Abstract: 1360274 Electrically controlled filling installation SPA MONOPOLE COMPAGNIE FERMIERE DES EAUX ET BAINS DE SPA 8 June 1971 [10 June 1970] 19479/71 Heading B8T A liquid filling head 1 of a bottle filling machine is connected to two electromagnetically operated shut-off valves 17, 26 whereby the liquid, after passing through valve 17, is conveyed into bottle 2 via inlet conduit 16, a chamber in body portion 4 of filling head 1 and through the space between tubes 7 and 8 of nozzle 5 until the liquid is in contact with an electrode 46 which when earthed shuts off valve 17. Shut-off valve 26 has a shunt tube 34 connected to escape conduit 25, the tube having an adjustable needle valve 35 so that on operation of a potentiometer adjusted timing relay, solenoid 32 may be energized during bottle filling and valve 26 closed, whereby gases can only pass through needle valve 35. The consequent reduction in the escape rate of gases from bottle 2, causes the rise of fluid in bottle 2 to slow down. A metal rod electrode 46, which has an insulating spacer 12, activates solenoid 22 when in contact with the liquid rising in bottle 2, thus shutting off valve 17. The electrode may be a strip or wire.

Title: Fluidised bed cooking process
IPC: A23L5/10
Filed: 1963-05-17
Abstract: 1,002,836. Treating food. INTERNATIONAL MILLING CO., Inc. May 17, 1963 [May 17, 1962], No. 19807/63. Heading A2E. In cooking foods in a fluidised bed of hot, solid, discrete particles (as is described and claimed in Specification 888,649) the foods are coated with a finely divided potato product having a reducing sugar content of less than about 0.5% preparatory to such cooking. It is stated that the coating provides a control over adherence of the solid discrete particles to the food during the cooking, in addition to providing enhanced food products. Foods mentioned: potato slices, bananas, turnips, sweet potatoes and plantain. Potato products: potato flour and instant mashed potato powder or flakes. Fluidising media: sodium chloride, sugar, tricalcium phosphate, limestone, limestone-salt mixtures and monosodium glutamate. The coating may be applied by spraying, dusting or shaking a bag containing both the food and the potato coating material. The reducing sugar content of potatoes is stated to increase, e.g. to values within the range 0.5- 2.5%, during low temperature storage due to the action of amylolytic enzymes; thus instant mashed potato products made from new potatoes have a low reducing sugar content. A commercially available tape similar to that used for determining reducing sugar content in connection with tests for diabetes may be employed as the reducing sugar indicator for specified potato-water mixtures. Examples are directed to coating potato slices with potato flour or instant mashed potato powder and then cooking the coated slices in a fluidised bed of sodium chloride at temperatures ranging from 250‹F. to 500‹F. for 2 to 4 minutes. Specification 1,002,837 also is referred to.

IPC: G03B31/04
Filed: 1954-07-08
Abstract: 823,365. Automatic speed control systems. SPECTO Ltd. Oct. 10, 1955 [July 8, 1954; Jan. 4, 1955], Nos. 20003/54 and 188/55. Drawings to Specification. Class 38 (4). A cinematograph film is synchronized with a magnetic sound record by automatically controlling relative speed from electrical means comparing the integrals of numbers of pulses recorded on the sound record and derived from the motion of the film respectively. An alternating current signal interrupted at a low frequency is recorded on a spare track of a magnetic tape sound record and the interruptions are synchronized with the motion of the film by contacts on the camera if the sound is recorded at the same time as the film, or by contacts on a projector if the sound is recorded during screening. Synchronism during reproduction is assured by comparing the number of pulses produced from the synchronizing track with the number of pulses produced by contacts operated by the projector and utilizing any difference to correct the speed of the projector motor. This correction may be effected by an electromagnetic ratchet motor-operated rheostat actuated in opposite directions by the two sets of pulses, the rheostat grid-controlling a rectifier energizing a commutator motor driving the projector. In a modification each set of pulses may operate a six-way selector, such as a multi-cathode discharge tube, controlling flip-flop valve circuits the state of which determines the volt-drop across a resistor grid-controlling the rectifier energizing the projector motor.

Abstract: 1381009 Starting I.C. engines NIPPONDENSO CO Ltd 1 May 1972 [30 April 1971] 20068/72 Heading H2H A system for starting an internal combustion engine comprises a starting motor 10 connectible to a battery 16 by an electromagnetic switch 14 which has a holding winding 13 and a winding 20 connectible to the battery via a series connected starting switch 15 and a series connected time switch 19 respectively, the time switch being arranged to interrupt, after a predetermined time beginning with the closing of the starting, switch, the supply to the winding 20. When the switch 15 is closed, current is supplied to the holding winding 13 and a shunt winding 12 which rotates the starting motor. Current also flows through a winding 21 to close a contact 25 and charge a capacitor 22. Closure of the contact 25 enables energization of the winding 20 so that a member 18 is displaced to close a switch 17 and connect the battery to the main winding 11 of the starting motor. When the capacitor 22 is charged the current in the winding 21 ceases, thus opening the contact 25 and de-energizing the winding 20. The member 18 is therefore released to break the supply to the main winding 11. The time switch may comprise a bimetallic switch, a thermal cut out or a semi-conductor switch.
