Title: Miniature toy vehicle
IPC: A63H18/08
Filed: 1969-07-07
Abstract: 1,255,387. Toy vehicle. IDEAL TOY CORP. 7 July, 1969 [27 Dec., 1968], No. 34149/69. Heading A6S.  A wheeled toy vehicle driven by a batteryoperated motor has an energisation circuit comprising a pair of normally closed contacts 39e, 57d and means mounted on the chassis body adjacent the contacts having a portion 71 thereof depending from the undersurface of the chassis body, the mounted means normally allowing the contacts to be closed but being operative when the depending portion is moved out of its normal position (thereby to open the contacts and halt the vehicle) by e.g. part 83a of moveable lever 81. The invention may be applied to a vehicle such as described in Specification 1,005,849 but which is modified by the addition of a steering pin at the front of the vehicle which may fit into a slotted track or is retractable if the track is not slotted.

Patent GB-1366009-A (GB)
Title: Reading apparatus
IPC: G06V10/98
Filed: 1972-07-21
Abstract: 1366009 Character recognition systems DE STAAT DER NEDERLANDEN TE DEZEN VERTEGEN-WOORDIGD DOOR DE DIRECTEUR - GENERAAL DER POSTERISEN TELEGRAFIE EN TELEFONIE 21 July 1972 [22 July 1971] 34149/72 Heading G4R A character recognition system attempts to identify a scanned character and, if the identification is uncertain, the identity of one or more most likely characters is compared with a signal provided when an operator presses that key which corresponds to his visual identification of the character. If one of the most likely characters is the same as that chosen by the operator, that character is assumed to be the required identity of the uncertain character. The characters are handwritten. The scanner output passes to a feature extractor, not described, which feeds a first recognition circuit. The circuit includes groups of comparators, one group for each possible character, the sums of the outputs of each group being determined. That group giving the largest sum identifies the character and provides a corresponding signal to, for example, a punching machine. A second recognition circuit is provided, this having less rigorous recognition criteria than the first so that, although the first circuit may be unable to identify the character, the second will provide one or more signals representing the nearest of the possible identifications. The unidentified scanned character is now displayed on a monitor and an operator attempts to identify it visually. He presses a corresponding key on a keyboard to provide a signal which is compared with the nearest identity signals from the second reognition circuit. If equality is found the keyboard signal passes to the punch. If there is no equality a reject signal is given. Various of the signals are accompanied by coding which indicates the position of the scanned character in a multi-character store fed by the scanner. This ensures that the required character is displayed to the operator and that the character identified by him is punched in the correct position. Because the operator will be required to identify only a small proportion of the characters scanned by a single scanner, the unidentified characters from several scanners may be multiplexed on to the display. The various signals must then be accompanied by additional coding indicative of the scanner so that the characters identified by him are presented to the correct punch.

Patent GB-932347-A (GB)
Title: Flavoring of baked comestibles
IPC: A23L27/20
Filed: 1961-09-26
Abstract: Losses of flavour in flavouring material incorporated in a comestible prior to baking and which are due to volatilization of volatilizable components of the flavouring material during the baking step, are avoided by baking the comestible in the absence of at least the volatilizable components of the flavouring material, and subsequently applying the volatilizable components to the baked comestible in the form of a liquid which is readily adsorbed by the baked comestible; they may be sprayed on to the baked comestible in a liquid diluent carrier such as water, edible organic solvents e.g. alcohol, coconut oil, soy bean oil, cottonseed oil, or melted hydrogenated shortening. Comestibles mentioned are cheese crackers, biscuits, cookies, pastry, leavened bread, rolls and baked animal foods.  Flavourings mentioned are cheese, butter oil, vanilla, lemon oil, orange oil, celery seed oil, onion oil and caraway seed oil.  In a preferred procedure for flavouring cheese crackers the volatile components of a cheese product (specified) are extracted with one of the above diluents to produce a solid residue of non-volatile non-extractable materials and a liquid extract of volatile components, the solid residue is mixed with cracker dough, the combined dough is baked and the liquid extract is then added to the baked dough. According to an Example (1) cheddar cheese, 494 parts, was finely ground in a comminuter together with 2 parts lecithin, 8 parts salt and 2 parts ammonium bicarbonate, and the comminuted mixture was placed in a steam-jacketed kettle with a small quantity of coconut oil; after five minutes of mixing, additional coconut oil was added to make up 494 parts of the oil, the mixing being continued for an additional 20 minutes at a temperature of 130-155 DEG  F.  The solid cheese residue and the liquid oil mixture were mechanically separated on a vibrating screen; the cheese residue was incorporated in a cracker dough which was then baked, while the oil mixture was sprayed on to the hot crackers after they had emerged from the oven, the unused oil being recovered, filtered and used over again.  The proportion of cheese in the crackers amounted to between 6 and 20 parts per 100 parts by weight of the cracker.  According to another Example (3) a flavoured oil mixture consisting of 5 parts lemon oil and 95 parts coconut oil was sprayed on to a baked cookie product as it emerged from the oven, to produce a lemon snap cookie.  In a further example, whole dog food biscuits, dog food meal, pelleted, kibbled and extruded dog foods were enhanced by spraying them immediately after baking with a mixture consisting of one part of the cheddar cheese-oil mixture from Example 1 above, after separation, and 99 parts of melted animal fat or a vegetable oil such as cottonseed or soy bean oil.

