Title: Improvements in and relating to cash registers
IPC: G06C7/10
Filed: 1925-03-03
Abstract: 237,830. National Cash Register Co., Ltd., (National Cash Register Co.). March 3, 1925. Cash registers with operating-means; printing totals.-The items are set by lever keys but the operations of item-entering and of total-taking are performed by an independent source of power, the drive from which proceeds either to the item-entering or the total-taking mechanisms dependent upon which of two control keys, namely an "item" or a "total" key is used. The machine as regards its general construction is of the key-set and operated type with independent driving means for taking totals by means of the feelers 96 as described in Specifications 141,012 and 142,436, but in all item-entering operations the coupler 31 is rocked by a motor releasable by the " item " key 21. Each amount key 20 consists of two parts 23, 24, Fig. 2, pivoted on a common shaft. The front part carries a bell-crank lever 26 anchored by a spring 25 and having a pin 27 overlying one arm of the rear part 24. Thus depression of an amount key causes the part 24 to rise and in the subsequent rocking of the coupler 31 to move with it and through the differential upright 34 to actuate the totalizer and set the item type wheels. The key is locked down temporarily by a rocking member 170<A> co-operating with a nose 171. When the item has been completely set up the " item " key 21 is depressed to rock a shaft 180 clockwise, Fig. 6, and, through a slidable catch plate 192, free a hook 188 from a fixed pin 189 and thereby allow the spring-controlled link 187 to move to the right and release the motor. Meanwhile, the rocking of shaft 180 causes through a pin 206 a catch lever 233 to obstruct a pin 211 and thereby prevent depression of the total key 22 and at the same time an arm 231, Fig. 2, is rocked over and under projections 240 on depressed and undepressed amount keys respectively, to prevent interference with the keyboard. The motor drives the coupler by means of gear wheels 152, 153, Fig. 1<B>, and a shaft 154 provided with a slidable sleeve 170 adapted to clutch the shaft with either a loose cam 160 or a loose gear wheel 166. Normally the cam is clutched and through a lever 162 and link 166 produces the rise and fall of the coupler. When a total is to be taken, however, the total key 22 is depressed to release the motor, by means of a pin 209, Fig. 6, and at the same time through a link 216 to rock a yoke 218 cam-grooved to engage a fixed pin 222. This causes an axial displacement of the yoke and consequently of the clutch sleeve 170 so that the drive will now pass from shaft 154 to gear wheel 166 instead of to cam 160, and will thus operate the main shaft 108 of the total-taking mechanism.

Title: Improvements in or relating to optical systems
IPC: G03B21/20
Filed: 1938-02-24
Abstract: 493,681. Optical-projection systems; projector lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Feb. 24, 1938, No. 5879. Convention date, Feb. 27, 1937. [Class 97 (i)] [Also in Group XI] In an optical system comprising a source of light and a condenser, refracting surfaces are arranged in the neghbourhood of the light source so that light radiated over a given solid angle, exceeding 120‹, by the portion of the light source in or near the axis of the system, is directed on to the condenser within a smaller solid angle. The system is particularly intended for use in a kinematograph projector to enable a super-pressure mercury-vapour discharge tube to be used as the source of light. In the form shown, the condenser is a mirror 2 and the refracting surfaces comprise an annular lens 6 having a conical cavity in which the source 1 is placed. This cavity preferably communicates with another conical cavity as shown so that the lens has an axial bore. With this system, all the rays emitted over an angle c are received by the condenser, the lens forming a virtual image of the light source at the axial point 11. When a super-pressure mercury-vapour tube is used as the light source, the glass vessel, indicated in dotted lines in the Figure, which surrounds the source and acts as a receptacle for cooling liquid, is so shaped as to co-operate with the lens 6 to produce the desired effect on the light rays. Preferably, the refracting surfaces are such, and so disposed, that substantially no light falls on the axial area 12 of the mirror ; this part of the mirror can then be removed to form an aperture through which the light source and lens 6 can be passed.

