Title: Unblanched frozen vegetables
Inventor: LONERGAN DENNIS
IPC: A23L19/00
Filed: 2009-12-15
Abstract: A method of freezing vegetables without the need to blanch the vegetables prior to freezing. Vegetables 14 to be frozen are placed in an oxygen impermeable container 10 and oxygen within the headspace 12 and within the plant tissue are both depleted. The oxygen depletion may be acomplished by vacuum packing the vegetables and then removing any remaining oxygen allowing the vegetables to respire for a period of time prior to freezing. The remaining oxygen may also be removed by the addition of enzymes that consume oxygen and which may be known as oxygen scavengers. Frozen vegetable packages depleted of headspace 12 oxygen and internal oxygen are also included in the present invention.

Abstract: 541,787. Moulding sliding clasp fasteners by injection. LIGHTNING FASTENERS. Ltd. (Talcon, Inc.). June 10, 1940, No. 10082. [Class 87 (ii)] [Also in Group XXII] Plungers 18 exert pressure on the material in the mould cavities 7 formed by two co-operating mould parts 3, 4, the pressure being maintained until the injected material, e.g., thermoplastic or thermo-setting material or low - melting - point alloy, has solidified. The mould parts enclose a fabric tape 1, on to the edge of which the fastener members 2 are directly cast by the mould. As shown, the mould moves along the tape, one plunger 18 being provided for each mould cavity, the mould cavities being isolated from each other, but in a modification, the mould is stationary and there is only one plunger which is common to a series of inter-connected mould cavities. The mould 3, 4 moves through a guideway 11 having a stationary injection nozzle 10 opposite which are brought in turn openings 9 leading to the mould cavities. As each cavity is aligned with the nozzle its plunger is raised against the action of a spring 21 by a cam 22, and when the cavity moves out of alignment, and away from under the cam, the spring returns it. Recesses may be formed in the members 2 by using cones or by drilling after moulding.

Title: Apparatus for the liquid-phase epitaxial growth of multilayer wafers
IPC: C30B19/06
Filed: 1972-03-06
Abstract: 1344437 Liquid epitaxial deposition MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 6 March 1972 [5 March 1971] 10286/72 Heading B1S [Also in Division H1] In the formation of multilayer wafers by the epitaxial deposition of one or more layers on a semiconductor substrate the deposition is carried out by using a horizontally-positioned refractory furnace tube containing a boat which includes at least two baths aligned in a direction parallel to the central axis of the tube for the semiconductor material to be deposited and a column-like member with its longitudinal axis parallel to the central axis of the tube and which includes means for holding the substrate, means for flooding the substrate with the semiconductor material and means after epitaxial growth for removing the substrate from the material and draining off residual material. As shown, a cylindrical boat 41, which contains a longitudinal groove 42 which engages a claw member 43 secured to the furunace wall 40, is fixed in the furnace in the circumferential direction of tube 40 but is slidable in the longitudinal direction. The boat 41 contains two baths 45a and 45b which communicate with bore 44 and contain solutions of semiconductor materials. Into bore 44 is inserted columnar holding member 48 which holds substrate 50 in recess 51 by clamping member 52. Stopper 53 limits movement of member 48 and a push rod 55 connected to the boat 41 moves the boat only to elthft.e]tat the boat 41 moves the boat only to the left. Bore 37 of the boat contains a thermocouple 54, positioned over the substrate. In operation the substrate overlies the bath 45a carrying the solution 46a. After heating the substrate and solution the furnace tube 40 together with the boat 41 are rotated through 180‹ and the substrate flooded with the solution 46a. The solution is cooled whereby the substance in the solution deposits on and grows on substrate 50. When the desired thickness of growth is achieved furnace tube and boat 41 are rotated through 180‹C whereby the substrate 50 is separated from the solution and under gravity flow, is freed from non-deposited solution. The boat 41 is then slid left by push rod 55 until the substrate 50 overlies the bath 45b and the solution 46b when the deposition cycle is repeated. In a modification the boat only is rotated. Exemplified solutions are (i) gallium arsenide dissolved in gallium and containing small amounts of aluminium and silicon, (ii) gallium phosphide dissolved in gallium and containing small amounts of tellyrium and zinc, and (iii) gallium arsenide dissolved in gallium and containing small amounts of aluminium. zinc, tin, and silicon. The substrates specified are formed of n-GaAs or n-GaP.

Title: Improvements relating to the reception of radio signals
IPC: H04B1/26
Filed: 1921-04-07
Abstract: 161,580. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Weagant, R. A.). April 9, 1920, [Convention date]. Heterodyne receiving Systems; thermionic detectors; audible reception of unmodulated continuous waves.-Locally generated oscillations having a frequency differing widely from that of the incoming signal energy are combined therewith to produce intermediate frequencies equal to the sum and difference of the original frequencies, and these intermediate frequencies are again combined to produce final frequencies which are double the original frequencies. The lower of these final frequencies is received in the telephone, the others being excluded so that the telephone note is always independent of the signal frequency. Signal energy of 25,000 cycles in the aerial 1 is combined with local oscillations of 500 cycles from an alternanator 5. The circuit 9 is tuned to a frequency of 25,000, and will therefore pass the intermediate frequencies of 25,500 and 24,500, whilst blocking the frequency of 500 from the source 5 during the time that no signals are being received. The intermediate frequencies in the circuit 9 appear as final frequencies of 50,000 and 1,000 in the plate circuit of the valve 10, and the latter fre- .quency alone actuates the telephones 11. As shown in Fig. 3, the locally-produced oscillations consist of one frequency of 50,000 generated by the valve 12, modulated by a low frequency of 500 supplied from an alternator 5 and applied directly to the plate of the valve 12. Two of the intermediate frequencies thus produced will have a value of 24,500 and 25,500 as before, and the circuit 9 being tuned to a frequency of 25,000 will pass these, whilst excluding the local frequencies of 50,000 and 500. In a further modification, two local valve oscillators impose frequencies of 50,000 and 50,500 upon incoming signals of 25,000 cycles, again giving rise to an indication of 1,000 cycles in the telephones so long as signals are being received by the aerial.
