Patent GB-1522333-A (GB)
Title: Electrical battery charge monitoring circuits
IPC: G01R17/10
Filed: 1975-10-01
Abstract: 1522333 Measuring battery state of charge STILL GmbH 1 Oct 1975 [2 Oct 1974 30 April 1975] 40109/75 Heading G1U [Also in Divisions H1 and H2]  A battery charge monitoring circuit comprises a resistor 12 for sensing the battery discharge cur-  rent and connected to a resistor network 36-41 which responds to the battery voltage to produce via an amplifier 22 a signal representative of a current compensated battery voltage level, and a comparator 19 which receives the signal and actuates a timing device 3, 5 when the state of charge of the battery is below a predetermined level, the timing device being arranged to operate a display 4 and/or a control device when the timing device has been actuated for a predetermined time. The battery is connected across terminals 10, 80 and the discharge current flows through the resistor 12 in  series with the load. The comparator 19 is supplied with an input dependent on the battery voltage and adjustable by a resistor 47 and an input from the network 36-41 via the amplifier 22, which input compensates for the voltage drop in the battery when the battery is under load. If the battery is in a charged state, i.e. if a primary display device 9 is in a green sector, the output of the comparator 19 prevents operation of a pulse generator 3 and a light emitting diode 4 remains dark. The outputs 54-56 of a counter 5 enable a transistor 20 to conduct via inverters II-V and a relay 6 is energized. The relay contact (not shown) is therefore closed and may be the main switch of a vehicle such as a fork lift truck, or the switch for the drive movement or the switch for the motor driving the pump of the hydraulic lift mechanism. If the battery is in a discharged state, i.e. if the display device 9 is in a red sector, the output of the comparator 19 causes the generator 3 to supply pulses at a frequency of 1À5 Hz to the counter 3. The diode 4 is flashed and after 512 pulses have been counted by the counter 5, the transistor 20 is switched off by the counter via the inverters II, V. The relay 6 is therefore de-energized to disconnect the battery from all or only certain of the loads after the battery has been operated in its discharged state for the time taken to count the 512 pulses. In a modification, the measuring resistor 12 is replaced by a magneto-resistive differential sensor.

Abstract: 1,179,418. Removing fat from meat. W. E. JOHNSON. 28 Nov., 1967 [9 Sept., 1966], No. 40411/66. Heading A2U. A method of removing fat from deformable meat, e.g. in the processing of pork to bacon slices having peripheral fat of constant width, comprises deforming the meat such that the fat/muscle boundary is of substantially regular configuration (e.g. planar) and in a known position, and then removing fat external to a surface having a predetermined relationship relative to the fat/muscle boundary. The method may be carried out by placing the meat on a deformable sheet of neoprene above which is arranged a plurality of probes which can sense the fat/muscle boundary of the meat by the difference in the electrical conductivities of the fat and muscle, each probe being operatively associated with a deforming means, e.g. a pneumatically, hydraulically or mechanically operated ram, positioned below the sheet. The probes are then moved into the meat until one probe detects the fat/muscle boundary. Each of the rams not associated with that probe are operated to act on the sheet and meat till the fat/muscle boundary contacts the associated probe. The boundary is then in contact with the all the probes and is in a known position. The desired fat is then sliced off. The meat may be placed with the fat or muscle upwards. The probes may be stationary and below the meat. The deforming means may be above and/or below the meat. The sheet may be omitted, the deforming means also supporting the meat. The deforming means may operate by suction.

Abstract: 992,284. Rolling. SCHLOEMANN A.G. Nov. 6, 1962 [Nov. 6, 1961], No. 41912/62. Heading B3M. A roll stand comprising a closed frame 1 housing roll carrying chocks 4 and 6 is provided with a high pressure prestressing element 2 and also with rotatable hollow spindles 13 which take over the initial stressing. In operation, the element 2 is operated to prestress the frame and chocks, and then the spindles 13 are rotated in threaded inserts in the frame by means of worms 11 and gears 12, so that the spindles abut the upper chocks 4 and take over the prestressing force, the element 2 then being released. For pass adjustment or roll removal, the element 2 is re-applied, the spindles 13 raised clear of the chocks 4 by the worms 11, and the element released. The rolls are then free for removal or adjustment. For pass adjustment, pressure fluid is admitted through pipes 14a to force spring-urged pistons 15 downwardly until toothed portions 16a and 18a engage. Rotation of the worms 11 now causes rotation of the pistons 15 and of cup-shaped members 18 in the upper chocks. The members 18 engage externally threaded pins 19 to thus move the upper and lower chocks relatively to one another. Scales 20 indicate the adjustment made. The fluid pressure in piston 14 is released and the prestressing force re-applied. Entry and exit guides 8 and 9 are slidably mounted on bars 6a of the lower chocks.
