Title: Improvements in or relating to locks for the doors of safes, strong rooms and the like
Inventor: LEA ERIC
IPC: E05B13/00
Filed: 1960-07-29
Abstract: 936,155. Safes; sliding bolts. RATNER SAFE CO. Ltd. June 1, 1961 [July 29, 1960], No. 26605/60. Class 44. Relates to locking apparatus of the kind comprising one or more bolts, bolt-operating means for moving the or each bolt between shot and retracted positions and bolt-locking means operable to prevent withdrawal of the or each bolt out of its door-locking position. According to the invention the apparatus includes at least one bolt tail for the bolt or bolts, such tail being formed in two parts which are movable relative to one another and coupling means for interconnecting the two parts only when the bolt locking means is in its unlocked position the bolt-operating means being arranged to act upon that part of the bolt tail which is uncoupled from the door bolt or bolts when the bolt locking means is in its locked position. As shown, a bolt bar 1 carrying a pair of bolts 2 includes a bolt tail 3 which co-operates with a lock bolt 4 of locking means 5, and a bolt tail 6 which is formed in two parts 7, 8 which are loosely connected by a coupling 9 engageable with slots 10 in the bolt tail 6. The part 8 of the bolt tail 6 is engageable by an arm through which both bolts 2 are movable by a handle 14 within limits imposed by pin-and-slot devices 15, 16. The coupling 9 is supported by a platform 7 which is rigidly connected to the bolt 4 through a shank 18<SP>1</SP>, the arrangement being such that in the unlocked position of the locking means 5, the bolt tail parts 7 and 8 are connected together by the coupling 9 and the bolts 2 may be moved to their shot position by the handle 14. If the locking means 5 is subsequently locked, bolt 4 blocks the bolt bar 1 and the parts 7 and 8 are disconnected. A flange 19 on the part 8 overlies one side of the part 7 such that if the handle 14 is operated while the locking means 5 is locked and the parts 7 and 8 become separated, the coupling 9 becomes blocked by the flange 19 and thus prevents unlocking of the locking means 5. In an alternative form the coupling may be arranged to encompass two projections depending one from each of the adjacent ends of the bolt tail 6. Specification 770,431 is referred to.

Title: Improvements in or relating to ternary coded ticket reader
IPC: G06K7/08
Filed: 1966-06-16
Abstract: 1,101,978. Ticket-controlled passenger barriers. LONDON TRANSPORT BOARD, and R. DELL. 16 June, 1966, No. 27010/66. Heading G4T. In a public transport ticket-controlled barrier system a plurality of passenger operated ticket readers and associated barriers are multiplexed to a single electronic processing unit which checks the ticket (date of issue, departure station, fare paid &c.) and as a result causes the ticket to be retained or returned to the passenger (e.g. at interchange stations) and appropriately controls the barrier. Tickets are sensed magnetically by a reader with heads so arranged that the ticket can be inserted face upwards or downwards or forwards or backwards. The direction (i.e. forwards or backwards) of entry is determined by direction signals on the ticket which cause the data read from the ticket to be clocked into one of the registers in such a way that the resulting format of the stored data is always the same. A ternary code using two binary bits for each ternary element is employed. The registers of the plurality of ticket readers are interrogated cyclically by a central processor which, from data set on multi-position switches and from data determined by the particular wiring configuration of various diode matrices, determines whether to return the ticket and whether to open the barrier. An outline circuit is described using conventional semi - conductor switching techniques.

Patent GB-272951-A (GB)
Abstract: 272,951. Consortium f³r Elektrochemische Industrie Ges. June 17, 1926, [Convention date]. Acetic anhydride.-In the production of acetic anhydride by heating the vapour of acetic acid in presence of a catalyst at 400-800‹ C. for instance as described in Specifications 194,719 and 230,063, the vapour is preheated to a temperature between 400 and 800‹ C., advantageously 400-700‹ C. and is then treated with the catalyst. The preheating may be effected in apparatus the heating surfaces of which are made of carbon, silver, copper, chromium-steel, nickel-steel or other materials such as those mentioned in Specification 273,923; for instance the vapour may be passed over electrically heated resistances of carbon, graphite or nickel or chromium alloys. When the catalyst: is molten alkali phosphate in a carbon crucible, as described in Specification 230,063, the preheating increases the output per hour tenfold. In an example, the vapour of acetic acid is led through a tube of V2A (of Krupp's) heated externally to 700‹ C. by fire-gases to a chamber containing the catalyst at about the same temperature. It is advantageous to use the gases which heat the reaction chamber to heat the preheating tube subsequently, so that the acetic acid vapour passes in counter-current to the heating-gas. It is also possible to use the heat of the reaction product for the preheating. The Specification as open to inspection under Sect. 91 (3) (a) states that the preheating tube may be made of Duraloy (of the Duraloy Company of Pittsburgh) and that the catalyst may be aluminium phosphate upon a carrier, heated to 600-800‹ C. This subject-matter does not appear in the Specification as accepted.

When a bellows M is expanded by heat, its pin P raises the lever B, allowing the valve G to be rapidly opened by the compressed air acting on the piston H. The air then passes to raise a piston W<1> which tilts a lever X, allowing the air to open a valve Y and pass to the alarm Z. Further, air passes by the pipe F<1> to actuate the release mechanism of a fire-extinguisher, e.g. the valve lever H<1> of a gas cylinder K<1> which discharges extinguishing gas through a nozzle M<1>. A number of valves G are associated each with a piston W<1>, any piston acting to tilt the lever X through a common arm A<1>. The pistons give an indication as to the locality of the fire. The spring T loading the lever B is adjustable by a nut U, and the bellows M is heat insulated, as by insulation Q. After actuation, the valves G are reset merely by turning off the compressed air. In a modification, the bellows acts through two levers biassed by a spring or adjustable weight.
