Patent GB-923126-A (GB)
Title: Improvements in or relating to combined abrasive and polishing structures
IPC: B24D18/00
Filed: 1959-07-28
Abstract: <PICT:0923126/III/1> An abrasive and polishing material 10 comprises a sheet 12 of flexible self-supporting material and a coating on at least one surface 14 comprising a layer 16 of a substantially equally flexible elastomeric composition and abrasive particles 20 capable of passing through a 500 mesh screen located within said layer, which layer is bonded to the sheet.  The sheet may be a film of an elastomeric material, e.g. a polyolefin such as polyethylene, the film being substantially 1 to 2 m. thick, or of regenerated cellulose, cellulose acetate, chlorinated synthetic rubber, vinyl acetate or nylon 6-6; a foamed layer of a natural rubber latex; leather of a soft and stretchy nature, e.g. glazed kid; wood; card or piece of twine; or a woven or non-woven fibrous synthetic material, e.g. non-woven nylon-acetate.  The abrasive particles, which may be capable of passing through a 600 mesh screen, may be of silicon carbide, emery or aluminium oxide, may be uniformly distributed throughout the layer which resiliently holds the particles in place. The layer may be composed of a cellulose lacquer or a flexible vinyl or silicone elastomer, e.g. vinyl butyl ethers, polychloroprene, styrenebutadiene, isobutylenes, acrylic esters such as poly-n-butyl methacrylate, butadiene-phenolicrubber composition, and may include plasticizers.  The material may be produced by applying a mixture of a liquid resinous material and the abrasive particles to the surface of the sheet, and heating the coated sheet to cause the resinous material to form a solid elastomeric coating holding the particles on the surface of the sheet.  The material becomes electrostatically charged during use and attracts dust and other particles from the article being polished.

Title: Winding regulation for spring mechanisms, especially clocks
IPC: G04C1/12
Filed: 1929-08-26
Abstract: 331,425. Bõuerle, T. Aug. 26, 1929. Winding - apparatus, hand and electric.-To prevent overwinding of a spring for driving a clock &c., the spring box c, Fig. 1, carries a regulating-device by which the winding- spindle a is locked when the spring reaches the required tension, and remains locked until the spring runs down an unvarying amount. The spring can then be rewound by hand or by an electric motor. The spring drives by a wheel e and is wound from wheel d fast upon spindle a, which carries a pin h adapted to mesh one tooth at a time with a pinion g freely carried on a pivot f on the box c. A frame k fast on spindle a carries spring-pulled pivoted levers o<2>, p, Fig. 3<a>. A pin i projecting from pinion g resting against a lug u<1> on lever o<2> prevents the spring from running farther down. In winding, frame k turns in the direction of the arrow, and pin i turns slowly in the opposite direction, missing lug u<1> several times until it comes up on the other side of lug u<1>, as shown in Fig. 3b. Lever o<2> then pivots until another lug u<2> upon it engages over one of a number of pins v on a fixed plate w, whereby the winding motion is stopped. At the same time, lever p slips behind lever o<2> and locks it in engagement with the spring wound. As the spring unwinds to drive the clock &c., pin i retraces its planetary eccentric paths until it strikes a pin t on lever p, moving that lever to allow lever o<2> to return to the unlocked position shown in Fig. 3a. The spindle a is now free for rewinding. A cam device is described for changing the drive of a motor between two such springs as occur in a striking clock. An alternative catch device functioning according to the invention is shown in Figs. 5, 6, and 7. On the running down of the spring box 12 with winding 17 locked by lever 16, a pin 13 on the box finally strikes lever 14, Fig. 7, and so through spindle 15, Fig. 6, raises lever 16, Fig. 5, out of engagement. The winding now proceeds, catch lever 16 being held disengaged through spindle 20 by a catch 21 engaging over lever 14, as shown in Fig. 7. Winding wheel 17 turns as shown by the arrow in Fig. 5 until pin 18 upon it raises lever 19, which disengages catch 21 allowing catch lever 16 to engage again and lock the winding wheel 17,

