Filed: 1943-09-16
Abstract: 574,846. Safety razors. AUERBACH, Z. Sept. 16, 1943, No. 15230. [Class 30] A safety razor head made from a single piece or two pieces of sheet material, comprises cap parts 75, Fig. 6, separated by a narrow longitudinal central slot, bent guards 76 and base portions 77 spaced from the cap parts to form a passage for endwise movement of the blade. In the one-piece form, Fig. 6, the parts 77 are integrally connected by a part cylindrical spring portion 78 to which the handle 81 is secured and which acts to press the opposite sides of the head towards each other so that abutments 79 secured to the guard parts 76 grip the opposite edges of the blade. In the two-piece form, Fig. 4, the base parts are separate and bent to form outwardly diverging tongues engaging a tubular spring 55 on the handle. In a further form, Fig. 10, the base is provided with a depressed part 91 to accommodate a blade flexing member 96 operated by a shaft 97 passing through the handle. A blade magazine for use with the razors shown in Figs. 4 and 6, comprises a box-like member in which a pile of blades is spring pressed upwardly to be fed one by one by a pusher 71, Fig. 2, carried by a slide 70, out through a slot 68 in the front of the box, the front having a tongue 67 which is adapted to engage the slot between the cap parts and spread them apart to allow of free passage of the blade between the abutments 79. The sides 63, top 66, front 65, tongue 67 and back of the box are made by bending a suitably shaped metal blank. Figs. 15, 16 and 17 show a magazine for use with the razor of Fig. 10. The sides 101 of the magazine have their upper edges bent over and downwardly at 102 to form channels 107 and then horizontally to form platforms 103 which are provided with upstanding ribs 104. The front portions of the inner walls of the parts 102 are bent inwardly at 105 and those of the platforms 103 upwardly at 106. The box has a fixed sloping back wall 108 and a front wall 109 pressed upwardly by a spring tongue 110, and formed with outwardly bent platforms 111 and an inwardly bent projection 112 lying over the upper blade of a pile pressed upwardly by a spring 113. To use the magazine, the razor is inverted and pressed downwardly on the platforms 111 at the same time being pushed into the magazine with the guard parts engaging the channels 107 and the depression 91 in the base lying between the ribs 104. The pressure on the platforms 111 depresses the wall 109 causing the projection 112 to escape from the top blade and engage the next lower blade. The channels 107 are further apart than the guards so as to spread the razor head to permit free entry of the blade which as it enters ejects the old blade. The blade magazines described form the subjectmatter of Specification 574,864.

Title: Improvements in and relating to Bronzing Apparatus.
Inventor: GILBERT FRED
IPC: B41G1/00
Filed: 1916-10-28
Abstract: 108,956. Gilbert, F. Oct. 28, 1916. Addition to 12097/12. Bronzing.-Instead of employing air pressure to assist the flow of bronze powder from the container to the sheet or the like to be bronzed, the bronzing-apparatus described in the parent Specification is provided with means for positively forcing the bronze out of the container. A slidable plate 2 is mounted in the bottom of the container 1 and is provided with holes 3, which may be moved into partial or complete register with holes 4 in the bottom of the container by means of a push-rod 5, but are normally held out of such register by a spring 9 on the push-rod 5. Plates or projections 10, provided with curved ends and preferably sloping forwards, are provided on the plate 2 adjacent to the holes 3, and when the pushrod 5 is pushed inwardly, the projections 10 act to scoop the bronze forward and force some of it through the holes 3, 4. The extent of the forward movement of the plate 2 is adjustable to regulate the feed, by means of an adjustable stopscrew 11 which may be provided with a lock-nut 13. The bronzing-device may be readily replaced by others, according to the class of work, by disconnecting the screw, bayonet-joint, or other suitable coupling 14, 15 connecting the device to the suction pipe 16.

