Title: Improved process for scaling tubes
IPC: B21C43/00
Filed: 1933-11-29
Abstract: 418,712. Scaling tubes &c. TRAUT, R., 69, Friedrichstrasse, M³lheim, Ruhr, Germany. Nov. 29, 1933, No. 33381. Convention date, Jan. 14. [Class 83 (iv).] Heated tubes or bars c are passed through dimensioning rolls a and then into a funnel h where they are sprayed with an annular spray of water to remove scale. A tube enters the guide f and raises the lever s of a switch r which energizes an electromagnet q which opens a valve o so that pressure water is supplied from the pipe p to the branch pipe n and is sprayed through the annular gap on to the tube, the inclination of the spray being such that some water enters inside the tube end also. The water and scale is discharged through the outlet m. The valve o may also be opened by the lever s either directly or by hydraulic or pneumatic means. The water pump may be driven by gearing from the rolls a. The valve o may also be opened by compressed air or water relay actuated by the passing bar or directly by the lever s itself. The size of the annular gap for the water is variable by screwing the nozzle k nearer to or away from the casing i. The Specification as open to inspection under Sect. 91 states that rolling is effected at about 850 C. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in elevator door operator
IPC: D06M13/402
Filed: 1931-02-24
Abstract: 374,073. Operating and locking lift cages and doors. WAYGOODOTIS, Ltd., 54, Fetter Lane, London. - (Otis Elevator Co.; 260, 11th Avenue, New York, U.S.A.) Feb. 24, 1931, No. 33382. Divided on 374,066. [Class 78 (iii).] In an electric lift-gate operating mechanism, the circuit of the hoisting motor is opened unless the gate is closed and the landing door fastened, and the opening of the hoisting motor circuit to stop the cage at any floor automatically initiates the opening of the cage gate. In Fig. 1 the gate 26 is operated by a lever 28, which is moved by a motor-driven crank 24 and rod 30. The lever operates limit switches 39, 40, by means of adjustable abutments, and also opens a switch 56 in the hoisting motor circuit unless the gate is closed. Also connected to the lever 28, by a chain, is a cam 70, which is lowered when the gate is opened, to operate a landing-door latch 62 carrying a contact 70 in the hoisting motor circuit. In the control circuit shown in Fig. 7, the opening operation is initiated by a push button 44, which energizes a relay 45, through limit switch 39, to complete a circuit shunting the button through contacts 46 and a circuit for the motor 18 through contacts 47 and resistance 42. The closing operation is similarly effected by pushbutton 48 and relay 50. In addition, the opening operation is automatically initiated when the cage stops at a floor by means of a relay 51 which, when de-energized by opening the lift control circuit, closes a circuit shunting the pushbutton 44 to energize the opening relay 45 ; the contact 55 of relay 51 is conducting on its upper surface only, and electrical connection is thus made by the armature 49 only when the latter is falling ; the contact 55 is hinged, and is spring-biased to the normal position.

Title: A portable apparatus for sandblasting, scouring or abrading surfaces of ships, bridges, buildings or the like
IPC: B24C3/06
Filed: 1929-11-05
Abstract: 332,849. Bailey, B. M. Nov. 5, 1929. Washing or cleaning by use of sand and abrading- agents. - A portable apparatus for scouring &c. the surfaces of buildings &c. by means of a blast of air, steam or other fluid and sand, grit, metallic grit, &c. consists of a casing a having a handle b and formed with a pipe c connected to a source of negative pressure and leading to a groove d at the front of the casing. This negative pressure is utilized to form a seal between a grooved rubber ring g, carried by a mouthpiece e, with passages, j, k therein, and the surface being scoured, the part e being secured to the casing by a clamping ring f. An opening at the rear of the casing is closed by a block m pivoted to the casing at n, bearing against a resilient gasket o, and carrying a plate p on which are mounted two nozzles q and, by means of wings s, two jet tubes t in alignment with the nozzles. The block m has a tubular arm portion u with an inlet v for pressure fluid, and also has a valve chamber wand a tubular extension x with a seating y, which may be closed by a spring pressed valve z operated by a plunger 11 in the handle b provided with a thumb button 12. In the chamber w is a spring-pressed valve 14 which moves, when the valve z is closed and the ring g is pressed up to the surface being worked, under the influence of the negative pressure to admit pressure fluid to the nozzles. A baffle plate 18 with openings therein is spaced from the top of the casing, and above the baffle are openings 19 leading, through passages 20, to a filter bag 22. The abrasive 24 is placed in the body of the casing, and in operation, the blast operates on the surface within the ring g, the block m being rocked by pressure on the button 12 to move the tubes and thus sweep the blast upwards. Spent abrasive falls back into the casing, lighter particles passing out to the bag 22. If the seal formed by the ring g is broken or the button 12 be released, the valve 14 closes and shuts off the blast. The mouthpiece e may be shaped according to the work to be performed, for example, for working in corners or on stepped plates; rollers may be fitted to the mouthpiece where great adhesion is not required. An observation window 25 is provided. According to the Provisional Specification, the pressure fluid is conveyed through a valve to a chamber containing jets arranged to create a partial vacuum in the chamber, and the outlet of the chamber is connected to a series of jets pivotally mounted in a second chamber containing the abrasive and having an orifice pressed against the surface under treatment, and sealed by a perforated cushion connected to the first chamber or to an exhausting pump.

