Title: Cylinder Lock
IPC: E05B27/00
Filed: 1968-06-19
Abstract: 1,193,760. Cylinder locks. GENERAL ALARM CORP. 19 June, 1968 [28 June, 1967], No. 29127/68. Heading E2A. A cylinder lock, incorporating means for actuating an alarm if an attempt is made to pick the lock, by applying a torque to the barrel and raising successive pins until the shear line is felt, and at the same time frustrating such attempt, comprises a key-operated barrel 12, which incorporates at least one pin 16 associated with a standard driver 17 and spring 19 located in a bore 15 of the cylinder casing, a second barrel 11 arranged side by side with the first barrel so that the juxtaposition of the two barrels forms an extension of the shear line, and pins 21 cooperating with non-standard driver assemblies in normally aligned bores 11a, 12a of the two barrels, the non-standard driver assemblies being designed such that, when the standard pin and driver have been picked by the above method, limited rotation of both barrels in opposite directions occurs through the interconnection provided by the non-standard driver assemblies, resulting in rotation of an axial extension 31 of the barrel 11, which causes, an arm 32 to operate a micro-switch in an alarm, circuit. In the embodiment of Figs. 1 and 2, each of the non-standard driver assemblies consists of an axially short driver 22 and a spring having a close-wound portion which normally extends across the shear line. As a result, as soon as the pin 16 has been picked, the barrel 12 is freed and rotary motion is transmitted to the barrel 11 by the springs of the non-standard assemblies, sucn relative rotation however being limited by interference between formations 27, 29 on the two barrels, which prevents the bolt from being completely withdrawn. By the provision of a spring-loaded ball 40 in barrel 11 engageable with either of two recesses 42 in the casing, the barrel 11 is locked in the alarmoperating position. A further spring-loaded ball is provided in a bore 50 in the casing cooperable with a recess 47 in the barrel 11 to releasably hold the latter in its normal position when the correct key is inserted, so that in this case barrel 12 rotates independently, the portions 27, 29 do not interfere, and the bolt is withdrawn. In a second embodiment, Fig. 7, each of the non-standard driver assemblies consists of a spring 44 and a driver 45 which co-operates with an enlarged bore 11b in the barrel 11, thus eliminating the need for the interfering formations, 27, 29 of the previous embodiment.

Title: Preparation of solutions of calcium chlorate poor in chloride
IPC: C01B11/14
Filed: 1945-11-06
Abstract: Calcium chloride is removed from calcium chlorate solutions produced by reacting chlorine with milk of lime by adding 1 to 1.2 mols. of calcium oxide or hydroxide per mol. of calcium chloride and maintaining the solution above 35 DEG  C. and above a soluble calcium concentration of 3 mols. per kilogram to form and eliminate CaCl2.Ca(OH)2.H2O.  Lime may be added as powder, granules, milk or suspension, or may be formed in situ by adding alkali hydroxide to the solution.  In a cyclic process calcium chloride may first be crystallized by evaporation and the filtrate treated with lime slurried with water and some of the final calcium chlorate liquor. The precipitated CaCl2.Ca(OH)2.H2O is decomposed with water forming lime which is recycled for reuse and calcium chloride solution which is recycled to the evaporator and to wash the basic chloride on the filter.  Intimate mixing with stirrers or pumps promotes the reaction.  A statement of prior art describes the formation and precipitation of CaCl2.3 Ca(OH)2 12 H2O, together with excess lime, the process involving heating and cooling.  The Specification as open to inspection under Sect. 91 describes the purification of alkaline earth chlorates in general including barium.

Filed: 1955-10-20
Abstract: 788,882. Knitting-machines. SCOTT & WILLIAMS, Inc. Oct. 20, 1955, No. 30021/55. Class 74 (2). During continuous rotary or reciprocatory knitting especially when large loops are being formed, as during the knitting of a welt on a circular machine, the sinkers are given an additional inward movement after the loops have been cast off and as the needles rise and latch opening occurs. The tendency for loop distortion as the yarn opens the latches of the needles is thereby reduced by the sinkers holding the loops about the needles. The sinkers are also given another inward movement after the needles have been raised by the forward stitch cam to clear their latches so as to restore the slope of any distorted stitches which may have become so distorted as they pass over the spoon of the latches. For the purpose of providing the additional sinker movements. pivoted cams 22 and 20 are positioned immediately following the casting-off cam 18 and at a position following the incline of leading clearing' cam 46 respectively. During reciprocatory knitting the two cams reverse their functions, the cam 18 being inoperative and a casting-off cam on the other side of the centre cam being operative. The invention may be applied to a two or more feeder machine. Specifications 102,711, [Class 74 (ii)], 651,961 and 704,843 are referred to.
