Title: Tubular pipe connector - is moulded and has an annular channel in its inner surface for location of sealing ring
IPC: B29C45/44
Filed: 1972-06-02
Abstract: A tubular pipe connector is moulded in an annular cavity between a pref. cylindrical outer mould and a centre block arranged within the outer mould. The centre block includes a stationary cylindrical part and a movable part having a frusto-conical portion around which an elastic ring is located whereby when the movable part is moved (e.g. by a pneumatic ram) towards the stationary part the ring engages a seat on the stationary part and slides along the frustoconical portion and expands radially such that it projects into the cavity and forms an internal annular channel in the pipe connector. After moulding the movable part is moved away so that the ring slides down the frusto-conical portion and contracts thereby allowing the pipe connector to be removed. A number of pref L-shaped metallic feet are posnd. with one branch between the elastomeric ring and the frusto-conical portion and the other branch extending along the radial face of the elastomeric ring which is contacted by the seat, and pref. the two branches are inclined at 90 degrees.

Title: Programmable sequencer - for control of advertisement and shop window displays
IPC: G05B19/07
Filed: 1973-03-19
Abstract: A series of interconnected electromagnetic relays each have at least one pair of fixed and one pair of moving contacts. The supply of current to a number of controlling devices which supply power to the display is determined by opening and closing the moving contacts. The tim delay during which each relay is in a given state is adjustable. The sequence is started by supplying the first relay in the chain with current via its fixed contacts. After a preset delay its open contacts close and its closed contacts open and either complete or interrupt the current supply to one or more of the display controllers and at the same time trigger the next relay in the chain which in turn reverts to its initial state after its preset time dlay and triggers the following relay and so on to th end of the chain where the final relay restarts the sequence. The complete output sequence is determined by the initial states and preset time delays of each individual relay. Electrical or electronic means may be used to implement the delay.

Title: Duck board formed from grid of plastic straps - metal inserts in straps strengthen the interlocking straps
IPC: E04C2/42
Filed: 1973-06-13
Abstract: The duck boards are made up of sections which consist of strips which have recesses to form half joints with other strips, thus creating the grid that forms the duck board.

The shape and position of the metal insert is important. The duck boards can support similar loads as the metal ones. The metal strips extend through either the upper or lower halves of the strips depending on which halves of the strips have the recesses.

Abstract: In a hydraulic circuit the fluid contains electrically conducting imparities which affect the efficiency of the fluid. Detection that an impurity limit has been exceeded produces a warning indication. An adjustable resistor (9) is connected in series with a warning lamp (8) and a number of identical resistors (3 to 7) across a voltage source (2) producing a voltage (V) between terminals (2a, 2b).
