Abstract: 681,580. Recovering tobacco from cigarettes. MOLINS MACHINE CO., Ltd. July 10, 1951 [July 10, 1950], No. 17259/50. Class 130. A cigarette stripper i.e. a device for recovering tobacco from defective cigarettes, comprises a spiked member movable to impale the cigarettes thereon and to carry the impaled cigarette between jaws which cause the paper to burst. The device is particularly applicable to mouthpiece cigarettes which are inserted through a funnel 8 and rest against a pair of rubber-covered jaws 10 in the path of spiked arms 5 on a rotatable shaft 4. The spikes pierce the paper of the cigarette, preferably passing right through the cigarette, and when the cigarette is forced between the jaws 10, the paper bursts along the line of perforations formed by the spikes. Brushes 15 remove all the tobacco from the burst paper, the mouthpiece of a cigarette remaining impaled on the spikes along with the cigarette paper until they are brushed off the spikes by a pair of brushes 16 into a space 21 from which they are removed by suction through a duct 22. A second suction device 18 removes tobacco dust. The arms 5 rotate between semi-circular plates 11, 12 spaced apart a distance equal to the diameter of a cigarette, and cover-strips 13, 14, preferably of transparent material are fixed to the edges so that the interior space is enclosed.

Title: Improvements in or relating to flow proportioning means
IPC: F23N1/02
Filed: 1935-06-18
Abstract: 454,982. Distant - control systems. REINEKE, J. H., 26, Castroperstrasse, Bochum, Germany. June 18, 1935, No. 17492. [Class 40 (i)] [See also Group XXIX] A flow-proportioning apparatus for use in connection with gaseous mixture (e.g. a mixture of coke oven gas with blast furnace gas) is arranged so that the quantity of a third gas (e.g. air) is made dependent on the quantity and proportions of the gaseous mixture. The Figure shows a fluid pressure servomotor system for effecting this control. The conduits 5, 6 conveying the constituents of the mixture are each provided with an orifice plate 8, the pressures on each side of which are arranged to act on the opposite sides -of a pair of diaphragms 12, 13 coupled together by a lever 21 pivoted on a movable fulcrum 24. The lever 21 is coupled by a link 25, lever 26 and spring 28 to an auxiliary valve 20 controlling doubleacting piston 31 coupled by a flexible link 32 to a slidable member 33 carrying the fulcrum 24. The arrangement is such that any unbalance of the pressures on the diaphragms occasioned by variation of the flow in either of the conduits 5, 6 causes the piston 31 to operate in the direction to adjust the fulcrum to restore the balance. The piston 31 also acts through a flexible link, pulley 61 and cam 59 to adjust the fulcrum 55 of a similar servomotor device controlled by the flows in the conduits 2, 3 conveying the gaseous mixture and air supply respectively, whereby the piston of this servomotor system adjusts the position of a throttle valve 52 in the air supply conduit both in accordance with the total flow of the mixture and the flows of the individual constituents. In a modification, the diaphragms 12, 13 are replaced by a pair of manometer U-tubes fitted with resistance devices comprising a series of contact rods of different lengths contacting with mercury in the tubes. These resistances are connected in circuit with a Kelvin balance or other balancing device or relay, a variable resistance operated by the piston 31 being included in the circuit to restore the balance when the flows in either of the two conduits 5, 6 vary. In a modification of this form a reversible electric motor coupled to a pinion, rack and flexible link by the pulley 61 replaces the piston 31. Specification 440,342, [Group XXIX], is referred to.

Title: Waterless-in-use skin cleaner and process for producing the same
IPC: A61K8/31
Filed: 1956-06-11
Abstract: A skin cleaning composition for use without addition of water comprises (a) an organic solvent for skin contaminants, suitably a mineral oil of cosmetic grade, (b) a non-ionic surface active agent which is preferably a condensate of 2-20 mols of ethylene oxide with 1 mol of a fatty acid having 12-22 carbon atoms in the alkyl chain, (c) a synthetic hydrophilic acid polymer colloid thickening agent other than a cellulose derivative and (d) water, the composition having a pH of 5-7. (c) is suitably a copolymer of about 99% by weight of acrylic acid or a homologue thereof and about 1% of a polyallyl sucrose in which the sucrose molecule has 5-6 allyl groups. Sodium hydroxide is generally added to the composition to neutralize the acidity of this constituent.  The composition is produced in a creamy form by dissolving the surface active agent in the solvent and the colloid in the water and mixing the solutions.  The breaking qualities of the composition are improved by incorporating small quantities (up to 2%) of tertiary amines having one alkyl group and two polyoxyethylene groups attached to the amino nitrogen atom. Corrosion inhibitors such as oleoyl sarcosine and 2-hydroxypropylamine nitrite, and anti-evaporants such as propylene or diethylene glycol are also desirably incorporated.

Title: Improvements in or relating to automatic control systems
IPC: G05D23/275
Filed: 1944-09-20
Abstract: 587,369. Automatic Control systems. ELECTROFLO METERS CO., Ltd., and SMITHSON, A. Sept. 20, 1944, No. 17948. [Class 38 (iv)] [Also in Group XXIX] Temperature &c.-In a system for automatically controlling a variable, the position of a pointer, which is dependent on the variable, is periodically detected, the detecting means controlling a pair of switches which, in turn, control two electrically operable devices, such' as electric motors or electromagnets, one of which effects the permissible displacement of a valve regulating the variable while the other controls the extent of such displacement. In a system for automatically correcting the temperature of a furnace to lie between predetermined limits, Fig. 1, temperature-responsive relay means of the type described in Specification 363,548, [Group XXXVIII], control changeover switches 1 and 2. When the temperature is below the lower limit (A, Fig. 2), switch 2 energizes an electromagnet 5 from a D.C. source to open a valve 6 controlling the fuel and /or air supply to the furnace. The extent to which valve 6 is opened is dependent on the position of a stop 4. So long as the temperature is below the lower limit, 'switch 1 energizes a reversible motor 3 from the D.C. source to run in such a direction that stop 4 is moved to permit a gradual increase in the opening of valve 6, thus increasing temperature. When the temperature is between the limits (B, Fig. 2), motor 3 is de-energized, stop 4 is stationary, and valve 6 is held open by electromagnet 5, energized through switch 2, to an extent dependent on the position of stop 4. When the temperature is above the upper limit (C, Fig. 2), electromagnet 5 is de-energized and valve 6 closes, thus reducing temperature. So long as the temperature is above the upper limit, motor 3 is energized, through switch 2, to run in such a direction that stop 4 is moved gradually towards the closed position of valve 6. Limit switches of normal type may limit travel of motor 3 in either direction. Specification 318,308, [Class 38 (iv)], also is referred to.
