Title: Improved hand tool for cutting wood
IPC: B27G17/08
Filed: 1954-06-01
Abstract: 786,268. Chisels: handles. CROWHURST, J. Sept. 1, 1955 [June 1, 1954], No. 16193/54. Class 61. A tool for cutting floor boards comprises a cutting blade 5, a striking surface opposed to the main cutting edge 6 of the blade, a fulcrum member 8 adapted to engage the surface of the material into which the blade has been driven and a handle 3 for rocking the tool about the fulcrum member to withdraw the blade from the material. As shown the blade 5 is received between the cheeks of a blade holder secured to the handle 3, a pair of cheeks 10 on the fulcrum member engaging outside the cheeks of the blade holder and the assembly being secured by bolts 11. The lower surface 9 of the member 8 is of substantial width. The blade has a lateral cutting edge 7 which assists in clearing the gap made by preceding cuts. In a modification the fulcrum member is formed integrally with the handle. In another modification the vertical handle is replaced by a horizontal handle having a striking surface formed by a projecting boss. The handle has a double bend so that the portion of its length remote from the blade lies parallel to and spaced from the floor when the blade is completely embedded.

IPC: D06F73/00
Filed: 1948-06-18
Abstract: 646,889. Steaming garments. SHAW, J. C. June 18, 1948, No. 16427. [Class 138 (ii)] [Also in Group XIII] A garment steaming and drying apparatus comprises a base 10, Fig. 1, a hollow foraminous garment supporting form 12 mounted upon the base and provided with partition means 65, Fig. 7, dividing the space within the form into a plurality of chambers 66, 67, each open at its bottom, means for producing air flow through said chambers by way of their bottom openings, and means, such as a plate 68, effective while said air flow producing means is in operation for obstructing flow through at least one of said chambers. The form 12 is removable from and manually rotatable on the base and may be manually moved to an inclined position under control of a pedal 26, Fig. 2. By adjustment of a hand lever 48, air may be drawn through the form, and a garment supported on it, to the inside of the form, or heated air may be blown through the form and garment from the inside. Steam may be introduced into the form, under the control of a pedal 61, alone or to mix with the heated air. Forms, construction and mounting of.-A number of interchangeable forms of different sizes to fit different garments are provided. They are each formed of a hollow foraminous shell 13, Fig. 7, such as heavy wire screen or the like, over which is laid a smooth porous material 14 such as flannel or the like, terminating at the top in a neck-piece 15 and at the bottom in a flanged attachment ring 16. This ring is provided with rollers 18 supported on a ring 19 to allow the form to be rotated manually about its vertical axis. To facilitate working on the garment, the ring 19, together with the form, may be tilted about horizontal stub axles 20, Fig. 1, against the action of a spring 27, Fig. 2, in which position it is held by a catch releasable by the pedal 26. The ring 19 is situated at the mouth of a conduit 36 and is partially closed by the plate 68. Air or steam issuing from the conduit is thus directed inside that or those compartments 66, 67 of the form selected by its rotational position. Air supply.-Heated air is supplied to, or air is sucked from, the conduit 36 by a motoroperated fan 31, according to the positions of a pair of dampers 35, 41, coupled together and to the operating lever 48. The damper 35 determines whether the air supply shall be derived from the atmosphere through a port 34 or through the form and conduit 36. The damper 41 is correspondingly positioned to direct the exhaust from the fan through a steam-heated chamber 40 to the conduit 36 and form, or to atmosphere through a port 38, respectively. Steam supply.-Steam is admitted through a valve 58 and apertured dome 51 to the mouth of the conduit 36. The valve is opened by depressing the pedal 61 and is held in any one of a number of selected positions by a spring latch 63 releasable by a second pedal.

Abstract: 1509182 Converting circuits for television receivers COMMUNICATIONS PATENTS Ltd 14 April 1975 [17 April 1974] 16887/74 Heading H2F In a TV receiver, having a line scanning circuit including a commutating capacitor arrangement C4 supplied from a D.C. source C5B which includes a controlled rectifier THY1, means THY2 are provided for recovering energy from the commutating capacitor C4 of the line deflection circuit and returning it to the source C5B of D.C. voltage and further means, TR1 responsive to the failure of the energy recovery means for switching off the controlled rectifier THY1. In the TV receiver described the mains voltage LN is rectified by diode D and thyristor THY1 and feeds a smoothing circuit C5A, C5B, the output of which is passed via diodes D10, D11 and terminal X to the line deflection circuit comprising thyristor THY22 and commutating capacitor C4. An auxiliary winding W1 on the line output transformer LT5 provides positive and negative square waves at Y and Z. These are compared and used to control transistors TR3, TR2 which determine the conduction angle of the energy recovering thyristor THY2 so as to tend to maintain a constant voltage on C4 and hence constant scan amplitude. Under fault conditions, the pulse amplitude across R17 will increase, breaking down Zener diode D9, turning on THY2 so as to minimize the voltage at terminal X. If a fault occurs in THY2, an A.C. waveform will appear across R17 which turns on TR1 so as to block the gate signals on the rectifying thyristor THY1 and so inhibit its operation. Alternatively, a resistor may be included in the cathode lead of THY2 which normally provides a hold off bias for TR1.

IPC: A01K73/045
Filed: 1927-06-25
Abstract: 295,109. Hensman, W. June 25, 1927. Trawling-gear.-Otter boards are arranged to pass obstacles on the sea-bed more readily than is usual by connecting the towing warp h to the towing brackets or chains by a sliding or rolling connection such as a shackle p carrying a pulley or a sleeve over or through which the chain f passes. The chain f may be joined to a forward triangular bracket c and a rear similar bracket o, or its rear end mav be attached to the board itself. The rear end of the chain f may be free to move along the sides of the rear bracket o, for which there may be substituted a chain-loop. If, when in use, the forward end of the otter board meets an obstruction, the board fulcrums about that end and the towing warp connection moves towards the rear end of the board, thereby increasing its leverage and facilitating clearing the obstacle; as the board is drawn clear, the conditions of suitable equilibrium cause it to be quickly restored to its normal working condition. Specification 175,824 is referred to.

[Class 27] Articles stored in rows; coin action, mechanicalconnection.-Articles to be vended are stored in a number of horizontal rows 4 each pressed forward against an abutment 12 by a spring drum 10 about which is wound a draw-tape 11 anchored to the abutment. For each row there is an ejector 13 carried by a lever 15 connected by a cable 17 to an arm 19 loose on a shaft 20. Over each arm 19 is a coin receptacle 21 on a common support 22, extending between a pair of arms loosely mounted at either end of the shaft 20, and connected to a draw knob 25. A coin inserted in the slot of the row of articles selected is received by the corresponding receptacle 21, and transmits the movement of the draw knob 25 to one of the arms 19 which rocks the ejector lever 15 of the row selected to raise the foremost article above the abutment 12.
