Title: Refrigerating processes and apparatus for aging meats and storing vegetables
IPC: A23L3/3418
Filed: 1948-08-30
Abstract: 645,246. Refrigerating. HODGES RESEARCH & DEVELOPMENT CO. Aug. 30, 1948, No. 22837. Convention date, Oct. 27, 1947. [Class 29] In a refrigerator for ageing meat, cooled humid air is forced by a fan 33 past refrigerating coils 37 and over a wall 23 of an enclosure, part of the air passing through perforations in this wall across the enclosure to the opposite wall 24 and the rest of the air passing under the bottom 26 of the enclosure, the air being recirculated over the wall 24 back to the fan and refrigerating coils. Perforated walls 23, 24 spaced from the side walls 10, 11 of the refrigerator are joined by an imperforate false bottom 26 and by a plate 28 at the top, the wall 23 being extended at 29 to join a plate 30 apertured at 31 to take a fan 33. Above the plate 30 is an evaporator coil 39 fed by a refrigerating machine which, with the fan 33 and its motor 36, is carried by a top closure member 18 of the refrigerator. The fan draws air from the space between the walls 11, 24 and passes it over the evaporator coil 37 at a speed of from 750 to 1,000 feet per minute to minimize condensation, the cooled air passing downwards between the walls 10, 23 and into the chamber through the holes in the wall 23. Part of the cooled air passes beneath the false bottom 26 depending upon the setting of a damper 27. The velocity of the air through the chamber is approximately 70 feet per minute. A wheeled rack for the goods is shown in Fig. 4, supported at the height of the floor 26 by a wheeled truck 79 so that it can be pushed into the chamber without lifting. Slidable openwork shelves 102 are supported on the rack by rear rollers 105, 109 and front rollers 106, their movement being limited by stops 107. A removable pin 89 secures the rack to the truck. The refrigerating mechanism, Fig. 3, carried by the closure 18 comprises a compressor 40, oil filter 45, condenser 43, drier 50, visual flow indicator 51, solenoid valve 52, expansion valve 54, and flooded evaporator tubing 39 leading to float chamber 58. Rise of liquid refrigerant in the float chamber 58 causes a mercury switch 62 to close the solenoid valve 52 and stop the feed of refrigerant to the evaporator. A back pressure regulating valve 64 is arranged in the return vapour line 65 which is connected to a surge tank 66. A thermostat 71 switches on the fan 33 when the evaporator 39 reaches a predetermined temperature. For cooling vegetables the damper 27 is fully opened, reducing the velocity of the air through the chamber to about 10 feet per minute. The door may be provided with glass panels.

Title: Stopping device for automatic lathes
IPC: B23B13/06
Filed: 1962-06-14
Abstract: 985,946. Lathes. E. C. HAHN, [trading as INDEX-WERKE KOMM. GES.]. June 14, 1962 [June 15, 1961], No. 22975/62. Headings B3B and B3T. Means for stopping a lathe when the bar stock 38, fed by cams 30, 32, is used up comprises a switch &c. 40 which must be operated by the returning feed-device 25 before the machine can be stopped by a device 44. A reciprocating gripper 24 in the spindle and a release mechanism for the chuck 22 are operated through levers 34, 36 by the cam tracks 30, 32. A spring 48 acting on the lever 34 biases it in the return direction so that after the gripper 24 has slipped off the end of the stock, the feed-slide 25 is returned an extra amount by the spring and operates the initial switch 40. The extra movement is accommodated by a recess (not shown) in the track 30. The camdrum continues to rotate until an adjustable dog 42 on the drum contacts the device 44, which disengages a clutch in the drive and applies a brake. In a modification, Fig. 3, with an external feed gripper 50 and an auxiliary feed-rod 58 which may be swung into position to continue the feed after the gripper 50 has slipped off the rod, a further conditioning switch 64 is operated by a collar on the feed-rod at the end of the supplementary feed. The machine is then stopped when the dog 42 encounters the device 44.

