Abstract: 686,662. Hydraulic shock-absorbers. BOURCIER DE CARBON DE PREVINQUIERES, C. M. L. L. April 27, 1948 [May 31, 1947; July 2, 1947; Jan. 21, 1948; March 10, 1948], Nos. 11481/48, 11482/48, 11483/48 and 11484/48. Class 108 (iii). A direct - acting hydraulic shock - absorber comprises a piston spaced from the cylinder wall so that liquid flows between the outer surface of the piston and the cylinder wall in the form of a thin film the piston having means co-operating with the cylinder wall to centre it in the cylinder. The piston shown in Fig. 3 comprises a series of rigid or resilient washers 10 of less diameter than the cylinder bore, clamped on the piston rod between a pair of end plates 13 which are apertured at 14. The washers 10 may be radially slotted and may (as shown), or may not, Fig. o (not shown), be provided with spacers 12. The washers 10 may be replaced by a solid cylindrical portion occupying about the same axial length and of less diameter than the cylinder bore in order to provide a peripheral liquid-damping clearance. The central portion of reduced diameter may be of material which has a different thermal expansion coefficient from that of the cylinder in order to compensate for changes in viscosity due to temperature changes. The piston may be provided with two axial passages containing respective spring-loaded ball valves 6, 7 (Fig. 9), which relieve excess pressure on either side of the piston. The end plates may each be formed with an abutment of part-cylindrical profile. In the constructions shown in Fig. 9, the cylinder space above the piston includes a chamber 21 separated from the remainder of the space by a head 27. Flow into the space 21 is controlled by a spring-loaded ball valve 22, and flow in the reverse direction by a flap valve 25. Specification 686,723 is referred to. In the Specification as open to inspection under Sect. 91, the valve 25 of Fig. 9 may be rigid with the head 27 which has segmental portions removed which allow flexing of the valve. The bellows 29 may be replaced by a tubular dust shield rigid and concentric with the piston rod 1 and having drain holes at its bottom. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to colour television reception
Inventor: TINGEY PETER ALBERT
IPC: H04N9/465
Filed: 1966-03-17
Abstract: 1,107,548. Colour television. BRITISH BROADCASTING CORPORATION. 8 Feb., 1967 [17 March, 1966], No. 11816/66. Heading H4F. The Specification describes a circuit for decoding the colour burst signals in a received signal of the PAL type, wherein the colour burst signal undergoes a 90 degrees phase change on alternate lines. The colour burst signals are separated from the video by a filter 10 and are applied to one input of a synchronous detector 11 and to a one line period 64 Ás delay 12. If the colour burst signal from the nth line is E cos wt, that from the next (n + 1)th line is E cos (wt + #/2) and so on. The outputs of the delay for corresponding lines are E cos (wt + #/2) and E cos wt. A 90 degrees phase shifter converts these output signals to E cos (wt + #) and E cos (wt + #/2) &c. which converted signals are applied, via a gate 14, opened during the line blanking periods, to the other input of synchronous detector 11. Thus, for odd lines, the two inputs to the detector are in antiphase, and for even lines, are in phase. The output 17 of the detector thus has a polarity indicating the phase of the colour burst signal, and can be used for synchronizing &c. purposes.

Abstract: 1,199,355. Capping bottles &c. BROWN, BOVERI & CIE A.G. 12 March, 1968 [18 March, 1967], No. 12043/68. Heading B8T. [Also in Division B3] A crown cap blank is simultaneously stamped out of a metal band and pressed on the neck of a bottle or container by the influence of a rapidly varying magnetic field produced by a short electrical impulse. The upper end of a container 3 is introduced into a hole in a stamping die 1 profiled so that sufficient metal is stamped out to engage with a bead on the container. Above the die 1 is a coil 2 and between them a continuous band 4 of metal providing the material for the cap. When a short-time current pulse is generated in the coil by an impulse generator (not shown) through supply lines 5, 6, a blank is stamped out of the band and forced on the neck to seal the container. The band 4 is moved stepwise. At this time a sensor transmits an impulse to a delay element which feeds the impulse generator only when the next container is in position for sealing. A sealing liner may be applied to the underside of the band, or a separate continuous sealing strip may be interposed between the container and metal band. The mouth of the container may be of rectangular crosssection.

