Title: A composite image arrangement for documents of value
Inventor: GREEN IAN MACDONALD
IPC: B41M3/14
Filed: 1993-10-07
Abstract: A composite image arrangement, for use as an anti-counterfeiting measure on documents of value e.g. banknotes, comprises two parallel patterns, each having relatively more (3, 4) and less (2, 5) light-transmissive regions. The patterns (Fig.2) appear random in isolation, and are in fixed positions on either side of a light transmissive lamina (1) e.g. a sheet of translucent paper, and precisely aligned to give a non-random transmitted image when viewed together in transmission. The transmitted image may be visible in a restricted range of angles only. A method of manufacturing such an arrangement comprises (a) providing a random two-tone pixel pattern, (b) providing a non-random two-tone image pattern, (c) combining the image pattern and the pixel pattern using a combining function (for example, exclusive or) to form a further random pattern, and (d) aligning the two random patterns on either side of a light-transmissive lamina to give an approximation of the image pattern when viewing both random patterns together in transmission. <IMAGE>

Title: Rotation transmission device
Inventor: ITOH KENICHIRO
IPC: B60W30/18
Filed: 1994-06-08
Abstract: A device for mechanically changing over the direction of transmission of a turning force comprises engaging elements (5) such as sprags or rollers mounted between a driving member (2) and a driven member (1) and has means for preventing noise resulting from the repeated engagement and disengagement of engaging elements (5) when a turning force is applied from the driven member 1. The sprags (5), and sprag-supporting retainers (3, 4) are provided between an outer ring comprising the driven member (1), and an inner member which comprises the driving member (2). A resilient member (36) is mounted between the outer ring (1) and the inner member (2). When a turning force is transmitted from the outer ring to the inner member, the inner member and one of the retainers (3, 4) begin rotating first, biased by the elastic member (36). The retainers thus rotate relative to each other, inclining the sprags (5) in the same direction as the inner member (2), to a ready-to-engage position. The sprags are thus prevented from repeatedly engaging and disengaging, so that noise is reduced. A member (9) applies a greater turning effort to the retainers than a member (7) and the turning effort of the members (36) is greater than that of the members (7). (Figs 8 - 10) and 12 and 13) depict weighted modifications of the spring (7). Particular sprags may engage only when inclined in one direction, A further one-way clutch (8) is provided. <IMAGE>

Patent GB-950131-A (GB)
IPC: F16K17/10
Abstract: 950,131. Valves. HYDRAULIC UNIT SPECIALTIES CO. Dec. 1, 1961 [Dec. 1, 1960; Nov. 6, 1961 ; Nov. 17, 1961], No. 43153/61. Heading F2V. [Also in Division G3] A flow control valve for relieving both high and low pressures comprises a valve housing 18 having a supply line port 24 and a reservoir port 25, the flow between which is controlled by a valve closure 23 co-operating with a seat 19. The valve closure is formed on the end of a main poppet member 21 having a piston portion 26, loaded by a spring 22, slidable in a cylinder 20 and forming a pressure chamber 55. The pressure in the chamber 55 is normally maintained substantially equal with that at the port 24 by means of plunger member 59 formed with a longitudinal bore 63 whose end co-operates with a ball check valve 60 such that flow from port 24 to the chamber is restricted by a throttle passage 59 while flow from the chamber to the port opens the ball valve to provide free flow. A spring loaded pilot valve 36 controls flow from the chamber 55 to exhaust. In operation as the pressure at the port 24 rises so will that in the chamber 55 rise until the pressure reaches a predetermined value to open the pilot valve 36. Fluid flows freely from the chamber 55 to exhaust and the pressure at port 24 acts to open the valve 23 to allow flow from port 24 to the port 25. The increased pressure in port 24 to that in chamber 55, due to the throttle, acts to move the plunger 59 which holds the pilot valve open until the pressure at port 24 falls to a value at which the spring 38 closes the pilot valve. Fluid then flowing to chamber 55 balances the pressure at the port 24 and the spring 22 closes the valve 23. When the fluid pressure in port 24 falls fluid flows from chamber 55 freely past the ball 60 and when the pressure in chamber 55 falls below a predetermined value, the pressure in port 25 acting on the area 56 of the piston 26 opens the valve to allow flow from the port 25 to the port 24. This increase in pressure acts on the plunger 59 to move it into abutment with the pilot valve. Such movement increases, by its displacement, the pressures in the chamber 55 to bring this pressure rapidly to a value at which the valve 23 again closes and as flow takes place past the throttle portion of the plunger 59, the plunger gradually assumes the position shown. In a modification the plunger 59 and ball 60 are replaced by a cylindrical piston element which may be lightly loaded and the passage to the chamber 55 is partially oblique to the axis whereby movement of the plunger provides throttling or free flow under the above conditions. The flow past the pilot valve may take place to the port 25. In a further modification the main valve is formed as two valve members having inner and outer members of which one is seated on the other, the inner valve moves to relieve excess pressure at port 24 while they both move to relieve negative pressure at this port.
