Title: Apparatus for supplying groups of cigarettes
IPC: B65B35/40
Filed: 1974-01-23
Abstract: 1465202 Packaging apparatus FOCKE & PFUHL 23 Jan 1974 [26 Jan 1973] 3212/74 Heading B8C In cigarette transfer apparatus in which a two compartment receptacle 22 is reciprocably driven between first and second positions at each of which one compartment 22 or 23 is charged with a group of cigarettes from one of two magazine outlets 15 and 16 by a respective one of two reciprocating ejectors 19 or 20 whilst a previously charged group in the other compartment is discharged into one of a plurality of pockets of a rotary turret 13 of a packaging machine by a common pusher 28 reciprocating at twice the rate of the ejectors, the group of cigarettes in the charged compartment is compressed during movement of the respective compartment from the charging position to the discharge position. As shown, the receptacle is formed by upper and lower relatively-displaceable recessed members 29 and 30 interconnected by parallel links 39 and 40, the arrangement being such that as each charged compartment moves from the charging to the discharging position, the members 29 and 30 are laterally relatively displaced to reduce both the width and height of the compartment and thus compress the cigarattes therein. The receptacle, ejectors and pusher are all driven from a common drive shaft 40 which also effects the relative squeezing displacement of the recepticle members 29 and 30 through cams 53 and 54, followers 54 and arms 36 and 38. In a modification, Fig. 9 (not shown), squeezing of the cigarette group with the respective compartment is effected by spring-loaded plungers 56 co-operating with stops 59, which are reciprocally movable with the receptacle to effect displacement of the plungers during movement of the receptacle but which do not act on the plungers when the receptacle is at its first or second positions.

Abstract: 1419656 Logarithm circuits IWATSU ELECTRIC CO Ltd 23 Jan 1973 [2 Feb 1972] 3313/73 Heading G4G [Also in Division H3] An A/D converter for supplying the value of log V 2 /V 1  comprises a capacitor 14 which is charged up to the value V 1  at the start of the measuring cycle and is then caused to discharge through a resistor R until its voltage is equal to V 2  or determined by a comparator 21 as shown, at which point a signal from the comparator stops a reversible counter 25 counting clock pulses from a source 26 to digitize the discharging interval, whereupon the capacitor is discharged to zero and together with amplifier 20 is caused to integrate a reference voltage V, from a source 16 for a time equal to the discharging time as determined by the counter 25 counting back to zero. It is shown that where V o  is the output at 10 at the end of the measuring cycle. Thereby the absolute values of R, C and the pulse period of source 26 are eliminated from the measurement. The control of switches SW1-SW6 which create the different parts of the measuring cycle is by means of device 24 with forward and feedback connections with the counter 25. The output V o  of the circuit is taken with the value V R  to a conventional dual-ramp A/D converter and the value V o /V R  digitally derived. By a suitable choice of V R1  the log V 2 /V 1  may be directly read from the output of this converter.

Filed: 1955-02-07
Abstract: 778,176. Control systems for vehicle heating. VOIGT & HAEFFNER AKT.-GES. Feb. 7, 1955 [Feb. 6, 1954; March 22, 1954], No. 3610/55. Drawings to Specification. Class 38 (4). In a heating system for a vehicle controlled as in Specification 778,175 by an electrically actuated adjustable cycling switch which periodically switches on and off the supply of heating medium (which may be electricity, steam, gas, hot air, or exhaust gas) the setting of the cycling switch is now automatically controlled in dependence upon the outside temperature, with, or without, further automatic control of heating in dependence upon the inside temperature. Thus, a cam for adjusting the setting of the switch may be actuated by an electric motor under the control of a positioning switch moved in correspondence with changes of outside temperature by an external bimetal spiral, whilst an internal thermal switch may become effective upon the interior of the vehicle reaching a predetermined temperature to cause the cycling switch to interrupt or reduce the supply of heat. Alternatively, there may be two cycling switches controlled by a single external temperature detector but arranged to provide different degrees of heating, there being provided also an internal thermal switch which selectively places the vehicle heating system under the control of one or the other of the cycling switches, according as to whether the interior temperature is above, or below, a predetermined value.
