Abstract: 942,413. Ornamenting. LONDON RUBBER CO. Ltd. June 26, 1962 [July 6, 1961], No. 24489/61. Heading B6G.  Flock is applied to the surface of articles which have been previously coated with an adhesive by passing said articles through a flock-application chamber having an opening or openings in its walls communicating with the surrounding atmosphere, directing a stream of flock-laden air against the surfaces of the articles and simultaneously extracting air from said chamber at such a rate as to maintain a continuous flow of air into said chamber through said openings, the extracted air being passed through flock-extraction means. As shown (Fig. 1) a flockapplication chamber 10 is formed as a box-like structure with slots 11 extending along one side wall and partially along both end walls so that articles such as gloves 12 mounted on formers may extend into the chamber whilst being moved on a conveyer past the flock-application chamber. The formers may be rotated. The upper and lower ends of the chamber taper towards outlets 14, 15 merging into a single duct 17 leading to a cyclone separator 18 in which flock is separated from flock-laden air drawn out of chamber 10. The air from the cyclone separator is passed through bag filters 23, the air outlets of which lead to an extraction fan (not shown). The filters may be brought into alternate use by slide dampers 27 and 28. The separated flock falls into hoppers 19 beneath the cyclone separator and 20 beneath the filters, from which it is drawn by a fan 34 and re-used. A flock make-up reservoir 35 is also provided. The flock-laden air is blown into chamber 10 through nozzles 45 mounted on the ends of horizontal tubes 46 arranged between the rows of articles to be coated, the nozzles being fitted with deflector plates 47. Pneumatic cylinders enable the nozzles to be moved to and fro within the chamber. The extraction fan draws air out of the chamber at such a rate that there is a continuous inflow of air through slots 11 so that any flock not adhering to the articles is drawn into ducts 14-15 and does not escape into the surrounding atmosphere. Modifications in which the chamber is formed as an openended tunnel and in which groups of nozzles are used are described.

Title: Improvements in and relating to brake systems and apparatus for railway vehicles and the like
IPC: B60T15/38
Filed: 1922-09-13
Abstract: 208,221. Glascodine, R. T., Mc- Dermid, W. F., and Spencer, A. Sept. 13, 1922. Fluid-pressure brake systems of the automatic type are provided with subsidiary reservoirs which are connected to the brake cylinders in an application of the brakes for moving the brake pistons to the end of their stroke so as to avoid the use of the auxiliary reservoir air for this purpose. The subsidiary reservoirs are cut off when the brake cylinder pressure reaches a predetermined value. Fig. 9 shows the application to the combined Westinghouse and vacuum system described in Specification 190,518. The subsidiary reservoir 7 is connected through the pressure controlled cut-off valve 5 to a passage 2 in the triple valve 1 whereby in the release position the reservoir 7 is connected to the chamber of the valve 1 by the port 12 in the slide valve 11 and thus to the auxiliary reservoir 13 and the trainpipe in the usual way. The valve 5 comprises a piston 16, Fig. 8, open on its upper face to the atmosphere by port 20 and on its lower face to the brake cylinder 10 by passage 8 and pipe 9 so that normally this piston under the influence of a spring 15 holds open by a stem 17 a valve 14 by which and the passages 6, 4 and pipe 3 the subsidiary reservoir 7 communicates with the triple valve 1. Upon an application of the brakes, air from the subsidiary reservoir 7 passes to the brake cylinder through a channel in the slide valve 11, for instance, the exhaust cavity 22. The brake piston having thus been moved to the end of its stroke, the brake cylinder pressure rises to a sufficient degree to move upwardly the piston 16 of the valve 5 and permit the valve 14 to close under the action of the spring 24 so that any further pressure in the brake cylinder is provided by the auxiliary reservoir air. Ports 21 provided in the piston 16 serve as additional exhaust ports from the brake cylinder chamber of the valve 5 after the piston 16 has been moved away from its seating 23 during the release of the brakes.

Filed: 1926-04-26
Abstract: 265,137. Burroughs Adding Machine Co., (Assignees of Horton, A. A.). Jan. 29, 1926, [Convention date]. Adding-apparatus with printing mechanism.- In a machine wherein the differentially movable members transmit their movement to the totalizer actuating elements and type bars the shock due to the sndden stopping of the differential members by the depressed key stems is prevented from being transmitted to the type bars by a cushioning recess interposed in the connection between the said members and type bars. As shown in Figs. 1, 2 and 3 applied to a machine of the type described in Specification 265,122, a number of bars 233 with differentially positioned stops 252 co-operating with the key stems 11 are slidably mounted at their front ends in a comb plate 232 and at their rear ends are connected through cushioning means to the arm 234 oi the actuating rack elements 235 to which are attached the vertically movable type bars 264. Each arm 234 carries a pin 239 engaging an elongated slot 241 in the corresponding bar 233 and a connecting member 243 has a recess 249 for engaging a groove in the pin 239. The member 243 has an extension 244 to which is attached one end of the control spring 250 and is provided with projections 245, 246 engaging the side and bottom of the bar 233, a shoulder 247 being provided on the projection 246 to engage a notch 248 in a projection on the bar 233. During the forward strode of the handle the cam 73 on the main shaft 71 through a roller 260 raises the bail 255 and the springs 250 move the bars 233 until they are arrested by the stems of the depressed keys. When a bar 233 is thus suddenly stopped the pin 239 moves in the slot 241 and in so doing rotates the connecting member 243 counterclockwise against the tension of the spring 250 which thus takes up the shock. By reason of the disposition of the parts the springs 250 serve to counterbalance the weight of the bars 233 and reduce friction on the comb 232. In Figs. 4 and 6 is shown the arrangement of the cushioning device associated with the bank of control keys and special character type bar 264. The positioning device for the type bar comprises a stepped plate 358 and an arm 354. the arm being integral with a yoke 352 and slotted arm 353. A pin 355 on the toothed segment 351 carrying the character type bar engages the slot in the arm 353 and a groove in the pin engages a slot 356<a> in a member 356 similar to the member 243. Sudden stopping of the arm 354 allows the pin 355 to move in the slot of the arm 353 and thus tension the spring 357. Specification 235,136. [Class 40 (iv), Telephones &c.], is also referred to.