Title: Improvements in and relating to discharge devices for shaft furnaces and the like
IPC: F23J1/00
Filed: 1923-02-28
Abstract: 195,054. B³hler, Geb. March 20, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Pneumatic conveyers.-A device for discharg. ing materials from shaft furnaces and other containers and apparatus worked with internal pressure, such for example, as pneumatic conveyers, comprises a jigging shoot 1 with a pair of discharge doors 7, 8 which are operated alternately. The shoot is reciprocated by an eccentric 6, and at its upper part it slides in contact with the fixed furnace outlet 28, a tight joint being maintained by packing-rings 32, 33, Fig. 3. Between these rings is a groove 38, to which air under pressure is supplied by a pipe 39, so that escape of dust-laden air is prevented should the packing leak. The door 8 is mounted on a shaft 10, and is actuated at intervals by a cam 14 on a shaft driven by the pawl and ratchet 12, 13. On the same shaft as the cam 14 is a second cam 20, which actuates the door 7 through the levers 19, 17 and the link 18. The cams are so positioned that both doors are not open at once, and to effect a more positive closing, lever arms on the two doors are connected by a spring 23. Interconnected with the doors are pivoted flaps 24, which stand vertically when the doors are closed and turn downwards as they open, thus preventing any discharge of material during the early stages of the opening movement and the later stages of closing, and also preventing material from jamming between the door and its seat.

Filed: 1927-03-03
Abstract: 293,077. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 3, 1927. Retorts.-Apparatus for carrying out processes such as the heat treatment of coal, particularly at high temperatures and pressures with gases, liquids, &c., containing hydrogen, oxygen, 'or sulphur is made of iron particularly free from impurities. The degree of purity must be such that the iron shows under the microscope no corrosion at the boundaries of the grains after treatment at a high temperature with gases or liquids containing oxygen or sulphur and preferably in presence of hydrogen. The requisite degree of purity may be obtained by subjecting iron, at high temperatures and under conditions precluding oxidation, to the action of gases which form gaseous compounds with the impurities (oxygen, sulphur, carbon &c.). For example mild steel may be treated with hydrogen at 900' C., or with a weakly oxidizing mixture of hydrogen-water vapour at 550-600‹ C. and 150 atmospheres. The apparatus may be further protected with a coating of resistant material such as chromium tungsten, uranium, manganese, aluminium, silver, copper, enamel &c. Specification 275,662 [Class 32, Distilling &c.] is referred to.

Abstract: 1,132,806. Rotor unbalance measuring systems. W. & T. AVERY Ltd, Feb. 9, 1967 [March 5,1966], No.6215/67. Heading G1N. [Also in Division H3] The signal from a rotor unbalance measuring device is fed to a stroboscope and meter via a filter whose frequency characteristic is automatically adjusted to agree with the speed of rotation of the test rotor. As shown (Fig. 1), a rotor 2 is rotated in an unbalance measuring machine 1, producing an unbalance signal in pick-off 3 which is fed through an amplifier 4 in parallel with a band stop filter 5 to a meter 16 and stroboscopic lamp device 15. The filter 5 is a tuned T-network (Fig. 3) comprising capacitors 32, 34 and resistors 31, 33 constituted by magneto-resistive semiconductors. The rotor speed is sensed by device 6, 7 producing a D. C. voltage signalwhich is indicated at 9 and fed to a mixer 10, comprising two transformers magnetically coupled to the semiconductors 31, 33 of the filter. When the speed signal exceeds a bias preset by potentiometer 42, the flux produced in the cores of the transformers modifies the resistances 31, 33 and the frequency characteristic of filter 5 accordingly. Thus the lower frequency limit of the signals passed by the 4, 5 combination is preset by potentiometer 42, and the upper limit by potentiometer 45. In a modification, an automatic sensitivity control is introduced after the unbalance transducer 3, which utilizes the speed signal to stabilize the sensitivity of the unbalance signal against variations due to speed changes.
