Title: Method and apparatus for testing the filling of the ends of tobacco articles
Inventor: BAIER ANTON
IPC: A24C5/34
Filed: 1965-05-11
Abstract: 1,115,923. Testing cigarettes. K. KÍRBER. 11 May, 1966 [11 May, 1965], No. 19815/65. Heading A2C. A method for checking the filling in the open ends of cigarettes, cigarillos, and similar rod-like tobacco articles, or filters, is characterized in that the filling is checked separately at several cross-sectional end regions. As shown in Fig. 1 the cigarettes to be tested are carried in grooves in a suction drum 4. Testing devices 14 and 38 are provided opposite guide plates 12 and 36 and faulty cigarettes are ejected by a blowing nozzle 48. The testing devices, as 14, comprise four feeler pins of which three, 16, 18 and 19, are shown. Each feeler tests a quadrant of the end of a cigarette and is supported by four springs 24 and one spring 26, the free ends of which are connected to a casing 22. The casing 22 is provided with a cam follower 25 so that it is reciprocated in the direction of the arrow 13 by a cam 29. As the casing 22 and feeler pins are moved against the end of the cigarette to be tested, in timed relationship to the step by step motion of the drum 4, movement of the feeler pins is resisted by the end of an unacceptable cigarette, the springs 26 are fixed and a plate 28 obstructs the light path of a photo-electric device, e.g. 30, 32. If the cigarette end is faulty the spring 26 is not flexed, the device as 30, 32 is not obstructed, and a rejection pulse is passed to an operating magnet 44 which, after a suitable time delay, operates a pneumatic valve 46 controlling the nozzle 48. The delay is four cycles in the case of the device 14 and two cycles in the case of the device 38. The drum 4 is mounted on a shaft 2 driven by a motor 140 which also drives the shaft 21 of the cam 29 and the shaft of the corresponding cam 20 for the device 38. The motor 140 also operates a cyclic signal source 141 which feeds pulses to a signal storage device 42. The device 42 includes "AND" gates which pass a rejection pulse to the magnet 44 only when a pulse is received from the source 141 (i.e. during testing only) and also from an unobstructed photo-electric device as 30, 32. The storage device 42 may include circuits for counting the number of cigarettes with faults in each particular segment, the total number of cigarettes tested, the number of acceptable cigarettes, and the number with faults in one, two, three or all segments respectively. Instead of being mounted on springs the feeler pins may be mounted for longitudinal movement within the core of a solenoid. In this case, Figs. 7 and 8 (not shown), the pins actuate contacts instead of photo-electric devices. In a further embodiment, Figs. 9 and 10 (not shown), the feeler consists of an insulated body having a number of electrodes therein which form individual measuring capacitors with the drum 4 and with a further drum, between which the cigarettes are held during testing, the drums forming the counter electrode.

Title: Improvements in or relating to reciprocating piston engines
IPC: F02B75/28
Filed: 1965-05-12
Abstract: 1,111,672. Revolving cylinder engines. CONSERVATOIRE NATIONAL DES ARTS ET METIERS and H. GIRERD. May 12, 1965 [May 15, 1964], No. 19946/65. Headings F1A, F1B and F1M. In an engine with a piston and cylinder rotating in a stationary casing 3, the lower part of the piston is formed as a cam curve which acts upon stationary rollers 4 to produce rotation of the piston as it reciprocates a projection 9 on the piston engaging a groove 10 of the cylinder to cause the cylinder to rotate. A gear wheel 20 on the cylinder rotates the output shaft through gear wheel 21. The engine may be an I-C. engine or one driven by air, steam or hydraulic fluid. In an apposed piston I-C. engine, Fig. 2 ports in the cylinder control admission of air to a compression space 30 below the piston, transfer of the charge to the combustion chamber 14 between the pistons, and exhaust ports which are inclined so that the escaping exhaust produces a force on the piston assisting its rotation. The space 24 between the piston and a stationary plunger 6 may form a compressor space with inlet and outlet passages 23a, 23b controlled by ports 25 in the cylinder 2. Diaphragm pumps 26a, 26b for lubricating oil and fuel are actuated by the pressure in the passages 23a, 23b. In a modification Fig. 4 (not shown), separate combustion chambers 14a, 14b, are formed at the remote ends of the pistons 1 and cooling fluid is drawn through passages 36 in the cylinder by centrifugal forces. In a double-acting engine Fig. 5 (not shown) a combustion chamber 14 is provided between the opposed pistons 1 along with separate combustion chambers 14a at their opposite ends. In an engine with a hydraulic power take-off, Fig. 6, the piston and cylinder 1, 2, have enlarged portions 81, 60, forming a charge pump space 80, the wall 67 forming a rotary valve controlling inlet and outlet ports 98, 95. The charge is drawn into the pump through passages 85 running through the cylinder based cooling fins. A cam member 57 on the piston engages rollers 52 on these radial shafts 49. . 51, Fig. 7, to produce rotation and reciprocation of the piston, the member 57 having a hexagonal cross-section sliding in a similar recess in an extension 59 of cylinder 2 so that the cylinder rotates with the piston. The member 59 is geared to gear wheels 53 on the shafts 49.. 51. The piston 1 actuates the plunger 114 of a hydraulic pump which receives liquid through port 128 and passage 122 and delivers it through passage 123 and port 132 to a hydraulic motor. The delivery of the hydraulic pump is controlled by adjustment of a sliding cylinder 113 which is controlled manually or automatically in dependence upon the pump delivery pressure. Fuel and lubricating oil are delivered by plungers 141, Fig. 7 in the shafts 50, 51, actuated by the fluctuating pressure in the hydraulic circuit 148.
