Patent GB-472730-A (GB)
Title: Improvements in or relating to machines for attaching heels to boots, shoes and the like
IPC: A43D79/00
Filed: 1936-11-17
Abstract: 472,730. Hydraulic presses. RONNEBERG, E. Nov. 17, 1936, No. 31488. [Class 69 (ii)] [Also in Group VII] A machine for attaching heels to boots, shoes and the like, is provided with hydraulic mechanism which causes the boot &c. to be held firmly between a stationary anvil head and a nailing head and also causes the nails to be driven into the boot &c. The frame 1 carries a stationary anvil head 15 against which the nailing head presses the shoe. By means of a pump at the base of the frame, oil is circulated up a pipe 9, through an orifice 14 into a slide valve cylinder 13, and back to the pump via a return pipe (not shown). The cylinder 13 communicates with an oil tank 10 through a bent pipe 12 so that it is always full. Within cylinder 13 are two pistons 19 and 20 attached to a valve rod 7 operated by a treadle. When the piston 20 is in the position shown, the oil merely circulates up pipe 9 and down the return pipe. When, however, the treadle is depressed so that the piston 20 descends beyond the orifice 21, the oil is directed into a chamber 22 in which slides a thin walled cylindrical piston 27. As oil enters chamber 22 piston 27 rises, taking with it an interior piston 29 which is pressed against a stop 47 on the wall of the piston 27 by means of springs 30. Further depression of the treadle allows the oil to pass through the orifice 23 into a cylindrical chamber 25. The piston 29 is thereby raised relative to the piston 27, compressing the springs 30. The upward force of the piston 29 is transmitted to the nailing apparatus by a tappet member 31 and a push rod 32. The force exerted by the piston 29 is greater than that exerted by the piston 27 owing to its greater effective area. The pressure of the oil in the apparatus is indicated by a manometer 33 and is adjustable.. To prevent excessive loading of the machine, a throttling valve is provided, consisting of a screw 36 adjustable from the outside, which allows the oil to trickle from the chamber 25 by way of a narrow conduit 37, Fig. 4, which leads to a cylindrical space 38 in which a hollow piston 39, Figs. 3 and 4, can slide, while a compression spring 40 tends to maintain this piston in the position shown in Fig. 4. When the oil penetrates into the space 38, it moves the piston 39 and, at the same time compresses the spring 40, until the piston opens a direct channel 41 from the chamber 25 to the space 38. The piston 39 is thereby moved further on, and the oil from the chamber 25 escapes through the space 38 into the discharge pipe 24 leading to the cylinder 13. By adjustment of the screw 36, the time during which the machine is exposed to the maximum load can be predetermined. When the pedal is released the machine is ready to repeat the operation.

Abstract: 785,155. Blasting cartridges. BORGWARNER CORPORATION, and WELEX JET SERVICES, Inc. Nov. 7, 1955, No. 31756/55. Class 9(1) An explosive device more particularly for use in penetrating well casings comprises a hollow charge 4 in which is embedded a barrier 5 of inert material such as steel or other metals or non-metals. The charge 4, which may be TNT, or cyclotol is housed in a cylindrical casing 1 preferably of metal such as steel, cast, iron or aluminium or alternatively of non- metallic material such as synthetic plastics. A liner 2 fitted into the charge cavity may be of copper and is rounded at the apex 3, while the barrier 5 is of uniform thickness and is preferably a segment of a sphere, but may also be conical, paraboloidal, ellipsoidal or a flat disc. Behind the barrier, the casing 1 has a wall 8 shaped to conform with the barrier so that the layer 7 of explosive between the barrier 5 and the wall 8 is of uniform thickness. Coaxial with the charge a socket member 9 extends from the wall 8 and houses a booster pellet 12 between a detonating fuze cord 11 threaded through openings in the socket and the explosive 7 which extends into an opening 13 in the wall 8. On. firing the device, the detonation wave front in the explosive 7 is checked at the centre by the barrier 5 and passes to the main body of explosive through the annular gap 6 between the barrier and the casing whence it expands towards the axis of the device. A pressure pulse may, be set up in the barrier sufficient to detonate the central part of the explosive but with some delay. The peripheral wave front and central wave front will then merge together to give a wave front of definite pattern depending on factors such as thickness of the barrier and quantity of explosive in casing 1.

