Title: Improvements in or relating to remote electric control systems
IPC: B63H21/22
Filed: 1933-12-05
Abstract: 434,717. Distant-control and signalling systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and COATES, H. J., c/o General Electric Co., Witton, Birmingham. Dec. 5, 1933, No. 34185. [Class 40 (i)] In a remote control system, particularly for use on ships, the controlled apparatus is controlled either by a remote transmitter, for example on the bridge or locally, for instance in the engine room, in response to signals given by the transmitter. As shown a transmitter 85 is adapted either to control directly a regulating resistance 4 or operate signalling apparatus 111, 96 alone so as to indicate to a local operator the position to which the regulator is to be set. The local control is effected electrically or mechanically from a handle 54. Direct control by master controller. Operation of the handle 106 on the bridge causes operation of a bell 111 by the contact mechanism 86, 104, and a resultant field indicator 96 by the variable potentiometer 89. A second potentiometer 93 is connected in a bridge circuit with potentiometer 27 in the engine room and the arrangement is such that when the handle 106 is moved, the balance is upset and the bridge relay 35 is operated to cause rotation in one or other direction of a motor 32 which controls the regulator 4 and simultaneously adjusts the potentiometer 27 until the bridge circuit is rebalanced. Local control. If it is desired to effect local control, a switch 115 is operated from the bridge to disconnect potentiometer 93 and connect to the bridge relay a potentiometer 56 controlled by the local control handle 54. In response to signals transmitted from the master controller and operating the bell 111 and indicator 96, the local operator operates the handle 54 and the engine regulator is driven by the motor 32 under the control of the auxiliary bridge-circuit in a manner similar to that already described. The local control means also operate an indicator 65 and bell 80 on the bridge to signal an acknowledgment of the transmitted order. A clutch mechanism 28 is provided to facilitate disconnection of the motor 32 and the direct mechanical control of the regulator 4 by the handle 54.

Abstract: 1,236,235. Camera shutter control. EASTMAN KODAK CO. July 18, 1968 [July 21, 1967], No.34264/68. Heading G2A. A pivoted shutter blade 10 having lugs 48, 50 is locked in its closed position over an exposure aperture 100 by a latch 46 engaging the lug 50 and is operated by an electromagnetic system which first pivots a cross-bar 16 to compress a spring 34, and then releases the latch 46 so that the spring 34 rotates the blade 10 away from the aperture 100 and into engagement with a latch 44; the shutter being closed by a similar, separate operation. Each spring 32, 34 has one end mounted in the bar 16 and the other in a cap 40, 42 joined to a pivoted bar 36, 38. In one embodiment, the shutter is opened by energizing a solenoid 22 which attracts a plunger 18, joined to the bar 16, and pivots the latter to compress the spring 34 until a set screw 78 strikes and releases the latch 46. The shutter is closed by energizing a solenoid 24. Alternatively, the latch 46 may be released by energizing a solenoid 86 to display vertically a plunger 90 which strikes a lever 54b joined to the latch 46. A solenoid 84 is provided to release the latch 44. Alternatively, the solenoid 22 may be energized to pivot the bar 16 so that the latter closes a switch (104), Fig.3 (not shown) to energize the solenoid 86, causing the plunger 90 to release the latch 46 and open the shutter, which may be closed by similar, sequential operation of solenoids 24 and 84.

Abstract: 1,134,374. Monoazo dyes. CIBA Ltd. 26 July, 1967 [29 July, 1966], No. 34292/67. Heading C4P. The invention comprises water-insoluble azo dyes of formula R 1 -NH-R 3 (N0 2 )-N = N-R 4  wherein R l  is a phenyl residue, R 3  is a pphenylene residue containing the nitro group in meta-position to the azo group and R 4  is a phenyl residue containing a hydroxyl group in ortho-position to the azo group. The dyes are prepared by condensing a 21-hydroxy-azobenzene containing in the 4-position a halogen atom and in the 3-position a nitro group with an aminobenzene. The starting materials are prepared by coupling a diazotized 4-halo-3- nitroaniline with a phenol. The dyes are used to colour fibrous materials of cellulose acetate, polyamides and, in particular, polyesters in yellow to red shades.

Abstract: 1402263 Method of diagnosing pregnancy in cows NATIONAL RESEARCH DEVELOPMENT CORP 21 July 1972 [22 July 1971] 34519/71 Heading A1M [Also in Division Gl] Diagnosis of pregnancy in inseminated cows is made by a series of progestagen assays of their milk to detect any increase in its concentration. Where the sequential tests do not show one or more levels well below the midcycle value found in non pregnant cows the test can be taken as positive. The assay is carried out at least 20 days after insemination and preferably within 55 or 85 days of insemination. The assay may be performed every 3 or 4 days in the 20-28 day period and every 5 or 6 days in the 50-70 day period so that fluctuations in the progestagen concentrations can be detected. The progestagens may be estimated by a protein binding method after removal of lipids from the milk or by a radio-immuno-assay on whole milk.

An apparatus for inserting a block of cigarettes, with or without a tin-foil wrapper, into an open-ended container, comprises a turret 2 for presenting each empty carton in turn to a position IV in the path of a linear feed track, a first member 5 reciprocating along the track to receive the cigarettes from a guide 7 and feed them into the container at IV, and a second member 9 reciprocating along the track to receive each filled container and convey it for continuing movement along a guide 8. Feeding cartons. The intermittently rotating turret 2 carries a number of pockets 3. At station I the pockets each receive a carton supplied by a plunger 4. As each pocket 3 approaches station II its motion causes an initially stationary folding blade 15 to elevate the wide lower flap 25 of the carton. A slider 14 then reciprocates along a guide 13 to cause the blade 15 to push the flap 25 into the carton through 180 degrees, the wide upper flap 26 being also folded through 180 degrees by a following cam controlled blade 16 at station III, cam controlled blades 17, similar to the blade 16, are reciprocated to fold the narrow side flaps of the carton inwards by 180 degrees. At station IV the carton is aligned with the feed track for the cigarettes. Cam controlled means within the turret 2 causes the pockets 3 to adopt the various positions shown during the rotation of the turret. Feeding cigarettes into cartons. A continuously moving chain 10 has lugs 11 that withdraw each block of cigarettes from a guide 7 and inserts it in a supply pocket 5. Continued movement of the lug 11 moves the supply pocket 5 from the position shown in chain dot lines to that shown in full lines wherein a mouthpiece 6 of the pocket 5 enters the carton at station IV. The lug 11 then pushes the cigarettes through the pocket 5 and into the carton, whereupon the pocket 5 returns to its original position. The continuous movement of the lug 11 then pushes the cigarette filled carton from the pocket 3 at station IV and into a pocket 9 that moves with the lug 11 to the position shown in chain dot lines whereafter the lug 11 pushes the cigarette filled carton through the pocket 9 and into guides 8 for removal to a following working station, the empty pocket 9 returning to the full line position.
