Title: Improvements relating to the control of the clutch mechanism of the engines of motor vehicles and the like
IPC: B60T13/02
Filed: 1929-10-11
Abstract: 340,062. Roe, J. E. Oct. 11, 1929. Control-transmitting apparatus.- A dash-pot mechanism for automatically controlling the rate of engagement of a clutch on motor vehicles or power units, is so arranged that said rate of engagement is dependent, in direct proportion, upon the road speed of the motor vehicle or on the speed of a moving part of the power unit to which said clutch is fitted. A dashpot 1 connected to a clutch pedal 2 through a member 5 and a ball and socket joint, comprises a piston 12 having apertures 15 controlled by a spring loaded check valve 17, a cylinder 11 the block of which has passages 25, 26 connected together by a bore 27 carrying an adjustably loaded spring-controlled valve 28, 31, 30 and connected to a bore 38 which communicates with a rotary pump device 35, 36 driven by a shaft 6 from the speedometer of the motor vehicle or some moving part of the power unit. A bore 39 connects said pump 34 to an extension 40 of an oil reservoir 20 which communicates through a bore 21 with a jacket 22 round the cylinder wall 11, and longitudinal slots 24, 23 spaced round the surface of the cylinder 11 connect said jacket with the interior of the cylinder 11. When the clutch pedal is depressed the piston 12 moves from right to left, Fig. 6, and oil flows through the valve 17 from left to right. On releasing the pedal the piston returns under the action of the clutch spring, oil flowing through the slots 23, 24 and jacket 22 from right to left. When the piston 12 passes the slots 23. 24 its movement is retarded, oil then flowing through the passages 25, 27, 38, the stationary rotary pump 34, passage 39, extension 40 of the reservoir 20, the reservoir 20, passage 21, slots 23 and 24 to the left hand side of the piston 12. Fluid pressure at the point X closes the valve 28. While the piston is passing and obtruding the bore 25, the clutch is on the point of engagement and oil flow ceases thus relieving the pressure at X to open the valve 28 and permit flow through the bore 26, valve 28, bores 27 and 38 &c. thus nearly closing the valve 28 again. At this point the vehicle or the moving part of the power unit, begins to move and the rotary pump 34 operates to reduce the pressure X thus fully opening the valve 28. The rate of engagement thereafter is dependent on the rate at which the pump 34 transfers oil from one side of the piston 12 to the other. For reverse drive the. action of the dash-pot is the same as described above until the pump 34 commences to rotate when the reverse rotation causes an increase of pressure at the point X thus closing the valve 28 and preventing further flow of oil in either direction in the cylinder 11. The clutch thus remains engaged, and oil is drawn from the reservoir 20 and returned via the bore 25 to the left hand side of the piston 12.

IPC: G01C1/06
Filed: 1957-10-04
Abstract: 884,381. Indexing means for gear gauging apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 5, 1959 [Oct. 4, 1957], No. 31112/57. Class 106 (2). [Also in Group XX] Apparatus for measuring the angular motion of a body about a fixed axis passing therethrough, or for dividing said motion into determined angular steps comprises a light wedge formed by two plane light reflecting surfaces relatively inclined at an acute angle and one or more light-reflecting surfaces arranged to have rotation imparted to it or them in accordance with the rotation of said body and to reflect a beam of light on to the wedge so that the beam is returned by the wedge in its plane of incidence. As shown in Fig. 4 a light wedge of angle # is open at its apex and light from a source 3 is passed through the apex to a reflector 4 carried by a rotating body so that, each time the reflec- # tor completes a rotation through an angle -, 2 the light beam returns along its incident path. The rotating reflector may be mounted on a body to which is attached a toothed wheel to be checked (Fig. 12, not shown). The returning ray may be viewed by an auto-collimator the indication of each successive step of angular movement of the body being obtained by the successive presentations of an image of the auto-collimator slit in the field of view. Alternatively the image of a graticule projected on to the moving mirror may appear on a scale. To cover more than 90 degrees of movement, several mirrors 4 may be provided in the form of a cube or polygon or the incident path of the light beam may coincide with the axis of rotation of the body carrying a prism having one or two reflecting surfaces. When the prism has only one reflecting surface, two light wedges may be provided as shown in Fig. 8. The direction of the light ray from the source may be inclined to the plane of Fig. 9 so that the ray ultimately reflected from the light wedge may fall on the viewing surface 7 and a scale 8. To allow for continuous indication of angular position there may be provided as shown in Fig. 10 two mirror cubes which turn simultaneously about a common axis but are relatively displaced by the angle #/4. In this case there are two light   wedges and two scales are provided so that at the commencement of one increment and the completion of another an image appears at the opposite ends of the respective scales. This may also be achieved by use of a single wedge and a single mirror cube.

