Title: Improvements in or relating to master cylinders for hydraulic brake systems
Inventor: FRANZI RICCARDO
IPC: B60T11/20
Filed: 1970-04-02
Abstract: 1,254,089. Master cylinders; valves. FIAT S.p.A. 2 April, 1970 [3 April, 1969], No. 15567/70. Headings F2F and F2V. A master cylinder, for an automobile hydraulic brake system including a slave cylinder, comprises a cylinder 2, a control piston 4 at one end of, and slidable within, the cylinder in response to an external control and defining a compression chamber 3 between the piston and the other end of the cylinder, a brake fluid inlet 35 including a passageway 34 for supply brake fluid from a fluid reservoir to the chamber, and a valve 33a for controlling flow of brake fluid through the. passageway, the valve having a cylindrical guide section 33 for sliding movement in the passageway. There are also an outlet pipe connection 44 for feeding brake fluid from the chamber to the slave cylinder, a coaxial shaft 27 having one end connected to the piston for relative sliding movement therewith, the other end of the shaft carrying the valve, and biasing means, i.e. springs 42, 43 for returning the piston after operation thereof, the springs being adapted for operating the valve to control the flow of brake fluid through the inlet 35. At least one groove 39, formed in the guide section 38, extends longitudinally from the outer end of the valve, and an annular jointing ring 40 is disposed on a flange 32 of the guide section. The arrangement is such that, in operation, the piston is moved for sliding movement in the chamber by activation of the external control to urge the valve for sliding movement in the passageway 34 and against the biasing means whereby the ring 40 provides a fluid-tight seal between the passageway and chamber 3, the piston movement increasing the brake fluid supplied through the outlet pipe connection for actuation of the slave cylinder, and deactivation of the external control causing or allowing the biasing means to return the piston whereby the fluid-tight seal is broken to release the fluid pressure and to allow supply of fluid from the inlet to the chamber. As shown, the shaft 27 is connected to the piston by a retaining member 17. In a modification, there are two master cylinders in tandem controlling separate braking circuits and each piston includes a valve as shown in the figure; the valve 33a of the piston 4 moves in a bore in the other piston and communicates via an annular recess in the latter piston with a reservoir passage in the side wall of the cylinder.

Title: Digital communication synchronization system
Inventor: SALAVA ROGER FRANKLIN
IPC: H04L7/04
Filed: 1970-04-02
Abstract: 1,253,944. Synchronizing systems for transmitters and receivers. MOTOROLA Inc. 2 April, 1970 [16 April, 1969], No. 15569/70. Heading H4P. A system for synchronizing a receiver such as as a teleprinter by means of a first synchronizing signal produced by a transmitter comprises a shift register 19 with feedback at the receiver for generating a second synchronizing signal identical to the first signal, a gate 25 responsive to the first and second synchronizing signals to develop a first output signal when the first and second synchronizing signals are the same and a second output signal when the first and second synchronizing signals are different, an integrator 27 for adding the first output signals and subtracting the second output signals to develop a first control signal, and a level detector 28 responsive to the first control signal which exceeds a predetermined magnitude to develop a synchronization control signal. Initially, an AND gate 24 is disabled whilst an AND gate 17 is enabled so that the incoming first synchronizing signal is coupled to the shift register 19. If there are no errors in the incoming signal, the output of an adder 22 is identical to the incoming signal and is applied to the gate 25. When a predetermined number of correct synchronizing signal digits have been received, the quantity stored in the integrator 27 reaches a predetermined level which is detected by the level detector 28 to develop a control signal which enables the gate 24 and disables the gate 17. If now a number erroneous synchronizing signal digits are received, the receiver continues to generate the second synchronizing signal without losing synchronization. However, if the number of erroneous digits is large and synchronization is lost, the output of the detector 28 is cut off, thereby disabling the gate 24 and enabling the gate 17 so that the incoming synchronizing signal is again coupled to the shift register 19 to re-establish synchronization. When the stages of the shift register have a predetermined signal, signals from the stages and from a delay 31 enable an AND gate 33 to provide an output signal which starts various circuits for receiving the address and the data signal for printing.

Abstract: 986,379. Winding layouts for dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 4, 1963 [April 24, 1962], No. 15612/62. Heading H2A. In a system of pole-changing by poleamplitude modulation effected by applying a single pole-amplitude modulation wave applied to the three-phase winding as a whole two modulated pole-numbers are obtained, one by the use of a modulation wave having an odd number of cycles, and another by the use of a modulation wave having an even number of cycles. Each phase winding is divided into four sections and the winding is connected in four-parallel star for one pole number (preferably the lowest), in series-parallel star for the intermediate pole number, and in series star or delta for the third pole number (preferably the highest). Fig. 7a shows an 8-pole, 120 degrees spread winding in 18 slots, the coil grouping per phase being alternately one and two coils per pole-pair, and the original phase sequence A, C, B. The modulation operator M-M indicates those coils under this operator which are reversed, and shows a 7-cycle modulation wave which transforms the winding to 6-poles. Fig. 7c shows a 6-cycle modulation wave applied to the same winding to produce 4-poles. In each modulated condition the phase sequence becomes A, B, C. Fig. 7f (not shown) shows how a 9-cycle modulation gives 10 poles. It is also described (Fig. 7d, also not shown) how these winding transformations are related to 4/6 pole transformation of the same winding by a single-cycle modulation, and the whole inter-relationship of the four pole numbers is set out in diagrammatic form in Fig. 6a (not shown). The correct slots to reverse are determined by slot-star diagrams Figs. 7b, 7e, not shown) showing the phaseangle of each slot with respect to the modulated pole-number.

Patent GB-158125-A (GB)
Abstract: 158,125. Preston, E. E., and Mercia Fabric Co., Ltd. Nov. 12, 1919. Knitted fabrics.-An improved fabric of the uniformly-faced type is made on double-rib warp machines by means of one fully-threaded guidebar only, by lapping each individual thread over two needles so that each needle carries two threads at each lap. Each thread, after lapping two needles on, say, the front needle-bar f, crosses over to the rear needle-bar b and laps two needles in the same direction, then crosses back to the front needle-bar f and laps two needles in the opposite direction, and finally completes the cycle by crossing over to the rear needle-bar b and lapping two needles in the opposite direction to the previous lap on this bar. This cycle of movements can be used in conjunction with any convenient movement of the threads between the needles, and the threads may be moved to the right or left over the front and back needles provided that when lapping the needles such threads all move in the same direction at the same time. The fabric is adapted for production on a machine fitted with knocking-over means of the type described in Specification 11969/15, and with thread let-off and tensioning devices as described in Specification 132,931. According to the Provisional Specification, the improved fabric may be made on a machine fitted with one row of needles.
