Title: Electromagnetic compensation weighing apparatus
IPC: G01G7/04
Filed: 1976-05-06
Abstract: 1502528 Weighing with electromagnetic compensation METTLER INSTRUMENTE AG 6 May 1976 [18 Nov 1975] 18665/76 Heading G1N Apparatus for this includes means for carrying a load to be weighed, a permanent magnet system with an air gap containing a compensation coil, as 32, 33, means for dividing the compensation current supplied to it by generator 54 or 70 into a first portion compensating substantially only the preloading of the apparatus, and a second portion, which is periodically conducted to the coil for a time proportional to the load, controlled by a control circuit with a switch 60, and provides compensation for substantially only said load, a counter 64 or 80 of constant frequency pulses during the load-proportional time feeding a digital display 48 representing the weight of the load. Sensor circuit 42, which may employ a differential capacitor, feeds a control signal via amplifier 50 to be compared with a sawtooth voltage initiated by oscillator 56 in pulse length modulator 52, which simultaneously causes electronic switch 60 to open and, when the sawtooth voltage equals the control signal, closes it, current from the constant current source 54 only passing through coil 32 when it is open. During this time gate 62 admits clock pulses from oscillator 56 to counter 64. The steady current through coil 33 compensates the preloading. Coils 32 and 33 may be on a common former. In the embodiment of Fig. 3 (not shown) there is no coil 33 and an adjustable resistor is connected in series with switch 60 and in parallel with coil 32. In the embodiment of Fig. 4, constant frequency pulses from oscillator 70 pass to coil 33 continuously and to coil 32 intermittently and via frequency divider 74, periodically activate resetter 82 and set flip-flop 76, so that the pulses are gated to counter 80 and switch 60 opens until an equilibrium signal from sensor 42 causes flip-flop 76 to close it and to shut gate 78. Alternatively switch 60 can be wired to act as a changeover switch between coil 32 and a substitute load.

Patent GB-154277-A (GB)
Title: Improvements in balancing devices for aircraft
IPC: B64C1/00
Filed: 1919-07-28
Abstract: 154,277. Munyard, A. R. July 28, 1919. Steering and balancing.-In balancing-devices for aeroplanes comprising power means actuating the controls through electro - magnetic clutches controlled by a gravity switch, the switch comprises two separate inclined compartments each containing a drop of mercury or other rolling conductor, and the control planes, when actuated, close an auxiliary switch which reverses the power actuation of the control planes as the machine approaches the normal position. Figs. 1 and 2 show the gravity switch comprising compartments 1, 2 adjustably pivoted at 8 and formed with conductors 3, 4, 5 and 3<1>, 4<1>, 5<1> over which roll drops 6, 6<1> of mercury. The ailerons 9, 10 are operated by cables 13, 14 wound on drums 15, 16 and connected to a hand-lever 12. The drums are adapted to be geared to continuously-driven bevel-gear 20, 21 by clutches 18, 19 operated by solenoids 17, the outer coil 22 or 24 of one or other of which is energized when the machine inclines sufficiently to bring the mercury 6 or 6' into contact with the conductors 3, 4 or 3<1>, 4'. The ailerons are thus adjusted oppositely, and the one which moves downwards brings a switch 29 or 29<1>, Figs. 1 and 3, from a contact 33 to another contact 34, whereupon, when the machine is restored sufficiently to bring back the mercury 6 or 6' to connect the conductors 3, 5 or 3', 5', a circuit is completed through the inner coil 25 or 23 of the other solenoid, so as to produce a return movement of the ailerons. The switches 29, 29<1> are connected to the ailerons by rods 37, Fig. 3, fitted with springs 38, 39, and the automatic action of the switches may be ensured by means of spring-returned catches 40, 41, which are lowered at the required moments by cords connected to the ailerons. The handlever 12, when actuated for adjusting the ailerons, opens a switch to disconnect the electro-magnetic apparatus; or mechanical means attached to the lever may prevent the solenoids from putting the clutches in gear, the lever being returned to normal by springs. Similar apparatus controlling the elevators may be provided for longitudinal balancing. A brake may be fitted to maintain the control planes in the raised or lowered positions for the requisite length of time for righting the machine. A copper ball or other rolling conductor, containing, if desired, viscous liquid to damp its movements, may be used instead of the mercury 6, 6'.

