Title: Ram and Vehicle Cab Tilting Arrangement Incorporating Same
IPC: B62D33/07
Filed: 1979-08-10
Abstract: A hydraulic ram 10 especially suitable for controlling a tiltable cab of a motor vehicle which passes through an over-centre intermediate position has a lost motion coupling slot 46 of which the effective length is controlled by a movable end member 40. In the rest position end member 40 is retracted permitting a limited amount of free movement between parts interconnected by the ram. In an operating stroke pressurised fluid supplied to chamber 14a of ram cylinder 12 passes through a valve- controlled passage in an internal partition 18 and preferentially activates a spring-loaded secondary piston 38 to displace end member 40 and take up the lost motion before operating smaller diameter driving piston 22 to extend the ram. Valve 72 closes to trap pressurised fluid when piston 22 moves so that lost motion slot 46 remains closed up and prevents lost motion, thereby maintaining rigid control and preventing any jerk in any change between compression and tensile loading of the ram, throughout the entire operating stroke. <IMAGE>

Title: Control of broadcast radio and television receivers
IPC: H03J1/00
Filed: 1979-10-16
Abstract: A television or, as shown, radio receiver (10) is provided with a light pen (12) capable of reading bar codes in a broadcasting periodical (18), these codes then being applied to a store (30) in the receiver. The programme codes comprise a station reference number and a time indication. When the time approaches, the station reference number is addressed in a frequency directory (34) and the corresponding frequencies located. A detector (42) determines which of the frequencies provides the strongest signal. In the absence of a frequency in the directory, or in response to manual actuation of a button (50), the tuning is successively swept across the entire tuning range and signalling carried by the radio signal is detected (48). These signals may include information characteristic of the station and of the transmitted programme, i.e. a channel code and a time code. The time code is compared (36) with the stored programme time and an alarm (60) activated. If a button (62) is depressed, the receiver A.F. circuits (24) are de-muted, but if the button is not depressed the programme is recorded (64). Frequency information can be directly entered into the directory (34) using the light pen (12).   <IMAGE>

Title: Fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1981-06-29
Abstract: A fuel injection pumping apparatus comprises an axially movable distributor member 12 the axial setting of which determines the amount of fuel supplied by the apparatus at each pumping stroke. The distributor member is biassed by a spring 29 in one axial direction and is movable in the opposite direction by varying the fluid pressure in a chamber 30. Liquid under pressure is supplied to this chamber through a restrictor 30A and the pressure in the chamber is controlled by a controlled leakage from the chamber through a port 63. The port 63 is formed in a sleeve 62 which is coupled to the distributor member by means of a feed back lever 66 and a rod member 64 is axially movable within the sleeve by governor 68 or manual connection 73. The axial position of the rod member can be varied to alter the effective size of the port 63 and the distributor member and sleeve move because of the change in pressure in the space. A new equilibrium position is thus established with the distributor member following the movement of the rod member. <IMAGE>

Title: Colour information display system
Inventor: JONES OWEN MELLOR
IPC: G09G1/28
Filed: 1982-01-07
Abstract: In a computer-generated colour- graphic display, the quality may be improved at the expense of colour- range by using one item of time or phase information in each reference period of a signal to define mode: for example the fourth (M) bit out of each 4 bit reference period may be used. Different effects are produced when the system is running in text mode or in low or high definition graphic modes. A background colour can be defined and temporarily substituted for the signalled colour in subsequent periods. Reference periods with only a mode bit present cause advance of a 2 bit counter so that four different modes are available for entry by a subsequent reference period having mode bit plus one or more of R, G, B bits. <IMAGE>
