Title: Coin-freed meter for electricity, gas, water, or the like, provided with a device for making a minimum charge
IPC: G07F15/06
Filed: 1920-07-10
Abstract: 148,805. Allgemeine Elektricitõts- Ges. July 13, 1917, [Convention date]. No Patent granted (Sealing fee not paid). Electricity and gas, supplying by meter.-In a coin-freed electricity, gas, or other meter in which a preliminary charge for rent or the like must be prepaid before the apparatus can be used as an ordinary coin-freed meter, special mechanism is provided for allowing the rent charge to be varied. A spindle 4, rotatable by a knob 1, is alined with a spindle 7 carrying the usual epicyclic gear 3, and the two spindles are initially disconnected but are automatically coupled, after the preliminary charge has been paid, by the engagement ot a pin 9 on a spring disk 8 with a slot 5 in a disk 6. When the cash drawer 10 is replaced after being cleared, a lever 14 is held by a pin 15 resting on a ratchet-wheel 26 in such a position that a projection 20 on the arm 19 of the lever holds the coupling disconnected. Thereafter, each complete turn of the knob 1 (which is possible only on insertion of a coin) causes a single tooth on the disk 6 to move a mutilated wheel 23 through one tooth against the action of a spring. This wheel is connected to the ratchet-wheel 26, and is adapted to be set initially by means of a pin 31 on a wheel 30 gearing with a graduated wheel 32 that can be fixed by a screw 37. When the wheel 23 has been rotated by the tooth on the disk 6 so as to be out of gear therewith, the ratchet-wheel 26 has been sc moved as to allow the pin 15 to drop into a slot 27, thus allowing the lever 14 to turn and move tie projection 20 away from the dish 8. The spindles 4 and 7 thus become coupled together, and the meter can then be operated for supplying electricity by prepayment in the usual way. An indicating-plate 18 is exhibited by the movement of the lever 14 when payment of the preliminary charge is completed.

Title: Improvements in processes of photolithographic reproduction
Inventor: HEPHER MARTIN
IPC: G03F7/06
Filed: 1956-07-04
Abstract: 824,330. Photolithography. KODAK Ltd. July 4, 1957 [July 4 1956], No. 20660/56. Addition to 714,106. Class 98(2) The method of the parent Specification, photographic reproduction in which a silver image in an emulsion layer is used to destroy imagewise a diazonium compound through the action of a bleaching agent of the type used in silver-dye-bleach processes, the diazonium compound either being incorporated in or then diffusing into a receiving absorbent support, whereafter the diazonium compound is caused to couple with an azo coupler to form an azo dye image, is modified by selection of the diazonium compound and coupler to form an azo dye which is waterrepellent and ink-accepting and the receiving support is a lithographic printing surface. Examples are directed to coupling under the acid conditions required for the silver-dye-bleach treatment, thus a line original may be reflex printed on to a high contrast silver chlorobromide paper and the latter developed, treated in acetic acid solution, swabbed with an aqueous solution containing 1-diazoanthraquinone, cupric chloride and hydrochloric acid, and then pressed on to a casein coated paper sheet which has previously been treated with an aqueous ethanolic solution of #- naphthol as by passage through a household wringer and the negative is stripped away revealing a positive red dye image on the coated paper sheet, which latter is placed on an offset machine, damped, and then used for printing in the ordinary way. The diazo bleach solution may be replaced by one containing 2(4<SP>1</SP> methyl-2'- nitro phenylazo)-4 : 6 dimethyl benzene-1- diazonium chloride instead of 1-diazoanthraquinone to give a similar but blue image. A solution containing 1-diazo-2- nitro-4-methyl benzene and hydrochloric acid which bleaches without inclusion of cupric chloride may be used. A manner of operating the invention following the "two component" diazotype procedure with alkaline development is indicated. Anodizedaluminium, surface oxidized zinc, and surface hydrolysed cellulose ester sheeting are referred to as further lithographic printing surfaces.

Abstract: 901,525. Feeding webs. RADYNE Ltd. June 3, 1960 [June 17, 1959], No. 20819/59. Class 100 (1). [Also in Group VIII] Two strips 1 of plastic material to be welded together on a bed 3 by an electrode 14 are fed intermittently by spring-clamping fingers 8, carried by a spindle 7 having a manuallyoperable lever 6. The spindle is mounted between plates 9 mounted on bearings 10 slidable along rails 11 between adjustable stops 12 and 13. In operation, clockwise rocking of lever 6 causes the fingers 8 to first engage the strips 1 and then feed them in the direction of the arrow until the bearings 10 contact the stop 12. The welding operation is then performed and the lever 6 rocked counterclockwise to release the strips. The strips are retained during the return stroke of the fingers 8 by similar fingers 17 actuated by a manuallyoperable lever 18. A plate 4 supports the strips during gripping engagement with the fingers 8 and lifts the strips 1 from the bed after welding. The fingers 8 may be replaced by magneticallyoperating clamps.

Title: Improvements in or relating to inverters
Inventor: KULZER HEINRICH

Filed: 1963-05-25
Abstract: 998,031. Inverters. SIEMENS & HALSKE A.G. May 25, 1963, No. 20988/63. Heading H3T. An inverter for converting D.C. to A.C. comprises two capacitors C1, C2 connected in series across the input terminals and two transistors Ts1 Ts2 also connected in series across the input terminals, a transformer UT having a primary winding W1 connected between the junction of the transistors and the junction of the capacitors, second and third windings W2, W3, respectively, on the transformer, each connected to the control electrode of one of the transistors so that they are rendered alternately conductive when the circuit is in operation, and a secondary winding W4 connected to the A.C. output terminals. In order to render the arrangement self-starting bias means in the form of resistor R3 are connected to the control electrode of one transistor so that this transistor is rendered conductive when the D.C. supply is switched on. According to the invention, in order to prevent the arrangement being put out of operation by a temporary short-circuit of the output side, which would cause capacitor C2 to charge up to the full D.C. potential so that transistor Ts2 would become permanently blocked, a voltage regulating device, e.g. a Zener diode D in series with resistor R4 is connected across the capacitor C2, being such that the breakdown voltage is slightly more than half the D.C. supply potential. Resistors may be connected in series in the leads to the control electrodes of the transistors, giving some control over the frequency of oscillation.

Relates to apparatus for use on aircraft for determining the speed of the wind &c. by means of a sighting device which is maintained directed towards an object-on the ground and is operatively connected to a tracing recording-device. The required data are obtained from the record by means of a calculating device which is mounted over it. This device comprises a bar 100 slidably mounted on the base 11 bearing the record and adapted to be held by a clamp 101; adjacent this bar is a bar 102 the graduations on which represent angles. The bar 100 carries a disc 103 bearing compass graduations and adapted to be held by a clamp 104 which carries a pointer to co-operate with the bar 102 and an arrow indicating the fore-and-aft line. Pivoted at the centre of the disc 103 is a graduated " speed " arm 105 on which is slidably and rotatably mounted a slotted graduated rule 106. The arm 105 is set in the fore-and-aft direction and the rule 106 is set along the arm 105 to a position corresponding to the linear speed of the aircraft, this being obtained from a chart when the total angle of movement of the line of sight, the time of observation, and the altitude of flight are known. The bar 100 is moved until the indicator 104 is opposite the point on the scale 102 corresponding to the angle between the initial line of sight and the vertical. The rule 106 is then turned until the slot is over the terminal point of the record. A line drawn along the slot then indicates the direction of the wind and its length between the record and the arm 105 represents to scale the wind velocity.
