Abstract: 1326408 Travelling ends down detector PARKS-CRAMER CO 13 Oct 1970 [14 Oct 1969] 48684/70 Heading D1F An ends down detector is combined with a travelling unit such as a pneumatic cleaner and comprises a detector to sense the presence of ends during a traverse of, e.g. a spinning frame and a transmitter to communicate such information. The transmitter may comprise electric lamps (23, 23') Fig. 2 (not shown) corresponding respectively to two sides of the spinning frame. Information from the transmitter is received by the stationary circuit of Fig. 4 comprising photosensitive elements 30, one at each end of a spinning frame, which energise a relay coil 32. The coil 32 closes contacts 34 and 35 which respectively latch in the relay and illuminate signal lamps 38 and 39 at opposite ends of the spinning frame respectively. A motor 40 is wired in parallel with lamps 38 and 39 to drive a cam 41 which after a suitable time interval initiates flashing of the lamps by means of a flasher relay coil 44. The circuit is reset by means of a switch 28 which breaks the circuit to relay coil 32 and thus releases the latching contact 34. Specfications 1,326,409 and 1,323,430 are referred to.

Abstract: 1319673 Suspension levelling systems REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 19 Oct 1970 [24 Oct 1969 27 May 1970] 49602/70 Heading B7D A vehicle suspension levelling system comprises hydraulic rams 9, 10 which adjustably anchor torsion bar springs 3, 4 connected to trailing rear suspension arms 5, 6 and are supplied with hydraulic fluid or discharged by an electrically-driven pump 11 or an electromagnetic valve respectively energized through a time delay device 24 from a height sensing switch 19 actuated by a contact 20 on an antiroll bar 21, the rams 9, 10 communicating with the pump 11 and valve 13 through a distributer 16 including valve means responsive to the differential state of the rams. The distributer 16 comprises a fixed body 25 and respective relatively-rotatable distribution members 30, 31 connected to the rams 9, 10 through linkages 28, 26, 27. The distribution members 30, 31 are formed at two zones 32, 33 with channels 36, 37 and 50, 51, 52, 53, 54, 55 which, in conjunction with one-way valves 42, 43, 44, 45, co-operate to ensure that both rams 9, 10 are contracted or extended by the same amount in response to closing of the switch 19 even if the vehicle is unsymmetrically loaded so that the pressures in the rams are unequal.

Title: Improvements in or relating to Colour Television Receivers
IPC: H04N9/44
Filed: 1966-11-08
Abstract: 1,168,248. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 8 Nov., 1966 [8 Nov., 1965], No. 49870/66. Heading H4F. The invention relates to the synchronization in a receiver of a switch, such as the switch which is used in the " PAL " and " SECAM " (Registered Trade Mark) systems, which is required to change state in alternate lines in response to " bursts " of oscillation of subcarrier frequency which are transmitted at the beginning of each line and comprise two components, one of constant phase in all lines and the other of a quadrature phase which is reversed (i.e. changed through 180 degrees) in alternate lines. The invention makes use of the characteristic frequency spectrum of such " burst " signals which are formed of a main component at sub-carrier frequency together with upper and lower side-band components spaced from the main component at intervals of one-half line frequency. In general a signal at half line frequency suitable for controlling the switch change of state may be derived from any two adjacent frequency components in the signal spectrum. In one arrangement, Figs: 2 and 3 (not shown), narrow bandwidth quartz filters select and separate the main component at sub-carrier frequency and the first upper or lower side-band component. These two components are then combined in a mixing circuit (a synchronous demodulator) to obtain the difference signal at half-line frequency. The switch may be synchronized by local line frequency pulses and established in correct phase by the half-line frequency signal. If desired, the separated component at sub-carrier frequency may be used directly as a datum carrier of constant phase for colour demodulation or indirectly to synchronize a datum carrier oscillator. In a second arrangement (not illustrated by drawings) a single filter of suitable bandwidth may select both the main and sideband components. These are passed to a non-linear circuit which generates signals which include the desired signal at half-line frequency. In a third arrangement (not illustrated by drawings) a filter selects the main component and both upper and lower first side-band components. The combination is then applied to an amplitude detector to produce a signal at half-line frequency.
