 (Figs. 1,3), at any portion on any track the areas 4 have a different phase depth to that of the areas 4' of the adjacent portion of the adjacent track. Within any track the areas 4 may all be of the same phase depth (Figs. 1 to 3) or the track may have regions a of a first phase depth alternating with regions b of a second phase depth (Figs. 4 to 6) - (eg. one horizontal video line per region). In reading apparatus (Figs. 8, 9), the outputs of two detectors 22, 23, one on each side of a line effectively transverse to the track direction 34, are added and subtracted for the larger and smaller phase depth regions respectively, changeover between addition and subtraction being effected by a switch 26, or 37, operated by a control signal Sc derived from a recorded pilot signal (audio record) or Sync. signals (video record). A track-following servo Sr directly or via an inverter 51 according to the position of a switch 52 operated by signal Sc. <IMAGE>

Title: Method of press forming sheet of inferior formability
IPC: B21D5/01
Filed: 1979-04-02
Abstract: To minimise temperature drop of a preheated blank (12) of inferior formability, such as titanium alloy, beryllium alloy or managing steel, during forming operation and thereby to relieve difficulty of press forming, at least one side of the blank (12) is covered with a layer (15) of a compressible heat-insulating material such as asbestos or ceramic fibre such that a punch (22) for press forming does not come into direct contact with the heated blank (12). The blank (12) and the heat-insulating layer (15) are preheated substantially to the same extent. Preferably the blank (12) is sandwiched between two plates (16, 18) of a metal having a better formability, and at least one side of the resultant lamination is covered with the heat- insulating layer (15). <IMAGE>

Patent GB-2062064-A (GB)
Title: Ditching Machine
IPC: E02F5/10
Filed: 1979-10-31
Abstract: A ditching machine for digging a ditch or a trench for submarine cables has several blades 51-57 disposed longitudinally along a centre body 2. The lower part of each blade serves as a digging portion which digs soil, and the wider upper part serves as a soil pushing portion which pushes away the soil thus dug substantially horizontally in a direction lateral to the moving direction of the ditching machine. The opposite ends of the soil pushing portions of the forward-most blades 51-56 are slanted to the vertical so as to slope outwardly in an upward direction so as to assist in pushing the excavated soil clear of the trench. In addition, the centre body has a plurality of small holes at the bottom to allow water to flow into the region at the rear of each blade, thus assisting in preventing the excavated soil from falling back into the trench and thus considerably reducing the towing tension in the towing wire between the ditching machine and the cable ship. <IMAGE>
Patent GB-2070121-A (GB)
Title: Mechanical Permutation Lock
IPC: E05B37/16
Filed: 1979-11-23
Abstract: A mechanical permutation lock is operated by a series of buttons 3, some or all of which must be depressed in the correct sequence. The right button pivots a lever which acts on lug 533 to move an element 53(a) of a two-part stop 53(a), 53(b). Each 53(a) operates a catch mechanism 54, 55 to free the adjacent 53(a), operated by the next button in sequence, from associated element 53(b). Depression of this next button then opens a gap through which tooth 66(a) of plate (62) may move. If a button is pressed out of sequence, then catch 54, 55 is not freed and part 53(b) moves with 53(a) to block plate 62. When the right buttons have been pressed, turning shaft 9 to move plate 62 is permitted and latch bolt 7 is withdrawn. Once the lock is opened, it is automatically reset. A change of combination of digitals can easily be manually effected without any tool. <IMAGE>

Patent GB-2041122-A (GB)
Title: Disc brakes
IPC: F16D55/2265
Filed: 1980-01-09
Abstract: A disc brake (1) comprises a piston and cylinder actuator (5,7) with cylinder (5) slidably mounted on a fixed carrier member (2) for movement parallel to the axis of rotation of the disc. The cylinder (5) is closed at the end adjacent the disc by an end wall 6. A U-shaped bridge member (10) is releasably secured to the piston (7). In use, when hydraulic fluid is supplied to the cylinder (5) the piston applies a force to pad (15) via the bridge member (10) and the reaction-force produced on cylinder (5) causes cylinder (5) to slide relative to carrier member (2) to apply pad (14). The seals (8, 9) between the piston (7) and cylinder (5) are isolated from the heat produced by the brake pads, and the bridge member (10) does not require accurate machining and can be designed to provide the maximum strength. Various pin sliding connections are disclosed for slidably mounting the cylinder (5) to the carrier member (2) (see Figs. 1, 3, 5). Anti-rattle springs (18, 19) are provided. <IMAGE>

Patent GB-2071827-A (GB)
Title: Improvements in or relating to air guns
IPC: F41B11/647
Filed: 1980-03-03
Abstract: A mechanism for an air gun uses carbon fibre reinforced composite material in the form of two arms stressed from a planar form to the bowed state, in which state considerable potential energy is stored, and held in this state by a sear (not shown) engaging piston a piston secured to the arms. In the embodiment of Fig. 8, a piston 2 is coupled to the ends of arms 6a, 6b through toggle linkages 5a, 5b through which arms energy is transmitted to the piston on release of the stressed arms to force same along the cylinder 1 communicating by orifice 3 with the gun barrel. The arms are stressed by first drawing back connection blocks 20 along guide 22 with attendant movement back of the arms and piston and thereafter forcing blocks 20, 22 forward whilst holding the piston to bow and stress the arms. The arms preferably are shaped in profile and section to impart a required force/distance characteristic to the piston. In an embodiment of Figure 5, arms 6a and 6b are coupled at their rear ends to blocks 7a, 7b pivoted at 8a, 8b. In operation a block 9, pivoted to the block 7a, 7b through links 10a, 10b, is moved rearwardly to allow the arms 6a and 6b to diverge. At this point the piston is restrained and the block moved forward to stress the arms to the bent position shown and secured against movement. Release of the piston causes it to move forward through the cylinder 1 under the force of the bent arms. <IMAGE>

Title: Thermal object coordinate determination
IPC: G01S3/784
Filed: 1980-04-18
Abstract: The positional accuracy obtained when observing an airspace over a wide angular range using a plurality of optical channels arranged at an angle relative to each other to determine the coordinates of a thermal object may be low because the individual channels are relatively large and hence limited in number. An arrangement is provided which comprises a number of optical channels, which scan adjacent solid angles and, via a moving modulation grating 3 which operates as a spatial filter, image each optical channel on a matrix 8 of IR detectors by means of an optical system 5, 6, 7. When an IR detector supplies a signal corresponding to a thermal object to be detected, the coordinate values of the thermal object relative to the relevant optical channel can be derived from the position of said IR detector within the matrix. When the individual IR detector signals are scanned by means of a multiplexer 13 controlled by a counter 14 the counter output 16 may directly represent the binary coded coordinate values. <IMAGE>

The channels 9 are fed from supply conduit 8 by inlets 10 flanking a rear wall-washing inlet 10A; the aperture 11 is fed via a hollow rim 6. The use of open channels 9, rather than an overhanging rim, facilitates manufacture by moulding. <IMAGE>
