Title: Methods of and apparatus for cooking
IPC: A47J37/00
Filed: 1929-04-17
Abstract: 312,662. Cassidy, R. May 30, 1928, [Convention date]. Resistance ovens.-The reduction in the weight of food during cooking is used automatically to end the cooking-operation. In the apparatus shown, a piece of meat 1 is cooked in an oven heated by elements 33. The meat is suspended from a hook gripped between pivoted jaws 3, 4 pressed together by a spring 6. The jaw 4 carries an armature 7 which is pulled by an electromagnet 8, when cooking is complete, to open the jaws and release the meat. The, jaws and the meat are rotated by an automatic turnspit 10 which is suspended on a knife edge 12 on an arm 11 pivoted at 13 and pressed upwardly by a spring 16 on a screwed rod 15 which is vertically adjustable, according to the weight of the meat, by a nut 17 having a graduated scale 66. A stop 14 limits the downward movement of the arm 11. In operation, a contact 44 is adjusted on the clock face 42 of the time switch to the time at which cooking is to start. When the hour hand reaches the contact 44, a momentary current passes through an electromagnet 30 and a bellcrank switch member 28, 31 pivoted at 29, is swung to close the switch 27 against the action of a light spring 32. A second contact 45 is adjusted on the clock face to the time at which reduction of the heating current is desired. When the hour hand reaches the contact 45 the electromagnet 41 is excited and operates the rheostat 40 in the main heater circuit. As the meat loses weight, the arm 11 rises until a spring 21 of a switch arrangement 21, 22, 23 contacts with the arm 22 and completes the circuit of a heater 19 in a warming chamber 20. As the arm 11 rises still further the spring arms 22, 23 contact and excite the electromagnet 8 which withdraws the blade 28 from the main switch contacts 27 and also opens the jaws 3, 4 to release the meat. The switch 21, 22, 23 is carried on a screwed rod 24, vertically adjustable by a nut 25 having a graduated scale 67. The meat, when released, 'slides down the inclined plate 61, through a door 62 into a pan 64 in the warming chamber. When the meat is removed from the chamber 20 the heater 19 is switched off by the hand member 70. The heaters 33 are connected to the mains 35, 36, and the remaining electrical components are coupled to the mains through a transformer 37. The automatic controls need not be used, the switch 27, 28 then being operated manually by handle 71 and the rheostats 40 also being operated by hand.

Title: Process for the production of a Gas in the Gaseous State under Pressure in Variable Quantities, and in the Liquid State
IPC: F25J3/04
Filed: 1967-03-16
Abstract: 1,178,006. Gas liquefaction process. L'AIR LIQUIDE S.A. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE. 16 March, 1967 [25 March, 1966], No. 12473/67. Heading F4P. In a process for liquefying varying amounts of a constant supply of main gas, e.g. oxygen produced by a conventional air separating plant 2 by indirect heat exchange at 11 with an auxiliary gas, e.g. nitrogen in a closed cycle comprising a compressor 17 delivering through lines 18, 19 to an expansion turbine 20 which in turn discharges through the exchanger 11 in which the gaseous oxygen is liquefied and a return line 23 to the compressor 17, the degree of cooling of the exchanger 11 is varied in accordance with changes in demand for liquid oxygen by varying the pressure and hence the amount of nitrogen fed to the turbine but maintaining constant the ratio between the feed and exhaust pressures of the turbine. To reduce the cooling of exchanger 11, a portion of the compressed nitrogen is bled through a valve 26 to a storage vessel 24, and since the exhaust pressure of the turbine 26 is lowered the inlet pressure of the compressor 17 is correspondingly lowered. To increase the production of cold in exchanger 11, nitrogen gas is discharged from vessel 24 through a valve 25 to the inlet of compressor 17 with valve 26 closed, resulting in increase in inlet pressure to the turbine 20. Valves 25, 26 may be regulated manually or automatically in accordance with the setting of a valve 8 in a branch line 7 of the main gaseous oxygen supply line 6 by means of a control-unit 42 responsive to pressure in line 6. Make-up for the closed nitrogen cycle is obtained from the nitrogen product line 4 of the apparatus 2. To meet a peak demand for gaseous oxygen, previously liquefied oxygen is withdrawn from a storage vessel 16, vaporized at 33 and fed to line 6.
