Nov. 10, 1932, No. 31819. Convention date, Nov. 27, 1931. [Class 89 (iii).] A pliers-type stapling tool comprises a body part 15, which is formed from sheet metal with an integral handle 21 and with a mouth 22 to receive papers to be stapled. A clinching anvil 23 is fixed below the mouth 22. A housing 35 removably pivoted within the body 15 at 75 is formed of U-section from sheet metal with an integral head 41. The latter comprises spaced side walls 44, inturned top portions 45, Fig. 3, and front wings 47 which co-operate with a removable end member 42, Fig. 4, to define a driver guideway 55. The member 42 is also formed from sheet metal and is held to the head 41 by a pin 56. The front of the body 15 is closed by a removable cover 26, to facilitate assembly or dis-assembly of the housing 35. The latter houses a U-section guide 36 for a staple strip 64. The staples are fed by a pusher 65, Fig. 6, and a spring 71 encircling a rod 66, the rod being accommodated within the guide 36 and carrying a head 68, whereby it is bayonet-jointed to the rear end of the guide. A handle 81 pivoted at 82 to the body 15 is pivoted at its front end, by a pin and slot 86, 87, to an operating lever 80, which is pivoted to the body 15 at 83 and has a nose 79 which enters an aperture 78 in a driver 76, Fig. 8, the latter being reciprocable in the guideway 55. A spring encircling the pivot 82 has one limb 89 engaging the handle 81 and the other limb 90 engaging the housing 35 at a point forward of its pivot 75. When the handle 81 is pressed towards the handle 21, the spring 90 first forces the forward end of housing 35 down upon work placed within the mouth 22. The lever 80 then turns about its pivot, forcing the driver down to cut off and drive a staple. When the handle 81 is released, the lever 80 raises the driver, and also raises the housing 35 by engaging the portions 45 of the head 41. A lever 60 pivoted to the member 42, Fig. 8, is arranged to prevent entry of a second staple into the driver guideway before the first has been completely driven. The driver 76 is slotted to clear the lever 60, and the forward ends of the staple guide 36 and of a shear block 37 carried thereby are slotted to allow the necessary swinging movement of the lever 60. The staple pusher 65 is formed with a guiding lip 65b which slides in a slot in the housing 35. Specification 372,012 is referred to.

Title: Improvements relating to the distillation of liquids such for example as tar and oils
IPC: C10C1/04
Filed: 1920-11-17
Abstract: 180,347. Wilson, J. L. Nov. 17, 1920. Hydrocarbons, distilling; progressive evaporators; column stills.-In a continuous process of distilling liquids such as tar and oils, an inert permanent gas is blown through the liquid in the still, conveying the vapours through a series of fractional condensers, which also serve as preheaters for the liquid to be distilled. The liquid may be further preheated by passing through the pitch cooler. In a preferred form of apparatus the still c is divided by baffles i into compartments which each contain a hair-pin heating flue k and a perforated pipe supplying the inert gas, which may be flue gas. The vapours pass into the series of condensers b, which each consist of groups of vertical pipes immersed in the liquid to be preheated, which enters the jackets of the condensers in regulable proportions through the inlets o<1> and leaves by the outlets B, passing through the pipe p to the pitch-cooler d. The latter consists of horizontal tubes, through which the pitch flows from the still to the outlet s, surrounded by a jacket from which the tar passes to the still by the pipe q. The condensers and pitch cooler are placed around three sides of the still. A water condenser m<1> is placed after the series of condensers b, and any vapour arising from the preheated tar is led by pipe m to the condenser m<1> or to a separate condenser. The Provisional Specification also states that the inert gas may be either steam or permanent gas, and describes an apparatus in which the steam or gas is preheated in the pitch cooler, and admitted to the still through perforated pipes coiled round the heating-flues so that the gas impinges directly on these. A further supply of preheated gas may be admitted to the still above the surface of the liquid. If permanent gases are used they may be forced through the plant in a closed cycle by a compressor, which may also act so as to reduce the pressure in the still. A modified form of condenser is described consisting of a helical passage, in which the vapour ascends, surrounding a vertical downcast pipe. the whole being immersed in the preheating-vessel. The tar in this case runs through all the condenser jackets in series.

Title: Automatic electric tuning apparatus
IPC: H03J7/00
Filed: 1975-08-04
Abstract: 1511359 Stop on signal receivers; AFC arrangements SANYO ELECTRIC CO Ltd 4 Aug 1975 [17 Dec 1974] 32525/75 Headings H3Q and H3A In an automatic tuning apparatus having a tuning sweep of a voltage controlled variable reactance tuning means (VC, Fig. 1, not shown) stopped when the output from the tuning means reaches a predetermined level detected at 6, Figs. 2 and 3, and AFC applied to the tuning means from 13, 14 when the detected output reaches the predetermined level, on initiation of the power supply PS to the apparatus, a signal e having at least the predetermined level is provided for forcibly actuating the AFC for a predetermined time. After the power supply has been switched off a potential memory device MD stores the tuning voltage of the last station stopped at for so many hours. Due to drift in the memory device or variations caused by temperature the tuning voltage across the device MD can have drifted when the power supply PS is switched on again by PSW so that the amplitude of the IF signal is lower than that required by detector 6. This would make T7 conduct and via OR gate 15 would disable the AFC circuits 13, 14. However it is necessary for the AFC circuits 13, 14 to operate so as to bring the tuning circuit (VC) back to the station last stopped at. Therefore on turning on of the power supply T8 is delayed from conducting for the time (t 1  - t 2 ) determined by the RC time constant CR 3  to provide a pseudo IF signal e to the level detector 6 so that the AFC charge and discharge transistors 13 and 14 are allowed to operate and correct the tuning to the station last stopped at. The stop on signal tuning apparatus which which the circuits of Figs. 2 and 3 are used is disclosed (Fig. 1, not shown) and has upper and lower level detectors (115, 116) which reverse the charge and discharge of charge/discharge control circuit 119 so as to prevent damage to the potential memory device MD which has a solid state electrolyte. The tuning scan is started by a switch (111) which sets a flip flop 111F and is stopped by outputs from the IF level detector 6 (142) and level detector 10 (125) for the ratio detector (124) which reset the flip-flop 111F. If a signal which the tuning apparatus has stopped at fades then the output from the level detector 6 changes to make T7 conduct and disable via OR gate 15 the AFC circuits 13, 14 so that the station tuned to is not lost. The tuning voltage is connected to a LED frequency display (118). Specification 28735/75 is referred to.

Title: Improvements in ultrasonic detection apparatus
Inventor: ROTH WILFRED
IPC: G08B13/16
Filed: 1959-09-28
Abstract: 922,765. Magnetostrictive transducers. W. ROTH. Sept. 28, 1959 [Oct. 7, 1958], No. 32877/59. Class 40 (4). [Also in Group XXXVIII] A transducer for an ultrasonic control system (see Group XXXVIII) comprises an outer cylindrical casing 85 with a permanent magnet 87 attached to one end, the other end being closed by a member 89. A magnetostrictive tube 88 is attached to the member 89, and is surrounded by a coil 91. The member 89 is secured to the case by a flange 90 and is rigidly clamped by means of a cylindrical member 92 which is a quarter-wave length long at the operating frequency. The rear end of this member is free to move, so that the axial velocity at the other end is substantially zero, effectively clamping the member 89. The length of the cylinder is made less critical by arranging for it to function also in a radial mode of operation by making its circumference one wave length long. The tube 88 is arranged to have its half-wave resonant frequency slightly higher than that of the diaphragm 89 so that when the two are attached, the resulting resonance is between the resonance of the two separately.