Filed: 1930-04-16
Abstract: 353,065. Coin-freed article delivery apparatus. MERIVALE, V., Middleton Hall, Leeds. April 16, 1930, No. 12091. [Class 27.] Articles stored in separate compartments; coinaction, mechanicalconnection and multiple-coin. - An apparatus for the alternative hire or purchase of an article, such as a book, comprises a container 1, Fig. 2, having an upper compartment for a book 2 which rests upright on a hinged false bottom 3, and a lower closed compartment 4 containing the actuating mechanism. The container is closed by a flap 6 which overlaps the compartment 4 and has four tubular members 15 passing through slots into the compartment 4 where they are engaged by spring catches 16 to lock the flap 6 in closing position. The catches are pivoted members biassed by spring plungers 19 adjustable by screws 20. To release the flap, a shilling and three pennies are inserted through slots 12, one into each member 15, and a cover 21, which is hinged to the flap at 39, is then closed so that projections 22 on the cover press on the coin and cause these to lift the catches out of notches 17 in the members 15. The flap 6 then opens under the action of blade springs. When the book is taken out, the false bottom 3, which may be in several sections, rises under the action of a spring 11 to foul a bar 10 and prevent the flap from being closed unless the book is replaced. The three pennies, representing the hire of the book, fall to the bottom of the compartment 4, and the shilling, representing the purchase price, falls to a member 28, Fig. 4, rotatable in a guide 27 and provided with ribs 29 one of which has an end 30 to retain the coin. Returning coin.-If the book is replaced, the member 28 is rotated to deliver the coin to a return tray 24 by a bifurcated pin 33 on the flap 6 rocking a member 31, Fig. 5, which is influenced by a spring 32 to hold the member 28 in coinretaining position. Fraud preventing.-To prevent its fraudulent actuation by a pin or knife, the edge 34 of the member 31 is bevelled and a guard strip 35 is mounted in line with the vertex of the bevel. Also the flap 6 is prevented from opening unless the cover 21 lies flush with it, to prevent unlocking of the catches by a knife. For this purpose, the hinge pin of the cover is flattened at 40, Fig. 6, and can enter or leave a slot 41 in a projection 38 of the container, that extends through the flap 6, only when the cover is flush with the flap. Registering.-The pin 33 on the flap operates a counter through ratchet mechanism 37.

Abstract: 952,332. Photographic cameras. KAMERAUND KINOWERKE DRESDEN VEB. April 6, 1960, No. 12211/60. Heading G2A. In a photographic camera including an exposure factor setting ring rotatable over a first region for daylight exposures and over a second region for flashlight exposures and coupled to an adjustable diaphragm and a shutter speed setting mechanism so as to control them simultaneously in accordance with a predetermined programme, and wherein the setting ring is coupled to a follow-up pointer for the needle of an exposure meter visible in a window, when the camera is set for flashlight exposures by rotating the ring into said second region a switch disconnects the exposure meter to cause the needle pointer to move out of the window. As shown, the invention is applied to a camera as described and claimed in Specification 952,331 having a detachable objective with a built-in diaphragm and including a setting ring 6 having cams 5, 7 operating through push-rods 4, 8 to control diaphragm and shutter speed settings. The ring 6 also carries a cam 12 which causes the follow-up needle 13 to pivot out of the exposure meter window 17 when the ring is rotated to render region B effective for flashlight photography and on entering this region a control dog 24 on the ring engages a pin 32 to close a switch 33 in the flash circuit including a shutter-controlled synchronizing switch 35, so that firing of a flash bulb cannot occur except at flashlight settings of the camera. Since the ring 6 can be rotated through any number of revolutions and hence the cam surfaces 7, 12 change their slope it is necessary in order to avoid spurious coincidences between the meter needle 16 and the follow-up pointer 13, due to the cam 12 in the range C moving the pointer 13 to disconnect the exposure meter 28, a control dog 23 on the ring 6 depressing a pin 25 to open a switch 26 as the follower pin 15 traverses the reverse slope of cam 12.
