Title: Improvements in or relating to photoelectric cells
IPC: H01J40/04
Filed: 1941-05-21
Abstract: 576,414. Photo electric cells. ELECTRICAL RESEARCH PRODUCTS, Inc. May 21, 1941, No. 6517. Convention date, May 25, 1940. [Class 39 (i)] In photo-electric cells, the cathode 9 is sensitized by caesium evaporated from a mixture contained in a cup 18, and a mica disc 10 is interposed between the cup and the cathode to protect the latter from direct contact with the hot'vapour, and a mica disc 21 is provided to protect the adjacent end 6 of the container from the heat of the reaction. The disc 10 is connected to the cathode by a hollow rivet 12 which is covered by a strip 13 of metal, acting also as a lead to the cathode from one of the rods 14 supporting the disc. The cup is supported by a rod 20 welded thereto and to other rods 15 supporting the disc 10, and supports the disc 21 by means of staples 22. The anode 24 is an annulus supported by rods 25 passing with clearance through holes in the mica discs to avoid short-circuiting by deposited caesium. The cathode may be of silver, or copper with silver plating, or a bimetallic sheet of nickel and silver. After outgassing, it is oxidised by successive discharges in an oxygen atmosphere followed by heating to reduce the silver oxide. The sensitization is effected by means such as described in Specification 503,738. The mica discs are rendered opaque to heat by pre-firing in hydrogen at about 1000‹ C. and subsequently compressing to its original thickness. Argon or other gases may be used as, low-pressure fillings.
Patent GB-397876-A (GB)
Title: Improvements in or relating to hand-operated machines for casting stereotype plates
IPC: B41D3/00
Filed: 1933-03-03
Abstract: 397,876. Casting stereotype. MASCHINENFABRIK AUGSBURGNœRNBERG AKT.-GES., 7, Stadtbachstrasse, Augsburg, Germany. March 3, 1933, No. 6568. Convention date, March 3, 1932. [Class 100 (ii).] A stereotype casting-machine, of the kind in which the melting-pot and mould are adapted to be moved from a position of rest to the casting-position where the cast plate is subjected to the pressure of the contents of the pot, is arranged so that the pot and mould are connected by a conduit which is heated so that when they are swung back to rest position, the molten metal can return to the pot. The pot 1 is mounted between side-plates 4 pivoted on a shaft 5 and is secured by screws 8 to the core 7 of the mould which is also carried bv the plates 4. The back 10 of the mould is pivoted on a shaft 11 supported by the plates 4, and is under the influence of a counterweight 12 which tends to hold it in either open or closed position. The back is adapted to be locked to the core by hooks 27 on the back and rollers 28 on the core, the hooks being under the control of levers 37 which also carry stops 38 co-operating with a shaft 36 to retain levers 35 against movement when the mould is closed. These levers 35 are connected by links 39 to a matrix clip 22 which is therefore locked in place when the core and back are locked together. The upper part of the clip 22 is formed with a projection which extends into the conduit 29 between the pot and mould so that the riser is cast round the projection on the clip. The conduit is of greater crosssection at the end adjacent the mould and the narrower end is heated by elements 31 in order to maintain any metal at this point in molten condition. A locking-plate 17 is pivoted on the shaft 11 and is formed with a slot 18 engaging a stop-pin 19, the slot being also formed with a locking-recess 20 at one end. In use, the matrix is locked in place in the open mould, and, by means of a handle 24, the back is moved into closed position and locked by means of the levers 37, this action also locking the matrix clip in position. The plate 17 is rocked to release the recess 20 from the pin 19, and the pot, mould, and counterweight are then rocked into casting-position. After the plate has cooled, the parts are returned to original position, the pot being locked by the plate 17. Faces 40 on the hooks 27 engage the rollers 28 when the mould is being unlocked, so that the back is forced away from the core, and, due to the engagement of the projection on the matrix clip, the solidified part of the riser is also withdrawn from the conduit 29. After the mould has been unlocked and the back opened, the matrix clip can be withdrawn and the cast plate removed.

Title: Improved method and apparatus for directing and grouping a number of individual threads
IPC: D01D10/04
Filed: 1954-03-09
Abstract: <PICT:0753615/IV(a)/1> <PICT:0753615/IV(a)/2> <PICT:0753615/IV(a)/3> <PICT:0753615/IV(a)/4> <PICT:0753615/IV(a)/5> A series of spun threads emerging fro separate and parallel discharge points are discharged into a transverse stream of liquid which carries all the threads to a place beyond the last of the discharge points, where they are drawnoff.  After spinning-in and drawing off the resultant warp, the running threads may be separated and placed between individual guides above and clear of the liquid stream.  Fig. 1 shows a plant for producing 72 threads, each of which passes through a group of tubes 11 containing treating liquid, as described in Specification 686,339, and emerges from one of the inclined delivery tubes 17 into the trough 16, which also receives the treating liquid issuing from tubes 17. As shown in Figs. 2 and 3, liquid is discharged into one end of trough 16 from pipe 24 and carries all the threads down the trough.  The trough 16 gets wider and deeper towards the discharge end, where the threads are drawn off in warp form and pass to drying rollers 48.  To prevent entanglement of the threads in the tough 16 during spinning-in, it is arranged that the threads follow parallel paths in side-by-side formation.  This is achieved by making the delivery tubes 17 of progressively shorter lengths so that successive threads are laid in the trough side-by-side. This is illustrated in Fig. 2, which shows ten delivery tubes 17 laying ten threads side-by-side in the trough 16, which gets progressively wider.  When the threads are all spun in and being drawn off in warp form, the running threads are lifted out of the trough and placed in comb guides 29 which are detachably mounted across the trough at intervals, after every sixth delivery tube 17.  The first comb guide, which accommodates 6 threads only, is shown in Figs. 7 and 8.  It comprises a tube 35 detachably mounted in brackets 31, 33 across the trough 16.  At one end a series of vertical guide-rods 38 are fixed in the tube, one thread passing between each pair of adjacent rods, and rest on a tubular support 39, fixed at its ends by clips 42, 43 to tube 35.  Successive comb guides are similar in construction except that the number of guide rods increases by increments of 6 until the last guide-rod accommodates all 72 threads.  In operation, the first comb guide is lifted from its mounting bracket, the first six running threads are manually lifted out of the trough, the comb guide is inserted under them, each thread is positioned and the comb guide is replaced in its brackets.  This is repeated with the second guide, which accommodates twelve threads, and so on until all threads are running clear of the trough.
