Patent GB-834058-A (GB)
Title: Manufacture of dry batteries
Inventor: NAGORSKI WITOLD
IPC: H01M6/12
Filed: 1957-06-21
Abstract: 834,058. Batteries. BURNDEPT Ltd. Sept. 22, 1958 [June 21, 1957], No. 19624/57. Class 53. Cells of the layer type are made by applying a plastic material 11 in a fluid state to form a lining to a mould 1 having recesses 2 with apertures 3 in their bottom surfaces. Corresponding apertures are made in the lining, and a conductive carbon-loaded plastic sheet 12 is placed in each recess. A depolarizer cake 13 impregnated with electrolyte is then added, and then a coating 16 of methyl cellulose or a sheet of paper coated with methyl cellulose, a zinc sheet 15 and a sheet of conductive plastic 14. The sheets 12, 14 may be omitted. The mould is then covered with liquid plastic 17 which, when set, becomes joined with the plastic lining, thus producing a number of cells each of which is entirely enclosed by plastic material. This is then stripped from the mould and cut up into separate cells which are stacked to form a battery. Fig. 2 shows an apparatus for coating the mould recesses with plastic material and also applying the second coating. The moulds are placed at the position a on an endless belt 5 and are passed under a nozzle 6 from which plastic material is sprayed to coat the flat surfaces of the moulds and the recesses. The moulds are then carried through a heated chamber 8 to set the plastic. At the positions b, c, d, the components of the cells are placed in position and the moulds sprayed a second time by the nozzle 7 to form the plastic covering. An electrostatic field may be applied during the spraying processes to prevent the plastic from bridging across the apertures 3. The sprayed moulds are passed through a second oven 9. In an alternative method the covering 17 is formed by a viscous sheet of plastic issuing from a wide nozzle.

Abstract: 691,977. Lamp holders. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 8, 1950 [Aug. 11, 1949], No. 19700/50. Class 38 (i). A holder for a tubular lamp having a single contact at each end comprises a housing 1 provided with a lamp-receiving opening 2 in which is resiliently mounted an insulating member 6 having a contact 24 which, after insertion of the lamp and rotation thereof in the holder, is engageable with a fixed contact 13 to energize the lamp. The member 6 is cruciform with recesses 25 from two of which the contact 34 extends through the member to provide the semi-circular contacts 22 which are slid into a groove 37 in an insulating mounting 30 for the lamp contact 33 on the end cap 27. The mounting 30 has a groove 38 which is engaged by the edge of the opening 2 when the lamp is rotated less than 60 degrees to switch on the current, thereby preventing the lamp from falling out of the holder. The entry 5 to the opening 2 is dimensioned so that the lamp can only be inserted with the groove 37 vertical. Specifications 691,979 and 691,980 are referred to.

Filed: 1949-07-28
Abstract: 691,174. Brackets. HOBSON, C. W. Oct. 30, 1950 [July 28, 1949], No. 19860/49. Class 52(v) A bracket support comprises a channelled member 13 carrying projecting brackets 12, each bracket adjustably held in position by a bearer comprising a wedging member 15 carrying the bracket at one of its ends and being pivoted at its other end to two spaced wedge blocks or expanding shoes 16. To adjust the bracket it is tilted from its normal position of use and the wedging member 15 is thus withdrawn to allow the wedge blocks to be slid along the channel. When the bracket is at the required height the wedging member is pivoted into engagement between the wedge blocks which lock against the side walls of the channel. The wedging member may be held in position by a spring ball and catch 21, 20 or as shown in Fig. 14 the wedge blocks may be formed with an extension 36 which forms a continuation of the wedging member when it is in the wedging position. The bracket 38, which is detachably mounted on the wedging member 35, slides over the extension, thus locking the wedging member.in position. The outer surfaces of the wedge blocks may be roughened or bonded with rubber and the walls of the channels may be notched or toothed to increase the grip of the wedge blocks on the walls. The wedging member may have a tapering crosssection throughout or may have only a portion of tapered cross-section to engage a protuberance on the wedge block as shown at 18, 19 on Fig. 4. Specifications 20048/04, [Class 52], and 628,537 are referred to.

Abstract: 227,758. Winkley, E. E. Aug. 26, 1924. Golf-practising appliances.- A golf practice or playing apparatus comprises a screen mounted to swing upon a support under the impact of a golf ball and co-operating with a distance register, with or without means for indicating the direction of flight and elevation of the ball. In the form shown in Fig. I a captive ball 69 is teed on a mat 77 and driven through a mesh of resilientlymounted vertical and horizontal strings 49, 71 arranged in front of a canvas screen 9. The screen is pivoted upon adjustable arms 25, and after swing- ing backwards under the impact of the ball is retained by a pawl 3') and rack 41. Graduations on the rack indicate the. distance of the drive. The direction and elevation of the drive are ascertained by observing in which mesh the tether of the ball is retained. After making a stroke, the result may be plotted on a map of the golf course by the aid of the template shown in Fig. 5. The zero 85 of the template is placed on the map over the teeing or playing point, and the central line C is arranged in the direction for a correct stroke. The position of the ball after the drive is then marked on the map through one of the perforations P according to the distance of the drive indicated on the rack 41 and to its deviation as indicated by tabs 59, Fig. 1. The player selects his clubs according to the lie of the ball as indicated on the map. The mat 77 is formed with a hole 79 to receive the ball when playing strokes from the rough. To simulate playing from a bunker or sand trap a wooden block 80, Fig. 6, is placed beneath the mat. The reverse side of the mat is used when playing from the fairway. The device may be used with a free instead of a captive ball.
