Title: Improvements in or relating to coin-freed mechanism
Filed: 1960-11-01
Abstract: 914,376. Coin-freeing mechanisms. TOMLINSON, G. Oct. 20, 1961 [Nov. 1, 1960], No. 37457/60. Class 27. The coin shoot of a coin-freeing mechanism has spaced projections 21, 22 on opposite walls to cause a coin to follow a non-rectilinear or sinuous path and to jam on the projections if it is not of reduced thickness within its rim. The base of the shoot is formed by two guide strips 15, 15a pressed out from two walls 10, 11 connected by a spring hinge 13 and the projections comprise two balls 21 inset in the wall 11 and a ball 22 inset in the other wall centrally of the first two. The balls are spaced from the opposite wall and the guide strips from each other by distances equal to or only slightly greater than the rim thickness of a coin and if the coin is uniformly of the correct rim thickness it will not turn sufficiently to pass the projections or if it is thin enough to do so it will be rejected between the guide strips. A peg 16 can be placed in one of several positions near the coin-insertion point 20 to determine the maximum diameter of coin insertable and a magnet 14 is fitted to the movable wall 10 to trap steel discs. As shown, the mechanism is adapted for two coins, the first 17 resting on stops 18, but may be adapted for single coin operation by providing a suitable blank in place of the coin 17 or mounting the stops 18 in suitable alternative positions. The operative coin 19 rests on a balance 23 which, if the coin is of correct weight, pivots to direct the coin to a container and, in passing, the coin operates a lever 24 for displacing the first coin 17. Operation of, for example, a slide or drawer, causes a lever 25 to pivot the wall 10 and release any trapped coins.

Abstract: 1,262,462. Valves. PRIESTMAN BROS. Ltd. 22 July, 1969 [7 Aug., 1968], No. 37632/68. Heading F2V. A valve of the kind which has two contro' members each having a rest position to which it is resiliently urged and from which it is moved to alter the path of fluid flow, comprises a link 18 pivotally interconnecting both control members 8, 11, and an operating member 23 pivotally connected to the link 18, the arrangement being such that initial movement of the member 23 causes movement of one of the control members 11 to its limiting position, and further movement of the operating member 23 causes the movement of the other control member 8 to its limiting position. For equal forces generated by the springs 17, this is achieved by connecting the operating member 23 nearer to one spool 11 than the other 8. The hand lever 27 pivots about fulcrum 28 and is pivotally connected to the operating member 23 at 26.

Title: A synchronizing circuit for controlling a counter circuit
IPC: H03K21/00
Filed: 1961-10-24
Abstract: 932,222. Synchronizing counters. MONROE CALCULATING MACHINE CO. Oct. 24, 1961 [Nov. 9, 1960], No. 38016/61. Class 106 (1). A counting circuit is pulled into a desired synchronism by the application of pulses to gates controlled by the bi-stable circuits making up the counter. In the example shown a Gray-code counter comprises two stages D1, D2 with outputs D1, D1<SP>1</SP>, D2, D2<SP>1</SP> which can be arranged in various ways, one of which is shown at 17, Fig. 2, to indicate a count. Gated clock pulses I<SP>1</SP> are synchronous with normal clock pulses P except that one is missing whenever an external timing pulse I occurs. In the simple embodiment shown the absence of the pulses I<SP>1</SP> has no effect on the counter if it is already in synchronism as in sequence A, Fig. 4, but causes the counter to skip one if not in synchronism. One, two, or three external timing pulses I will therefore bring sequence B, C or D into the desired synchronism. The invention is applicable to a magnetic drum computer in which master, sector index and sector address clock tracks will be unsynchronized when the apparatus is first switched on.

Abstract: 1468940 Carboxylic acid anhydrides HALCON INTERNATIONAL Inc 3 Sept 1974 [4 Sept 1973 8 May 1974] 38511/74 Heading C2C An anhydride of a monocarboxylic acid is prepared by reacting a carboxylic ester RCOOR (Reaction I) or an ether ROR (Reaction II) with an acyl halide RCOX under substantially anhydrous conditions; X is an iodine or bromine atom, the Rs may be the same or different, and each R is a monovalent hydrocarbyl radical which may be substituted, any substituent being inert under the reaction conditions. The acyl halide may be produced by carbonylation of a hydrocarbyl halide (Reaction III) at superatmospheric pressure, using preferably a Group VIII noble metal as catalyst and preferably also a promoter comprising an element of Groups IA, IIA, IIIA, IVB or VIB, a non-noble metal of Group VIII or a metal of the lanthanide or actinide groups. Reaction III may be carried out in a separate reaction zone from reactions I or II, and the hydrocarbyl halide RX formed in I or II recycled to III. Alternatively the anhydride forming and carbonylation reactions may be combined in a single reaction zone; the hydrocarbyl halide, of which no net consumption takes place, may be formed in situ by adding an organic or inorganic halide or elemental bromine or iodine. Reaction II proceeds in two stages, the first step, ROR + RCOX = RCOOR + RX, being followed by I as second step; ester so formed as intermediate may be recovered as by-product. The formation of acetic, propionic, caprylic and benzoic anhydrides from, respectively, methyl acetate, ethyl propionate, heptyl caprylate and phenyl benzoate is exemplified.