Filed: 1927-12-28
Abstract: 283,135. Telefonaktiebolaget L. M. Ericsson, (Assignees of Laurent, T.). Jan. 4, 1927, [Convention date]. Manual exchange systems. - In systems in which currents of a broad range of frequencies such as voice frequencies and other signals of a narrow range within the broad range such as calling and clearing signals are transmitted over the same long-distance line, the receiving arrangements comprise a blocking device responsive to frequencies other than the signal frequencies to prevent incorrect operation of the signalling means by speech currents. In one arrangement, Fig. 1, the anode circuit of an amplifier 10 associated with the incoming end 11, 12 of the line contains filter circuits 15, 16, the former being non-permeable to signal currents so that these pass through transformer 6 to operate a relay 2, whilst the circuit 16 passes only signal currents so that all other frequencies pass to transformer 7 and operate relay 3. Signal currents thus operate signalling device 1 whilst other voice frequencies hold open the signalling circuit. The construction of filters 15, 16 is such that if voice currents of signal frequency arrive at the commencement of operations, relay 3 will act more quickly than relay 2 to prevent its falling back in response to momentary speech-currents of signal frequency. In another arrangement, Fig. 2, the signal 1 is controlled by a single relay 19 in the anode circuit of a valve 20 to the grid of which are connected neon tubes 25, 26. Signal currents passing through transformer 6 render tube 25 conducting and increase the positive potential on the grid, thus operating relay 19. On the other hand, voice currents render tube 26 conducting and make the grid more negative. In a modification, the secondary of transformer 6 is directly connected to the grid of valve 20, but a neon tube is connected directly between grid and filament, The invention is stated to be applicable also to wireless telephone systems, to systems in which a carrier current of voice frequency is employed and to telegraph systems.

Title: Improvements in optical sights
IPC: G01J1/42
Filed: 1960-10-13
Abstract: 911,990. Optical sights; optical adjusting apparatus. CIBIE, P. Oct. 13, 1960 [Oct. 30, 1959], No. 35141/60. Class 97 (1). An optical sight consists of several thin parallel opaque blades separated from one another by transparent gaps and arranged in a common support. As shown in Fig. 3, the opaque blades 5 are separated by gaps 6 and mounted in a support 7, one side 7a of which is fixed to a part 8, which is rotatable in a bush 9 on a supporting arm 10 so that it may occupy positions defined by a pin 11 slipped through holes in the part 8. The blades 6 may be of metal, glass or a synthetic substance and are preferably blackened to avoid parasitic reflections. The width of each gap and the length of each blade are preferably so chosen that the angle formed with the planes of the blades by the straight line joining two points which are sighted through one of the transparent gaps is equal to or less than the designed tolerance on the degree of parallelism between the planes of these blades and said straight line so that the straight line can be regarded as being parallel to the reference plane defined by one of the blades. The sight may be used for positioning an apparatus for adjusting vehicle head lamps. Thus, as shown in Fig. 6, the sight 12 is mounted by its arm 10 on a support 14 movable about a point 15 on an optical unit 13 which is carried by a stand 16 on a carriage 17. The axis of the optical unit is set parallel to the plane of the ground by using aiming sights (such as 18) placed on the ground near to the front and rear wheels of a vehicle 22. The sight is arranged with its blades perpendicular to the axis of the optical unit 13 and a mirror 23 reflects the image of the sights towards the sight 12. The complete assembly consisting of the optical unit and the optical sight is then displaced until the line of sight 4b is parallel to the sight blades. The axis of the optical unit is then positioned so that it is parallel to the line of travel of the vehicle. For this purpose the optical sight 12 is placed with its blades perpendicular to the axis of the optical unit 13 and aiming sights 25, Fig. 8, are placed on the head lamps 24 and the optical unit and the sight are displaced until the line of sight 4c passes through the tops of the two aiming sights. The aiming sights 25, as shown in Fig. 11, may each comprise a suction cap 28 for fixing the aiming sight to the head lamp, each suction cap being rigidly attached to a T-shaped supporting spheres 31, 32 of different diameters and contrasting colours.

Title: Improvements in or relating to a method of and means for supplying fuel to internal combustion engines
IPC: F02M59/10
Filed: 1934-12-07
Abstract: 437,853. Oil engines. L'ORANGE, P., 130, Cannstatterstrasse, Feuerbach, Stuttgart, Germany. Dec. 7, 1934, No. 35167. Convention date, Dec. 7, 1933. [Class 7 (iii)] In an engine having a combustion chamber 2 separated from the cylinder 1 by a narrow passage 3, fuel is introduced during the suction or scavenging stroke of the piston into a small receptacle 6 and a portion is blown, by the increase in pressure in the cylinder during the compression stroke, into the chamber 2, where it mixes with air and is ignited. The increase in pressure in the combustion chamber blows the remainder of the fuel in the receptacle 6 into the cylinder. The fuel is supplied, in a twostroke engine by the pressure of the scavenging- air or exhaust gases in the cylinder or in a fourstroke engine by atmospheric pressure, to an inlet 22 and enters the receptacle past a valve 8, which is controlled by hand, by a governor, or by the pressure in the air-inlet pipe, and a non-return valve 9. The receptacle may be formed by one or more long narrow holes or by a hole of large bore provided with a filling-piece having a smooth or grooved wall carried by a screw 19. The injection orifice 5 leading into the cylinder is larger than the orifice 4 leading into the combustion chamber, which is preferably spherical and closed by a cover 15 made of refractory or catalytic material and heated at starting by an incandescent spiral 18. To increase the pressure difference between the cylinder and the combustion chamber towards the end of the stroke, the passage 3 may be throttled by an extension on the piston. Ignition may be promoted by traces of fuel entering the cylinder during the suction stroke and becoming ignited. The passage 3 may be formed by two conical frusta or by wide cylindrical outer parts connected by a narrow cylindrical middle part, or may be uniformly cylindrical.