Generale de Constructions Electriques et Mecaniques (Als-Thom) ; 38, Avenue Kleber, Paris.) Nov. 16, 1933, No. 32005. Convention date, Nov. 17, 1932. [Class 39 (iii).] The welding electrode 4 in an arc welding system is fed by a motor 3 which, on closure of a push button 8 is energized through a switch 15 by the difference of the voltage of the exciter 2 of the main generator 1, and the voltage across the arc. A relay 7 energized by closure of the push-button 8 also effects closure of the main welding circuit at 6 and of a holding circuit at 15. When welding current flows in the main circuit, after drawing and striking of the arc, a switch 16 operates and energizes a coil 11 which moves a switch 10 so that the motor 3 is supplied with the arc voltage alone. A short circuit across a controller 13 in the field circuit of the motor 3 is also removed when the switch 10 operates. During starting, the motor 3 is, in effect, energized from the difference of the voltages of the generators 1 and 2 and moves the electrode 4 forward to strike the arc but during drawing of the arc it is energized by the difference of the voltage across the arc and that across the exciter 2. An additional contact 21 on the switch 10 is provided connected to a line 22 for supplying additional motors from across the exciter 2 in an automatic welding system where the work is fed forward. Specification 179,613, [Class 39 (iii)], is referred to.

Title: Monitoring circuit arrangements
IPC: H04B3/46
Filed: 1975-07-31
Abstract: 1522001 Monitoring voltage levels SIEMENS AG 31 July 1975 [21 Aug 1974] 32018/75 Heading G1U A monitoring system e.g. for signal levels in telecommunication systems, includes a two-transistor bi-stable trigger, which is operated by the conduction of a diode when the monitored level falls below a first reference, or by the conduction of a transistor when the monitored level exceeds a second reference. The bi-stable formed by transistors 195, 196 rests with 195 conducting when the levels applied to the inputs 6-8, are correct i.e. around -7À5 volts. If the levels at 6, 7 rise towards zero, the input diodes 157 or 155 begin to conduct at a level defined by the reference Zener 163, via resistors 73-78 and transistor 199. At this point, transistor 195 turns off and 196 comes on. If the level at input 7 falls negatively, eventually the voltage drop across diode 156 and the base-emitter junction of transistor 191 from the reference set by Zener 163 via resistors 73-76 and transistor 194 is sufficient to turn transistor 191 on, raising the voltage at the base of transistor 195 via resistor 49 and diode 158, with the results as described above. The state of the bi-stable 195, 198 is passed to an output stage providing momentarily grounded pulses on outputs 12, 13 and constant ground on outputs 15, 17. Two of the circuits shown are used to provide redundant protection to a telecommunication arrangement. To avoid signalling an alarm condition at the switching on of the apparatus when -12 volts is applied to terminals 9, 11, capacitor 130 charges up to this voltage and turns on transistor 193. This causes the base-emitter junction of transistor 192 to be forward-biased turning this on and making the base of transistor 195 negative, ensuring that this turns on and remains so until the capacitor 130 is fully charged and the apparatus is stable and set to monitor. Transistor 192 may also be turned on by applying earth on terminal 21 or operating push-button 215. Operation of an alarm signal by spurious signal level changes, is prevented by transistors 196, 197 and capacitor 133 as described in Specification 1522002.

Filed: 1928-11-02
Abstract: 315,381. Girard, P., and Petit, F. July 13, 1928, [Convention date]. Purifying waxes and mineral and tar oils.-In pressure cracking processes the low-boiling hydrocarbons are withdrawn and the residual asphaltic oil or unvaporised portion is subjected at ordinary or elevated pressure to a treatment. with an alkaline earth at a temperature above 300‹ C. but below that at which cracking would occur, to produce non-asphaltic products which are suitable for treatment in the cracking process and are returned thereto. The quantity of reagent employed is determined by multiplying the oxygen content of the product by a factor obtained by dividing the molecular weight of the reagent by that of oxygen. The residual portion may receive a preliminary oxidation treatment. Example. A pitch from a cracking plant and containing 3 per cent of oxygen was heated with quick lime at a temperature above 300‹ C. at ordinary pressure and produced 40 per cent of a liquid having a density of 0.870 and 2 per cent of gasoline. On distillation 88.5 per cent of the liquid passed over below 325‹ C. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the purification of asphaltic, bituminous, or resinous products including mineral oils, ozokerite, and other waxes, by treatment with an alkaline earth at a temperature of about 300‹ C.
