Title: Improvements in and relating to golf tees and method of making the same
IPC: B29C49/00
Filed: 1929-09-03
Abstract: 334,707. Burri, A. A. Sept. 3, 1929. Moulding celluloid; golf tees.-Golf tees formed of celluloid &c. and adapted to be nested together as in Fig. 9, are made by superimposing two sheets of celluloid &c. in a mould comprising' halves 1, 2 provided with flanged meeting faces 3<x>, 4<x>. The mould halves, registered by dowels 10 are placed under light pressure by a press head and hot fluid, e.g. steam, air or liquids, is introduced between the sheets of celluloid through an orifice 9, thereby expanding the celluloid to the mould form. Heavier pressure is then applied to the press head to sever the sheets at the inner periphery of the mould and to fuse together the meeting portions of the celluloid half tees. Internal pressure is released, the mould opened and the double-tee is cut across its central transverse section to form two similar hollow tees. The mould may be arranged to form a single tee at each operation, in which case the internal fluid pressure is introduced axially at the large end of the mould shape.

Title: Improvements in or relating to paper base planographic printing plates
IPC: B41N3/03
Filed: 1947-10-08
Abstract: 633,796. Printing-surfaces. WARREN CO., S. D. Oct. 8, 1947, No. 27025. Convention date, June 30. [Class 100 (ii)] A planographic printing-surface as described in Specification 633,747 is modified by using a single coating of a hydrophilic material to which is added the water-soluble salt of a di-valent metal. The paper base may be an ordinary coated paper stock, which is modified to have a stronger resistance to water where long runs of printing are required. The single coating comprises a pigment or filler such as clay, or blanc fixe, an organic hydrophilic adhesive such as casein or glue, and a solution of a di-valent metal salt. Instead of including the salt in the coating it may be applied in liquid form to the coated paper, and dried off. The amount of salt added to the coating is in excess of that which reacts with the hydrophilic adhesive. Example: 22 parts of copper chloride were dissolved in 38 parts of water, and a concentrated solution of ammonia added which first precipitated copper hydroxide and then dissolved it. This solution was stirred into an ammoniacal solution of casein containing 22 parts casein in 90 parts total. The whole was then added to 100 parts of clay in water, making a mixture with solid contents of 35 per cent. The mixture was applied to the paper base, dried and calendered. Zinc chloride may replace the copper chloride, and similar coatings may be made from sulphates, acetates, and nitrates of other metals. In place of casein, animal glue, soy protein, polyvinyl alcohol; starch, gum arabic, zein, or albumin may be used, or mixtures of these with addition of other hydrophilic colloids. As an example of applying the salt in solution, a wet-strength paper was coated with 100 parts of clay and 18 parts of casein dissolved in ammonia, and after drying and calendering was treated with a 16 per cent solution of zinc chloride in ammonia. Lead acetate may replace the zinc chloride. In all cases the printing-plate may be treated by the rubbing process described in Specification 633,746.

Title: Improvements in or relating to vehicle driving arrangements
Inventor: EVERNDEN HAROLD IVAN FREDERICK
IPC: F16H47/08
Filed: 1952-10-28
Abstract: 784,119. Change-speed differential gearing. ROLLS ROYCE, Ltd. Jan. 20, 1954 [Oct. 28, 1952], No. 27121/52. Class 80 (2). A driving arrangement for track-laying vehicles comprises a hydro-kinetic unit (e.g. a fluid-coupling 14) interconnecting a power input shaft 11 and a cross-drive shaft 25, the torque being transmitted partly by the coupling 14 and partly by a hollow primary cross-shaft 13 on which the impeller 15 is mounted. This construction is compact and light and allows spur gears 23, 24 to be secured to either end of a further hollow shaft 22, which is inside the primary shaft 13 and driven through an epicyclic gear 16, 19, 20. The cross-drive shaft is driven by one of the spur gears 23, 24 through one of three epicyclic gears 31, 39, 47, providing four forward and one reverse speeds, brakes 33, 41, 48 and clutches 34, 42 providing changespeed means. The track driving sprockets (not shown) are secured to shafts 10 which are driven by the cross-drive shaft 25 through epicyclic gears 50 and by a differential gear, the cage 54 of which is formed integrally with the hollow shaft 22. The drive through the differential gear is negative and normally takes speed off the main drive, so that by applying a brake 66 to stop the shaft 25, a very low reverse speed is obtained. Alternatively the speeds may be arranged to add. Normally equal torque is transmitted to the shafts 10 and track sprockets, but brakes 65 vary this to provide steering control. In one modification, Fig. 2, a torque converter 70 replaces the fluid coupling. This converter 70 comprises a pump element 71 rotating with the primary cross-shaft 13, a turbine element 72 driving in part the spur gear 23 through epicyclic gearing and a two-part stator section 74, 75. Each part of this stator section drives a sleeve 76 through a free-wheel device 77 or 78 when a brake 79 is released and a clutch 80 engaged to allow the converter to function as a fluid coupling, for the higher reduction ratios. By engaging a clutch 81, the pump and turbine elements are locked to give a direct drive. In a second modification, Fig. 3, an additional epicyclic gear 92 on the cross-drive shaft 25 provides a fifth forward speed. Specification 607,120 is referred to.

Abstract: 1506759 Frame detection WESTERN ELECTRIC CO Inc 27 June 1975 [1 July 1974] 27236/75 Heading H4M For a multiplex system wherein a plurality of digital groups, 1-5, Fig. 4; each comprising a plurality of t.d.m. channels 0-23; are themselves time multiplexed on to a common transmission link 28, each digital group including a framing bit, the framing bits forming a pattern (D9 1 -D9 5 ), Fig. 5 (not shown), there is provided a framing pattern detector 20, Fig. 2, wherein shift registers 33 store in a column of bit positions corresponding to the groups, expected timings for the framing bits in terms of the states of signals (EF, FP 1, Fig. 5), such expected timings being recirculated in synchronism with the presence of groups on link 28, and updated according to the group multiplexing scheme by logic 34, the expected timing of a group currently on the link being compared in checker 35 with the actual framing bit timing, any disparity leading to the production of error signal E. For each group, a corresponding column of bit positions of recirculating shift registers 37 stores an accumulated error number, for each frame increased by 7 for a given group upon production of an error signal for the group, otherwise being decreased by one, a signal T max for the given group being emitted should the group error number exceed 15. The signal T max causes a bit position, corresponding to the given group, of recirculating shift register 41 to change to an "outof-frame" state, a resulting signal being sent to reframer 30, the latter causing interruption of address shifting in the reading of the given group into multiplexer (27), Fig. 1 (not shown) until the "in-frame" status for the given group is regained. The recirculating registers have an extra (sixth) bit position which is associated with 8 spare bits SP, regarded in the framing pattern detector as a further (sixth) digital group, which may be used for in-service testing. Group multiplexing arrangement Fig. 1 (not shown).-Each channel slot of each group comprises an eight bit data word, D1-D8, framing bit D9, and parity digit P, words being written, alternately, into A and B stores, in parallel format, at a data rate determined by recovering the data rate on the input line (11). The data words are read out in parallel to be multiplexed in parallel format on link 28, at a multiplexing clock rate, slip control (26) ensuring that a given frame may be read out twice, or a frame reading omitted, in dependence on any disparity between the recovered data rate on line 11, and the multiplexing data rate.
