Title: Circuit for sampling high speed data
Inventor: WATSON GEORGE ARTHUR
IPC: G01S1/24
Filed: 1970-06-02
Abstract: 1285485 Radio navigation NORTH AMERICAN ROCKWELL CORP 2 June 1970 [25 Sept 1969] 26639/70 Heading H4D The invention relates to a circuit for dividing "Loran C" pulses into slower data samples, and utilizes a multi-stage pulse divider for dividing down a high-speed clock pulse signal having a frequency higher than the Loran radio frequency to slower-speed clock pulses for controlling the processing of data samples taken from two phase-related (e.g. master and slave) Loran signals; a multi-stage register holds a number indicating the precise instant in relation to a reference instant established by the slowerspeed clock pulses at which each sample is to be taken, a plurality of chains of sample storage devices transfer samples from the Loran signals to outputs whereat the data samples appear and gating logic controls the gating of samples from storage device to storage device in each chain, the gating logic being controlled by the number in the register in such a manner that the delay experienced by each sample appearing at one of the aforesaid outputs in traversing the corresponding storage device chain is that delay which corresponds to taking the sample at the corresponding one of the instants determined by the number in the register. Means responsive to the data samples changes the number in the register to such a magnitude that the data samples taken from the next Loran cycle tend toward a predetermined relationship between the samples corresponding to coincidence of one of the samples with a predetermined point in one R.F. cycle of one of the Loran signals. As described the pulse divider and the register are binary devices and each sample storage device is a bi-stable for holding a one-bit sample.

Abstract: 807,718. Stuffing-box substitutes. CRANE PACKING CO. Sept. 20,1955 [Sept. 20, 1954], No. 26909/55. Class 122 (5). A seal for a rotary shaft, such as a pump shaft 16, comprises a sealing washer 22 having a radial sealing face 26, and urged outwardly from a supporting retainer 30 by a spring 80, and a sleeve 50 of elastic material having a cylindrical portion 52 at one end surrounding and clamped to the washer, a deformable intermediate portion 62 and, at the other end, an inturned radial flange 66 abutting the end wall 36 of the retainer and clamped to the retainer by a metal confining ring 74. The cup-shaped retainer 30 is pressed into a counterbore in the pump housing 10 and has ribs 38 engaging longitudinal grooves 40 in the inner periphery of the washer. The end 52 of the rubber sleeve 50 is clamped to the washer by a metal ferrule 54 and the radial flange 66 has a thickened re-entrant portion 68 compressed against the retainer inner wall 34 by the ring 74. The washer 22 is urged into contact with a radial sealing face 28 on the pump impeller 18 by the spring 80. The seal is hydraulically balanced by shaping the sleeve to provide clearance 90 between part of the flange 66 and the end wall 36. In modifications, the confining ring has an axial portion that surrounds the spring adjacent the intermediate portion of the sleeve to prevent inward deformation of the latter. In the arrangement shown in Fig. 3, the radial flange 166 is compressed against the end wall 136 by the confining-ring 174 which is restrained from axial outward movement by a sharp edge 175 on its inner periphery that bites into the material of the retainer inner wall 134. The ring 174 is pressed into position during manufacture of the seal by pressing the washer inwardly until its rear face 179 contacts the edge 181 of the ring and then further pressing to force the ring into position, the axial flange 172 being longer than the fully compressed length of the spring 180. Specification 671,887 is referred to.

Abstract: 407,980. Alternating-current motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Morrill, W. J. ; 2317, South Wayne Avenue, and Pringle, W. A. ; 1022, Delaware Avenue, both in Fort Wayne, Indiana, U.S.A.) Sept. 28, 1932, No. 26965. Convention date, Sept. 29, 1931. [Class 35.] Cores.-In a synchronous induction motor of the type having no continuouscurrent exciting winding, the secondary member or rotor 11 which is excited by the primary flux comprises a core formed with salient poles the tips of which are rounded off, in the form of curves 17 intersecting at the deepest points of the intersalients. In addition to the slots 12 for the squirrel-cage bars a slot 18 may be formed at the centre of each salient of a depth sufficient to cause saturation of that portion of the core lying below it. A non-magnetic bushing 16 is interposed between the core and the shaft 15. Any tendency for the rotor to lock, or to crawl at some sub-synchronous speed may be overcome by designing the distributed stator winding so as to avoid the production of undesirable harmonic fluxes. The number of slots need not be an exact multiple of the number of poles and the deep slots 18 are not necessarily 180 electrical degrees apart.

