Abstract: 1496159 Rolling apparatus; burnishing H G OLRIK 17 Dec 1974 [17 Dec 1973 25 Feb 1974 16 Sept 1974] 54542/74 Headings B3M and B3X [Also in Division F2] A method of straightening, burnishing or "calibrating" a cylindrical shaft, by means of a device otherwise used for converting rotary into linear motion. In this device, Figs. 1, 2, a friction drive unit 9 employs rolling bearings 47, 49 and 63, 65, as friction members, the inner diameter of each inner race 55, 57, 71, 73 being larger than the surface diameter of a shaft 17, against which they are eccentrically held under mutually balancing radial forces, and the rolling axis of each bearing being tilted relatively to the axis of the shaft 17, such that, under conditions of relative rotation between the rolling assembly and the shaft, each inner race rolls upon a helical path around the shaft, thereby imparting a relative linear motion, and the rolling bearings, supported in separate groups within a common cage member 23, are also provided with clamping means arranged in such a manner that the radial forces exerted on the shaft become increased in response to an increase in the axial load on the shaft. The pairs of rolling bearings may be secured within recesses in jaw members 37, 39, which are keyed by bolts 25, 29, to the rotatable cage 23, and the jaws 37, 39 are urged inwardly by a clamping means consisting of a winding of piano wire 81. When a load is applied to the shaft 17 in the axial direction marked K, one jaw member 37 abuts an end stop 83, while the other jaw member 39, frictionally drawn into a relative axial displacement, is arrested only by tensional forces in the clamping wire 81, causing the radial forces exerted on the jaw members 37, 39 to become increased. In other embodiments, the clamping means may consist of a cam or lever construction, with the effect of providing increased radial forces in response to an axial shaft load. The embodiment of Fig. 1 comprises an assembly of a friction unit 9 with a motor having a stator 3, a rotor 5, and a hollow motor shaft 7. Each inner race 55, &c. may be formed with an inwardly convex cross-section, adapted to contact the shaft along a line for the entire width of the race, thereby minimizing local stresses in the shaft surface. Alternatively, the race may have ridges projecting inwardly, to increase the shaft surface stresses. The device may thus be adapted for straightening shafts without surface changes, or for "calibrating" shafts by producing controlled surface deformation. In further embodiments, one or more of the bearing races may be inclined at a helix angle which differs from that of the remaining bearing races, thereby producing a burnishing action upon the shaft surface during relative rotation.

Abstract: 1,241,477. Pipe couplings. AEROQUIP A.G. 6 Nov., 1969 [29 Nov., 1968], No. 54547/69. Heading F2G. When male and female components 12, 13 of a high pressure disconnectable pipe coupling, are coupled, a stem valve 56, slidable within a fluid retaining valve 44 in the female component, opens against a spring 59, and allows fluid to flow at a controlled rate to a chamber 42, formed by the coupling of the components, increasing fluid pressure in the chamber and ultimately opening the fluid retaining valve 44, and a retaining valve 21, in the male component, against their associated springs 25, 52. The male and female components 12, 13 are coupled by radially movable balls 27 controlled by an external sleeve 28 slidable on the female component and the stem valve 56 contacts the male element retaining valve 21 to open the former. The stem valve 56 carries a pin 63 with a reduced portion 67, which, when the stem valve is opened, as shown in Fig. 2, is aligned with a seal 65, allowing fluid to flow at a controlled rate through the seal and an orifice 68, between the pin and the valve bore 64, to the chamber 42. Alternatively, the orifice 68 is replaced by a pressure relief valve which prevents flow to the chamber 42 until a predetermined pressure is attained in the female component. The fluid retaining valve in the male component may contain a stem valve, Fig. 7 (not shown), similar to that in the female component, which contacts the female component stem valve upon coupling, opening both stem valves and allowing fluid to flow at a controlled rate through orifices to the chamber from both sides of the coupling. The male and female components 12, 13 may be uncoupled by a direct pull on the male component, whereby the male component is released by the balls 27 and the stem and fluid retaining valves are closed. The female component may be located on a tractor and be connected to a fluid pump and a control valve, and the male component may be located on a trailer.

[Also in Division H3] A semi-conductor device comprises a transistor having a lead-in conductor extending over an insulating layer on the semi-conductor body and passing over an additional zone of opposite conductivity type to the surrounding body and having provision for applying an external D.C. and/or A.C. voltage to the zone. In an embodiment, the lead-in conductor is connected to the base of the transistor so that the capacitance between the base lead and the additional zone is in series with the capacitance of the PN junction between the zone and the collector of the transistor, thus reducing the base-collector capacitance of the device. The capacitance of the PN junction between the zone and the collector can be varied by the bias voltage applied to the zone. This capacitance is connected in parallel with the tuned circuit of an oscillator incorporating the transistor so that variation of the bias voltage alters the frequency of oscillation. The circuit may be utilized to provide A.F.C. in an F.M. receiver. Alternatively an A.C. signal can be superimposed on the D.C. bias to provide a frequencymodulated oscillator. The transistor can also be used in a tuned amplifier, the voltage-variable capacitance between the zone and the collector being included in the tuned circuit so that the centre frequency can be varied by means of the D.C. bias applied to the zone.