Filed: 1925-06-13
Abstract: 235,594. Tavannes Watch Co. Soc. Anon. June 13, 1924, [Convention date]. Projectile fuzes. - Relates to clockwork fuzes wound up and set simultaneously by means of a key connected by a countershaft to the spindle of the power spring. According to the invention, the countershaft is made in two telescopic parts 5, 6, the outer part 6 carrying a pinion 9 in constant mesh with a pinion on the power spindle (not shown) and the inner part 5 slidably feathered into a pinion 8 in mesh with a pinion 7 on the aforesaid key (not shown). The part 5 is held in the extended position shown by a split spring ring 11, but sets back into the outer part 6 on discharge, thereby disconnecting the key from the clockwork mechanism, and leaving a clear space between the plates 2, 3 for the swing of the balance 1H. The set back of the part 5 also releases a centrifugal arm 14 provided with a finger 16, which, in the outward swing of the lever about its pivot 15, imparts an initial impulse to the balance 18. In a modification, the split spring ring 11 is situated above the pinion 8 and beneath a bridge secured to the plate 2: and the centrifugal arm 14 is omitted, the initial impetus being imparted to the balance 18 by a bevelled face of a notch in the part 5. Specification 219,941 is referred to.
Patent GB-662276-A (GB)
Title: Improvements in or relating to depth sounders
IPC: G01S15/10
Filed: 1949-06-09
Abstract: 662,276. Echo sounding and distance measuring apparatus. GENERAL PRECISION LABORATORY, Inc. June 9, 1949. [June 10, 1948] No. 15438/49. Class 118 (ii). A depth sounder comprises a pulse generator for generating periodically recurring electric pulses only certain of which, occurring at regular intervals, are used to initiate the transmission of acoustic pulses and means for receiving pulses and indicating depth only under control of pulses received between the transmitted pulse and the next following electric pulse. In an embodiment of the invention used in a depth finder of the type described in Specifications 644,433 and 644,456 the pulse generator comprises a blocking oscillator 11 the repetition rate of which may be adjusted by the tap 23 on potentiometer 18. The power pack 12 as shown includes a battery 13 and vibrator 14. The pulses generated are amplified by valve 28 and then applied simultaneously to the grids of gas discharge tubes 32 and 33. If the screen grid and anode potentials are sufficiently high the generated pulse will fire tube 32 and discharge condenser 38 through magnetostriction transmitter 39 to produce the transmitted pulse. Firing tube 32 reduces the screen grid and anode potentials and discharges condenser 41 which recharges through resistor 43 connected to the anode whose potential is itself increasing owing to the recharging of condenser 38. As long as the potential of the screen grid is below the critical potential the tube 32 will not fire again and thus transmitter 39 can be arranged to operate only on every third or fourth generated pulse. A keying rate indicator 48 is provided having five indicating reeds, the centre of which is timed to the correct frequency. Adjustment of contact 23 enables this frequency to be obtained. The echo pulses reaching receiver 51 are converted into electrical impulses which pass to a three stage amplifier 54, 56, 67. Blocking of valve 54 is provided for each generated pulse by the connection of its grid 57 to the anode of discharge tube 33 so that the directly transmitted wave does not affect the 'receiver indicator. The gradual charge of condenser 63 associated with the connection provides a corresponding increase in gain of valve 54 so that weaker echoes from greater depths receive greater amplification. Potentiometer 66 adjusts the gain level of valve 54 and is adjusted to avoid cross talk due for example to reverberation of the joint housing of units 51 and 39. The timing circuit comprises an Eccles-Jordan trigger circuit comprising valves 69 and 70 with a meter 86 connected in the anode circuit of valve 69. The meter 86 indicates the average current flow in that anode circuit, the valve 69 being made conductive by the transmitted pulse and cut off by the echo signal or, if this is not received first, the next generated pulse from unit 11. Switch 83 has three positions, one to check the battery, one to regulate the current flow through tube 69 when conducting, which may be done by potentiometer 91, and a depth indicating (normal) position.

Abstract: 1,003,900. Thermonuclear apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. April 16, 1964 [July 12, 1963], No. 15798/64. Drawings to Specification. Heading G6P. In a thermonuclear fusion device a high temperature gas plasma is confined between magnetic mirrors and is stabilized by the injection, into the magnetic confinement zone, of plasma particles of a type different from those forming the plasma. The added particles may be injected perpendicularly or tangentially into the plasma so as to stabilize specific regions of the fusion zone. In the embodiment described, in which hydrogen was employed as the thermonuclear fuel, tritium was injected into the plasma along a path perpendicular to the plasma axis. The stabilizing action of the arrangement is caused by the adjustment of the mean or effective particle orbit radius produced by the added plasma components. The orbit radius is shown to vary as a function of the density, mass number, charge and temperature of the plasma constituent particles. Specification 931,076 and U.S.A. Specification 3,152,959 are referred to.
