Title: Improvements in or relating to apparatus for handling rod-like articles such as cigarettes
IPC: A24C5/32
Filed: 1961-12-13
Abstract: 1,004,320. Cigarette making machines. MOLINS ORGANISATION Ltd., D. W. MOLINS and T. ROWLANDS. Dec. 13, 1962 [Dec. 13, 1961], No. 44646/61. Heading A2C. Apparatus for handling cigarettes comprises conveyers 9, 10A, 11 and 12 for conveying the cigarettes in succession in a direction transverse to their axes and a transfer conveyer 13 to receive cigarettes from the conveyer 11 and deliver them to the conveyer 12, the transfer conveyer extending obliquely from one to the other of the conveyers 11 and 12 and arranged to move with a component in the direction of movement of one of them, and having flutes extending obliquely across the transfer conveyer 13 to as to be substantially parallel with the axes of the cigarettes on the conveyers 11 and 12. The, conveyer 11 is a shoot and delivers the cigarette either directly, or via a suction wheel to the conveyer 13. The cigarettes are taken from the conveyer 13 by suction wheels on a shaft 40 over which run grooved chains 19 which deposit cigarettes on the conveyer 12 which, as shown, conveys the cigarettes in the opposite direction to the conveyers 9, 10A and 11. The cigarettes delivered by the conveyer 11 consist of cut double length units, the tipped ends of which face one another, one stream being reversed by means 23 adjacent the conveyer 12. If it is desired to effect an initial separation of the axially aligned cigarettes, two grooved suction drums 26 and 27 are interposed between the conveyers 11 and 13, the drum 26 being arranged to deposit the leading cigarette of a pair in a flute of the conveyer 13 before the drum 27 deposits the trailing cigarette in the same flute. The cigarettes are aligned by stops 30, 31. Alternatively, the initial separation of the pairs of cigarettes may be effected by a rotating disc located between the drums 26 and 27 which retards axial movement of the trailing cigarette of a pair (Figs. 7 and 8, not shown).

Title: Improvements relating to photosensitive apparatus
Inventor: WILSON GEORGE PETER
IPC: H03K17/795
Filed: 1961-12-19
Abstract: 1,038,086. Photo-transistor circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1962 [Dec. 19, 1961], No. 45471/61. Heading H3T. A photo-transistor PT is stabilized against temperature changes by connecting a diode D in the emitter circuit. At low levels of incident illumination I, PT passes a small current, hence the voltage developed across resistor R is less than the forward voltage of diode D. The circuit thus operates in a grounded-base mode and is insensitive to changes in temperature and illumination. As I is increased, the current passed increases until diode D becomes conductive when the circuit changes to the grounded-emitter mode and becomes more sensitive. A relay L is energized by further increase in I.

Filed: 1969-09-23
Abstract: 1277968 Gas meters DRESSER INDUSTRIES Inc 23 Sept 1969 [3 Oct 1968] 46799/69 Heading G1R [Also in Division G4] A device for correcting the indicated reading e.g. volume of a fluid meter so as to compensate for variations in temperature of the fluid is described. A shaft 17, driven by the output of the fluid meter, rotates a disc crank 11 through a shaft 12 and appropriate gears. As the crank 11 rotates it causes driving arm 30 to oscillate with a fixed arc about a shaft 24. A driven arm 32 is biased against a cam 35 by a spring 34 connected to arm 30 for part of the arm oscillation cycle until an L-shaped surface 36 on arm 30 drives the arm 32 in an arc away from the cam by an adjustable surface 33 Fig.2 (not shown). The cam 35 is connected to a bimetallic strip 80 which lies in the fluid such that fluid temperature variation causes the cam to rotate. Thus the degree of movement of the arm 32 during an oscillation cycle of crank 11 is varied by the cam position, i.e. fluid temperature. The arm 32 drives a counter shaft 24 connected to a counter index through a one way clutch, thus the counter index reading depends on the fluid temperature. In Fig.3 a driving arm 52 oscillates between C and D thus driving a driven arm 60 between E and F, the distance E-F varying with the position of a temperature adjusted cam 57. A temperature scale 82 with an intermittently acting brake 91 is provided, Fig.1, which stops the cam rotating while arm 32 is in contact therewith. The meter may be a fixed or constant displacement gas meter.