Title: Roll groove milling machine
IPC: B23C3/34
Filed: 1962-05-16
Abstract: 959,127. Machining rolls. BLAW-KNOX CO. May 16, 1962 [June 22, 1961], No. 18841/62. Headings B3B, B3K and B3T. A method of machining circumferential grooves in a set of mill rolls in which the rolls, complete with their housing are located on a frame in substantially the same position as they occupy in use, comprises rotating the rolls about their axes and bringing into cutting engagement therewith a milling cutter rotating about an axis transverse to the roll axes. The rotating cutter is movable into and out of engagement with the rotating rolls. The machining operation is effected by apparatus which comprises a frame 1 in two portions 2 and 3. Portion 2 slidably supports a carriage 4 carrying a rotatable spindle 5 with a milling cutter 6. Portion 3 carries the mill roll housing 7 with mill rolls 8 and 9. Alignment of the rolls in relation to the cutter is effected by packing shims at the housing supports 51, 52. To prevent axial movement of the rolls in the housing 7, an auxiliary supporting member 25 is fixed to the frame 15. Vibration of the rolls during machining is prevented by a hardwood wedge 41, Fig. 5, being forced against the rolls on the opposite side to the cutter 6. The cutter and rolls are provided with independent power drives of known type and power means is also provided to rapidly advance the carriage 4 to bring the cutter 6 to a predetermined position adjacent the rolls and for rapidly retracting said carriage at the end of the machining operation. This fast traverse is controlled by an automatic stop 79 which stops the traverse when the predetermined location is reached. Further, the stop 79 may also incorporate a gauge block 80 to limit the movement of the cutter between the rolls. The cutter and rolls are set in motion and the carriage advanced to its predetermined position, the finish machining operation being effected manually by feeding the cutter to its appropriate position depending on the form of circumferential groove required in the rolls. When this machining operation is completed, the carriage 4 is rapidly retracted, the roll drive stopped and the wedge 41 removed. An auxiliary machining means 92, with cutting tools 98 mounted therein, is provided to trim the outer edges of the resulting grooves in the mill rolls. By manipulation of controls 95 and 97, the cutting rolls round off or otherwise trim the edges of grooves 10 and 11. The rotation of the rolls being at a higher speed than for the previous operation. The completed form of the circumferential grooves may be determined by the position of the cutter 6 in respect to a vertical plane defined by the roll axes. The amount of offset determines the extent by which the final configuration varies with the true circular form. The tool marks produced on the rolls by the machining operation provide an improved bight on the work being passed during operation.

