Title: Improved bolsters for spinning mules
Inventor: WALMSLEY JOHN
IPC: D01H3/00
Filed: 1949-08-25
Abstract: 673,763. Bearings. MORGAN CRUCIBLE CO., Ltd. Nov. 23, 1950 [Aug. 25, 1949], No. 22143/49. Addition to 610.967. Class 12 (i). In a modification of the mule spindle bearing according to the parent Specfication, each bush 8, Fig. 3. is mounted in a separate bushhousing member 6 which is detachably secured to a supporting frame 1 therefor. The frame 1 has a horizontal flange 3 in which circular holes 5 are drilled for receiving cup - like bushhousing members 6. The members 6 have squared rims 7 which bear against the frame 1 and upstanding portions 4 on the flange 3. A long coverplate 9 having countersunk holes 10 corresponding to the holes 5 is secured by screws to the flange 3. In another modification, a supporting frame 21, Fig. 5, has a horizontal flange 22 which acts as a cover-plate, and cup-shaped bush-housing members 24 are screwed to the underside of the flange 22. In a further modification, each bush housing is in two parts 33a., 33b, Fig. 7, which are screwed to a frame 31 by screws 34, and a locating flange 32 on the frame 31 engages a groove in the part 33a. In a final modification the bush-housing member is in two parts 43a, 43b, Figs. 10, 12, which are secured to the backing- plate by bolts 44 having dovetailed heads located in a longitudinal groove 42 in the member 41. A locating flange 45 is provided on the member 43a and engages the groove 42. The frame may be made of cast or sheet metal or moulded synthetic resin.

Abstract: 917,421. Engine construction; free piston gas generators. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE. June 29, 1959 [June 30, 1958], No. 22209/59.

Title: Improvements in and relating to methods and devices for producing electric oscillations
IPC: H01J25/12
Filed: 1959-06-29
Abstract: 924,865. Velocity-modulated tubes. EITELMcCULLOUGH Inc. June 29, 1959 [Aug. 29, 1958], No. 22224/59. Class 39 (1). A bunching process, described as " secondorder velocity modulation " consists in velocitymodulating a beam at one location and then applying at a suitably-spaced subsequent location a reversed velocity modulation such that previously accelerated electrons become retarded ones and vice versa; it is shown that this process tends to cause the electrons to congregate towards the points of zero field and if repeated a sufficient number of times gives a beam with two tight bunches per cycle. To secure correct initial phasing the velocitymodulating field at the first gap 41, Fig. 1, should have half the magnitude of the succeeding gaps 42, 43, 44 and this is also true of the final gap 45 before entry into the output gap 40 in the harmonic resonator 16; this is secured by a narrower spacing of gaps 41, 45 within the fundamental resonator 18. The drift tubes 21 . . . 24 screen the beam during one or an odd number of half-cycles of the fundamental frequency and are supported by spiders 30, or tapered struts, Fig. 3 (not shown), or by walls dividing the resonator into a number of cavities connected to oscillate in phase by loops; alternatively, in the latter form, the tubes could be a full cycle in length and the loops would then cause successive cavities to oscillate in opposition, Fig. 5 (not shown). Alternatively, there may be separate cavities independently excited in the appropriate phases. It is shown that the arrangement also produces stable radial focusing. To secure an output at the fundamental, the last drift tube 24<SP>1</SP>, Fig. 12, may be made of length equivalent to one or an odd number of quarter-cycles. Successive bunches are then accelerated and decelerated and tend to merge into a single bunch which excites fundamental output resonator 170. This " bunching of the bunches " may be carried out in a separate resonator intermediate 18 and 170, Fig. 13 (not shown). The modulated beam may alternatively be passed directly into a particle accelerator. In a modification, each " location " may be replaced by a group of locations all modulating the beam in the same phase. The cavities may be replaced by a helix with periodic variations in pitch or a number of spaced helix sections. Ion beams can be similarly modulated.

