Patent GB-789854-A (GB)
Abstract: 789,854. Calculating-apparatus. AKTIEBOLAGET ATVIDABERG-FACIT. March 15, 1956 [March 19, 1955], No. 8093/56. Class 106 (1). In a machine adapted to perform division by repeated subtraction automatically, and wherein subtraction is effected by complementary addition, denominational shift of the actuator occurs when the highest order transfer latch is or is not tripped according to whether addition or subtraction is in progress. The invention is applied to a machine with a rotatable cam disc and pin wheel actuator, e.g. as described in Specification 724,043 and wherein the complement of a divisor and its true value alternately are added to the totalizer in successive denominational positions of the actuator. The invention is, however, also applicable to machines with reciprocating actuators. Slidably keyed to the actuator shaft 1 is a collar 2 provided with a finger 2a adapted to rock a lever 3 to initiate denominational shift of the actuator. A spring 14 maintains the collar normally, at the commencement of each cycle (see Fig. 3), with the finger clear of the lever. A bifurcated lever arm 5 is adapted to be rocked downwardly and into the path of an ear 2b on the collar 2 when the transfer latch of the higher totalizer order is tripped. Similarly a lever 7 is rocked into the path of the ear when the actuator is adjusted for subtraction. During a series of add cycles, the lever 7 is ineffective and the lever 5 remains ineffective until the concluding cycle; the axial position of the collar therefore remains unchanged and the finger 2a does not trip the lever 3. During the concluding add cycle, lever 5 rocks downwardly and cams the ear 2b and collar 2 to the left, the ear 2b passing between the bifurcations of the lever 5. In this position of the collar 2, the finger 2a trips the lever 3 to initiate denominational shift of the actuator. During subtract cycles the lever 7 remains lowered throughout the series and the lever 5 is lowered at each cycle except for the concluding cycle. During these cycles, the ear 2b is cammed leftward by a projection 7a on the lever 7 and then further leftward by the left-hand bifurcation of the lever 5. The finger 2a is, in consequence, carried to the left of the lever 3 and does not actuate the lever. During the concluding cycle, however, the lever 5 is not lowered, the ear 2b is cammed leftward only by the lever 7 and the finger 2a is positioned to trip the lever 3 to terminate the series.

Title: Filter Silencer for Compressed Gas Stream
IPC: B01D46/24
Filed: 1979-10-15
Abstract: A filter silencer for oil contaminated compressed air is constructed to enable extremely high efficiencies to be obtained both in regard to filtering and silencing. The oil contaminated air passes through a tube 39 to the centre of a coalescing filter element 29 surrounded by an open pore drainage barrier 36 of foamed material. The element 29 having an oil-removal efficiency of at least 99.95% traps solid particles and coalesced oil drips from the barrier 36 to the bottom of a casing 44. The cleaned air passes through an intervening space to the inside of a cylindrical silencing element 32 through which the air is discharged to atmosphere. The elements 29, 32 may be made of borosilicate glass fibres bound by a synthetic resin. The air leaves tube 39 through ports 47 located for the air to undergo a change of direction throwing out some oil droplets. The silencing element may alternatively be located coaxially above the filter element with an intervening space. Where maximum silencing efficiency is not required the silencing element may be omitted so that the air after travelling across the intervening space escapes through large vents at the top of a lateral wall of a casing. <IMAGE>
