Title: Improvements in bale handling machines
Inventor: WEHDE JAMES FRED
IPC: A01D85/00
Filed: 1967-08-15
Abstract: 1,202,373. Bale carriers. J. F. WEHDE. 15 Aug., 1967 [15 Aug., 1966], No. 37349/67. Heading B5F. [Also in Division B8] Bale handling apparatus comprises means for delivering bales on to a bed 17 at a height at least equal to the height of a bale, means for automatically displacing a pile of bales laterally on the bed 17 through at least one bale width and means for automatically discharging a load of accumulated bales. The bales are delivered from an opening 15 of a baling machine, the first bale dropping on to the bed 17. The second bale slides over the first and engages a trip lever 33 operatively connected to an hydraulic ram 37. The ram 37 is connected to a plate 46 for pushing the two bales sideways on the bed 17. When these bales are pushed by subsequent bales to the extreme right of the bed 17 they engage a detector lever 51 which, through linkage 52, 54-56, rotates a shaft 34 through 90 degrees thereby replacing the first trip lever 33 by a second lever 57. When the final bale engages trip lever 57 a toggle 61, 61a (Fig. 5) is operated and the bed 17 is tilted to discharge the complete stack of bales on to the ground. The pivot 64 of the bed 17 is so placed that when the bed is not loaded it is heavier at the front and therefore rests in the horizontal position, in which it is locked by the toggle 61, 61a until a cable 60 is tensioned. When loaded, the bed is heavier at the back.

Title: Improvements in or relating to a method of making polymer films
IPC: B29C41/24
Filed: 1957-12-02
Abstract: Polymer films are made by forming a film of a castable polymer upon a silicone-coated ceramic or metal plane casting surface and then removing the film therefrom.  The casting surface may be a metal or alloy foil, e.g. an aluminium foil, coated with a silicone varnish, resin or rubber, e.g. a dimethyl siloxane resin or phenyl methyl siloxane resin, which is preferably cured before the polymer film is formed thereon.  The polymeric film-forming material may be applied as a melt or cast from an aqueous dispersion, optionally containing a wetting agent of the alkyl aryl alcohol type, and sintered into a film on the coated surface. Specified polymeric film-forming materials are polyhaloethylenes, e.g. polytetrafluoroethylene, polytrifluorochloroethylene and polytetrachloroethylene.

[Also in Group XL (c)] A device for deriving digitized binary signals representing the sine or cosine of an angle comprises a digit disc 40 and a second disc 65 which is angularly displaced relative to the disc 40 by half a sector, the sectors being indicated by the full radial lines, Fig. 2. The markings on the digit discs are sensed by brushes, or by photo-cells, Fig. 3. Peripheral markings 55, 56, 57 are sensed by cell 60 in the latter case, and the cell output passes to a switch control 61 which feeds a switching circuit 62 so that the sensing system reads only from the disc whose centre of a sector is near the photo-cells. Difficulty which might occur in sensing at a sector boundary is thereby avoided. The Provisional Specification states that the Gray code may be used on the digit discs.

Title: Lubricating oil additives
Inventor: SPIERS JAMES ALEXANDER LYON
IPC: C10M135/04
Filed: 1954-12-31
Abstract: An oil solution of a sulphurized terpene, useful for addition as an anti-oxidant to mineral lubricating oils, is prepared by reacting a monoor di-cyclic terpene with sulphur in the absence of lubricating oil, steam-distilling the reaction mixture, initially in the absence of lubricating oil, at a temperature below the decomposition temperature of the sulphurizd terpene to remove the lower-boiling components of the reaction mixture, and adding mineral lubricating oil to the reaction mixture during the steam distillation.  The terpene may be dipentene, carene, alpha-pinene or camphene. Lubricating oil compositions, prepared by mixing the oil solution with further mineral lubricating oil, may also contain other additives such as detergents, anti-wear agents, rust and corrosion inhibitors and extreme pressure agents.

Abstract: 324,778. Kr³ger, W. Dec. 24, 1928. Variable-speed gearing.-A is arranged within the same casing as auxiliary gearing B provided to facilitate changing speed. The first shaft 25 of gearing B is connected by a chain &c. 34 to a friction clutch member 26 loose on driving- shaft 9 of main gearing. The second shaft 16 of gearing B is constantly connected by gear train 14 to the driven shaft 1 of main gearing. If, for example, it is proposed to enmesh the main gear pair 5, 2, the engine clutch 11 is disengaged by moving cone 10 to the right. This carries cone 27 into engagement with cone 26 so that shaft 25 of gear B is geared to the countershaft 7 of the main gearing. Clutch 31 is engaged. Gear pair 19, 23 corresponds to pair 5, 2 so that vehicle road wheels drive from shaft 1 through train 14, 16, 19, 23, 25, 34, 26, 8, 28.

To provide an input impedance that is the same whether the cross-point of a switching matrix is open or closed, the cross-point has a capacitor C1 which is connected to earth when the cross-point contacts are open but is disconnected when the contacts are closed and an equivalent leakage capacitance is seen from the input. An inductor L1 and resistors R1 and R2 are used to match the cross-point input impedance. To obtain a value for the capacitors C1, the stray capacitance C5 may be calculated or measured at points of the matrix to obtain an average value. Transmission time from any input to any output is the same. The crosspoints may be individual packages plugged into a chassis having coaxial cable co-ordinate wires.