Title: Photocomposing machines
IPC: B41B27/04
Filed: 1971-04-19
Abstract: 1337767 Photographic type-composing LINOTYPE GmbH 19 April 1971 [4 April 1970] 25902/71 Heading B6W A photographic type-composing machine is controlled by a keyboard 1, Figs. 2 and 3, having a standard (as shown, German) arrangement of character keys 24 together with additional accent keys 16-18, shift keys 19 and typographical instruction keys 20-23, signals from the keyboard being passed to a control unit 2. Signals from the keys 24 pass to a binary coder 25, an input register 26 and a line register and storage 4. The registered character width valves registered are scanned so that a computer 31 can transmit to an indicator 9 information as to line remainder length. For composing an accent over a character, one of the keys 16-18 sends a signal to an accent sign register 27 in which is produced a code word characterising the accent, and which by means of a bi-stable trigger step 38 opens a gate circuit 37, the accent code passing to a matrix 39, which also receives a code formed in the register 26 on subsequent actuation of one of the keys 24, both codes then passing to the storage 4. Pressing of a shift key 19 modifies the codes in both registers 26, 27. To produce a typographical instruction, e.g. for point size, line length, film advance for line-spacing, or indentation before commencing reproduction (i.e. quad left), the register key 20-23 is first actuated, and operates one of bi-stable trigger steps 28a-28d, diverting the output of the register 26 from the storage 4 to a translator 29, decimal-to-binary converter 30 and the computer 31, and also associating the computer with the requisite one of registers 33-36. After the keys 20-23, keys 24 are actuated to give the decimal numerical value of the instruction to be given, which is stored in the requisite register 33-36. In the case of point size, a signal to the computer over a line 32 results in the necessary multiplication operation. In response to the various signals, the control unit 2 actuates the store and register 4, the computer 31, the indicator 9, a flashlight associated with a character matrix cylinder when a selected character is in the reproduction position, a mirror carriage to reproduce the character at the requisite point of the line on the film, and means for advancing the film carrier for line-spacing. The keyboard also controls a writing-device which makes a record of the composition, including a ribbon control which enables the typographical instructions to be recorded in red ink.

Abstract: 1340614 Fuel injection systems, electromagnetic fuel injectors SOC INDUSTRIELLE D'ELECTRONIQUE ET D'INFORMATIQUE 19 April 1971 [2 April 1970 2 June 1970] 26134/71 Heading F1B [ Also in Division G1] In an electrically controlled fuel injection arrangement for an IC engine signals indicative of the flow of air through an inlet 308 are derived by an ionization gauge 25 and fed to an electronic controller 300 to control an electromagnetic fuel injector 318. Signals are also derived from a speed sensor 15, a cooling fluid temperature sensor 22 and a screw 320 when a throttle 304 is in its position of maximum closure. The ionization gauge comprises a disc anode Fig.5 and a helical cathode in a duct 617 through which air flows. The difference in the currents flowing from the ends of the windings is dependent on the air velocity. The anode is supplied with pulses from a transformer 610 and the output from an amplifier 620 is fed to a pair of AND gates 622, 623 whose second inputs are fed from a further transformer winding 613. A resistor 625 in the circuit of gate 623 develops a voltage indicative of the measured signal on each input pulse, and this output is integrated in a R. C. circuit 626, 627 to provide a signal indicative of air flow. This voltage signal is converted a proportional current signal and applied to the thermistor 22. The output voltage is converted to a current at 631 and applied to an impulse duration modulator 632 which receives synchronising signals on line 54 from the speed sensor 15. A sawtooth waveform is obtained which is interrupted when its amplitude reaches the control voltage, and signals are fed to a monostable circuit 638 feeding a first winding on the injector and to a delay circuit 639 feeding a second winding on the injector. The injector may be of the kind disclosed in Specification 1340613. In a modified circuit arrangement Fig. 3 (not shown) an angle generator 380 as disclosed in Specification 1304262 is utilised.

Abstract: 1309683 Semi-conductor devices TEXAS INSTRUMENTS Inc 1 June 1970 [26 June 1969] 26221/70 Heading H1K [Also in Division H3] An F.E.T. Q2 and a bipolar transistor Q1 conduct alternately to an output terminal 12 under the control of a logic circuit such as Q3 to Q8 which receives a single input signal at 16. If the input is negative F.E.T.'s Q3 and Q7 being p-channel are on, so that Q1 is on and Q2 and Q8 are off. During this time a capacitor C charges through a load F.E.T. Q5 to nearly - Vgg. When the input goes positive, Q3 and Q7 and therefore Q1 go off, a further load F.E.T. Q6 conducts to take point N1 towards - Vgg, and the capacitor C takes Q4 gate consequently even more negative than - Vgg. Thus N1 is rapidly changed to - Vgg and Q2 and Q8 go on. When C is discharged Q6 holds N1 sufficiently negative to maintain the state of the circuit until the input changes again.  In the integrated circuit (Fig. 2, not shown) the transistors of Fig. 1 are identified, and also the capacitor C whose plates are at the gate of Q4 (46) and drain of Q3 (34). A detail (Fig. 3, not shown) shows Q1 collector as the N substrate (20), its base as a P region (24) therein, and its emitter (22) as an N+ region in the base region; the base, collector and a further P region (26) forming the drain, channel and source of Q7 respectively.
