Title: Improvements in coin operated hot food dispensing and vending machines
IPC: G07F9/10
Filed: 1961-01-16
Abstract: 945,891. Coin-freed vending apparatus. A. REID, and A. E. FOSTER. Dec. 27, 1961 [Jan. 16, 1961], No. 1659/61. Heading G4V. A machine for vending pre-cooked frozen foods in foil packages has two refrigerated storage compartments between which is an infra-red grill and, on insertion of a coin in one of the two coin slots corresponding to the two compartments, a motor drives a cam-shaft which controls the delivery of a package into the grill and then, after it has been heated for the required time, into a delivery shoot. A coin inserted past a pair of spring-loaded plates c<SP>1</SP>, Fig. 6, in the coin slot falls down a shoot d<SP>1</SP> and tilts a lever f<SP>1</SP> so that a mercury switch is tripped and the cam-shaft motor is switched on. A cam surface h<SP>1</SP> on the lever shifts a spring- loaded rod so that it enters a hole g<SP>1</SP> in the lever f<SP>1</SP> of the other coin slot and prevents operation of the other half of the machine and a catch lever t<SP>1</SP> holds the lever f<SP>1</SP> in operative position after the coin has fallen to a cash box. The cam-shaft has a pair of spaced cams f<SP>2</SP>, g<SP>2</SP>, Fig. 9, engaging a pair of switches i<SP>21</SP> and the cam f<SP>2</SP> causes its switch i<SP>21 </SP>to activate a solenoid k<SP>3</SP>, Fig. 11, and the solenoid armature i<SP>3</SP> moves a pusher plate n<SP>3</SP> along a slotted plate m<SP>3</SP> at the foot of the storage compartments and delivers the lowermost package into the grill. The next uppermost package, in falling, tilts the pusher n<SP>3</SP> about its pivot b<SP>3</SP> against the action of a spring d<SP>3</SP> and the pusher returns to its initial position along the underside of the slotted plate. The other cam g<SP>2</SP> then closes the other switch i<SP>2</SP> to activate the grill and holds it closed for a time sufficient to heat the contents of the package. The first cam f<SP>2</SP> finally operates its switch i<SP>2</SP> again and a solenoid is energized to swing a hinged arm through the grill and deliver the heated package to a delivery shoot. The cam f<SP>2</SP> also operates a trip wire u<SP>1</SP>, Fig. 6, to release the catch t<SP>1</SP> and allow the switch, lever f<SP>1</SP> to return to initial position. Each solenoid is connected to a pneumatic dashpot having an adjustable needle valve.

Title: Photographic lens
IPC: G10B1/08
Filed: 1925-01-20
Abstract: 234,743. Ernemann-Werke Akt.-Ges. Oct. 24, 1924, [Convention date]. Lenses. - The constructional length of the lens described in Specification 193,376 is shortened by reducing the length of the third air space. The errors of chromatic correction introduced by this shortening are corrected by increasing the power of the cemented negative lens, whereby the parallel rays incident on the first surface of the first lens are divergent upon emerging from the dispersive lens. The increase in the zonal spherical aberration consequent upon the increase in the power of the negative lens is eliminated by arranging the refractive index of the positive lens to be greater than that of the negative lens. Numerical data are given in the Specification.

Abstract: 609,025. Lenticular-screen colour photography. LASSUS ST. GENIES, A. H. J. DE, and COMPAGNIE FRANCAISE POUR L'EXPLOITATION DES PROCEDES THOMSONHOUSTON. Jan. 29, 1940, Nos. 1746 and 1747. Convention dates, Jan. 27, 1939, and June 23, 1939. [Class 98 (ii)] A device for dividing and redistributing the light entering the objective of a camera for making a colour photographic record on lenticular film, a conventional three-band colour filter being disposed immediately in front of the lens, consists of means for initially dividing in half the light-beam which would otherwise be incident on each band of the filter, the division being effected either lengthwise or transversely of the band, and of a system of totally reflecting or partially reflecting and partially transmitting mirrors so positioned that they redistribute the resulting six beams in such a manner that each incident beam covering only one half of a filter band is either deflected so as to traverse another half band or simultaneously partially deflected and partially divided so as to traverse two or three half bands, the total incident flux being uniformly reassembled on the filter after emergence from the system and the emergent beams remaining parallel, after two reflections, to the incident beams, whereby registration is obtained between the component images of each exposure recorded on the film when the objective is focused to infinity. As shown in Fig. 1, the mirrors M1, M<1>1, M2, M<1>2, M5, M6, M7 and M<1>7 are totally reflecting and the mirrors M3 and M4 are partially reflecting and partially transmitting. The filter bands are shown at b, v and r. The device may consist of two glass plates I and II in which the reflecting surfaces are inserted. Part of the mirrors M3 and M4 may be' totally reflecting. The mirror M<1>2 may be partially transmitting and a partially-transmitting mirror provided to pair with M6. The three-band filter, Fig. 4, may be modified by omitting the corners N and by providing masks K. Some of the mirrors may be rotatable and coupled with the focusing movement of the objective to enable the device to be used at other focusing distances than infinity, or the device may be made of flexible transparent material.

