Title: Rotary impact tool
IPC: B25B21/02
Filed: 1953-11-19
Abstract: 738,951. Slip clutches. CHICAGO PNEUMATIC TOOL CO. Nov. 19, 1953 [Jan. 5, 1953], No. 32096/53. Class 80 (2). [Also in Group XXII] A rotary impact tool comprises a rotatable anvil 37, having at least one jaw 38, resilient means 54 interposed between a driving spindle 30 and a hammer 40 to urge the hammer towards a normal position adjacent the anvil, and a driving connection between the spindle and hammer which constrains the hammer for relative helical movement when it is displaced from the normal position but permits independent circumferential movement when the hammer is in the normal position. A shaft 28, driven by a pneumatic or electric motor, rotates the spindle 30 through planetary gearing 24, 31. The rotational movement is transmitted from the spindle 30 to a cam sleeve 44 by balls 46 running in grooves 45 in the spindle. The rotation of the cam sleeve 44 is transmitted to the hammer 40 by balls 49 riding against surfaces 50H, Fig. 16C. There is a circumferential lost motion of 40 degrees between the spindle and cam sleeve represented by the portions 45C, Fig. 16C, the slots 45 and the portions 470 of recesses 47 in the sleeve. A further lost motion of 60 degrees exists between the cam sleeve and hammer represented by the portions 480 of recesses 48 in the sleeve and portions 500 of recesses 50 in the hammer. The lost motion ensures that the hammer delivers a blow to the anvil jaws 38 when it is travelling at its maximum speed. When the motor is reversed, for unscrewing a nut, the parts at first assume the positions shown in Fig. 16A. Thus the cam sleeve 44 forms, in effect, a part of the spindle when screwing-up and a part of the hammer when unscrewing.

Title: Improvements in or relating to soldering irons
IPC: B23K3/03
Filed: 1946-10-30
Abstract: 630,875. Electric soldering-irons. STANDARD TELEPHONES & CABLES, Ltd., and FRANKTON, W. J. Oct. 30, 1946, No. 32235. [Class 39(iii)] [Also in Group XXXV] The head or tip 1 of an electric soldering iron is heated by a thermistor heating element 2 to give automatic control of the temperature of the iron. A helical spring 4 compressed between the thermistor 2 and a plug 5 maintains the thermistor in close contact with the inner wall 3 of the hollow tip 1. The thermistor may have a positive or negative temperature coefficient and in the latter case is used in series with a suitably chosen impedance (see Group XXXV). In an example, the impedance is matched to the value of the thermistor at a point midway between the room and working temperature and any small change in temperature produces a much' greater change in the opposite sense in the wattage input thereby tending rapidly to restore the temperature to its stable value. Specification 555,563, [Group XXXVI], is referred to.

Filed: 1977-08-04
Abstract: 1529779 Fractionating gas mixtures AGA AB 4 Aug 1977 [13 Aug 1976] 32680/77 Heading B1L An apparatus for fractionating a gaseous mixture having at least two components, e.g. air, comprises a bed 21 of adsorbent material, e.g. a zeolite, capable of adsorbing one of said two components under elevated pressure and of desorbing it when the pressure is decreased; a cylinder 10, which acts as a compressor, having a reciprocating piston 11 for alternately forcing the gaseous mixture from inlet 17 into the bed and removing gas from the bed by suction, the cylinder chamber communicating directly to the bed 21 via pipe 19 which allows free gas flow in either direction; a collection chamber 22 for unadsorbed gas, communicating via controllable valve 24 with a gas outlet line 26; and a controllable outlet valve 28 communicating with the bed end of the cylinder chamber for the outlet of desorbed gas. In use, air is forced by an upward piston stroke into bed 21 wherein nitrogen is adsorbed and oxygen-rich product collects in chamber 22, valve 24 being closed. The pressure in vessel 20 rises until, at a predetermined pressure, valve 24 opens for removal of oxygenrich product. When the pressure in vessel 20 drops below a predetermined value valve 24 is re-closed. Meanwhile valve 28 (operated by camshaft 24 connected to piston 11) is opened to allow exit of the desorbed nitrogenrich gases sucked off by the piston downstroke. Trapped oxygen from chamber 22 assists in backflushing the adsorbent bed. As the piston approaches the bottom of its chamber valve 28 is closed, and then, on the commencement of the next upward stroke, valve 35 (operated similarly to valve 28) is briefly opened to allow flushing of the piston chamber with incoming air.

Title: Improvements in or relating to the heat treatment of material of synthetic linear polymers
Inventor: BUCHAN JAMES
IPC: D06C7/02
Filed: 1955-11-16
Abstract: Filamentary material of a synthetic linear polymer is heat-treated by passage through a bath containing molten Wood's metal or other low melting-point alloy upon the surface of which is maintained a liquid film of an inert high-boiling organic compound of silicon.  The term filamentary material is intended to include yarns, threads and cords, or any of these materials in fabric form, and the process is particularly applicable to polyesters and polyamides.  The heat treatment may be a combination of hot stretching and setting. Filamentary material may be passed substantially horizontally and at controlled tension through the bath which, in the case of polyhexamethylene adipamide, may be maintained at 160-240 DEG  C.  A silicone oil may be used as the organic silicon compound.  The film on the metal minimizes oxidation, thus enabling relatively long baths to be used.

Abstract: 985,412. Ion pumps. VARIAN ASSOCIATES. Sept. 13, 1961 [Oct. 6, 1960], No. 32864/61. Heading H1D. A glow-discharge getter-ion vacuum pump has a cellular anode 23 disposed between two parallel cathodes 22, the cathodes being spaced from each other by a value between 1.15 inch and 1.35 inch and the cathode-anode spacing being within the range 0.2 inch to 0.35 inch. A method of selecting the electrode spacing comprises the steps of (a) determining the intrinsic pumping speed of a single cellular compartment as a function of the cathode-anode spacing or of the compartment height; (b) determining the actual pumping speed at the entrance of the cathode-anode region for said array of distributed cellular compartments as a function of the intrinsic speed of a single cellular compartment and therefore as a function of the cathode-anode spacing or compartment height; (c) plotting the actual pumping speed at the entrance to the cathode-anode region as a function of the cathode-anode spacing or compartment height; and (d) selecting the cathode-anode spacing or compartment height which produces the desirable usable pumping speed for the glow discharge apparatus. Alternatively, step (b) is replaced by the steps (b1 determining the actual pumping speed into the array of cellular compartments as a function of the cathodeanode spacing or compartment height, and (b2) determining the actual pumping speed at the entrance of the cathode-anode region for the array of cellular compartments as a function of the intrinsic pumping speed of a singular cellular compartment and the conductance into the array of cellular compartments and therefore as a function of the cathode-anode spacing or compartment height. A formula is given relating the pump dimensions to actual pumping speed from which the pump dimensions for optimum pumping conditions may be determined.