Filed: 1972-05-17
Abstract: 1372917 Self-balancing bridge R A RUEHLE 17 May 1972 23057/72 Heading G1U An amplifier 6, connected across the diagonal of a bridge 1, 2, 3, 4, feeds a second amplifier 8 which applies a feedback current Ic8, either directly or via a current indicating device 9, to one diagonal of the bridge so that either the potential across, or the current flowing between, the diagonal points of the bridge is maintained at a constant non-zero value. An alternative output from the bridge can be taken from across the emitter load 10. The bridge is useful for measuring an unknown resistance 1, which may be temperature responsive, and it may include ambient temperature variation compensation elements such as a diode 30 and/or a thermistor 40. Alternatively the amplifier 6, which like all transistors is temperature responsive, may be used as a temperature probe.
Patent GB-502963-A (GB)
Title: Improvements in measuring apparatus combined with calculating mechanism
IPC: G01G19/413
Filed: 1937-08-23
Abstract: 502,963. Weighing-apparatus. COUFFIGNAL, P. L., and VORMS, A. Aug. 23, 1937, No. 23102. Convention date, Aug. 25, 1936. [Class 143] [Also in Group XIX] A computing weighing scale is combined with a calculating mechanism having means to express the data in the binary notation and to effect the multiplication process in the binary system, the result being translated into the usual decimal system or other notation such as English monetary units. The apparatus comprises two binary reading devices, one of which is adjusted in accordance with the weight through the intermediary of a coupling device associated with the pointer 1, Fig. 1, of the weighing scale, and the second device is set by the manual depression of keys to represent the unitary price value. The set up devices coact with an electric circuit arrangement, including sets of relays, to sum the partial products obtained in each binary denomination. Thereafter a translation mechanism is effective to convert the binary product, denomination by denomination, to the equivalent value in the decimal or other notation. The weight, price per unit, and total cost are viewable through apertures in the casing on drums VI, V2 and V3. In. the weighing scale shown, means are provided to apply compensation weights automatically. These weights 111, Figs. 1, 12 and 13, are mounted on spring controlled levers 122 held in the raised position by latch means 125 controlled by solenoids 126, 126<1> arranged in parallel. The latch means are guided in a plate 128 and controlled by springs 127. The latch'126 of the solenoid 126 controls a pair of contacts 132, 133. As the indicating pointer reaches the end of its travel it closes a contact 131 connected with a terminal 134 to energize the first solenoid and release its latch to permit the weight to fall on to the plate 110. If this additional weight is not sufficient the solenoid 126 remains energized and circuit is completed through the contacts 132, 133, to close the circuit of the second solenoid whereupon its weight is allowed to fall. The levers 122 co-operate with a pivoted arm 135 carrying a oontact that co-operates with contact bars on a sector 138 that are connected to relays in the binary reading device to set up representations of the binary orders corresponding to the additional weight. At the end of a weighing operation a connecting rod 141 may be operated, and through levers 140 effect the lifting of the weights 111 to their inoperative position. The operation of the rod 141 may be effected electromagnetically upon the indicating pointer reaching its zero position.

Title: Improvements in or relating to Sorting Apparatus
IPC: B07C5/36
Filed: 1968-05-15
Abstract: 1,198,224. Conveying articles. HONEYWELL Inc. 15 May, 1968 [15 May, 1967], No. 23123/68. Heading B8A. Articles 20 on a conveyer 18 are passed successively through two stations at which they are subject to testing devices 26 and 27 respectively, and a sorting station 28 at which they are allowed either to proceed on the conveyer or to be deflected off it. According respectively as to whether they (1) pass the tests at each of the stations or (2) fail the test at. either or both of the stations. Each testing station 26, 27 furnishes a pressure impulse along respective conduits 29, 30 if the result of a test is negative. The ends of the conduits terminate beneath a rotary table 50 carrying bi-stable fluidic memory devices 40, 41, 42. Each of the latter comprises an input 55, Fig. 3, leading from a common pressure conduit 52 associated with the table 50. There are two pressure outlets 46 and 47, only one of which is operative at a time, dependent upon a preceding pressure impulse applied at either of two respective control inputs 44, 45. The input 45 overlies a respective slot in the plate 50 so as to receive any impulse present in the conduits 29, 30 as the plate 50 rotates. The outlet 46, during rotation of the plate 50, makes momentary connection with a conduit 71 which leads, via a fluid amplifier 32, to the input of the sorting station 20. After each memory device 40-42 passes the conduit 71 its control input 44 passes a pressure conduit (75) (Fig. 2, not shown) which results in resetting the memory to restore its pressure to the outlet 47.
