Abstract: 1283795 Stud and socket fastenings RUBERY OWEN & CO Ltd 19 April 1971 [14 March 1970] 12389/70 Heading E2B Releasable means for securing a freight container to the platform of a trailer or the like comprises a spindle 7 and head 6 which are supported in a projected position by two cooperating superimposed abutment members through which the spindle passes, the upper abutment member 10 is of inverted U shape and is guided in a housing for vertical sliding movement therein with the spindle and head, and the lower abutment member 13 is of U shape is angularly movable in the housing between a position in which the limbs of the two members are in vertical alignment and abut and a position in which the limbs are out of alignment and the members can rest together in a vertical direction to allow the head to be retracted into the housing. A sleeve 8 secured to the spindle provides an abutment for supporting the member 10 for axial movement with the spindle. The lower member 13 has a spigot 15 which engages in a hole in a plate 4 of a housing and is retained against axial movement by a spring ring 16. A collar 17 is rotatably mounted on the spindle 7 and has a downwardly projecting peg 19 movable in a notch 20 in a flange 18 at the lower end of the spindle and an upwardly extending peg 21 engageable in any selected one of a number of notches 22 in the lower end of the spigot 15. The collar has an operating handle 23. In operation the spindle 7 is moved upwardly to raise the head 6 above the plate 1 and to raise the member 10 above the member 13, the peg 21 then engages a notch 22 of the spigot. The collar 17 is then turned through 90‹ rotating with it the member 13 so that limbs of members 10 and 13 abut, and the head is pivoted through an elongated opening in a container corner casting. The collar is turned through a further 90‹ thereby rotating the spindle and head into the fastening position, the lower abutment limbs being turned out of alignment with the limbs of member 10. The limbs can be realigned by turning the collar back through 90‹. To release the container the collar is turned back through a further 90‹.

An optical system 16, 17, 18, 19 may be built into the apparatus for viewing an enlarged image on a ground glass screen 20 in the apparatus or for projecting an increased enlargement on a separate screen, thus deflections as small as 0.01 mm. can be detected.
Patent GB-1086238-A (GB)
Title: Improvements in electronic data processing system with time sharing of memory
IPC: G06F13/22
Filed: 1966-03-21
Abstract: 1,086,238. Data processor; digital data storage. GENERAL ELECTRIC CO. March 21, 1966 [April 14, 1965], No. 12411/66. Headings G4A and G4C. A data processor includes a memory having a first word time and one or more peripheral units having a word time different to that of the memory, and a device for dividing successive first word times into a plurality of phases and a device for allocating one of the phases to a peripheral unit. The word time is the time taken to prepare components for making or accepting the transfer of a word and the time taken to transfer the word, the time involved in the actual transfer being a small portion of the total time occurring at approximately the centre of the respective word times. The memory word time is divided into eight pulses T0-T7 and the T0 pulse is supplied to a phase counter (54, Fig. 16, not shown and Fig. 3, not shown) to produce three phase pulses #1, #2, #3 of a period equal to the memory word time. The three phase pulses are fed as one input to AND gates (72, 74, 76, Fig. 1a, not shown). Each peripheral device (28, 30) having a word time different to the memory has its own internal timing generator (62, 68) triggered by the phase counter, one generator (62) triggered by pulse #1, and having eight internal pulses T0<SP>1</SP>-T7<SP>1</SP>) the other (68) triggered by #<SP>2</SP> (and having eight pulses T0<SP>11</SP>-T7<SP>11</SP>). When each peripheral unit wishes to store or receive data it transmits a signal to the said AND gates (unit 30 to gate 76 and unit 28 to gate 74). Thus one AND gate is enabled for period #3 and the other for period #2. The enabled AND gate sets a flip-flop (FF7, FF6) which enables one of two inputs to a pair of AND gates (100, 102 or 96, 98 respectively). The appropriate gate is enabled by a signal from the peripheral unit indicating whether a reading or writing operation is to be performed. The output from the AND gate then enables either a gate (38, 42) feeding data to the memory (10) or a gate (46, 48) feeding data from the memory. The short transfer period occurs during internal pulse T4<SP>1</SP> for one unit (28) and during pulse T4<SP>11</SP> for the other unit (30). Different peripheral units may be used having word times differing from each other, and some may have times equal to the word time (unit 26 operating flip-flop FF5 in Figs. 1a, 1b).

[Class 135] Means for automatically opening the supply valve a of a steam-driven pump when an electrically-driven pump fails, and for enabling the valve a to be closed when the electricallydriven pump is again operative comprise an alternately seating spring-loaded control valve k having a collar n held by the feed pressure from the electrically-driven pump to close an exhaust passage f<1> so that the said pressure acting through a conduit e on a piston b holds the main valve closed against the action of a spring c. On failure of the feed pressure, the passage f is opened and simultaneously the lower end of the valve k closes an inlet h<1> to a chamber h connected by a passage i, having a manually adjustable valve j, with the chamber f leading to the passage f<1>. In this way, leakage to the exhaust passage f on restoration of the feed pressure in the inlet h<1> is avoided. The valve k is reset by an elbow lever p which overcomes the spring load m of this valve. Specification 13346/99, [Class 102], is referred to.
