Title: Improvements in or relating to sound reproducing apparatus
Inventor: DRAPER ALBERT ERIC
IPC: G11B3/08
Filed: 1966-04-19
Abstract: 1,133,953. Automatic record changers. S. KOROBUK Ltd. 18 May, 1967 [19 April, 1966], No. 44227/65. Heading G5R. Trigger 43, Fig. 1, is depressed by the edge of a 10-inch record, thus permitting compression spring 63 to swing lever 40 counterclockwise until lug 46 reaches stop 53, at which stage the record has passed beyond trigger 43. Link 62 has been forced downwards by spring 63 during this movement, in consequence of which bellcrank lever 57 is rotated counterclockwise about its pivot 58; arm 59 of the bell-crank lever 57 pushes against a stop arm 34, Figs. 1 and 2, to rotate it about its pivot 56, Figs. 1 and 2, in a counterclockwise direction as viewed in Fig. 2. This movement of stop arm 34 places a stop surface 35, Fig. 2, in the path of a pin 37, the pin 37 forming part of a pin-and-slot connection between an arm 23 and an arm 26; the arms 23 and 26 form part of a known mechanism for swinging a pick-up arm 14 outwards and then inwards during lowering of a record- (not shown) from a stack (not shown). The placing of stop surface 35, referred to above, ensures that a pin 29, Figs. 1 and 2, extending downwards from the pick-up arm 14, will enter an appropriate one of three grooves 28 in a quadrant 27 secured to the arm 26, during the part of the cycle before the pick-up 13 is lowered on to the record, thus positioning pick-up 13 correctly for the edge of a 10-inch record during completion of the cycle. With a 12-inch record, trigger 43 is depressed, and contact between the record and the trigger is maintained until lug 46 rides beyond stop 53, permitting further counterclockwise rotation than before of bell-crank lever 57 and of stop arm 34, thus placing stop surface 36, Fig. 2, in the path of pin 37. Pin 29 thus enters a different one of the grooves 28. With a 7-inch record, trigger 43 is not contacted, so that bell-crank lever 57 is not moved, and in consequence stop arm 34 remains clear of pin 37, and pin 29 can enter a third one of the grooves 28.

Title: Data communication system

Abstract: 1482860 Data communication system; master and slave systems INTERNATIONAL BUSINESS MACHINES CORP 30 Oct 1975 [16 Jan 1975] 44803/75 Heading H4P [Also in Division G4] A data communication system comprises a central station 10 connected by communication channels 11, 15 to interface units 12 each connected to the first T 1  and last T n  of a series of remote terminals 14. The system normally operates in a receive mode, when data is transmitted from station 10 through selected inter faces to terminals 14. Station 10 may also initiate a transmit mode by addressing a selected interface to cause the associated terminals to return data; this mode may be terminated by the central station (Fig. 2) or by a decoder 32, Fig. 2a (not shown), in the interface which detects the end of a transmission. Each interface (Fig. 2) comprises a modem 20, 21. Incoming signals 11 are fed to a register 22 and decoder 23; a transmit mode signal Li and a receive mode signal RESET respectively set and reset a latch 24 whose outputs control gates 26 and 27. In the receive mode, data is passed through gate 26 to the first terminal T 1 ; it passes through each of the terminals and out of terminal T n  but is then blocked by gate 27. In the transmit mode, latch 24 is set, removing one input to gate 25 and applying a RTS signal to modulator 21. When modulator-demodulator synchronism with the central station has been achieved, a CTS signal from modulator 21 removes the second input from gate 25 (thus blocking gate 26) and enables gate 29, whose output enables gates 27 and 30. Gate 30 connects a pattern generator 31 to the series of terminals 14, as in Specification 1,250,352 or U.S.A. Specification 752,932, data being transmitted to station 10 via the enabled gate 27. A modification is described with reference to Fig. 2b (not shown) for use when there is no CTS signal or when there is a fixed time period for modulator 21 to become active.

Abstract: 1517667 Expanding wheel gear VAN DOORNES TRANSMISSIE BV 3 Nov 1976 [6 Nov 1975] 45732/76 Heading F2D In a V-belt pulley in which the axial spacing of the coned flanges 1, 4 is varied by supplying at 10 hydraulic pressure to a space 8 of a cylinder 7 integral with the axially movable flange 4, and centrifugal pressure on the liquid is compensated by centrifugal pressure of liquid fed from the working space 8 to a space 12 on the opposite side of a piston 9 fixed to the shaft 2 of the other flange 1, the liquid is supplied to the compensating space 17 from 8 through a passage which can be completely or partly closed in response to spacing between the flanges, speed, or differential pressure. In Fig. 1 a rod 16, moving axially with the cylinder 7 and sliding through a bore in the piston 9, has a liquid supply passage 17 which feeds the compensating space 12 until the flanges 1, 4 approach sufficiently for the piston 9 gradually or suddenly to cover the end of the passage 17 and thereby cut off any further flow. Since the compensating space 12 is open to atmosphere at a gap 14, where the liquid could escape, the cutoff of flow under this large diameter and hence low speed condition reduces the flow requirement and hence the capacity required of the supply pump. In Fig. 2, not shown, the piston 9 similarly controls a groove (18) in the cylinder wall. In Fig. 3, not shown, the boss 15 of the piston 9 carries a radially inwardly spring-loaded ball valve (19) which is unseated by centrifugal force to supply liquid to the compensating space at higher speeds. In Fig. 4, not shown, there is a rod 16 similar to that of Fig. 1, but its passage contains a spring-loaded valve opened by differential pressure between the working and compensating spaces, the delivery opening being also subject to being covered by the piston 9 as in Fig. 1.
