Abstract: 664,662. Condensers. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 29, 1949 [Sept. 1, 1948], No. 22387/49. Class 37. [Also in Groups VIII and XV] A machine for affixing a plurality of condenser tap straps to a strip of insulating material which is in continuous motion comprises a friction drive roll 62, Fig. 1, which causes an insulating mounting strip 12 to be drawn continuously through the apparatus from a supply roll 10. A conducting strip 14 of which the tap straps are made is fed transversely across the strip 12 by notched feed rolls 15, 16 and by a disc 25 coacting with a sectorshaped disc 26 which also applies adhesive from a trough 33 to those portions only of strip 14 which are to be affixed to the insulating strip 12. Simultaneously with the interruption of the conducting strip 14 feed, when notches 151, 16<SP>1</SP> are adjacent and in alignment, a holding element 36 and a knife edge 35<SP>1</SP> are moved down by the action of cams 48, 49, the conducting strip 14 being severed and a toggle tamper 55 pressing the previously adhesive coated portion of strip 14 on to the strip 12 as it moves along. A modification illustrated in Fig. 2 (not shown), has cam-actuated interruption of the conducting strip friction roller feed, adjustable speed drive for this strip allowing for different widths of insulating strip which may be fed through from the right or left of the apparatus. Specifications 657,951 and 662,306 are referred to.

Title: Improvements in or relating to web coating apparatus
IPC: B05C11/06
Filed: 1952-09-05
Abstract: 727,602. Coating webs. WALDRON CORPORATION, J. Sept. 5, 1952 [Sept. 7, 1951], No. 22407/52. Class 140. A web W, e.g. of paper, is coated with liquid coating composition, e.g. by a roller 14, and the surplus coating is removed by an air jet from a nozzle 24 which has a slot defined by a pair of converging plates 50 and 52, one of which carries a baffle plate 26 which forms a second slot adjacent the main slot through which a secondary current of air is induced by the flow of high-velocity air through the main slot. The width of both slots is adjustable, and the inner surface of each plate 50 and 52 is convex with the curvature increasing towards the lip. A plate 32 deflects the air stream after it has acted on the web, and a drip pan 34 catches coating material removed by the air blast. The nozzle is pivoted at each end so that it can rock about an axis roughly coinciding with the line of impact of the main air jet, and also about the axis of tubular manifold 44. Adjustable stops limit the amount of rocking movement. Specification 647,886 is referred to.

Title: Improvements in or relating to jewellery and trinkets made from precious or semi-precious stones which, though of pale tint in themselves, are given a vividly tinted andfiery appearance
IPC: A44C17/00
Filed: 1920-07-28
Abstract: 149,634. Paltscho, E. Sept. 18, 1918. [Convention date]. Gems; materials for jewellery.-In articles of jewellery or trinkets set with precious or semiprecious stones of pale tint and thus of poor grade as regards sparkle, a vividly tinted and fiery appearance is given to the stones by backing them with pieces of natural butterfly wings of similar colour. For example, a very pale sapphire is tinted a vivid blue by backing it with the wing of a butterfly having a bright blue colour, and a pale emerald is given a green tint by using the green portion of the wing of the " Urania cronis." The stones are cut and polished in the usual way and the butterfly wings placed beneath them act only through their sheen and colour in conjunction with the light-refractive effects of the stones.

Title: Improvements in or relating to television or like systems
IPC: H04N5/257
Filed: 1933-08-12
Abstract: 424,199. Television transmitters. WILSON, J. C., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. Aug. 12, 1933, No. 22548. [Class 40 (iii)] The image of an object to be transmitted is formed on a luminescent screen scanned by radiation, such as cathode or ultra violet rays, and associated with light-sensitive means to produce the picture signals. The fluorescent screen 4 of a cathode ray tube 5, on which the image 3 of the object 2 is projected, is scanned by a beam of cathode rays of intensity sufficient to produce saturation or approximate saturation of the fluorescent material. The change in the amount of light incident on the photo-electric cells 6, 7, during the movement of the beam is proportional to the change in the luminous intensity of the corresponding elemental areas of the image 3 since the cathode beam sequentially brings each area to, or approximately to, the saturation luminescence. The wave length of the exciting radiation is less than that corresponding to the maximum spectral sensitivity of the cells 6, 7 which may be replaced by a single annular cell combined integrally with the tube or mounted within the tube on the side of the screen 4, on which the electronic beam impinges.

