Patent GB-946716-A (GB)
Title: Line casting machines
IPC: G05B19/14
Filed: 1961-11-14
Abstract: 946,716. Type-bar making machines. STAR PARTS Inc. Nov. 14, 1961 [March 14, 1961], No. 40759/61. Heading B6W. A line casting machine is controlled by a tape 15 having one or more code holes, such as 0-5, and a pulsing hole M at each reading position, and comprises a source of light L on one side of the tape, a plurality of photodiodes P 0 -P 5  on the other side of the tape located in the path of the code holes to be activated by light passing therethrough and a pulsing photo-diode P M  in retard of the other photo-diodes to be activated by the pulsing  hole M. The signals from the photo-diodes P 0 -P 5  are amplified and by means of transistor flip-flops close either of two lines associated with each diode to indicate either " hole " or " no-hole " at a given position; by this means an electric signal path is opened corresponding to the information represented by the code hole(s) at a given reading position of the tape. This path leads to a solenoid which actuates one of the keys on the keyboard of the machine so as either to release a matrix from the magazine or to perform some other function. Once the path has been opened a pulse is sent along it by means of a transistor flip-flop associated with the photo-diode P M  and the corresponding solenoid is thereby actuated. When the same character is repre-  sented on the tape twice in succession a delay is introduced in the pulsing circuit and the tape feed is momentarily arrested so as to allow the second of the characters to fall to a position in which it can be released from the magazine. The tape 15 is fed over the light source L by means of driven rollers 21, 21a with which the tape is held in contact by spring-biased pressure rollers 22, 22a; when it is necessary to interrupt feeding of the tape a solenoid 25 is actuated which causes a lever 23 to pivot about a fulcrum 26 and lift the tape out of contact with the roller 21 whereby it is no longer advanced. Assembling elevation (Fig. 13). The elevator 101, for raising an assembled line of matrices to a delivery slide, is raised and lowered by a crank 110 driven through a one revolution clutch 100 operation of which is initiated by an " elevate " signal. It is mounted on a rod 116 which can be raised manually if desired, the rod sliding in outer tube 115. Movement of the elevator stops the feed of the control tape. If the " elevate " signal is received when the elevator is not in its lowest position, or the delivery slide is not in its receiving position, the signal is stored until these defects have been rectified. If the elevator meets an obstruction while rising, a switch is actuated and the elevator is lowered. When the fault has been cleared, the switch is reset and the cycle is repeated. Specification 946,717 is referred to.

Title: Improvements in or relating to the manufacture of electric discharge lamps
Inventor: WILLIAMS CHARLES EDINGTON
IPC: H01J9/22
Filed: 1960-11-29
Abstract: Method of manufacturing a fluorescent discharge lamp, e.g. a low-pressure mercury vapour lamp, comprises coating the envelope with a suspension of phosphor powder in a liquid containing a binder, drying the coating, baking the envelope in air at a temperature such that the binder volatilizes, allowing the envelope to cool to room temperature, washing the phosphor coating with a dilute aqueous solution of an acid, and drying the coating. The coating can be washed with distilled water before drying. The acid can be acetic, formic, hydrochloric, nitric, sulphuric, citric or tartaric acid and the concentration of the aqueous acid solution is 0.1 to 10% weight/volume or volume/volume.  If the acid is only slightly soluble in water a solubility-increasing substance can be added.  The Provisional Specification refers to ethylene diamine tetraacetic acid in a dilute aqueous solution of ammonia.  The acid washing treatment can be effected by filling the envelope with the acid solution, holding it full for a period of 10 minutes to 2 hours, and allowing the solution to drain away. The phosphor coating is dried by passing a slow current of air, heated to a temperature of 100 DEG  to 200 DEG C., over the coating. After drying the phosphor coating can be subjected to a second baking process in the presence of an oxidizing atmosphere.  The phosphor can be calcium chloro-fluoro-phosphate activated by antimony and manganese and can comprise particles smaller than 30 microns, e.g. particles of 5-25 microns prepared by the cyclone classification process described in Specification 927,354.  The binders can be nitrocellulose, and water-soluble ammonium polymethacrylate.

Abstract: 1435777 Watches A SCHILD SA 6 Sept 1973 [14 Sept 1972 15 July 1973] 42027/73 Heading G3T In an automatic winding mechanism with an eccentric weight 9 which drives a winding train 11-14, in one direction of oscillation only, by means of a pinion 7 fixed to the weight and meshing with a gear 10 which is mounted on a lever 19 and is brought into mesh with wheel 11 in the said direction of oscillation, reverse motion of the train being prevented by a pawl 20, both the lever and the pawl are subject to the action of a spring 21 and to facilitate assembly, the spring is initially inoperative as in Fig. 1, thus relieving the train shaft pivots, and is loaded after assembly by means of a member 23 which can be actuated from outside the mechanism. As shown the member 23 is a resilient part fixed to watch plate 1 by its foot 24 and having near its free end a projection 25 engageable in a recess 27 in the plate. In this position the weight 9 and pinion 7 can be placed on shaft 4, rotation of the weight being prevented by a projecting loop of the member 23. An aperture (31) Fig. 3, (not shown), is provided in bridge 15  so that a tool may then be inserted to release the projection 25 which becomes displaced to recess 28. The free end 26 of the member 23 then holds the weight against axial displacement while its rotation is permitted. A lug 29 on the member deflects the central portion of the spring 21 so that the pawl 20 is brought into engagement with the wheel 11 while the free end of the spring biases the lever 19 anti-clockwise to bring the gear 10 into mesh with the wheel 11. Winding occurs during anti-clockwise rotation of the weight; in the other direction the pawl blocks the wheel 11 while the gear 10 rides out of mesh with that wheel. In an alternative embodiment, the spring (61), Fig. 4, (not shown) is fixed to the lever (48), while the pawl is manually rotatable from an inactive position to one in which the spring is deflected by the pawl and the latter is held in engagement with the winding train. A separate detentably movable part (50) locks the winding weight.

[Also in Division C6] A vaccine for preventing foot-and-mouth disease Type A comprises a homogenous, non- virulent immunogenic strain of foot-and-mouth virus Type A in a therapeutically acceptable vehicle, the virus being produced by cloning on a baby hamster kidney cell (BHK21) monolayer culture, a heterogeneous Type A strain of the virus which has been modified by about 45 serial passages in chick embryos (e.g. the Kemron egg strain), so as to produce plaques originating from a single virus particle, selecting plaques according to their conformity in size, and further cloning on BHK21 monolayer cultures until homogeneity of plaque size is achieved, and selecting and separating the strain which shows negligible virulence with sufficient immunogenicity on testing. The virus is then propagated in intact animals or chick embryos, primary culture of animal tissue, or a secondary culture of susceptible cells. After removal of cell debris, the harvested liquid may be used as such as a vaccine, or concentrated if necessary, suitably by the method of Specification 1,058,081, or freeze-dried and reconstituted with a buffered glycerol solution containing a virus stabiliser.