Title: Improvements in and relating to pulse modulators
IPC: H03K3/543
Filed: 1954-11-23
Abstract: 757,477. Delay lines. ELIE, L. M. Nov. 23, 1954, No. 33950/54. Class 40 (8). [Also in Group XL (c)] A delay line for use in a pulse generator (see Group XL (c)) comprises a cylinder 11 of conductive metal covered by an insulating layer 12 on which is wound a coil of wire 13. One terminal of the coil 13 is connected to the line 15 and the load 4 is connected via a line 14 to the metal conductor 11. By this means a line of low characteristic impedance is obtained since the inductance of the coil 13 is reduced by the shorted turn constituted by the metal cylinder. In a modification shown in Fig. 4 the coil 13 wound on an insulating winding 12 covering a metal cylinder 11 is covered by a further insulating winding 16, a further metal cylinder 17, an insulating winding 18 and an outer coil 19. The ends of one side of wires 13 and 19 are connected in parallel as are the metal cylinders 11 and 17. Ry this means a line of very low impedance is obtained. The number of metal cylinders and insulated coils may be increased beyond two and the metal cylinders may be replaced by a tube of insulating material metallized on the inside or outside. The metallization may be two layers of bare conductor wire wound with contiguous turns one on either side of the insulation one of the windings thus constituting the coil of the delay line and the other conductive cylinder.

Abstract: 376,175. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Barden, W. S. ; 289, Vanderbilt Avenue, Stapleton, Staten Island, New York, U.S.A.) Dec. 9, 1931, No. 34184. Convention date, Jan. 10. [Class 40 (v).] Weak heterodyne interference, particularly the beat note or " whistle " caused by one of two common-wave transmitters drifting off the allotted frequency, is eliminated by a piezoelectric crystal shunted across the input to the second detector of a superheterodyne receiver. Owing to its sharp resonance, the crystal has no appreciable effect in cutting the sidebands of the desired programme. As shown in Fig. 5, the crystal 3 is shunted across the circuit 7, 8 coupling the intermediate-frequency amplifier IFA to the second. detector D2. Both the crystal and the circuit 7, 8 are tuned to the intermediate frequency, a resistance 10 serving to broaden the response of the circuit 7, 8 so as to cover the desired side-bands. In order to enable the same crystal to eliminate an undesired beat note of any frequency within 200-5000 cycles of the signal frequency, the local oscillator LO is adjusted, by means of a vernier control to make the beat note coincide with the crystal crevasse. For instance, if the heterodyne note is 500 cycles below the desired carrier, the latter is located at B, Fig. 6, whilst if the beat note is 500 cycles above, the desired carrier will be situated at A relatively to the crevasse.

Filed: 1964-08-21
Abstract: 1,072,479. Hydraulic jacks. HYDRAULIK LEIPZIG, VEB. Aug. 21, 1964, No. 34337/64. Heading B8J. [Also in Division F1] A plurality of piston-cylinder devices 2 for raising and lowering a load support member 15 by a plurality of reciprocating movements thereof is controlled by an hydraulic system comprising main and auxiliary pumps 1, 7 for each device and hydraulic locking cylinders 19, 17 controlled by limit switches 16, 23 and adapted to lock and unlock the support member 15 to a fixed structure and lock and unlock a connection between the support member 15 and a cross member 13. To raise the load support 15 the locking cylinders 17 engage rods 14 carrying the support 15, the locking cylinders 19 are disengaged and the main pumps 1 each deliver through an associated changeover valve 3 and non-return valve 10 to extend their pistoncylinder device 2 to raise the support 15. When the maximum lifting stroke has been achieved and each of the limit switches 23 has been actuated the pressure in lines 18 is released to cause the locking cylinders 19 to look followed by unlocking of the cylinders 17. The load is thus entirely supported on the piston and cylinder devices 19. The piston-cylinder devices 2 are then retracted by pressurizing a pilot line 21 to open non-return valves 9, 11 so that hydraulic fluid drains through an adjustable throttle 22 to a tank 4. After all of the piston-cylinder devices 2 have contracted limit switches 16 are operated to change over the locking cylinders 17, 19 and the valve 3 to initiate a second lifting operation. To lower the load support non-return valves 10 are operated so that hydraulic fluid exhausts at a controlled rate from each piston-cylinder device through the associated change-over valve 3 and the pump 1. At the bottom of the lowering stroke the switches 16 are actuated to cause the cylinders 19 to again support the load support 15. The consequent fall in pressure in the pistoncylinder devices causes the pressure switches 20 to operate and when all have been operated, the valves 3 and the cylinder devices 17 change over. The pumps 1, 7 thus return at high speed the piston-cylinder devices to the extended position for a second lowering.
