IPC: G08B5/28
Filed: 1958-09-26
Abstract: 903,721. Visible signalling-apparatus. CHAMBERLAIN & HOOKHAM Ltd. Sept. 21, 1959 [Sept. 26, 1958], No. 30776/58. Class 118. A semaphore indicator, for indicating the condition of a remotelydisposed switch, comprises a disc which is angularly movable between two positions by electromagnetic means, the electromagnetic means being energized only momentarily to effect each change of position of the disc. An electromagnet 11 is connected to a source of electric current through a changeover switch 21 and also through a second change-over switch (not shown), the latter being actuated in synchronism with the switch whose condition is to be indicated. The circuit is arranged so that actuation of the second change-over switch will cause energization of the electromagnet thereby attracting a spring-loaded armature 12 to operate the switch 21 which then breaks the circuit and allows the spring- loaded armature 12 to return to its original position, the two change-over switches thereupon forming an alternative circuit ready for the next energization of the electromagnet. The armature 12 of electromagnet 11 is connected to a spring-loaded pawl 14 operating a ratchet 16 which rotates upon a spindle 17 suspended between two plates 18 upstanding from the base of channel 7. At each end of the spindle 17 are square-shaped cams 19, 20, cam 19 being connected by a spring leaf 22 to changeover switch 21 and cam 20 to a spring-loaded lever 23 connected via pivoted lever 26, eccentric pin 28 and spindle 29 to the indicator disc 24 such that movement of the ratchet changes both the position of the switch 21 and the position of the disc. It is arranged so that if in either of the two positions angular movement is imparted to the disc to move it to the alternative position, other than by actuation of the cam 20, then the disc returns to its correct position as soon as it is released under the influence of either spring 27 or the two levers 23, 26 and spring 25. Specification 903,723 is referred to.

Filed: 1957-10-02
Abstract: 864,008. Grinding gears. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 30, 1958 [Oct. 2, 1957], No. 30889/57. Class 60. [Also in Group XXII] A gear cutting or grinding machine comprises a gear profile generator 9 on a carriage 8 reciprocated by a differential device 5 which is so controlled when the carriage motion is reversed after a working stroke as to cause the carriage to return to a correct position for generating the next tooth. The gear blank 1 is rotated by a motor 3 through a gear box 2. The motor also rotates a screw 7 through the differential gear 5 having a further input from a motor 11. The screw moves the carriage 8 carrying a rotary plane-sided cutter 9. At the end of its forward travel, the carriage 8 operates a switch to energise the motor 11 which rotates a shaft 10 at such a speed as to reverse the direction of travel of the carriage 8. Selsyns 13, 15 are rotated by the motor 11 and are interconnected by gearing 12 so that when the coarse selsyn 15 is at its initial position and the fine selsyn 13 is re-aligned at its initial position, the shaft 10 will have been rotated through the desired number of turns. The cutter, when re-engaged, will then engage the gear an integral number of pitches from the initial cut. In operation, the motor 11 is initially started by a mains supply but control is subsequently transferred to the selsyns. In a modification, the selsyns are replaced by revolution counters which produce an error signal. The screw may be parallel to the blank axis as shown when producing a helical gear, at an angle to the axis for spiral bevels or at light angles to the axis for spur or bevel gears. Specification 825,833 is referred to in the Provisional Specification.

Title: Capacitative or inductive coder
IPC: H03M1/00
Filed: 1962-08-14
Abstract: 1,001,146. Electric selective signalling systems. B. LIPPEL. Aug. 14, 1962 [Aug. 16, 1961], No. 31171/62. Heading G4H. A shaft position digitizer comprises a plurality of groups of appropriately shaped rotor plates which co-operate with appropriately shaped stator plates, the latter being arranged so as to be equivalent to "lead and lag " sensing brushes. The embodiments described use capacitative coupling but it is stated that inductive coupling could be used. In a first embodiment, Fig. 1, each group 1, 2, 3 of plates-the rotors A and stators B being shown respectively in Figs. 2, 3 and 4-produces one bit of pure binary output, and each group, except the least significant, has lead and lag segments. A circuit for sensing the positions of the various rotor plates is shown in Fig. 5. In operation a source 74, Fig. 5, applies a pulse to all the rotor plates which pulse is capacitatively coupled, in varying degrees, to the stator plates. The pulse induced in the least significant stator plates 100 is applied to an amplitude discriminator 79 which produces, in accordance with the pulse amplitude, the least significant output bit D1 and which also opens a " lead " or " lag " gate 57, 59, for the next higher denomination, in which the " lead " and " lag " plates 54 are labelled A and B respectively. In a similar way the second output bit D 2  controls the choice of " lead " and " lag " gates for the third bit, and so on. In a second embodiment a complete rotation of the shaft is divided into 100 divisions and a binary-coded decimal output is produced. As a modification of either embodiment it is stated that a high order plate and a low order plate may be combined concentrically, Fig. 12A, to economize on space, especially when the plates are " printed." Specifications 650,913 and 819,252 are referred to.

Patent GB-317907-A (GB)
Abstract: 317,907. Dreyfus, H. May 26, 1928. Aliphatic acid anhydrides are produced by heating the corresponding, acids especially acetic acid, in presence of non-metallic inorganic or organic bases such as ammonia, primary, secondary, and tertiary alkyl-amines, tetralkylammonium bases, pyridine, picoline, quinoline, piperidine, aniline, alkylanilines, cyclohexylamine, toluidine, &c. or their hydrochlorides, sulphates, phosphates or other salts. The reaction may be effected at 200-700‹ C. in fireclay, silica, copper or other tubes, and the bases may be employed in solid or liquid state, preferably upon balls of pumice, kieselguhr, carborundum, &c. where the base, such as benzidine or tolidine, is relatively non-volatile, or in other cases a mixture of the vapours of the acid and base such as ammonia or ethylamine may be passed through the tube containing pumice, &c. balls, and the reaction zone may also contain a solid, liquid or gaseous catalyst known to promote the formation of the anhydride or one of the relatively non- volatile bases. Reduced, normal or increased pressure, such as 5-10 atmospheres, may be employed. In an example, a mixture of acetic acid and 2-7 per cent of ammonia is passed through a copper or silica tube at 550-600‹ C. The anhydride may be separated from the reaction vapours in any suitable way. The reaction vapours may be passed in contact with an acid stronger than the aliphatic acid initially used, such as phosphoric or hydrochloric acid, so as to neutralize the bases, before the separation of the anhydride, and the separated anhydride may be purified by treating with phosphoric or hydrochloric acid and distilling over anhydrous sodium acetate. The reaction vapours may be fractionally condensed by passing through columns at termperatures between the boiling-points of water and the anhydride, or may be passed through a solvent insoluble in water at temperatures between the boiling-points of water and the anhydride, mention being made of chlorbenzene, p-dichlorbenzene, benzyl ether, tetrachlorethane, paraffin oil, triacetin, phenetol, anisol, cresols, or pcresyl acetate. Or the reaction vapours may be condensed while carrying away the water vapour by the vapour of an entraining liquid as described in Specification 303,772, the liquids mentioned therein or toluene, xylenes, or other solvents of boiling point intermediate between those of water and the anhydride, being used; or they may be passed under the surface of an " extracting liquid " as described in Specification 298,667; or they may be passed over water-binding substances as described in Specification 289,972; or they may be caused to impinge upon the surface of a flowing stream of benzene &c. as described in Specification 310,863. When pressure is employed, it is preferred to release the pressure before the separation of the anhydride. The initial material may be in concentrated or dilute form. Specifications 257,968 and 280,972 also are referred to.