Title: Walking and sitting doll
IPC: A63H7/00
Filed: 1953-01-22
Abstract: 724,659. Walking dolls. GERBAUD, H. Jan. 22, 1953, No. 1876/53. Class 132 (3). A doll, which will walk when led and can sit down and has a yoke member that pivots in response to the swinging of one leg to swing the other leg in the opposite direction, has the yoke member frictionally coupled to each leg so that, if there is resistance to the movement of the second leg, the coupling between the leg and the yoke member will slip. A mounting member 20, disposed within the torso which is formed by two parts 21, 22, has a hole 25 through which a shaft 26 extends and a slot 27 in which a channel led cross-piece 29 is pivoted. The inner end of each leg has a rim 60 fitting into a cap 39 and having a cut-out 61 and lugs 62 to register with a slot 41 and grooves 42 in the cap. If the cap is of plastic it may be faced with a metal disc 43. Each leg carries a clamp 45, e.g. of folded sheet metal, gripping a pin 46 which extends through a slot 47 in cross piece 29. Pins 46 may have eyes mounted loosely on shaft 26 between the jaws of clamps 45 which have bosses 50 and channels 51 to accommodate the eyes and pins 46 and notches 53 to engage lugs 40 on the cap. Springs 54 held on hollow rivets 44 passing through holes in clamp 45 and cap 39 secure the assembled parts of each leg. Conical compression springs 58 press against clamps 45 and have their outer ends anchored in notches 59 in shaft 26 to secure the legs in the mounting. If shaft 26 is fixed to member 20, caps 39 and clamps 45 should turn freely thereon but if shaft 26 turns in member 20 then at least one cap and its associated clamp should be free for turning thereon. To limit the movement of the arms of the doll at least one of the arms carries a pin 64 on its socket which engages a stop pin 65 secured inside the torso. Thus the doll can be led along by its arm and when one leg moves backwards and its associated pin 46 moves forwards, cross piece 29 will be rotated so as to push the other pin 46 backwards and hence the other leg forwards. Thus, as the doll rocks from one leg to the other, the legs will be given a walking motion. If the legs are held parallel and forced forwards the pins 46 will move in clamps 45 until they engage a different set of grooves thus allowing the doll to be placed in a sitting position.

Title: Process for preparing synthetic pyrolusite
IPC: C01G45/02
Filed: 1961-01-19
Abstract: Synthetic pyrolusite suitable for use as a depolarizer is prepared by rapidly and intensely mixing a manganese (II) and/or a manganese (III) salt solution with a 1 to 30% stoichiometric excess of a hypochlorite solution during a period of less than 20 minutes per cu.m. of final volume of the mixture, the mixture being so alkaline or rendered alkaline by the addition of a hydrooxide and/or a carbonate of an alkali metal and/or an alkaline earth metal that after precipitation of the pyrolusite the remaining solution has a pH within the range of 2 to 7.  The manganese salt solution is advantageously obtained by the dissolution of natural pyrolusites or their reduction products in hydrochloric acid and preferably contains 5 to 25% by weight of manganese and 0,5 to 5% by weight of free hydrochloric acid, although other manganese salt solutions can be used, for example manganese (II) sulphate solutions.  The process may be carried out batchwise or continuously.  In batch operation the hypochlorite and alkali metal and/or the alkaline earth metal component are preferably added to the manganese salt solution although the reactants may be mixed in the reverse order.  During the mixing of the reactants the reaction medium may be cooled directly or indirectly.  After termination of the reaction it is advantageous to wait at least five minutes before isolating the precipitate so that any manganese hydroxides are oxidized to a large extent to the tetravalent state by the action of dissolved chlorine or chlorine entrained in the precipitate.  The activity of the pyrolusite may be increased by washing with water for more than one hour.

Title: Improvements in circular looms for weaving
IPC: D03D37/00
Filed: 1933-01-24
Abstract: 414,046. Circular looms. BRITISH CELANESE, Ltd., and JABOULEY, J., 22, Hanover Square, London. Jan. 24, 1933, No. 2268. [Class 142 (ii).] Relative movement between the shuttles and the warps of a circular loom is brought to an end by clutch means connected to one part but norinally out of engagement with another part and feeler controlled coupling means adapted to connect the clutch means positively to the second part so that further relative rotation brings about firm engagement between the parts. The invention is described in connection with a loom of the type set out in Specification 396,757, a brake band 7, connected at one end to a stationary shuttle supporting ring 5, being provided to encircle a toothed ring 6 rotating with the warps. The brake band 7 is normally held clear of the ring 6, against the action of a spring 22 connecting the band to an abutment 12, by a pivoted latch 19 which is mounted on a pivoted lever 18 connected to the free end 17 of the band. On breakage or jamming of the warps the rotation of a ring 29, by the action of the feeler mechanism on the shuttle 30, rocks a shaft 26 and releases the latch 19, whereupon the band 7 is moved into engagement with the ring 6 by the spring 22. The initial movement of the brake band causes a pin 14 thereon to tilt a pawl 9 on the lever 12 into engagement with a tooth on the ring 6, continued rotation of the .latter drawing the brake band 7 into firm engagement with its periphery and imparting a rotary movement to the ring 5. The pawl 9 comprises two yieldingly connected parts which give slightly in the event of the pawl striking the top of a tooth. Specifications 285,435, [Class 142 (ii)], and 413,376 also are referred to.
