Title: An improved method of toasting bread and the product resulting therefrom
IPC: A47J37/08
Filed: 1938-07-26
Abstract: 516,508. Toasting bread. STEVENS, A. H. (Brooks, Ltd.). July 26, 1938, No. 22189. Drawings to Specification [Classes 28 (i) and 49] Oil or fatty substance is applied to one or both sides of a slice of dried bread and the slice is then toasted under pressure between hot plates. Drying for from 5 to 7 days until the moisture content is about 25-30 per cent., application by spraying of hydrogenated oil or fat heated to about 100‹F., and a cooking temperature of 350-450‹F. are referred to as satisfactory. The oil applied may vary from 1¢ lbs. to 4 lbs. for 100 lbs. of bread and is allowed to penetrate into the bread for from 1¢ to 2 hours. The cooking-plates are traversed in a series in circular manner through an oven, automatic means being provided for lifting the top plate for loading and unloading. The pressure applied is such that the thickness of the slice is reduced from 2- to “ inches. The cooking time is from 3 to 5 minutes. The top plate is lifted during the final one-third or two-fifths of the travel through the oven to permit free escape of moisture from the plates and to obtain a more uniform colouring of the toast by an exposure to the oven atmosphere. The plates may have ribs or protuberances which penetrate into the slice to increase the heating surface in contact with the bread, thereby to effect a more thorough dextrinization of the starch, and to produce score lines to facilitate the breaking of the toast into sections. Flavouring oils, e.g. oil of sesame seed, or oil from poppy seeds, either alone or mixed with other oil or fat, may be used, or flavourings may be added to the slices either before or after the oil application, e.g. by sprinkling sesame, caraway or poppy seeds, or cheese, nuts, or chopped fruits over the surface of the bread before pressure and heat are applied.

Inventor: COLLARD JOHN
IPC: H01P5/02
Filed: 1947-08-20
Abstract: 650,615. Wave-guides; impedance transformers. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 20, 1947, No. 23047. [Class 40 (viii)] A length of waveguide of rectangular cross-section is joined to a load impedance through a transformer section of wave-guide of different crosssectional dimensions to the first length, these dimensions being so chosen as to match the impedance of the load to the characteristic impedance of the wave-guide. The calculation of the required dimensions is discussed in connection with the transmission of H 10  waves and the transforming section is a one quarter wavelength. In addition to the normal transforming action of a quarter wavelength section there are two transformer effects due to the change in the longer dimension of the crosssection of the guides at each end of the transformer. and four shunt reactances produced by the changes of each dimension at each end. The latter reactances can, however, be ignored if the characteristic impedance of the waveguide differs widely from that of the load. In the construction a length of guide 1 is connected to a load 2 through a transformer 3. By effecting changes in the short " b dimension and maintaining the long " a " dimension unaltered, the transformer effect due to changes in the " a " dimension is eliminated. Specifications 572,881 and 650,614 are referred to.

Title: Improvements relating to the control of electrically operated hoists and winders
Inventor: MULLIGAN JOHN WESLEY
IPC: H02P3/22
Filed: 1951-10-03
Abstract: 704,481. Control of A.C. motors. METROPOLITAN-VICKERS ELECTRICAL CO, Ltd. May 1, 1952 [Oct. 3, 1951], No. 23080/51. Class 38(3) A control system for electrically operated hoists or the like has the speed of an alternating current driving motor regulated by a liquid controller which is adjusted by a positional servo mechanism during both the driving and dynamic braking operations, the servo mechanism having two phases in its operation during both driving and braking; firstly, a rapid movement to adjust the liquid controller to a value to give maximum starting or maximum braking torque as the case may be and secondly, a much slower movement over the remaining portion of the motor operations. During driving the driver's control lever is moved to the " full on " position thus moving the hollow sleeve 3, by means of a lever 6, so that the port 7 is closed by movement of the sleeve 3 into the piston 2. Pressure, fluid thus acts on the piston via the port 10, hollow sleeve 9 and the cylinder 8; the valve 16 being open and the valve 17 being closed during the driving operation. Since the full fluid pressure acts on the piston 2, it moves rapidly to move the lever 1 to adjust the position of a liquid controller to give maximum driving torque. At some point in the travel of piston 2 and the sleeve 3 a link 11 becomes operative to move the sleeve 9 to close the port 10 so that the pressure fluid can now only act upon the piston 2 by way of a reduced orifice 13. The pressure on the piston is therefore reduced and consequently the piston moves more slowly over the remaining part of the motor controller range. To initiate dynamic braking the driver's control lever is moved to the " braking " position when the valve 16 will be closed and the valves 17, 18 will be opened thus admitting fluid under full pressure to the piston 2 by means of a port 14, thus the piston 2 moves rapidly to reduce the value of the liquid controller in the rotor circuit. When the rotor current reaches a pre-determined value, means, such as electromagnetic relays, or a saturable inductor, energized by current transformers associated with the rotor phases, become operative to close the valve 18 so that the fluid supplied to the piston 2 has to pass through an adjustable valve 21 which limits the fluid pressure so that the piston again moves at a slower rate. The means operating to close the valve 18 may alternatively be associated with the stator circuit. Specifications 651,379 and 690,090 are referred to.
