Title: Production of meat emulsions
IPC: A23L13/40
Filed: 1961-03-01
Abstract: In preparing emulsions in which fat of meat is dispersed in the comminuted lean meat, at least one part of glucono delta lactone is added to 3200 parts of the meat just before or during the emulsifying, the emulsifying being in this manner accomplished without adverse lowering of the pH, and the gluconic acid which then is produced by hydrolysis of the glucono delta lactone diminishing the pH to enhance the red meat colour and maintain it. Dry glucono delta lactone may be added together with an edible substance having a capacity for moisture absorption greater than the glucono delta lactone, e.g. paprika, sodium chloride, sugar, sodium caseinate, a sodium soya bean proteinate, meat curing salt.  In emulsifying the meat, an alkali metal nitrite may also be added for curing, and, preferably, ene-diol compounds such as reductone, dihydroxymaleic anhydride, d-glucoascorbic acid, ascorbic acid, d-isoascorbic acid, and their sodium and calcium salts.  Examples are of tests on sausages stuffed with emulsions of pork and of beef and pork, ice chips, corn syrup solids, sodium chloride, curing salt of sodium chloride, sodium nitrite, and sodium nitrate, spice seasoning, e.g. paprika, red pepper and oleoresins therefrom, and sodium isoascorbate.

As shown, in the shear of the Parent Specification 1,446,206 which has two blade pairs, at right angles to each other for notching corners, force is also applied to the blocks 33, 34 in the direction of arrows 52 to maintain the clearance CF between blades 36U and 36L. The blocks 33, 34 bear on guide blocks 43, 49, and 42, 48 respectively which are adjustable by means of wedges 41, 47 and 39, 46. Wedge 41 is movable by means of a screw 148 driven by engagement of a worm in a gear box 151 with a pinion on the screw shaft. Wedges 39, 46, 41 are similarly adjustable by means of gear boxes 169, 168 and 154 respectively. The worms of gear boxes 154 and 168 are releasably connected by a shaft 171 and each worm has an extension such as shaft 176, Fig. 10, which can be rotated by a wrench 182 so that simultaneous adjustment of both wedges can be made at either end of the shaft (171). A shaft 173 allows similar simultaneous operation of gear boxes 151 and 169. The wedges are urged against the guide blocks by springs such as spring 162 urging the wedge 41 against the block 43. The force applied to the blocks 33, 34 to maintain the cutting clearances CS and CF comprise take-up blocks such as 198, Fig. 8, urged against the wedge 47 by hydraulic cylinders 199. A pivoted take-up block (204) is used to maintain the clearance CF at block 33 to save space. Shims are used in achieving an initial blade clearance which is registered on indicator dials 107 associated one with each of four gauge bushings mounted two in each plate (12) and (13), Fig. 1 (not shown), covering hold down assemblies. The gauge bushing 187, Fig. 10, houses a pin 196 which operates the dial 107 and is engageable with the face of the blade 36U. Subsequent adjustments are based on the reading registered using the shims.

Title: Synthetic Testing of High Power A.C. Electrical Circuit Breakers
Inventor: LONGWORTH DAVID PHILLIP
IPC: G01R31/333
Filed: 1967-02-20
Abstract: 1,186,435. Testing circuit breakers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd., ENGLISH ELECTRIC CO. Ltd., and A. REYROLLE & CO. Ltd. Jan. 31, 1968 [Feb. 20, 1967], No.8068/67. Heading G1U. A circuit breaker is tested over a make-break cycle in a system which simulates the sequence of normal duty voltage, short circuit current, transient recovery voltage and steady A.C. recovery voltage which would be encountered. The breaker S2 is connected to a first source circuit V which simulates the normal duty voltage and recovery voltage throughout the test. A switch S1 is automatically closed to connect the breaker to a second source circuit I simulating a short circuit current in response to a current flow, detected at D which takes place when the circuit breaker is closed to draw current from the first source. An oscillatory circuit including a pre-changeable capacitance C1 is operated to apply across the circuit breaker, when this is subsequently opened, a voltage simulating a transient recovery voltage. The steady voltage and current are derived from generators via chokes LR2, LR1 respectively and transformers T2 and T1. The steady voltage is applied to the test breaker S2 via a resistor R (for phase matching) and inductance-capacitance network TL for simulating the network between the supply and the breaker. The detector D may be a trigger plasma jet or laser beam source which, when current flow through the test breaker occurs on closure, initiates the closure of the breaker S1 so that the rated short circuit current is immediately applied. Breaker S3 is then closed and the breakers S2 (under test) and S1 are opened, at which time spark gap SP is triggered to connect across the test breaker the oscillatory circuit includes capacitor C1 and inductance L, to provide a waveform which simulates the transient recovery voltage, C1 being initially charged. A damping circuit L3 R3 is connected across the oscillatory circuit , while a rate control circuit C 2 R 2  is connected across the breaker to prevent spurious oscillations appearing on the injected current. The breaker S3 is subsequently opened so that only the steady recovery voltage V is finally applied across the breaker or alternatively the components L3, R3 may prevent C1 from resonating with T2.