Abstract: 913,191. Endless conveyers. BROWN INDUSTRIES Ltd., DAVID. June 26, 1961 [June 25, 1960], No. 22316/60. Class 78 (1). [Also in Group XXII] In a machine-tool an automatic loading and unloading device comprises a transfer arm 10 pivotable about an axis parallel to a workpiece axis 9 and about its own longitudinal axis. In a gear-shaving or hobbing machine, the arm 10 is rotatable in bearings 13 in a housing 12 on a shaft 15 rotatable through 160 degrees in bearings in a housing 16 by an hydraulic motor 18. A work - engaging fork 21 is reciprocated on the arm 10 by a piston 24. When the shaft 15 is rotated, a cam 37 in the housing 16 moves a follower on a rack piston 34 to cause the arm 10 to rotate through 90 degrees. The housing 16 is reciprocated on bars 40 to pick up or deposit a gear from a conveyer 47 moved intermittently by hydraulic means. The machine loads a gear automatically between automatically-operated centres and returns the finished gear to the same position on the conveyer. In a modification, new workpieces are taken from one conveyer and finished workpieces are placed on another.

Abstract: 644,063. Thermal switches. GENERAL ELECTRIC CO., Ltd., HUMPHREY, R., and HUNT, M. H. Aug. 15, 1947, No. 22737. [Class 38(v)] [Also in Group XIII] Relates to a thermo stat comprising a temperature - respon sive capsule having a diaphragm 5 upon which bears an annular or interruptec annular flange 12, of a pressure member 9 which bears on the diaphragm, at a distance approximately midway between the centre and periphery thereof, with variable pressure to adjust the temperature at which the diaphragm snaps over its dead-centre position. According to the invention, in such a device e.g. for a refrigerator, a leaf spring 23 carrying a member 26 for bridging a pair. of switch contacts 21, and having a button 25, bears on the centre of the diaphragm with constant pressure. The leaf spring passes through slots, Fig. 3, in the flange 12 or, in a modification, through a hole in the cylindrical part 11 of the pressure member. Adjustment of the pressure of this member is by means of a compression spring 15 and a nut 18 movable on a threaded, rotatable spindle 14 but restrained from rotation by a lug 19 engaging a slot. A projection 28 from the cylinder 11 is provided which bears on the leaf spring 23 to ensure breaking of the contacts when the diaphragm snaps downwardly and when a cam 30. rotated by the spindle 14 depresses a pin 31 for a definite " off " position. The diaphragm 5 is of precipitation-hardened beryllium copper about 0.006 .inch thick and is actuated by the saturated vapour pressure of a liquid which fills the capsule and capillary pilot tube 7 at normal temperature.

Filed: 1953-08-25
Abstract: 729,882. Valve circuits; pulse code modulation. NATIONAL RESEARCH'DEVELOPMENT CORPORATION. Aug. 25, 1953, No. 23468/53. Classes 40 (5) and 40 (6). In a circuit for comparing a given voltage with a reference voltage in which the given voltage is applied to a trigger circuit to change it to its second stable state if the given voltage exceeds a predetermined value, the trigger circuit is returned to its first stable state immediately prior to the time when the comparison between the two voltages is made. The Figure shows a comparison circuit in which the given voltage is applied at t2 to the grid of valve V2 which is cross-coupled with valve V3. Negative-going short re-setting pulses of large amplitude compared with the given voltage are applied at t1 via valve V1 and transformer T to the grid of V2 so that valve V2 is normally cut-off and valve V3 conducting. The reference voltage, which is varied by the setting of potentiometer R2, is such that if at the termination of a negative pulse at t1 the given voltage applied at t2 exceeds the reference voltage, the circuit comprising valves V2, V3 is triggered to its second stable state to generate a positive output pulse at terminal t3, Fig. 2 (not shown), which persists until the circuit is reset to its first stable state by the next negative pulse applied at t1. The circuit may be used in a pulse code modulator when a " 1 " or " 0 " pulse is obtained at the output t3 in dependence upon the signal potential applied at t2 being greater than or less than a given potential at certain periodic sampling times. In a modification, a D.C. restorer diode D is connected in the grid circuit of valve V3, The pulse transformer T preferably produces some overshoot on the trailing edge. of each pulse, thus ensuring that the circuit is re-set to its first stable position .if it is not already in that state.
