Filed: 1971-05-05
Abstract: 1348064 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 5 May 1971 [6 May 1970] 13174/71 Heading A3B A toe lasting machine includes a heel rest 2 which is moved into engagement with the heel end of the last 1 and, at a later stage in the machine cycle, is moved forwardly by a predetermined increment to compensate for any pressing back of the shoe, under the thrust of the wipers 9, 10, that is likely to result from compressability of the materials at the back end of the shoe or any flexing of parts associated with the heel rest mounting. As described the heel rest 2 is incorporated in a lasting machine of the type in which the wipers 9, 10 are temporarily arrested at a time when the wipers 9, 10 just cross the edge of the insole, the heel rest 2 being given its incremental movement when the wipers 9, 10 are temporarily arrested. The heel rest 2 is carried by a piston 3, movable in cylinder 4, and is moved into engagement with the heel end of the last 1 by oil under relatively low pressure which is supplied via line 6, metering device 19, line 17, valve V, line 20, non-return valve 22, low pressure regulator 21 and valve W from supply line D. When the wipers 9, 10 are temporarily arrested a cam 14 on the wiper operating piston rod 13 operates a switch 15 which causes oil under high pressure to be supplied from line D, through valve W and line 18 to the space below piston 23 in the metering device 19. The piston 23 moves upwardly until it contacts stop screw 26, thus expelling oil from the cylinder 30 of the metering device 19. This oil gives the heel rest 2 its increment movement, the non-return valve 22 preventing flow of oil in the opposite direction. The stop screw 26 allows the movement of the piston 23, and thus the incremental movement of the heel rest 2, to be adjusted.

Abstract: 405,665. Centrifugal blowers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) May 7, 1932, No. 13231. [Class 110 (i).] An electric regulating system for controlling pressure in a blower installation, comprises a responsive element e.g. a diaphragm a, controlling a movable contact b operating between contacts d, c on a carrier e in the form of a nut longitudinally displaceable on a spindle f which is rotatable through differential gearing g, by one or other of two motors h, i. The contacts b, c, d control the operation of relays o, n to energize the means P controlling the pressure, e.g. a blower motor, in the appropriate direction, and at the same time control the energization of the reversible motors h, i. Assuming the pressure to be too high, diaphragm a causes closure of contacts b, d, energizes relay o which controls the device P to reduce the pressure. At the same time the motor h is energized and moves the carrier e so as to open the contacts d, b. Before this occurs one contact m of two additional contacts k, m on the carrier, contacts with a central piece q and prepares the circuit for the retracting motor i which is closed when the relay o drops out due to opening of contacts b, d. The carrier is now moved to close contacts b, d once more and open contacts q, m. The action is repeated with gradually diminishing movement of the carrier e until the variable is returned to the desired value. The action is the same when the pressure drops below the desired value, contacts b, c, q and k being then operative and motors hand i being rotated in the reverse direction. The speed imparted to the carrier e by the motor h is higher than that imparted by the motor i in the ratio of 10 : 1.
