Title: Method and apparatus for forming cutting elements
IPC: B24D15/08
Filed: 1961-04-05
Abstract: 935,599. Grinding cutting edges. SUNBEAM CORPORATION. April 5, 1961 [Aug. 4, 1960], No. 12242/61. Class 60. The under-cut shearing teeth of an electric razor are formed transversely of a channelshaped element by the method of simultaneously engaging with the element all the spaced discs of a grinding wheel of truncated conical shape to grind one side of the teeth and repeating this procedure with the relative reversal of this or a similar wheel, end-for-end, to grind the other side of the teeth. An element 1 of the type shown in Fig. 1, is ground by the sequence of operations shown diagrammatically in Figs. 2 and 3, the multiple-discs 27 of a conical wheel making a first pass, as in Fig. 2, to form one series of under-cut faces and repeating with a reversed wheel as in Fig. 3 to form the opposite faces. After under-cutting, the outer face of the element is lapped to remove burrs and to sharpen the corners 10 and 11. In the machine shown in Figs. 6 and 7, two conical wheels 26, each having flexible multiple discs are mounted on opposite sides of a preferably rotary circular carrier 16 at the periphery of which the elements 1 are yieldingly supported by holders of the kind shown in Fig. 10, the elements being inclined preferably at 11 degrees to the axis of the carrier in a plane parallel thereto; the angle of under-cut is also preferably 11 degrees. The wheels 27 are mounted for adjustment to the required angle. Alternatively, the elements may be mounted on movable fixture means and reversed periodically, or on conveyer means moving the elements in a closed cycle. The carriage 16 is rotated by a motor 22 and belt drive 24 between cam-plates 35, Fig. 10, on which ride rollers 36 located at the ends of transverse pins 42. Contacting the pins 42 are cylindrical members 40 housing spring-urged plungers 39 which bear on the supports 38, 54 of the elements 1 being ground. As the rollers 36 leave the cam portions of the plates 35 the spring pressure is relieved and the elements may be removed from between the adjacent pairs of fixed mounting members 37, Fig. 11, by sliding them out from under the retaining tab 50 formed at the ends of the members 37 at the unloading zone. Atomized oil is fed under air pressure to heads 75, 76 to cool the elements during grinding by the high-speed rubber or like thin abrasive discs forming the grinding elements 27 of the wheels 26. A diamond-tipped dressing tool 18 is provided for each wheel mounted for movement parallel to their respective peripheries.

Title: Improvements in and relating to radio receiving circuits
IPC: H03D5/00
Filed: 1943-07-30
Abstract: 570,772. Valve circuits for wireless reception ; frequency modulation. MULLARD RADIO VALVE CO., Ltd., and RICHARDS, C. L. July 30, 1943, No. 12406. [Class 40 (v)] The audio-frequency stages of a radio receiver are arranged to be switched for the alternative reception of amplitude-modulated waves, frequency-modulated waves, or continuous-wave telegraphy. The incoming waves are fed from preceding stages into the grid circuit of a valve V1, the grid-cathode space acting as a rectifier and giving a signal voltage representative of amplitude modulation across a resistance R1 in the grid circuit, which voltage is led to the contact AM of the three-position switch S. Frequency modulation is detected by a phasing discriminator comprising coil Lp, tuned circuit Ls, Cs, and rectifier R2 arranged as described in Specification 567,813, the switch contact FM being connected to one end of the load resistance R3. For the reception of CW telegraphy, an oscillator valve V2 is energized by a switch H ganged with the switch S, and supplies local oscillations to the anode of the valve V1 to produce audio beat voltages at the contact CW which is connected to the resistance R3. A resistance and blocking condenser may be interposed between the anodes of valves V1, V2, Fig. -2 (not shown). This resistance may assist in providing necessary damping for the circuit Ls, Cs. In a further modification, Fig. 3 (not shown), the local oscillation from V2 is fed to the grid of the valve V1 and CW as well as AM signals are taken across the resistance R1. AVC voltage is derived in part as shown in Fig. 1, but arrangements are provided by which during CW reception another AVC voltage is derived from the slider of an output potentiometer.