Title: Improvements in or relating to screening can arrangements for thermionic valves
Inventor: HAMPSON JOHN ALBERT
IPC: H01J19/66
Filed: 1954-09-20
Abstract: 784,327. Discharge apparatus. MARCONI INSTRUMENTS, Ltd. June 16,1955 [Sept. 20, 1964], No. 27122/54. Class 39(1). A screening can 4 for a thermionic valve 1 has a spring 11 which encircles the valve, and is substantially wider than the space between valve and can, so that when the valve is inserted, the spring is substantially distorted and makes good thermal contact with both valve and can. A shoulder 12 prevents axial movement of the spring. The can is attached to a threaded member 6 which may be directly secured to the chassis 3, so that good heat conduction is promoted from the valve to the chassis. If it is desired to keep the chassis cool, the member 6 may be secured instead to a flange 15, which is separated from the chassis by a heat-insulating ring 17, the screening being completed by a metal foil sleeve 16 of poor conductivity. The can itself may have further cooling flanges, Fig. 7 (not shown). The spring 11 may be formed as a helical spring bent round in a circle, and then fitted into the can. Alternatively, the spring may be formed from a crimped metal sheet, as in Fig. 10, or a number of L-shaped pieces welded together. In this type of construction, the vanes 19 may be slotted, as at 20, for increased flexibility.

Abstract: 1,026,110. Blasting. PARIGBORN CORPORATION. July 2, 1964 [July 10, 1963], No. 27320/64. Heading B3D. An abrasive particle throwing wheel comprises: (i) a rotatable head, radially extending throwing vane channels extending into one face of the head, the width of the channels increasing as they extend into the head face; (ii) throwing vanes mounted in the channels to extend perpendicular from the head face, the vanes having an elongated cutout in the inner portion of the base of the vane; (iii) a compression spring resting on the floor of the channel and extending into the cut-out to urge the vane upwardly against the channel walls; (iv) a locking pin seat in the floor of the channel near the head periphery, a locking join in the seat which join extends upwardly into the channel, a second cutout in the inner portion of the vane base for accommodating that portion of the locking pin which extends into the channel; and (v) means at the head centre for urging the vane outwardly against the locking pin to form a tight fit. A runner head 1 mounted on a rotatable shaft 3 has in one face radial channels 11 having tapered side walls 29. A double-face vane 5 is introduced at the head periphery into a channel 11 and moved therealong until the innermost end abuts the centre stud 15 of the head. A locking pin 17 is inserted in a hole 19 in the head and the vane moved radially outward so that a tapered surface 21<SP>1</SP> on a cut-out 23 in the vane rides on a tapered surface 21 on the pin. A leaf spring 25 located in a cut-out 27 in the vane forces the vane upwardly in the channel. When all the vanes are in position, a locking ring 9 secured in an annular channel 13 around the centre stud 15, forcing the vanes against the locking pins. Single face vanes 7 are similarly secured, the locking pins 33, Fig. 9, being of simpler shape. The outer ends of the vanes are flush with the periphery of the head. In a modification, Fig. 16, the locking pin 42 for single face vane 40 has a groove or indent 44 facing the periphery of the head; to remove the pin, a screw driver or other blade is inserted in the indent and the vane wedged upward to remove the pin 42 from its hole 46. The cut-out 52 in the vane has a curved wall 34, the lower end of which abuts against the pin. The channels are shaped as shown in Fig. 17. A double face vane 60, Figs. 23 and 24, has the faces tapering inwardly at the inner end of the vane to eliminate bunching of the abrasive. The recess 64 in the head 1 for the locking pin 62 extends outwardly at an angle, e.g. 45 degrees, to the vertical.

Title: Improvements in or relating to means for controlling heating apparatus
IPC: F24C3/12
Filed: 1924-11-15
Abstract: 246,605. Lambert, F. T. Nov. 15, 1924. Portable heaters,-The container 14 for liquid has a heating means controlled by the movement of an actuating member 15 or 50 moved directly by the heated liquid or the vapour therefrom. and so shaped as to have between it and the bot. tom of the container a free space for the move. ment of the liquid or vapour. The connecting element. shown as the lever 30, 31, of the con. trol mechanism tends to move under gravity from a first position (for example an " on " position) to a second position (for example " off "), and is supported upon the actuating member so as to be tripped thereby and fall into the second position. In the example shown, the control mecha nism comprises a vertical tube 21 mounted or the body of a gas-cock and having an extension 22. A rod 23 sliding in the tube has a trans verse hole at its lower end through which gas passes when the hole registers with the gas-tube A pin 25 on the rod slides in a slot 26 in the tube to limit the motion, the gas being shut of when the rod is down. If it is desired that the boiling of the water in the container should shut off the gas, the rod 23 is raised until the pin 25 is supported by the detent 27, the gas then being on. On boiling, the rocking of the lid 15, oi other actuating member, causes the arm 30 to fall off the support 16 or 52 and moves the detent 27 from the pin 25, allowing the rod 23 to fall in the tube. By the use of stops 35, the rod may be allowed to fall only enough to reduce the flame. For starting the heating at a predetermined. time, an alarm clock 46 has a tie 47 connected to the hammer. On movement of the latter, a lever 40. 41 will be rocked and the end 43 will release a fork 44 which up to this time has held the rod 23 in a raised " off " position above the " on " position. The rod then falls till the pin 25 engages the detent 27 and the heating of the kettle proceeds as before. The handle 49<a> of the clock may be used to withdraw the pin 35 if such has been used. The actuating member may be a lid, baffle or float. A spring-loaded rotary plug gas cock or electric switch mav be released by the lever 30, 31 in place of the device described.
