[Class 38 (iv)] [Also in Group XXXVII] In a battery charging system of the type comprising switching means responsive to battery voltage to cause reduction in the charging current when the battery voltage reaches a predetermined value and to interrupt later the charging current when the battery voltage reaches a predetermined higher value. The switching means is responsive to thermally deformable means, (see Group XXXVII), and comprises a heater g connected across the battery a, and a bi-metallic strip actuating in turn through suitable mechanism contact e which either removes a short circuit or a second resistance d<SP>1</SP> (or inductance) from across resistance d (or inductance), and contact f which opens the charging circuit. The contacts are reset manually and the operating value of the device may be adjusted by a variable resistance h included in the heater circuit. The operating spindle of the resistance h may carry an index pointer cooperating with a scale indicating the setting according to the number of cells to be charged. The thermally deformable means may also actuate an index pointer showing the state of charge. Further charging resistances may be brought into service successively by additional switches.

Patent GB-792155-A (GB)
Title: Substituted caprolactone and method for the production thereof
Filed: 1955-06-01
Abstract: The invention comprises a ,d -dimethyl-d -hydroxy-e -caprolactone. The novel compound may be obtained by hydrolysing methacrolein dimer in the presence of excess water and a strong acid, such as hydrochloric, sulphuric, phosphoric or formic acid, at a temperature between 0 DEG  and 150 DEG  C., preferably 90 DEG  to 100 DEG  C., partially neutralizing the reaction mixture with a base to give a mildly acidic medium having a pH of substantially 6.5 and distilling the required product from the reaction mixture.  An inert water-soluble solvent for methacrolein dimer, such as dioxane, may be present during the hydrolysis.  Any inorganic base may be used to effect the partial neutralization but sodium bicarbonate is preferred.  In a detailed example (2), methacrolein dimer is hydrolysed by refluxing with a mixture of dioxane, water and sulphuric acid, the reaction mixture is neutralized to pH 6.5 with sodium bicarbonate, and a ,d -dimethyl-d -hydroxy-e -caprolactone is recovered by distillation.  The compound is reacted with acetic anhydride to give the corresponding acetate.  The lactone may be reacted with butanol to form the butyl ester and then acetylated to form a compound useful as a plasticizer for vinyl resins, and cellulose derivatives.  Polymers may be formed by reacting the lactone with amino acids, polyamines and polybasic acids.  In a comparative example (1), a methacrolein dimer is similarly hydrolysed and then completely neutralized, whereupon the product of distillation is a mixture of 2,5-dimethyl-2-hydroxy-adipaldehyde and 2,5-dimethyl-2-formyl-tetrahydropyran-5-ol.  Specification 725,161 is referred to.

Title: Anti-lock control system for vehicle braking systems
IPC: B60T8/58
Filed: 1976-04-20
Abstract: 1525075 Anti-skid; anti-slip devices TELDIX GmbH 20 April 1976 [19 April 1975] 15958/76 Heading F2F A vehicle braking system has inlet and outlet valves 8, 11 responsive to signals U -b  (indicating wheel deceleration), U b1  (indicating acceleration above a first threshold), U b2  (indicating acceleration above a second, higher threshold), and # (indicating wheel slip). There is also a constant, signal 5 to AND-gate 4 and to the inlet valve 8 to close it. Signal U b1  passes through OR-gate 3 to a bi-stable device 1, which, when the signal ends, emits a signal through time extension elements 6, 7. During the operation of the element 6, a signal, acting through negator 9, negates the signal 5 so that the inlet valve 8 is opened. The element 7 feeds a negative signal to the AND-gate 4 to block the input to element 6. At the end of the time defined by element 7 the cycle starts again. The effect of the U b2  signal is to block energization (i.e. closure) of the inlet valve 8, via line 12, so that brake pressure builds up, and also to start a cycle based on the time extension element 15. In another embodiment (Fig. 2, not shown) a step counter switched by pulses, e.g. at 60 millisecond intervals is used.

Title: Improvements in woven fabrics and moulded articles
IPC: D03D25/00
Filed: 1958-05-30
Abstract: 894,652. Weaving shaped fabrics. KOPPELMAN, E. May 30, 1958 [June 5, 1957; April 23, 1958], No. 16253/61. Divided out of 894,651. Class 142(4) A fabric consisting of spaced upper and lower plies inter-connected by vertical transverse ribs is woven in collapsed condition. As shown in Fig. 2, four layers of warp 42-45 are first woven together in pairs, then woven separately at 47 for a distance equal to half the height of a rib, and woven together at 50; the rib-forming warps are then lifted above the upper ply and looped over a few thick weft threads 54, after which they are woven together at 56 and separately at 49 to form the next rib. On cutting the projecting loops of warp thread, the upper and lower plies can be separated to bring the fabric to its erected form with the ribs 47, 49 straight and vertical. If the same shuttle inserts weft in all the plies, it is also necessary to cut the weft where it passes from one ply to another at the edges of the fabric. In this case, Fig. 4, the weft is interwoven with groups of warp threads spaced from the edges of the fabric to produce false selvedges 63 which are discarded when the weft is subsequently cut. The thick wefts 54 are taken to other false selvedges 58, whereby they can be held taut in a tentering machine whilst the warp loops passing over them are cut; the false selvedges are cut off by knives 65. Alternatively, the warp loops passing over the wefts 54 may be ruptured by an abrasive roller. The fabric may be woven from three layers of warp threads, the whole of every rib being woven from the middle layer, which interweaves with the upper and lower plies of the fabric alternately and loops over thick wefts 54 between successive ribs. Two such fabrics may be woven simultaneously in a double velvet loom, the rib-forming warps crossing from one fabric to the other after weaving a rib so as to be cut between the fabrics by the usual knife. Fabrics erectable to a tapered shape, Fig. 1A, can be produced by interweaving the ribs with the upper and lower plies along diagonal lines. Ribs may also be formed in fabrics of curved shape woven as described in Specifications 871,742 and 871,743 (Group IX). The various fabrics may be woven from glass, nylon, or cotton and used as reinforcement for synthetic resin articles. They may be woven from wire, in which case the crossing points of warp and weft may be secured together by dipping the erected fabric in solder or braze metal or by weaving it from wire coated with such metal and heating after erection.