A method of severing material into predetermined lengths comprises feeding the material along a path, intersecting the path at fixed intervals of time with shearing means, and synchronizing the feeding with the intervals of time. Apparatus for carrying out the method consists of upper and lower rotating members secured to gears 30, 30<SP>1</SP> so as to rotate in unison about shafts 24, 24<SP>1</SP>, one of the gears being driven by a motor. Each member consists of spaced plates 21 between which are holders 34 for blades 35, 35<SP>1</SP> disposed radially of the members. A conveyer C is disposed for feeding logs between the members so that the blades 35, 35<SP>1</SP> cut the logs into predetermined lengths. When a log is fed along the conveyer it actuates a limit switch LS1 to stop the log until a camming switch driven by one of the members is actuated to re-start the conveyer so that the feed of the log is synchronized with the shearing by the blades. The blades are mounted so as to be vertical at the shearing point. In another embodiment, the blades are mounted on pivots between the plates of the members and connected by a linkage to a cam follower movable by a cam whereby during the whole of the cutting action, the blades are maintained in a vertical position.

Title: Transmitter and receiver circuits for the sequential storage colour television system
IPC: H04N11/18
Filed: 1975-07-25
Abstract: 1488756 Television systems THOMSONCSF 25 July 1975 [26 July 1974] 31320/75 Heading H4F In a S.E.C.A.M. type colour television system the transmitted signal comprises, during each line, a portion of the luminance signal spectrum and one of the colour signals modulated on a sub-carrier. For example, during every other line the portions Yb and Yh1 of the luminance spectrum is transmitted, the remaining portion being suppressed and the colour signal on subcarrier SR being transmitted in its place, Fig. 1a. During the intervening lines the portions Yb Yh2 are transmitted, portion Yh1 being suppressed and the other colour signal on sub-carrier SB being transmitted in its place, Fig. lb. This arrangement reduces cross modulation of the luminance and colour signals. At the transmitter, Fig. 2 (not shown), the luminance signal is directed by a half line frequency switch (6), alternately to a low pass filter (7) having a cut-off at 5MHz and to a band stop filter (8) which stops 4-5 MHz. The filters feed an adder (9) which also receives, during alternate line periods, the one and the other colour signals modulated as respective sub-carriers SR, SB. At the receiver, Fig. 3, the received signal passes via half line frequency switch 22 to low pass filter 17, which has a cut-off at 5 MHz, and band stop filter 18, which stops 4-5 MHz, the filters feeding adder 19. The portions of the luminance spectrum absent from the filter outputs, i.e. Yh1 from 18 and Yh2 from 17, are obtained from the preceding line by way of 1- line delay 27. Filter 26 passes to the delay the portion of the received signal lying above 4 MHz. The delayed signal passes via half line frequency switch 28 alternately to filters 29, 30 which respectively pass the portions Yh1 and Yh2 to the adder, so that the adder output is the complete luminance signal. Half line frequency switches 33, 35 receive both the delayed and undelayed portion of the received signal lying above 4 MHz, and feed a low pass filter 32 and a high pass filter 36 which extract respective modulated colour sub-carriers.
