Patent GB-718005-A (GB)
Title: Improvements in and relating to crack-off devices for removing excess exhaust tube from lamps, radio tubes and the like
IPC: H01K3/00
Filed: 1952-10-28
Abstract: 718,005. Making electric lamps &c. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 28, 1952, [Oct. 30, 1951.] No. 27071/52. Class 39 (2). Apparatus for cracking off the excess end portion of a vitreous exhaust tube extending from a mount for an electric lamp, radio tube, or the like, comprises a mount holder 12, Fig. 3, with a portion 15 arranged to provide a rest for the flared stem tube 5 of an inverted mount 3 and a second portion 39 spaced above the portion 15, so that when the holder is moved and carries a mount laterally to bring a notched or scored portion of its exhausting tube 4, Fig. 2, against a stationary stop finger 38, the mount is first tilted in its holder so that the flare 11 of the stem tube is engaged and restrained by the portion 39 of the holder, whereupon further movement of the holder relative to the stop finger 38 produces a strain in the exhaust tube sufficient to break it at the notch 10. Fig. 1 shows a part of the conveyer 1 of mount-making apparatus of the kind disclosed in Specification 564,702, [Group XL], and comprising work stations A and B located adjacent to another conveyer 2 of the endless chain type provided with a series of work holders 12 and pairs of jaws 13, 14 which take over the inverted mounts and grip the exhaust tube 4 thereof after the latter has been scored in passing a sharp edged metal disc 7 driven by a high speed motor 9 located adjacent to the work station A. The conveyer 2 is mounted upon a support which is reciprocated bodily to and from a position adjacent to work station B, the timing being such that a mount is released from conveyer 1 when a work holder of conveyer 2 is positioned to receive it. In the following bodily movement of conveyer 2 away from work station B a pivoted pawl-carrying arm 20 is operated by a link 23 to turn a shaft 19 carrying the chain-driving sprocket 16, whereby the work-carrying heads 12 are indexed one step with the chain 18 and an empty head 12 is advanced to the receiving position. The two straight runs of the conveyer chain are guided by rails 24, 25 on opposite sides of each run, so that the inward parts of the flare supports 15 slide along the rails, Fig. 3. The breaking or cracking-off operation is effected when a head carrying a mount arrives at station C at the end of the conveyer remote from the loading station B, so that bodily movement of the conveyer towards the left causes the upper end of the exhaust tube 4 to strike the stop finger 38 and break at the scored or notched part 10. To prevent the mount from being jarred out of the holder 12 by the impact, a stationary guard 44 is mounted adjacent to the stem tube. The abutment finger 38 is mounted on a hinge pin 45 near the end of a rigid supporting arm 46 and normally rests on the end portion 47 of the arm; alternatively it may be rendered inoperative by tilting it rearwardly upon the arm 46.
Patent GB-627581-A (GB)
Title: Improvements in apparatus for preheating slurry
IPC: F26B11/04
Filed: 1946-09-10
Abstract: A preheater for cement and like slurry comprises a rotatable tube in which is disposed a compartment containing a charge of loose bodies and having walls provided with openings through which slurry and hot gases pass in contact with the loose bodies, the compartment being arranged with its walls extending axially across the interior of the tube.  As shown, Fig. 1, a compartment 1 is disposed within a rotating tube 4, through which hot gases pass from chamber 11 to exit 13, and into which slurry is fed from pipe 14 to pass out at exit 16. The compartment is supported by trans-verse <PICT:0627581/III/1> <PICT:0627581/III/2> partitions 2, 3 which separate spaces 9 and 10 in the tube and oblige the hot gases and the slurry to pass through the compartment via openings 18, 19 in its walls.  Inperforate sections of the compartment may project through the walls of the tube, which may be divided in the middle by a partition and, to avoid too violent a movement of the loose bodies, the walls may be curved, Fig. 7.  More than one compartment may be disposed within the tube. The preheater may be incorporated in a rotary kiln towards the slurry inlet, and is so dimensioned as to reduce the moisture content of the slurry by only a few per cent (to avoid blocking) and to raise the slurry temperature from 20 DEG  to 70 DEG  C.

Title: Improvements in or relating to bevel wheel gears
IPC: F16H1/20
Filed: 1928-09-22
Abstract: 298,228. Stoeckicht, W. Oct. 7, 1927, [Convention date]. Toothed gearing.-In epicyclic toothed gearing of the kind in which bevel gears a on aligned shafts W1, W2 are engaged by planetary pinions b, the pinions are retained in position by rings c, d secured on the gears, as described in Specification 287,423, the rings permitting the pinions, which are carried on studs f on a floating carrier g, to adjust themselves to provide for uniform distribution of the tooth pressures. The use of both the rings c and the rings d is desirable where the bevel wheels have inclined or arcuate teeth, but the rings c alone are sufficient when the teeth are straight. The wheels a may differ in size.

Film drive (31) and deflection (vertical 30, horizontal 32) circuits are controlled by the output of 28. The cathode-ray tube has an electrode construction similar to that of the Trinitron (Registered Trade Mark) colour tube except that the electrostatic deflection plates are used to establish the centre points a and b and not converge the beams to one point.
Patent GB-1006114-A (GB)
IPC: G03G17/02
Filed: 1961-07-28
Abstract: An imagewise cathodic deposit of a porous hydroxide or hydrated oxide of one or more of the metals Cr, Fe, Co, Ni, and optionally Al, Ce, Mg, Mn, Mo, is formed from an electrolyte solution of a soluble salt of one or more of these metals on an exposed photoconductive zinc oxide in resin layer or a contacting layer coated or impregnated with the electrolyte (see Division G2). Preferably the electrolyte has a concentration of 0.25-3.0% of the metal salts and a voltage of 20-80 volts is applied between the conductive support of the zinc oxide layer and a second electrode separated from the layer by electrolyte. If a porous deposit free from deposited metal is required the applied voltage must exceed 30 volts.  Examples are given of electrolyte solutions containing salts of cobalt and manganese and optionally silver; salts of iron and manganese; chrome alum; and of iron or nickel with organic reducing agents.  The deposit may contain or be treated subsequently with alkaline or other reactive material and used as the starting point in the production of coloured or colloid relief direct or transfer images or printing surfaces (see Division G2).