Title: Improvements in and relating to umbrellas
Inventor: HAUPT HANS
IPC: A45B19/04
Filed: 1920-07-29
Abstract: 170,930. Haupt, H. July 29, 1920. Telescopic umbrellas.-A collapsable umbrella comprises a telescopic stick and telescopic ribs. Each rib is maintained in its extended position by a spring 11, Fig. 1, attached to a middle part 7 frictionally engaging a bridge 12 on an upper part 4, and a spring 8 on an outer part 9 engaging a slot in the member 7. A runner 20 seats, when the umbrella is opened, on a cylindrical body 18 attached to a member 21 of a telescopic stick. To telescope the stick, a cap 2, Fig. 4, is depressed, forcing inwards a catch 32, whence a thin end 1 of the stick can be slid into an adjacent member 17. The thin end 1 is pointed, as shown at 33, and thereby releases a catch 34, allowing the members 17, 21 to telescope. The members 27, Fig. 1, can be slid over the member 25 after releasing a catch 26. When its inner end presses against a bevelled catch 24, this is pressed inwards and releases the member 25. A similar action occurs at the catch 22. The ribs are closed by forcibly sliding members 4, 7 together; a cone 10 on the member 4 then engages the spring 8 and presses it inwards, allowing the member 9 to slide within the member 7. A cover 5 is attached to the ribs so that it folds as shown in Fig. 9. The cover and also springs 3, which aid the opening of the ribs, are clamped between plates 16, 31, and a piece of the fabric 15 is gathered over the top 2 so as to exclude dirt from the releasing-device thereunder.

Title: Improvements in or relating to electrically operable indicators
IPC: G08B5/24
Filed: 1938-07-29
Abstract: 517,485. Electric, signalling systems STANDARD TELEPHONES & CABLES, Ltd. (Schreiber, L. J. J., and Lens, G. X.). July 29, 1938, No. 22636. [Class 40 (i)] An electrically operable indicator comprises a number of separately operable indicating members, common electromagnetic stepping means for setting said indicators in turn, electromagnetic sequence equipment operated in each interdigital period to transfer completely the drive of the stepping means to the next indicating member before the impulse of the succeeding digit is received, and electromagnetic means arranged simultaneously to house the indicator members the three electromagnetic functions being performed by two electromagnets only. Upon the stepping magnet 16, Fig. 1, receiving a pulse, its armature 17 is raised, lifting the frame 18, running the length of the indicator, and consequently the pin 10 associated with the first digit wheel 1. The arm 9, carrying the blocking and stepping pawls 6, 7 is retracted so that upon magnet 17 being de-energized, the wheel 1 is stepped round. Upon the first train of impulses ceasing, the transfer magnet 19 is energized the armature 20 being prevented from making a full stroke due. to bracket 25 engaging lug 26. Pawl 21 engages in the next tooth of ratchet wheel 22, the spindle 15 being rotated when armature 20 falls away the cam 14 releasing arm 11, whereupon the pin 10 is retracted from frame 18 and the cam associated with the next digit wheel causes the corresponding pin to be inserted in the frame. The next train of impulses to magnet. 16 steps on this wheel, the process being continued until the last digit wheel is set. In order to zeroize the apparatus, both magnets are energized, the armature 20 now making a full stroke, pins 29 releasing the holding pawls 5, while pins 30 raise the pawl lever 9 so that the blocking pawl 6 frees the ratchet 2. At the same time, the stepping pawl 7 is brought up against a fixed stop 31 and the digit wheels are spring returned by the aid of gear wheels 33 and sector 3. The pawl 21 is displaced by the stop 27 causing holding pawl 23 to release, whereupon cam shaft 15 is returned to normal by spring 24. In order to give idle or busy signals, a spring contact pile-up, Figs. 4, 5, is arranged between the magnets 16, 19. This consists of an arm 51 carried by a spring 50 and arranged between contact springs having contacts 53 co-operating with contacts 49 on a central spring 48. When the indicator is displaying a subscriber's number, the pile-up is as shown, but when both magnets are energized to zeroize the indicator, the armature 20 displaces the arm 51 which engages behind the tooth 55, and when the magnets release, the arm is held behind tooth 56, causing the left contacts to close. Upon the first operation of magnet 16 the arm releases to the position shown.

Title: Improvements in or relating to zinc cadmium phosphate compositions or phosphors
IPC: C09K11/70
Filed: 1953-08-17
Abstract: Manganese activated zinc cadmium phosphate of general formula:-xZn0.yCd0zP205.mMn0. where x / y is from 1/20th to 20, <FORM:0744861/III/1> is from 2 to 4, and <FORM:0744861/III/2> is from 0.001 to 0.2, is prepared by mixing zinc oxide, cadmium carbonate, manganous carbonate and phosphoric acid or an ammonium phosphate drying the mixture, pulverising and screening and calcining at from 600 DEG C. to the melting point.  The zinc oxide may be replaced by the carbonate or hydroxide; the cadmium carbonate may be replaced by the oxide or hydroxide and the manganese carbonate may be replaced by the nitrate, phosphate sulphate or manganous oxide.  According to Example (III) zinc oxide dissolved in nitric acid is added at 70 DEG C., to a solution at the same temperature of diammonium hydrogen phosphate, the mixture is cooled and the precipitate after filtration is washed and dried to yield zinc phosphate.  Cadmium and manganese phosphate may be similarly prepared; zinc cadmium phosphate activated with manganese may be made by heating a mixture of the phosphates so prepared at 900 DEG C.  In the preparation of the individual phosphates any soluble orthophosphate or phosphoric acid may replace the diammonium hydrogen phosphate and the latter may be employed as an ammonial solution.  Orthophosphates are yielded if the precipitation is carried out under acid conditions or double ammonium orthophosphates are precipitated if the precipitant is ammoniacal, which double phosphates may be converted by calcination to pyrophosphates.  The activated zinc cadmium phosphates are employed as phosphors (see Group XL(a)). Specification 512,154 [Group XL], is referred to.

