Title: Method and apparatus for removal of tips from scrap cigarettes
Inventor: DEARSLEY GEORGE
IPC: A24C5/36
Filed: 1962-05-11
Abstract: 1,003,000. Removing filter tips from defective cigarettes. AMERICAN MACHINE & FOUNDRY CO. May 11, 1962, No. 18316/62. Heading A2C. A method of removing filter tips from cigarettes includes aligning and gripping the cigarettes in side by side relationship with their tipped ends facing in one and the same direction, transversely moving the gripped aligned cigarettes and changing the motion of the filter tip in a direction parallel to the direction of said cigarettes. Tipped cigarettes in trays stacked on a platform 2 are pushed into a hopper 4 from which they flow downwardly past driven rollers 12, 14 into a converging channel 11 formed by two endless belts 24, 26, each running at the same speed and in the direction shown by the arrows (Fig. 1), which progressively grip the cigarettes. A rotating paddle-like member 40 engages and knocks the tips off the cigarettes. The tips then pass down a shoot 30 into a rotating sieve 32 which removes any remaining tobacco particles. The de-tipped cigarettes 37 pass to a conveyer 38. The rollers 12 may be replaced by fixed guide plates. In another embodiment (Fig. 3, not shown) the tips are removed by a rotating knife.

Title: Improvements in and relating to guard arrangements for power presses
IPC: F16D11/06
Filed: 1946-06-19
Abstract: 613,381. Machinery guards; actuating clutches. RHODES, C. J. June 19, 1946, No. 18476.. [Classes 80 (ii) and 80 (iv)] In a power press having a clutch-controlling member and an interacting latching member movable by a guard into and out of a locking position, a spring link is provided, connecting the latching member to the clutch controlling member, the said spring link being adapted to be stressed by movement of the latching member out of the locking position, and thereby resiliently to urge the clutch controlling member into the engaged position. As shown, a guard is connected through links 22 to a member 16 pivoted at 17, and carrying a roller 19 engaging a recess 20 in a cam 21 on the driven shaft 1. The member 16 is connected through a spring link 15 and a link 9 to a latch member 11 engaging a lug 8 on the clutch control member 5. The latter is pivoted at 6, and has an extepsion 7 abutting a seating 18 on the member 16, and engaging a lever 4 of a clutch key 3 to keep the clutch disengaged whilst the guard is open. On closing the guard the control member 16 is rotated, the roller 19 is withdrawn from the recess 20, and the seating 18 from the stop 7. The member 5 is rotated rapidly through the spring 15, link 9, latch member 11 and lug 8, removing the stop 7 from the lever 4 of the rolling key 3, to engage the clutch. As the shaft 1 rotates, a roller 23 on a disc 2 engages the toe of the latch member 11, to disengage it from the lug 8. The member 5 then rotates under the action of a spring 13, and the stop 7 thereon is repositioned to abut the lever 4 and disengage the clutch. The guard can then be opened to bring the parts back into their initial positions. The invention is applicable to other types of clutch mechanism by interposing a spring link under compression between a latching member and the clutch controlling means.

Title: Process for basic sulfurized metal phenates
IPC: C10M159/24
Filed: 1963-05-09
Abstract: A lubricating oil containing a basic carbonated sulphurized alkaline earth metal alkyl phenate is made by blending together in a lubricating oil medium an alkyl phenol, a metal sulphonate and a monohydric alcohol having from 8 to 18 carbon atoms, there being used for each molal quantity of the alkyl phenol from 0.01 to 1 mole of the sulphonate and from 0.1 to 1.5 mole of the monohydric alcohol, heating the resulting blend, adding sulphur and an alkaline earth metal hydroxide or oxide in an amount sufficient to give a base ratio of 1.2 to 4.5, the sulphur being added in an amount such that the mole ratio of sulphur to alkaline earth metal oxide or hydroxide is from 0.25 to 4.0 again heating then adding ethylene glycol, removing water of reaction from the mixture, cooling, then treating the mixture with from 300 to 10 mole per cent of carbon dioxide based on the alkyl phenol and thereafter heating the mixture at reduced pressure to remove ethylene glycol and water, and if desired at least part of the monohydric alcohol, to obtain the desired lubricating oil composition. The alkyl phenols are represented by the formula (R)aAOH wherein A is an aromatic radical, preferably benzene, R is a straight or branched chain, saturated or unsaturated essentially hydrocarbon radical having 4 to 30 carbon atoms and a is a number having a value from 1 to 2.  The total number of carbon atoms for the R radicals has a minimum value of 8.  The basic sulphonates contain from 0% to 300% of metal in excess of the metal of normal sulphonates and are obtained by the addition of excess base to neutral sulphonates of the formula [(R)aASO3]2M where R is a straight or branch-chain saturated or unsaturated essentially hydrocarbon radical having a molecular weight of 150 to 800, A is an aromatic radical, such as benzene, naphthalene or anthracene, a is a number having the value of 1 to 4 and M is an alkaline earth metal.  The lubricating oil may be a petroleum lubricating oil, alkylene polymer, alkylene oxide type polymer, carboxylic acid ester, alkyl benzene, polyphenyl or silicon polymer.

Title: Improvements in electric switches
IPC: H01H33/70
Filed: 1935-06-28
Abstract: 466,588. Gas-blast switches. MARX, E. June 28, 1935, No. 18546. Void. Convention date, June 29, 1934. [Class 38 (v)] The Specification, which does not admit of satisfactory abridgment, discloses a gas-blast switch in which the ratio of the pressure of gas before traversal of the arc-space to the external atmospheric pressure is less than the critical value but exceeds the pressure required to produce an effective flow. The maximum pressure-drop occurs in the arc-space and the drops in the inlet and outlet ducts are only fractions of the total. Preferably a fan is employed operating to produce a blast-pressure less than 100 cms. of water, of which only a few centimeters are absorbed in the inlet and outlet ducts. The fan may be driven by an electric motor and may be started shortly before, or at, the contact-separation, and stopped again when the arc is quenched. Alternatively, ventilating fans may be employed for quenching, and the delivery duct normally closed, or deflectors may be arranged in the delivery duct to offer resistance to the flow, this resistance being removed by movement of the contacts. Fans may be started by overload relays, the overload itself performing this function when the relays operate with a time-lag. With a manual switch, the fan-energy may be derived from the manual operation, with a spring for imparting rapid acceleration.
