Title: Improvements in or relating to balers
Inventor: MURRAY PATRICK ANTHONY MOLTENO
IPC: A01F15/14
Filed: 1967-08-25
Abstract: 1,244,303. Hay balers. P. A. M. MURRAY, and D. CRAIG. 21 Aug., 1968 [25 Aug., 1967], No. 7203/71. Divided out of 1,244,302. Heading B5F. A pick-up baler comprises a backwardly sloping wheeled chamber provided at its rear end with a normally closed tail gate 3 and at its forward end with a packing plate 6 reciprocated by beams 18 and 23 pivoted to rotatable arms 17. Material picked up by rotary tines mounted at the forward end of the chamber is fed upwardly into the chmber in small discrete amounts by orbitally reciprocated packing fingers 14 carried by arms 17. The charges are directed into the chamber along a feed passage defined by a fixed curved panel 11 and a series of strips 12 depending from the plate 6. In operation, as each charge is forwarded into the chamber through opening 13 it is compressed by strips 12 and is moved upwardly toward the top of the chamber by the action of the succeeding charge and by the plate 6 which has a small upward component of movement. A series of vertical stacks of charges is thus built up in the chamber and the bale as it increases in size moves backwards against the pressure of twine 44 and sprung members carried by the walls of the chamber. When the chamber has been filled the twine is knotted across the feed opening 13 by a knotter unit located at X, the twine being fed to the knotter by needles 29 which reciprocate across the feed opening. Retraction of the twine needles 29 actuates a trigger 57 which releases catch 51 to allow the gate 3 to partially open under its spring biasing. As the next bale is built up, the preceding bale is forced partially out of the chamber, thus fully opening the gate and allowing the bale to be removed. After removal of the bale the gate swings shut and is latched in position whilst the rest of the succeeding bale is formed.

Abstract: 255,133. Baber, W. M. C., and Ayres, Ltd., F. H. March 17, 1925. Handles; golf and like clubs; rackets; projecting &c. appliances.-A wood substitute particularly applicable in the manufacture tennis rackets, crosses, hockey sticks, and the like, is made by laying together a series of fibres previously or subsequently treated with a binder and moulding under pressure and, if necessary, heat, the feature of the invention being the laying of some or all of the fibres under tension. Suitable binders are resinous or phenolic condensation products, balata, rubber, gutta-percha, cellulose acetate gums, resin glue, casein, or the substance known under the registered Trade Mark " Synthite." In an example, a rod of rectangular cross-section is made by winding a yarn of ramie fibre impregnated with synthite solution over distance pieces between two side plates. The winding may take the form of longitudinal layers, or these may be alternated with spirally wound layers, or the laps may be alternately right and left handed helices. When sufficient yarn is laid, front and back plates are applied and the whole is baked to liquify and set the binder. The distance pieces, cores, &c. may be of the same material, and remain in the finished article. Tennis racket frames are made by winding yarn in a channel mould round pins to form stringing holes. The yarn may be laid loosely and tensioned by forcing it into the mould by curved plates.

Title: Improvements in or relating to warning signals for vehicles
IPC: B60Q1/44
Filed: 1928-03-12
Abstract: 287,061. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). March 12, 1927, [Convention date]. Road-traffic signals on vehicles.-Slowing down and stopping signals are given by an electromagnetic relay operated by the brake or driving lever of a tramcar, &c. in which the relay is retained in its position during braking and stopping by a lever locking device electromagnetically released on starting. The switch arm l is rigidly connected with the brake-lever a and its contact f co-operates with contacts g, m so as to close the circuit of the battery b either through the relay h or through the winding n. The locking spring l acts both on the iron core of the coil n and on a pivoted lever k connected to the relay h. If the lever a is moved into braking position, the circuit of the relay h is closed and the switch i closes the circuit of the warning signal d' on the tram or other vehicle and also any trailer signals d<2> arranged in parallel therewith. If the lever a is pushed back into central position,the signals remain switched in since, the spring l presses the lever k against the core of the relay h. On the lever being moved to driving position, the circuit of the winding n is closed and the pull on its core releases the lever k against the influence of the spring and switches out the signals. When braking purely by hand a moving contact n, operated by a handle z co-operates with a contact v to work the signals.
