Title: Stacking apparatus in memory controller
IPC: G06F13/18
Filed: 1979-03-27
Abstract: Commands (read destructive, read non-destructive, write, etc), with addresses and data are stored in a stack 40 from various units (CPU, IOC). A counter 60 for each stack location (LVO to LVn) counts up to indicate the age of the command, and compare priority logic 85 selects the oldest command for reading and forwarding to the appropriate one of 8 memory units. The memory unit field MUF of each command is decoded and checked, logic 111, to see if the memory unit is free; if it is not, the count is prevented from reaching the compare priority logic. Each location also has a busy flip-flop 34, set when a command is written into the location and cleared when it is read out. The busy flip-flops feed write priority logic 30 which selects the lowest free level in the stack for the next incoming command to be written in. <IMAGE>

Title: Automatically adjusting valve clearance
IPC: F01L1/22
Filed: 1979-08-15
Abstract: An automatic tappet adjuster for a valve operating mechanism has two components 12, 14 with co-operating buttress thread form screw threads 32. The axial free play in the threads 32 sets the valve clearance. Excess clearance 56 is taken up by rotational movement of one component, 14 acted on by a spring 40, relative to the other component 12. When component 14 is loaded by the cam 24 during the valve opening movement, component 14 first moves to take up the clearance and then wedges in component 12, due to the flank angle of the threads so that the cam thrust is transmitted to the valve. When excessive clearance exists, spring 40 acts downwards on component 14 while it is not loaded by the cam and it rotates to reduce the clearance. An embodiment is described in which the adjuster is located within a bucket-type tappet of an overhead camshaft engine. <IMAGE>

Patent GB-2062980-A (GB)
Title: Inverter
IPC: H02M7/515
Filed: 1980-11-13
Abstract: A self-commutating inverter supplies controllable frequency power to a load. The load, which may be a simple induction motor or the like, has plural load windings (A, A', B, B', C, C') which may be arranged in two groups so that a load winding in one group has a complementary load winding in another. Thyristors (TA, TA', TB, TB', TC, TC') are associated with each of the complemented load windings and the thyristors of each group of load windings are capacitively coupled (C1 to C6). A DC potential is applied to the inverter by a pair of terminals. As different thyristors are enabled, current is commutated from one load winding to another. Excessive voltages induced by commutating the inductive loads are reduced by diodes (RA, RA' to RC, RC') coupled between a terminal and a divided load winding. For producing three phase power of controlled frequency, the load has six windings, forming two groups of three windings each. The thyristors associated with each group of windings conduct periodically in a sequence, with each thyristor conducting for one third (or 120 DEG ) of the period. While the conduction periods for each of the groups of load windings are equal, they are offset in time by one- sixth (or 60 DEG ) of the period. <IMAGE>

Patent GB-2089767-A (GB)
Title: Liquid dispensing apparatus
IPC: G01F3/18
Filed: 1980-12-18
Abstract: In a liquid dispensing apparatus, liquid passes in either direction through a cylinder (24) by means of valves (20, 16 or 22, 18). As movement of a piston (26) approaches an end of the cylinder (24) to register a discrete quantity of the fluid, a coil externally of the cylinder (24) senses the position of the piston (26) and effects change-over of the valve paths prior to the piston (26) reaching the end of the cylinder (24). This enables opening of the valves in the other valve path before the differential pressure across the other valves becomes significantly large. Dispensing of a fluid is continuous and when dispensing has stopped, a memory device remembers the direction in which the piston (26) was travelling such that the piston can continue in the same direction when dispensing is resumed. The number of complete strokes of the piston (26) can be counted to record over a period of time the amount of liquid which has been dispensed to a very high degree of accuracy. <IMAGE>
Patent GB-2071242-A (GB)
Title: Improvements in Hydraulically- operated Anti-skid Braking Systems for Vehicles
IPC: B60T8/46
Filed: 1981-01-30
Abstract: An hydraulically-operated anti- skid braking system includes a pump (3) driven by rotation of a wheel to be braked and of the type which, once a predetermined minimum wheel speed is attained, produces a constant output flow irrespective of any further increase in the wheel speed, and a fixed orifice (40) through which the output flow from the pump (3) is circulated to provide a back pressure which is utilised to control the application of a brake. Since the pump (3) is driven with a wheel to be braked by the brake, the wheel is automatically prevented from locking. The pump output, the product of the pumping frequency and pump stroke is constant as the pump piston return speed is held constant by a bleed orifice (41) and hence the stroke decreases with increasing wheel speed. <IMAGE>
Patent GB-2092870-A (GB)
Title: Acid dip for dosemeter
IPC: G01T1/11
Filed: 1981-02-06
Abstract: Background signal in a PTFE based dosemeter caused by impurities in the PTFE and in the active component such as lithium fluoride is substantially reduced by treating the dosemeter with acid the background signal. The optimum treatment involves use of hydrofluoric acid at room temperature for approximately one minute, followed by thorough washing with methanol, and finally drying. This treatment is best applied after the original manufacture of the dosemeters. It may also be applied to existing dosemeters after they have been in use for some time. The treatment produces a permanent effect in reducing both the light induced signal and the non-light induced signal. The process may be applied to all types of dosemeter manufactured from PTFE or other plastics or resins which are able to resist brief exposure to acid. The treatment works particularly well with dosemeters based on PTFE and lithium fluoride. It is also applicable to dosemeters based on calcium sulphate, lithium borate and magnesium borate. Acids which may be used include hydrofluoric, hydrochloric, nitric, phosphoric and sulphuric.
