Abstract: 1315434 Measuring bearing friction ERNO RAUMFAHRTTECHNIK GmbH 2 July 1971 [6 Nov 1970] 31212/71 Heading G4H - During a first fixed time interval T, with the drive to a bearing switched on, pulses representing the speed of the bearing each result in a predetermined numers of pulses being accumulated in a counter 50 (Fig. 2) positively and during a second identical time interval T, with the drive to the bearing switched off, pulses representing the speed again each result in the same predetermined number of pulses being accumulated in the counter but in this case negatively, the difference count at the end of the second time interval representing the friction of the bearing. As described after a start signal is generated a gate 30 is enabled so that the next pulses from a sensor detecting the speed of the bearing sets a bi-stable 33 to enable a gate 32 to pass clock pulses to both counter 50 and a decade counter 21, 22, 23. When the decade counter reaches the count set up on switches S1, S2, S3 bi-stable 33 is reset to close gate 32, the process being repeated at subsequent sensor pulses until a counter 40 also receiving the clock pulses via a gate 31 enabled by the start signal reaches a preset count to terminate the first time interval T when (1) a bi-stable 23 is reset to close gate 30, (2) a bi-stable 22 is reset to switch counter 50 over to negative operation and (3) a bi-stable 21 is set to switch off the drive to the bearing. When the drive is switched off a "repeat" signal is generated and the process is repeated except that the counter 50 is now decremented during the second time interval. The count at the end of the second time interval may be displayed.

Title: Process of producing yeast without alcohol
IPC: C12N1/18
Filed: 1930-10-20
Abstract: Yeast is produced without alcohol by a two-stage process.  In the first stage a well fed yeast and a considerable amount of alcohol are produced, while in the second stage the yeast is forced to assimilate the alcohol formed in the first stage.  The yeast is propagated by the usual discontinuous process in a sugary nutritive with slight aeration.  The yeast is then separated from the wort, diluted with water and strongly aerated, propagation of the yeast being effected by adding the separated alcoholic wort during a considerable time in a periodical or continuous manner and with continued aeration. Sugary and amylaceous raw materials as well as sulphite lye or wood sugar solutions may be used as nutrients in the first stage.  The alcoholic wort may be submitted to a disinfecting filtration before it is added to the yeast as a nutrient.

Abstract: 1350426 Comparator HONEYWELL INFORMATION SYSTEMS Inc 5 July 1971 [20 July 1970] 31470/71 Heading G4M A comparator 500 has a plurality of stages, a low Compare 200, a High Compare 201, an Equal Compare 202 and a Strobe 203. The low compare receives serially corresponding bits A, B of two numbers to be compared at an AND gate 13.2 which feeds an amplifier 1.2 and a gate 50.2. A reset signal feeds a gate 14.2 and the gates 50.2, 14.2 are ORed together and fed to an inverter 2.2. The inverter feeds an AND gate 18.2 which is ORed with the output of gate 17.2 and feeds an amplifier the output of which is fed back to AND gate 18.2. A Lo set interrogation signal fed to the amplifier is stored in the amplifier if AND gate 18.2 is enabled by the inverter 2.2. A similar circuit in the High Compare 201 receives inputs A, B and an interrogation signal Hi set. The Equal Compare stage 202 receives the outputs of amplifiers 1.2, 3.2 and an Equal set interrogation signal. The strobe stage 203 receives the outputs of amplifier 1.2, 3.2 and feeds a latching amplifier 9.2 which retains a stored "1" via gate 32.2 when a miscompare is sensed and fires flip-flop 10.2 to enable AND gates 24.2, 22.2, 21.2. When a comparison is required the appropriate question Lo set, Hi set or Equal set is stored and the corresponding bits of data are applied. In Low Compare an A > B condition extinguishes the stored "1", A<B retains it. In High Compare B>A extinguishes the stored "1", B#A retains it. In Equal Compare the stored one is extinguished by either A>B, or A<B and is only retained for A=B. The equal compare stored "1" is fed direct to the output amplifier 11.2 and retained via AND gate 24.2. The other outputs are enabled by the strobe pulse only when an inequality occurs. The comparator may be used to update records from punched cards to magnetic discs or drums via a core or solid state memory (Fig. 1, not shown).

Abstract: 1,190,996. Measuring bridge circuits. SIPPICAN CORP. July 7, 1967 [July 11, 1966], No.31482/67. Heading G1U. A bridge circuit is such that when balanced, i.e. providing zero output, the current flow through it is inversely proportional to the resistance R I , e.g. that of a thermistor, being measured. The bridge supply current I is derived from the output of a differential feedback amplifier A whose input is supplied from the bridge output terminals. A reference voltage source E REF  is connected in the bridge arm containing R X , in a direction opposing the voltage drop across R X  due to the supply current. At the balance achieved by the operation of the feedback amplifier, <SP>1</SP>/ RX  = <SP>I</SP>/2E REF , of the feedback amplifier, <SP>1</SP>/ RX  = <SP>I</SP>/2E REF ,  so long as the reference arms R 1 , R 2  are equal <SP>I</SP>/ 2  flows through each bridge branch. A value proportional to <SP>I</SP>/ E   REF  is automatically determined by a separate servo-system driving the contact of potentiometer P1 to a position r such that the input to the servo amplifier, <SP>1</SP>/ 2 IR 2  - rE REF  is zero, i. e. r = R2/2 I/E REF .

Abstract: 1459531 Nut runners ROBERT BOSCH GmbH [17 July 1974] 18 July 1973] 31711/74 Heading B3N A power tool incorporates a motor and has a torque responsive means, between the motor and a tool receiver, which comprises a plurality of axial recesses in the tool receiver, a first member under the action of a spring, a second member connected to the motor and balls arranged to be freed into the axial recesses by the spring acting on the first member, the balls being mounted for rotation with the second member, whereby on achieving a predetermined tightening torque, the balls move axially out of the axial recesses and thereby release means which act to switch-off the motor. In the embodiment of Fig. 1 coupling shaft 24 is drivingly connected to shaft 21. Shaft 24 has a flange 35 with holes 34 therein. Balls 33 are mounted in the holes and drivingly engage in conical detents 32 in tool receiver 25. Pressure plate 37 biases the balls into the detents by spring pressure. Stepped piston 45 is connected to shaft 48 and is biased forwardly by spring 52. In operation the tool is engaged with a nut and pressed thereon so that the parts move against the pressure of spring 53. This causes shaft 48 to engage rod 16 which in turn opens valve member 15. At the predetermined torque balls 33 are forced out of the detents and move plate 37 rearwardly. This allows balls 44 to be moved out by piston 45. Movement of the head forwardly allows rod 16 to be moved forwardly by pressure of spring 13<SP>1</SP>. Valve member 15 shuts off the motor. In the embodiment of Fig. 2 driving member 67 directly drives tool receiver 81 via balls 84 that engage in grooves 87 in the driving member and conical detents 83 in the tool receiver. Coupling sleeve 72 is biased forwardly by pressure of spring 76. The pressure is adjustable by nut 74. At the predetermined torque the balls move out of the detents and move the coupling sleeve rearwardly. This allows balls 70 to be forced outwardly by pressure of spring 63 on rod 69. The forward movement of the rod 69 allows valve member 63 to shut off the motor.
