Abstract: 1,131,601. Laminated fibrous mats. SIEMENS-SCHUCKERTWERKE A.G. 27 Jan., 1966 [28 Jan., 1965], No. 3822/66. Heading B5N. A fibrous support material lying on a further support is impregnated with an oxygen-containing mixture comprising also a polymer or copolymer of a conjugated diene and, as a crosslinking agent, an ethylenically unsaturated monomer, a hardener capable of effecting the cross-linking, and a powdered filler. The product can be hardened under heat and pressure, but is preferably covered by a further support and rolled up and stored until ready for use. In examples silanized glass fibre mats lying on polyethylene foil supports are coated with an oxygen-saturated resin mixture of butadienestyrene, divinyl benzene (one example includes also styrene), 2,5 - dimethyl - 2,5 - di - (tbutylperoxy)-hexane, calcium stearate (lubricant), a silicone finish, an antioxidant (one example includes also a U.V. stabilizer) and powdered calcium carbonate and, after, in one case covering with polyethylene foil, are rolled up until ready for use.

Title: Feed control device for agricultural harvesting machines, for example, grain harvesters

IPC: H02P29/00
Filed: 1966-02-01
Abstract: 1,141,961. Combine harvesters. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY I N S T I T U T SELSKOKHOZYAISTVENNOGO MASHINOSTROENIA. 1 Feb., 1966, No. 4367/66. Heading A1F. [Also in Division G3] A control device, for automatically adjusting the ground speed of a harvesting machine, e.g. a combine, in dependence on the volume of material fed into the machine and the rate-of handling of the material in the machine, e.g. by a threshing mechanism, comprises a unit for sensing the volume of material gathered, a rate-of-treatment control unit, and a slide valve controlled by the volume sensing unit, which valve controls the operation of an hydraulic cylinder connected to a variable speed gear through which motion is adapted to be imparted to the driving wheels of the machine. The device further includes an automatic adjustment means comprising an actuating mechanism controlled by the rate-of-treatment control unit and operatively connected to the slide valve or the volume sensing unit, and a timing device ensuring the required duration of operation of the actuating mechanism. As illustrated the volume sensing unit is an arm 17 positioned e.g. in the crop elevator and connected to the piston 12 of the slide valve, which controls via hydraulic cylinder 6 the variable speed gear 7. When the volume of material being threshed rises above or falls below a predetermined value a governor 2 which comprises the rate-oftreatment control unit causes one of the contacts 18, 19 to close and actuate a reversible electric motor 8 in one sense or the other. The motor is connected by reduction gearing 14 and a shaft 15 having a screw thread which engages a screw thread in a housing to a sleeve 16 on the slide valve. Operation of the motor effects displacement of the sleeve and consequently causes the setting of the arm 17 to be varied. Each operation of the motor is limited by a timing device 9. In an alternative embodiment (Fig. 2, not shown) the sensing arm causes actuation of the piston of a slide valve by electro-magnetic means. The motor is replaced by a step-by-step selector and the timing device is constituted by an arrangement of relays and capacitors.

Title: Improved skip bucket

Abstract: 718,411. Pneumatic single-stroke apparatus; pipe joints. JOHNSON CO., C. S. Feb. 21, 1950 [Feb. 26, 1949], No. 4469/50. Classes 8 (2) and 99 (1). [Also in Group XXX] In a concrete bucket of the bottom dumping type (see Group XXX) at least one discharge gate is opened by movement of a piston and cylinder actuator operated by a source of compressed air, and control means for the actuator includes a reservoir of compressed air selfcontained within the bucket structure, and means operated as an incident to decrease in pressure either at said source or at a detachable connection to said source, for supplying air from the reservoir to said actuator to reverse its former movement and thereby close the gate. Air from a supply pipe 151 is fed to the front or rear of a pair of such actuators 50, 50a according to the position of a valve 150. Valve 150 is operated against the pressure of a spring 153 normally holding it in lowered position by means of a piston 152 operating in a small cylinder supplied by a pipe 154. When an air lance 140 is inserted in either of two sockets 135, 136, air passes to a control device 160, Fig. 7. A ball 170 is caused by the inlet of air to close the pipe leading to the socket not in use. Air is then simultaneously supplied to the pipe 154 and via a spring-loaded ball 175 to a reservoir 161 and to the pipe 151. Valve 150 is thus moved into its upper position and as reservoir 161 is charged, air from pipe 151 enters the front ends of the actuator 50, 50a, to open the gates of the concrete bucket. Upon removing the air lance 140, valve 150 drops to the lower position while air is still supplied through pipe 151 by the reservoir 161. This air passes to the rear of the actuators 50, 50a thus closing the bucket gates. Pipe joints.-Each of the sockets 135, 136 consists of a conical aperture 184 and a flexible lip 182 arranged to give self-sealing of the lance 140 which can be inserted at any angle within the conical aperture.

[Class 46] [Also in Groups VIII and XXXVII] The speed of squeeze rollers 7, Fig. 1, for separating liquid from material such as cellulose acetate, paper pulp or bagasse, is controlled by a feeler 11 which contacts with the surface M-of the material as it is fed as a layer to the rollers. The feeler 11 is carried by triangular web arms 13, fixed to short pivot shafts 14, 18 mounted in the walls of the chute down which the material passes. The shaft 18 has a counterweighted arm 19 and the shaft 14, Fig. 2, is provided, outside the chute wall, with cams 23, 24, 25, engaged respectively by pivoted levers 29, 36, 38, which operate electric switches, 33, 37<SP>1</SP>, 40, Fig. 6. When the surface M of the layer rises beyond a limiting portion C the lever 29 closes the switch 33 of a pilot motor 34, which controls a rheostat 34<SP>1</SP> in the circuit of the motor 35 driving the rollers 7 and increases the speed of the rollers. Similarly when the surface M falls below the position B, the lever 36 moves to decrease the speed of the rollers.
