Title: Improvements in or relating to Spigot Joints for Tubular Structures
Inventor: BARNHAM JOHN WILLIAM
IPC: E04G7/30
Filed: 1966-11-14
Abstract: 1,150,359. Releasable spigot and socket joint. ACCESS EQUIPMENT Ltd. 17 Oct., 1967 [14 Nov., 1966], No. 50907/66. Heading F2G. [Also in Division E2] A spigot joint for use in tubular structures includes a spring-pressed locking-pin e mounted in a spigot member c carried by a tubular component a and adapted to be automatically interlocked in a socket member d carried by another tubular component b, a manually operable device being provided to lock the spring and locking pin in an inoperative position to permit disengagement of the parts. The socket member b has a ring d provided with an inclined surface p which, as the socket is moved on to the spigot, depresses the stud k and pin e in turn until, at the completion of engagement shown in Fig. 3 the stud and pin are moved outwardly by the slotted leaf-spring g into a keyhole opening o in the socket. To release the parts the stud is pressed in and moved upwardly along the spring until the shoulder n of the stud engages the top edge of slot l in the spigot, the spring g and pin e thus being held out of engagement with the socket, as shown in Fig. 4, to permit disengagement of the parts.

Title: Decoder matrices
IPC: H03M7/00
Filed: 1963-12-24
Abstract: 1,074,455. Data stores : digital conversions. RADIO CORPORATION OF AMERICA. Dec. 24, 1963 [Jan. 10, 1963], No. 50981/63. Headings G4C and G4H. [Also in Division H3] A decoder matrix comprises n groups of m output rows each, n first switching means, each of which when closed applies a drive current to all rows of a respective group, and m second switching means each connected to one row of each group through respective uni-directionally conducting elements and, when closed, providing a low impedance path for drive current appearing on rows to which it is connected. In Fig. 1, one of nine rows 71 . . . 79 of a core memory 80 is selected in a row decoder Y by closing one of three switches 41, 42, 43 thus passing current to three of the rows 71 . . . 79, and by opening one of three switches 45, 46, 47 the other two providing low impedance by-pass paths for current sent to two of the selected three rows. Thus only one row actually passes current into the memory 80. A column decoder X selects one column of the memory 80 in a similar manner. Each core of the memory 80 is shown with one winding (in series with a diode 87) but each core actually has two, extra row and column decoders like X and Y being provided. All the switches shown are transistors. Figs. 4, 5 (not shown) show a 9 x 9 memory matrix of ferrite cores each with two windings (one for reading and one for writing) in series with diodes but only one pair of row and column decoders is used (the column decoder being double-size however). In order to provide the additional selection of read or write winding, the column decoder has six (rather than three) triads of leads (like 71 . . . 79 of Fig. 1) and each of three switches (C1 . . . C3) is connected to two triads (not one) via respective pairs of coupled windings (299, 230 &c.) one pair being selected to act like a transformer to pass a signal and the other pair to act as a choke to prevent passage. Two switches (A, B) are provided to effect this selection. One of two further switches (AA, BB) is closed to reverse bias the core winding diodes not needed.

Abstract: 1,084,775. Spray-producers. B. SCHONDORFF [trading as WILHELM HEGENSCHEIDT KOMM GES], Dec. 15, 1964, No. 51046/64. Heading B2F. [Also in Division F2] Workpieces to be cleaned are moved past nozzles providing jets of pressurised water impinging thereon, the nozzles each following a path of rotation in planes located outside the workpieces. In Fig. 1 only one nozzle is shown the other being located on the other side of the workpiece. Each nozzle I is coupled to a head 3 which is rotatable about a water supply pipe 2. The nozzle is rotatably adjustable, under the control of a hand wheel 7, about a radial pipe leading to a further pipe 6 which is similarly adjustable about a tube 4 extending from the head 3. Thus the jet may be adjusted to extend parallel to the axis of pipe 2, at an angle thereto to describe the outline of a cone whose axis is in line with the axis of the pipe 2, or at other angles. In the first two cases mechanical means are employed to effect rotation, and in the third case the reaction pressure will, in some positions, produce rotation. In a modification the head 3 has connections for two nozzles. In other modifications Figs. 6 and 7 (not shown) the supply pipes are carried by pipes which are caused to oscillate or reciprocate. In a further modification. Fig. 5 (not shown) the head 3 is mounted for rotation on a hollow piston rod arranged in a cylinder for limited axial adjustment.

Abstract: 1329131 Power steering VYZKUMNY USTAV STAVEBNICH A ZEMNICH STROJU 27 Oct 1970 [3 Nov 1969] 51065/70 Heading B7H In an hydraulic servo-steering mechanism the spool 3 is so designed that in the neutral position of the spool the inlet channels 11, 11<SP>1</SP> which are each connected to power pumps 13, 13<SP>1</SP>, are connected to by-pass channels 18, 18<SP>1</SP> or return channels 14, 14<SP>1</SP>, and a common intake port 28 is closed by a collar 4 of the spool 3 while return channels 14, 14<SP>1</SP> are closed by collars 5, 5<SP>1</SP>, the inlet and by-pass channels 11, 18 or 11<SP>1</SP>, 18<SP>1</SP> being opened by the axial movement of the spool valve. On clockwise turning of the steering wheel 26 inlet flow sensing member 25 sucks pressurized fluid from conduit 24<SP>1</SP> and directs it via conduit 24 to move the spool 3 to the right against centring spring 8<SP>1</SP>. At the same time channels 20, 20<SP>1</SP> communicate with intake port 28 and return channel 14<SP>1</SP> respectively, spool collars 6 and 5<SP>1</SP> interrupt communication between channels 11 and 18 and channels 11<SP>1</SP> and 18<SP>1</SP> respectively thus opening valves 29, 29<SP>1</SP> so that pressure fluid is delivered via annular groove 10 to the left hand chamber of the cylinder 22 to move piston 27 to the right. Thus the respective part of the steering assembly attached to piston 27 moves the dirigible wheels (or axle) also to the right. Anticlockwise movement of the steering wheel causes the reverse of the above action. Further distributing valves may be connected with the inlet or return pressure conduits 12, 12<SP>1</SP> or 19, 191 for simultaneous operation of other hydraulic systems in the vehicle. When further valves are not connected by-passing channels 18 may be joined with return channels 14<SP>1</SP>. The spool 3 may alternatively be coupled to the steering wheel by mechanical means.