Filed: 1933-08-14
Abstract: 422,282. Moulding soap. JONES, R. A., 15th Street, Covington, Kentucky, U.S.A. Aug. 14, 1933, No. 22692. [Class 87 (ii)] Crude blocks of soap are shaped and, if required, embossed, in a press comprising a frame 11 having at its lower end a mouldcarrying shaft 25, Fig. 6, which is intermittently rotated through Geneva stop mechanism 21, 23 actuated by a driving shaft 12. The main part of the shaft 25 is square and carries two moulds 27 on each of its faces, a die 31 being located in each mould. Two pairs of oppositely positioned dies are coupled by rods 32, the other two pairs being coupled by rods 33. The crude blocks are advanced along a guide by a conveyer 65, Fig. 4, the end blocks passing on to a plate 84 through which works a vertically guided plunger 89 to elevate the end block into alignment with a plunger 102, this latter transferring the block into the opposed mould and simultaneously effecting the discharge of a moulded block from the opposite die. The plunger 102 is yieldingly driven by a link 118 and lever 119 which is loose on the shaft 120 but is coupled to an arm 124 fast thereon, by a rod 126 and spring-pressed washer 130. The operative face of the plunger 102 is grooved to minimize adhesion to the soap, and pawls are fitted in the channel 83 to permit only of one way movement of the blocks. On rotation of the mould shaft the filled moulds are positioned beneath a die 40 which is yieldingly mounted by a collar 64 and spring 63 in a press member actuated by levers on an overhead rockshaft. After the soap has been shaped by the die, the mould shaft is rotated and on the next mouldchanging operation the pressed block is ejected into a frame 138 of similar shape, at the same time discharging the block previously located in the frame on to a conveyer 140. The frame 138 is provided with yielding block-retaining pins, and is carried by an arm 137 which is rocked through a small angle by linkage actuated by the shaft 120. The conveyer 140 is driven by chain and skew gearing 143, 147, Fig. 1, and the various shafts are intergeared to effect synchronized operation of the mechanisms.

Patent GB-810796-A (GB)
Title: Improvements in or relating to a machine for packing containers into cases
IPC: B65B5/06
Filed: 1956-07-25
Abstract: 810,796. Packaging. EMHART MANUFACTURING CO. July 25, 1956 [Aug. 15, 1955], No. 23046/56. Class 94(1). In a machine for packing containers, e.g. milk cartons 6 of uniform square or rectangular cross-section, in cases 50, four rows of cartons 6 are fed into the machine by a conveyer 5 and over a dead plate 7 with the rows at different levels onto a trap door 26, 27. When the leading cartons have crossed the trap door, the tops of all the cartons are gripped, the trap door opens and the cartons are lowered into an empty case 50 on a conveyer 49. The conveyer 5 delivers the cartons over the dead plate 7 which is formed at two levels by the sections 12, 15, Fig. 7, so that the two outer rows of cartons drop slightly in passing over this plate as shown in Fig. 8. The trap door has two sections 26, 27, the rear section 26 being formed by four horizontal fingers 22a projecting through notches 18 in the dead plate 7 and on the same level as the raised section 12 and four other fingers 25a projecting through notches 17 in the dead plate and on the same level as the lower sections 15, all these fingers being fixed to a shaft 23. The other half of the trap door is composed of similar fingers 30a, 31a, on a shaft 28. When the front carton of each row has been pushed by the succeeding cartons over the trap door, it strikes a detector 36 and when all the detectors 36 have been struck, mechanism is operated whereby gripper fingers 71R, 71L, 73R, 73L, engage grooves 71 around the cartons, as shown in Fig. 8. The gripper fingers are attached to a head 58, composed of three sections 58a, 58b, 58c, Fig. 1, and this is operated by an air motor 61. When the gripper fingers engage the cartons, the movement of conveyer 5 is interrupted and an empty case 50 on conveyer 49 moves into position under the trap door 26, 27, is stopped by a fixed stop 51 and actuates a detector 52 so lowering head 58 and the gripper fingers. The movement of the head causes the trap door 26, 27 to swing open and the cartons drop through a funnel 106 into the empty case 50 as shown in Fig. 6. The funnel is lowered slightly during this operation in order to align itself in the mouth of the case 50 and thus guide the cartons into it. When this has happened, a cam strip 139, on the head 58, Fig. 1, actuates another detector, thus causing release of the gripper fingers, raising of the funnel and gripper head and closing of the trap door. When the head is near the top of its journey it contacts another detector which operates a case kicker 54, thus projecting the filled case past the fixed stop 51 and also restarts the conveyer 5. The whole cycle then begins again. The machine is pneumatically operated and may have electrical or mechanical controls to operate it in the correct sequence. Specification 810,795 is referred to.
