Title: Improvements relating to toasting appliances
Inventor: SANDERSON GEORGE
IPC: A47J37/08
Filed: 1949-06-22
Abstract: 675,303. Retractive switches. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 22, 1950. [June 22, 1949] No. 16530/49. Class 38 (v). [Also in Group VI] A toasting appliance comprising timing mechanism for switching off the supply of current after a predetermined time, has a switch with its movable contacts mounted on and biassed away from the other contacts by a resilient device which is movable under control of an intermediate cranked portion of a rod that is rotatable at the initiation and termination of the toasting period. As shown, a toaster has vertically arranged heating elements defining two toasting chambers containing bread carriers 12 which have rearwardly extending portions 13 connected to a bracket 14 mounted for vertical movement on a guide rod 15. A bell crank 18 having one arm pivotally connected to bracket 14, has its other arm connected to a spring 20 which tends to hold the bread carriers 12 at their upper positions, and has another arm 35 which is coupled to an arm 34 that is connected to a centrally cranked rod 32 pivotally mounted in lugs 33. Adjacent the cranked portion of the rod 32 are two spring strips 21, connected by an insulating member 22, having upper arcuate ends connected through metal bars to the upper terminals 24 of the heater elements, while the lower ends of the strips carry contacts 25 which are moved against fixed contacts 26 connected to plug pins 27, when the bread carriers are depressed to their lowest position. The bracket 14 is depressed by a bracket 36 slidably mounted on guide rod 15 and connected by a strip 5 to an operating knob 6. When bracket 14 is depressed to its lowest position, a stud 37 thereon is engaged by the lower end of a strip lever 38 pivoted on the casing of a clockwork timing mechanism 40 comprising a rack 41 which, when moved downwardly by a forked portion 42 on bracket 36 engaging a stud 43 on rack 41, causes the timing mechanism to be wound. As the rack moves upwardly, it carries with it the bracket 36 which, by means of an inclined surface 44, operates a stud 45 to disengage the trip lever 38 and thereby release the bracket 14 which, with the bread carriers 12, rises under the influence of spring 20 and permits opening of switch contacts 25, 26 to de-energize the heating elements. The speed of the timing mechanism and hence the degree of toasting may be adjusted by a manually rotatable knob 46 which rotates a cam 47 to engage a speed control lever 48 on the timing mechanism. A bimetal strip 49 carries a metal strip 50 which engages a further control lever on the timing mechanism to compensate for the residual heat when using the appliance for second and subsequent toasting operations. U.S.A. Specification 1,866,808 is referred to.

Title: Vehicle safety arrangement
IPC: G01S13/931
Filed: 1971-05-24
Abstract: 1346685 Radar TOYOTA JIDOSHA KOGYO KK 24 May 1971 [27 Dec 1970] 16740/71 Heading H4D A system for detecting potential collisions between a vehicle M, Fig. 1A, and an object m comprises transmitting means A 1  and receiving means A 2  mounted on the vehicle and having respective radiation patterns which intersect at an angle. In this way, a detection region or sensitivity zone A v  is defined and if the object in enters therein it reflects some of the radiation from the transmitting means A 1  into the receiving means A 2 . A detecting means which is responsive to the transmitting means signals, and to the receiving means signals when of a different frequency, produces an indication when said frequency difference exceeds a predetermined value. A transmitting means and a receiving means may be provided on each side of the vehicle, so that a sensitivity zone may be defined which is centered on the axis of the vehicle (Figs. 1B, 1C, not shown). The ratio of frequency differences due to the Doppler effect detected in respect of each side of the vehicle is unity if the object m is on the axis of the vehicle M. If said ratio is outside a predetermined range (within which the object and the vehicle will just contact each other) it may be arranged for the production of the aforesaid indication to be inhibited. As described, a microwave generator 1, Fig. 4, feeds right- and left-hand transmitting horn aerials 2R, 2L through directional couplers 4R, 4L. Reflected waves are received by right- and left-hand horn aerials 3R, 3L and the received signals are coupled, together with some power from the generator 1, into detectors 5R, 5L. Signals at the Doppler frequencies from said detectors are coupled through amplifiers 6R, 6L to respective frequency/voltage converters 7R, 7L and threshold circuits 9R, 9L. The outputs from the converters 7R, 7L are taken through threshold circuits 8R, 8L to the inputs of an OR gate 11, and the outputs from the threshold circuits 9R, 9L are taken to the inputs of an OR gate 10. An output is obtained from the gate 11 if either Doppler frequency exceeds a pre-determined value, and an output is obtained from the gate 10 if the amplitude of either signal of Doppler frequency exceeds a pre-determined value. The outputs of the said gates are taken to two of the three inputs of an AND gate 14. The outputs of the two frequency/voltage converters are also taken to separate inputs of a divider 12, and a ratio-dependent output signal therefrom is taken to a comparator 13, which gives an output if said ratio lies within a pre-determined range. The output from the comparator 13 is taken to the third input of the AND gate 14. A valve 18 is opened by an amplified signal from the gate 14 and admits compressed gas from a container 16 to an inflatable safety bag 17. The two transmitting aerials 2R, 2L may be replaced if desired by a single centrally located transmitting aerial, and three-part circulators may be used instead of the directional couplers 4R, 4L.

Abstract: 277,142. Hall, J. A., and George, W. F. C. July 5, 1926. Roasting granular materials; treating with air and gases; treatment by damping; treatment by steaming.-Grain is subjected to a succession of alternating hot and cold treatments produced by air circulation between ducts in the grain with or without the addition or extraction of moisture during such treatments with the air during some or all of such treatments being circulated in a closed circuit through the grain and a heater or a cooler back to the grain. The grain travels downwards through a tower a that may be similar to that described in Specification 238,375 in which air ducts in rows c, d are placed one above the other, such ducts being open on the underside. The ducts are divided into four groups A, B, C, D, the groups A, C being coupled up to a fan e and a heater g and the groups B, D to a fan f and a cooler i that may be in the form of a water spray and that may act to extract moisture from the air. A dust extractor, a moistener in the form of a steam jet, or a combined dust extractor and moistener may be arranged in the hot air circuit at h. A condenser in the form of a cold water spray may be fitted in the hot air circuit before the heater g to extract excess moisture. Some of the air in the hot air circuit may be replaced by fresh air drawn from the outer atmosphere. The grain may be dried as a preliminary process by passing heated air through it. Moisture may be added to the grain in the first heating section and be removed in the subsequent sections. Air may be drawn from the outer atmosphere and pumped through the grain in a final section to cool and to dry it. Each section may have its own heating or cooling device and pump. The apparatus may be used for par-boiling rice or for high heat treatment of grain, such as cooking maize whole or in grits, or broken wheat or semolina. In such cases the cooling section B is used for heating by fitting a bye-pass connection with a heater therein around the cooling device in the circuit. Grain that has been treated at high temperatures may be mixed with grain treated at ordinary temperatures.