Title: Method of and apparatus for facilitating the erection and tensioning of fencing wire
IPC: B65H75/40
Filed: 1951-05-30
Abstract: 705,690. Erecting fences. SALTER, S. H. Sept. 1, 1952 [May 30, 1951], No. 12711/51. Class 45. [Also in Group XXXI] A method of erecting and tensioning fencing wire, comprises paying out wire from a reel rotatably mounted on a power-driven vehicle by driving the vehicle forwards, after having secured an unwound portion of the wire to a post, thereby laying the wire at the required height as the reel rotates, then holding the reel against rotation by reel engaging means and driving the vehicle slowly forward to tension the wire, stopping the vehicle and then securing the wire to the next post while the wire is maintained by the vehicle in its tensioned state. Apparatus for carrying out the method comprises a pair of bars 1, which are adapted to be bolted to the rear of a tractor and to which a square section bar 5 is bolted. The bars 1 have a plurality of holes 4 so that the bar can be bolted to them in a number of positions to enable the height of the wires to be adjusted. On the end of the bar 5 is a disc 6 and a spindle 7. A drum 8 for carrying the wire is rotatably carried by the spindle and it is retained in position by a detachable disc 9 and a cotter-pin 10. The drum is normally prevented from rotation by means of a spring loaded pin 11, secured in a housing 13, on the disc 6, the pin engaging the adjacent cheek 14 of the drum. A cord 15 attached to the pin enables it to be pulled away from the drum cheek when it is desired that the drum shall rotate.
Patent GB-848560-A (GB)
Title: Gas turbine fuel system
IPC: F02C9/16
Filed: 1957-04-23
Abstract: 848,560. Gas turbine plant. GARRETT CORPORATION. April 23, 1957 [April 26, 1956], No. 12886/57]. Class 110 (3). The fuel supply system for a substantially constant speed gas turbine plant having a compressor, a combustion chamber and a turbine comprises a fuel pump, speed responsive means acting on a by-pass for governing the speed of the turbine and a second by-pass conduit around the pump including a by-pass valve controlled by means responsive to a pressure differential in the fuel line between the fuel pump and the combustion chamber and to means responsive to compressor pressure. The invention is described with reference to a gas turbine plant comprising a centrifugal compressor discharging into a chamber surrounding the compressor containing a combustion chamber the combustion products from which pass through an inward radial flow turbine mounted on the compressor shaft. Fuel is supplied to the burners by a positive displacement pump around which are arranged two by-pass pipes. One of these pipes is controlled by a valve opened by flyweights where the speed of the turbine shaft exceeds a predetermined maximum value. The second by-pass pipe is controlled by a valve 19, Fig. 2, which is responsive to the rate of fuel flow to the combustion chamber, the compressor discharge pressure and the turbine exhaust temperature. Fuel from the pump passes through pipe 20, the adjustable orifice 49, chamber 46 and the pipe 21 to the engine. The pressure at the upstream side of the orifice 49 is communicated to the chamber 47 by the conduit 50. The pressure drop across the orifice acts on the diaphragm 44 which is urged thereby and the loading on the spring 45 to the left so that the push rod 43 engages the valve element 39. The valve element 39 controls the flow through the by-pass pipes 20, 23 and is mounted in a freed bushing 41. A head 40 of the element 39 engages the bushing 41. The valve element 39 is urged to the right by the pressure difference across a diaphragm 54. The chamber 53 is connected to the compressor discharge and the chamber 60 to atmosphere. The chamber 53 is partially defined by another diaphragm 51 which has a larger area than the diaphragm 54. The chamber 52 of the other side of diaphragm 51 is also connected to compressor discharge pressure through a restricted passage 57. Normally the pressures on each side of the diaphragm 51 are equal and the diaphragm is ineffective. The chamber 52 is connected by a passage 52a with a vent valve which is opened when the turbine exhaust temperature exceeds a predetermined value. This causes the pressure in the chamber 52 to drop and the diaphragm 51 will move the bolt 56 away from the valve 39. The pressure drop across the diaphragm 44 will then cause the valve 39 to move into an open position and so bypass more fuel and thus reduce the temperature. An adjustable spring 58 acting on the diaphragm 51 maintains the valve 39 closed during starting.