Title: Improvements in and relating to control bands or cards for use with statistical apparatus
Filed: 1931-07-01
Abstract: 390,525. Statistical apparatus. SENKEL, R. and DUEBALL, E., 8, Werftstrasse, Berlin. Julv 1, 1931, No. 19034. Convention date, July 1, 1930. [Class 106 (i).] A control band or control cards for use with apparatus for dealing with accounts whereby entries made on the band &c. can be computed with previous entries on account cards (balance cards) and the new amount transferred to the account cards has groups of perforations for each item representing the designation numbers of the accounts to which the item is to be credited or debited, the item value, and preferably also particulars in code of the entry. Each group comprises a plurality of rows of perforations h, i, k, l, as shown in the Figure, disposed one above the other and each subdivided, for the denominational values or code letters, into groups each having nine hole positions. Specifications 313,620, [Class 106 (i), Calculating &c.], and 389,103 are referred to. The Specification as open to inspection under Sect. 91 comprises also a method for utilizing the band whereby a selector mechanism receives the account designation number and compares that number with the number on the account cards as they are advanced through the machine. The action being such that the card is arrested when the numbers agree whereupon the card is moved to a printing position and is there acted upon by a sensing mechanism to transmit the amount (old balance) perforated in the card to a totalizing-counter mechanism. The control band is then sensed and the new item transmitted to the totalizer. The total (new balance) is then transmitted by zeroizing the totalizer to a printing and perforating mechanism and transferred to the next free line on the card. From the rows of perforations in the account cards the debit and credit items relating to the account can be calculated and balanced. All the entries on the control band relating to a particular account may be totalized and perforated individually on the account card. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in electrical insulating materials
IPC: H01B3/28
Filed: 1928-07-04
Abstract: 320,370. Smith, W. S., Garnett, H. J., Dean, J. N., Habgrood, B. J., and Channon, H. C. July 4, 1928. Indiarubber, preparation of; compositions.- Rubber is treated with a substance to cause it to swell; treated to convert normally water-insoluble nitrogenous constituents by hydrolysis into water-soluble compounds, and washed to remove these compounds, to produce a material suitable for use as an insulator for submarine electric conductors. The swelling agent may be a substance which acts on the protein, such as glycerol or other hydroxy compounds such as glycol or acetin, or it may be a rubber solvent such as benzene or toluene. Hydrolysis is preferably produced by the action of water at high temperature. The process may be carried out by heating rubber with a mixture of glycerol and water, to a suitable temperature, say 150‹-250‹C. preferably with stirring, or the rubber may be heated with glycerol, or exposed to the vapour of benzene until it has absorbed 10 per cent of its weight, and then treated with super-heated water or steam. The resulting product is washed and preferably stabilized by addition of an antioxidant such as p amino phenol. For the insulation of submarine cables, the purified rubber is preferably mixed with gutta or balata which may be treated as described in Specification 307,390. It may also be used in the compositions described in Specifications 322,208 and 328,025.

Title: Improvements in automatic brakes for talking machines
IPC: G11B17/02
Filed: 1929-06-24
Abstract: 335,558. Gramophone Co., Ltd., and Clark, G. F. June 24, 1929. Stopping.-Automatic stopping mechanism for gramophones comprises a pivoted lever 10 which is, movable by the sound-arm 6 so that, when the playing of a record is completed, the lever is caused to move from the stationary position it occupies during playing of a record to another position in the path of a member moving in conjunction with the turntable or other rotating part of the machine. This member imparts a thrust and a secondary movement to the pivoted lever to effect the stopping operation. The engagement of the pivoted lever with the member moving with the turntable &c. serves to retard the turntable, and the secondary movement of the lever is adapted to open an electric switch in the motor circuit. The lever 10, pivoted at 11, moves within limits determined by stops 12, 13, and is provided with a pin 9 engaging the forked end 8 of a lever 7, which is pivoted at 4 and held in frictional engagement with another lever 3 also pivoted at 4, The lever 3 is engaged by a pin 5 on the sound-arm 6 so that, during playing of a record, the lever 3 and sound-arm 6 move together and the lever 10 is held against the stop 12. When the end of the record is reached, the direction of movement of the sound-arm is reversed by means of an eccentric groove in the record, and the levers 3, 7 move in clockwise direction. The end 19 of lever 10 then moves into the path of a series of radial projections 18 on a frictional sleeve 15 on the turntable boss 14, and thereby retards the turntable. The resulting secondary movement of the lever 10 rocks a pivoted plate 29 on which the lever 10 is pivoted, and this causes a roller 33 on such plate to move from a recess 27 in a pivoted member 25 to a recess 28. This movement of the member 25 causes the spring contact 22 of the switch 23, which is in the circuit of the driving motor, to open. The lever 10 has an extension 34 which co-operates with a roller 35 on the lever 3 so as to re-set the device as the sound-arm is moved outwardly. Specification 316,731 is referred to.
