Title: Improvements in or relating to ball and roller bearings, particularly those for rectilinear motion
IPC: F16C29/04
Filed: 1942-12-02
Abstract: 559,326. Shock-absorbers. RIBBESFORD CO., Ltd., THORNHILL, P. W., and ONIONS, J. H. Dec. 2, 1942, No. 17164. [Class 108 (iii)] [Also in Group XXXIV] Rectilinear bearings, comprising balls or rollers between an inner member 13 and an outer tubular member as used in shock absorbers or aircraft telescopic struts, have an auxiliary race 25 which is resiliently mounted to permit canting between the members. The inner member 13 terminates in a piston within a cylinder 10 which is provided with an end casing 17, Fig. 3, threaded into the cylinder 10 or secured thereto by threaded sleeve. The sleeve 25 forms a race for the balls or rollers 27 which are contained in a cage 28, and is spaced from the casing 17 by rubber rings 48 which may be wide and spaced or narrow and contiguous. A packing of laminated canvas 45 and rubber 46 seals the cylinder 10. The rollers may be barrel shaped with scalloped races or they may be of the flexible spring variety consisting of helices of steel wire ground smooth upon their external surface. In a modification, Fig. 4, the race 25 has conical parts 54, 55 engaging conical rubber sleeves 29, 31 and a central convex part 51 engaging the casing 17 to provide a rolling contact. In a further modification, Fig. 5, the race 27 is mounted on flexible spring rollers 64, 65 carried by cages 66 and directly engaging the cylinder 10 which has a reinforcing cap 56 with end flange 57 and packing 58, a stop ring 59 being provided. The balls or rollers may engage the outer member whilst the resilient mounting engages the inner member 13. The Provisional Specification refers to Specifications 479,533, [Group XXXIV], and 502,705.

Abstract: 648,311. Centrifuges. SOC. ALFALAVAL., and SOC. BELGE ALFA-LAVAL. June 30, 1947, No. 17208. Convention date, July 4, 1946. [Class 23] [Also in Group VI] The Specification as open to inspection under Sect. 91 describes a centrifuge used for clarifying beer in which the bowl 51 rotated by shaft 52 has a cover 53 formed with a central hole 54 through which projects a raw beer inlet 55 and a pipe 56 for the outlet of degassed beer. As the beer falls into the bowl 51 the CO 2  is released and is preferably driven off through 54 by air flow caused by a centripetal pump 58 at the bottom and a centrifugal pump 59 at the top of the bowl. The stripped beer flows below the lower edge of the bellshape member 60 through ducts 62 to the orifice 63 of a centripetal pump through the channel 64 and out of delivery pipe 56. An air-oxygen mixture is introduced into the clarified beer as it enters the orifice 63. This subject-matter does not appear in the Specification as accepted.

[Class 141] [See also Group IX] Apparatus for crimping textile fibres in the form of a continuous sheet or sliver, in the sense of imparting a notched, crenated or serrated form in contrast to undulated or corrugated, comprises a blade B, Fig. 1, B<1>, Fig. 2, of hardened steel or other material shaped like a chisel and resiliently pressed into the nip of two rollers A, A<1> between which the material is passed so that the edge is against the roller A and the bevelled face against the roller A<1>. The material as it is delivered by the rollers is compressed against the blade and issues between the roller and the bevelled face as it forces the blade against the action of a spring C, In Fig. 3, a machine is shown for material in the form of stricks or bunches of fibre or heavy slivers which require a number of operations to effect the crimping. The material passes from a conveyer G to plain or fluted rollers, or plain rollers provided with a blade under slight spring pressure so that the material is flattened but not crimped, and then to a number of pairs of rollers with crimping blades, each succeeding pair of rollers being driven faster than the previous so that the material is straightened before each crimping, the last pair of rollers being plain without blades. Pieces of material fed to the machine may overlap on the conveyer so that a continuous ribbon is treated which may be separated into the original components by suitably adjusting the speed of the last pairs of rollers.

Title: Device for measuring a time interval

Abstract: 1384585 Measuring short time intervals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 April 1972 [20 April 1971] 17597/72 Heading G1U [Also in Division H3] A short unknown time t 1 , which is difficult to measure, is effectively magnified (by a factor of the order of 1000) to give a time t2 which is more easily measured. As described, the unknown time t 1  is manifested by closure of a switch Si, Fig.1, thereby allowing a capacitor 14 to charge, Fig.3, and the magnified time t2 is the time taken for the capacitor to discharge, which can be measured 21 in any conventional manner. The circuits described also have the property that the discharge potential 28, Fig.3, strikes the zero level with a definite non-zero slope α, rather than being asymptotic thereto. The specification shows that if R 1  2  = R 19 , and if current through resistor 12 is assumed to flow entirely to the capacitor 14 when switch S 1  is closed, then t 2  = t 1  R 17 /R 22 . In a modification Fig.4 (not shown) by means of a gating circuit (24) and two monostables (3), (4), the capacitor is allowed to charge for a period tref - t', where t ref  is the 'on' time of the monostable and t' the time between the leading edges of two pulses (1), (2), and in a second modification Fig.5 (not shown) the capacitor is charged by an input pulse (29) of unknown duration and the pulse is also stored (30) to provide a source of voltage for the circuit during the discharge phase.
