Title: Process for the production of slabs and shaped parts from fibre-reinforced binders with reduced setting times
Inventor: KARGER WALTER
IPC: C04B28/14
Filed: 1961-09-29
Abstract: 959,110. Drying moulded fibre reinforced plaster. DEUTSCHE BANAKADEMIE. Sept. 29, 1961, No. 35153/61. Heading B5A. [Also in Division E1] The setting or drying time of multi-layer pressed or unpressed fibre reinforced plaster slabs is decreased by the application of dry pulverous plaster between wet layers of fibre reinforced paste. A paste of modelling plaster and glass fibre, and containing keratin waste products, alum, or synthetic resins for regulating the setting or hardening characteristics, is spread evenly on a shaping surface; and drymodelling plaster containing dihydrate is applied thereto prior to pressing at 5 kgm./sq. cm. Alternatively, plaster paste from two or more vessels is successively applied to a shaping surface with a fibre mat introduced into each layer, followed by a spreading of dry plaster. Cold-hardening synthetic resin with or without the addition of soluble or insoluble binding agents or other hydrophobic additives may be applied to protect the finished slab from moisture. Even setting of a multi-layer slab is ensured by variation of the proportion of water or by using additives which regulate the setting speed in successively applied layers.

Title: Improvements in or relating to agricultural baling machines
IPC: A01D85/00
Filed: 1956-11-22
Abstract: 819,287. Baling-machines. LUNNON, J. F. Nov. 21, 1957 [Nov. 22, 1956], No. 35728/56. Class 94(1). A machine of the travelling " pick-up " type incorporates a feeler which detects the presence of a bale already deposited on the ground and operates mechanism for releasing at least one further bale and depositing it on the ground in close proximity to the detected bale. The mechanism may be incorporated in a trailer which is towed behind the machine and receives completed bales from the baling chamber. In the machine shown, the floor of the baling chamber is extended by a fixed platform 14 to which is pivoted at 15 a bale-delivery platform 16. The latter is normally maintained in a horizontal position in which it forms a continuation of the platform 14, by pivoted catches 28 engaging over a bar 27. A transverse rod 23 is rotatable in a framework secured to the platform 16 and carries feelers 24 arranged to engage a bale such as 25 which has already been deposited on the ground. When the feelers encounter the deposited bale, the rod 23 is rotated and abutments thereon disengage the catches 28 so that the platform 16 swings downwardly against the action of springs 31 to deposit a further bale adjacent the detected bale. The springs 31 then return the platform to its initial position and the catches reengage automatically. The platform 16 may be fitted with a pivoted stop 32 which prevents undesirable release of bales, e.g. when the machine is travelling up-hill, the stop being swung to an inoperative position by engagement with the ground when the platform swings downwardly. The rod 23 may be rotated manually by control mechanism 33 to deposit bales at any desired spacing during the first circuit of the machine around the perimeter of a field.

Abstract: 345,322. Friction clutches ; slipping couplings. BETHLEHEM STEEL CO., Bethlehem, Pennsylvania, U.S.A.-(Assignees of Nieman, H. W.; 115, East Market Street, Bethlehem, Pennsylvania, U.S.A.) Nov. 22, 1929, No. 35827. Convention date, Dec. 27, 1928. [Class 80 (ii).] A friction clutch, particularly applicable for the unloaded starting of motors, comprises a weighted flexible band under tension, the torque transmissible being increased with the speed of the driving-member due to centrifugal action on the band, which has an angle of wrap of not less than 180‹, so that the transmissible torque shall be substantially unaffected by variations in the co-efficient of friction. An arm 16, Fig. 2, on the driving-shaft 14 engages one end of the clutch band 19, which is provided externally with a facing 20 having a high minimum co-efficient of friction (say, 0-35), and internally with brass &c. weights 21, preferably uniformly-distributed. Above a certain minimum speed, the band engages centrifugally a drum 11 on the driven shaft (not shown), in which the shaft 14 is spigoted. The direction of rotation, shown by the arrow a, is such that the band is in tension. The e band may be replaced by a helix. Figs. 4 and 5 show a form suitable for bi - directional rotation, two driving-pins 31, 32 engaging respectively slots 38, 39 in the weighted band 33, so that one or other pin engages the end of its slot, according to the direction of rotation, and drives the band always in tension. A second band 34, with diametricallyopposed driving-pins 31<1>, 32<1>, is provided to improve the balance. In this form, the shafts 13, 14 are not spigoted together, the clearances allowing angular and lateral displacements thereof. The centrifugal weights may be of non- uniform mass ordistribution, and the friction facing may be thicker at the ends, particularly the free end. The Specification as open to inspection under Sect. 91 (3) (a), comprises also the following subject-matter: Fig. 6 (Cancelled) shows a slipping coupling, in which the weights are replaced by radiallyacting springs 53. The band may act externally on the drum and either member may drive, provided that an expanding-type band is subjected to tension and a contracting-type band to compression under drive. This subject-matter does not appear in the Specification as accepted.

Heading F2F. In a brake valve for power-assisted hydraulic brakes for motor vehicles in which a valve member 30 can be shifted manually by way of force-transmitting means, against the force of a valve spring 39, to allow pressure medium to flow from a reservoir via port 6 to wheel brake cylinders connected to the aperture 41, the force-transmitting means, which comprise a piston-rod 10 associated with a master cylinder 8, a piston 9 thereof, and the pressure medium column produced therein, such means operating the brake valve control piston 36, also comprise an actuating element 29 having spring- loaded means 46 whose force corresponds to the force of the valve spring 39 and which bear against the brake valve casing and, at the end of the actuating movement of the actuating device, act upon the brake valve-control piston. A part of valve passages 2 and the master cylinder bore 3 are interconnected by an annular passage 4. On operation of the pedalactuated rod 10 pressure medium is displaced from the master cylinder 8 and passes through the annular chamber 4, a chamber 38, and ducts 27 into the working chamber 37 of the control piston 36. Simultaneously, a lever 49 is moved to the left by sleeve 12 and spring 13 acting thereon to cause the actuating device 29 to pivot around the apex of its knife edge 53 so that a ball 48 rolls in socket 47 and on a track 50 until it engages a push-rod 51. In this position the force of the valve spring 39 is compensated for by the force of a spring 45 after the piston 36 has moved to close the gap 55 and cut off communication of the brake cylinders with port 7 connected to a return reservoir. Further movement of the piston-rod 10 causes the control pressure in the chamber 37 to increase and thus move the valve member 30 to connect the brake cylinder to the pressure source 6.
