Title: Improvements in or relating to control systems for drivelines including continuously-variable-ratio transmissions
Inventor: GREENWOOD CHRISTOPHER JOHN
IPC: B60W10/101
Filed: 1993-04-13
Abstract: A vehicle driveline including a control system subject to operator demand, and a continuously-variable-ratio transmission (CVT) including a variator of torque-controlled type, in which the control system includes a performance "map" of optimum relationships between engine torque and speed over a range of values of those two quantities, and in which the control system regulates both the energy input to an engine and also the reaction torque at the variator so as to seek a state in which the mapped optimum relationship between engine torque and speed is maintained. The variator may be of the toroidal-race rolling-traction type, reaction torque within it being regulated by controlling the operating force applied to the variator rollers. The control system may act so as to compute the variator reaction torque with relation to two alternative calculations based on the transmission input and output torques respectively, and may choose for operation at any given time the calculation yielding the lesser value of that variator reaction torque. <IMAGE>

Title: RF circuits with microstrip coupler
Inventor: MUTAVDZIC VLADAN
IPC: H01P1/203
Filed: 1994-11-16
Abstract: In RF circuits having a microstrip coupler with interdigitated fingers (1 to 4), resonances may occur on the coupler characteristic within the band pass of the coupler. These undesired resonances can be reduced and even entirely removed by adopting an interdigitated structure in which no intrusion by any finger of one of the transmission lines (12) occurs between the pair of inner fingers (1, 2) from the other transmission line (11). The reduction and/or removal of these resonances appears to result from an electrical shielding effect of each of these inner fingers (1, 2). Thus, each one (1, 2) of the inner fingers effectively shields the neighbouring outer finger (3, 4) of the one transmission line (12) from the other inner finger (1, 2) of its transmission line (11), and so no inter-coupling of the RF field occurs between said outer finger (3, 4) of one transmission line (12) and said other inner finger of the other transmission line (11). Thus, this interdigitated structure provides coupling between the first and second transmission lines (11 and 12) along only one (and not both) of the edges of these interdigitated fingers (1 to 4). <IMAGE>
Patent GB-945423-A (GB)
Abstract: 945,423. Heat pumps. WORTHINGTON CORPORATION. Oct. 9, 1961 [May 2, 1961], No. 36157/61. Heading F4H. In a heat pump system, the outputs of heat exchangers are connected to common storing and separating means 20 which separates refrigerant into gas and liquid, the gaseous and liquid refrigerant being circulated by a compressor 1 and pump 40 respectively. The system shown comprises an outdoor heat exchanger 11 over which air is passed by fan 12, and a heat exchanger 24 having connections 26, 27 for water or other fluid to be heated or cooled. A cooling, heating, defrosting or intermediate cooling cycle can be obtained by selective opening of solenoid or manually controlled valves 7, 8, 9, 34, 35 and 51. For a cooling cycle, valves 7, 34 and 51 are opened, and gaseous refrigerant drawn from the accumulator 20 is supplied by the compressor via valve 7 to heat exchanger 11, where it is condensed and collects in outlet header 14; the condensed refrigerant is returned to the accumulator via check valve 30, line 16 and high pressure float regulator 17, a portion flashing into gas and the gas and liquid separating as indicated by the broken line. At the same time, the liquid refrigerant in the accumulator is supplied by pump 40 to lines 43, 44 containing check valves 45, 46. The pressure of the gaseous refrigerant passing through valve 7 prevents flow through check valve 45, and the liquid refrigerant therefore passes through valve 46 to the heat exchanger 24 where some of it is evaporated. The gas/liquid mixture collected in outlet header 28 is returned to the accumulator via valve 34. Oil which collects in the accumulator 20 is recovered via valve 51, bleed line 50 and superheat sensitive flow control 53, the oil-rich refrigerant being evaporated at 52 and returned to the suction side of the compressor. For a heating cycle, valves 9 and 35 are opened in plate of 7 and 34, thus causing the gaseous refrigerant to flow to heat exchanger 24 where it is condensed and gives up heat to the fluid in pipes 26, 27, and the liquid refrigerant to pass through heat exchanger 11. For a defrost cycle, valves 8 and 35 are opened and the pump 40 and fan 12 are not operated. The valve 8 has a pressure-reducing constricted orifice so that the refrigerant gas supplied from the compressor 1 is superheated on the downstream side of the valve, this superheated gas being passed through the heat exchanger 11 to remove the ice collected during heating cycles. For an intermediate cooling cycle, valves 34, 35 are opened and the compressor is not operated. The pump 40 passes liquid refrigerant in parallel through both heat exchangers, the refrigerant being cooled by the air flowing over heat exchanger 11 and taking heat from the fluid passing through heat exchanger 24. In a modification (Fig. 6, not shown), the liquid refrigerant flows in series through the two heat exchangers. The refrigerant gas may be superheated before it enters the compressor (Fig. 5, not shown). In a further modification (Fig. 7, not shown), the high pressure regulator 17 is replaced by a receiver connected to an upright accumulator via a level-regulating control valve.

IPC: A61B5/107
Filed: 1997-07-08
Abstract: A body moulding 1 carries a separate foot support platform 5 and an integral heel stop 6 upstanding at the rear of the platform which is supported by an integral leg 8. A slider 12 is engaged with the platform 5 for sliding movement in a front-rear direction, and includes an upstanding toe stop 14. The platform 5 carries a length scale 21 from which the length of a foot can be measured according to the position of the slider along the platform, and a tape 20 is received in slots 19 on opposite sides of the slider 12 to form a width gauge for measuring the absolute width of the foot. The width gauge 20 is adjustable in a front-rear direction independently of the slider to allow the foot to be measured at its widest part. A relative width gauge is formed by a relative width scale (24, fig.6) carried with the slider, and an absolute width scale (23), carried by the platform, comprises a series of parallel bands representing values of absolute width and which are inclined relative to the movement of the slider to intersect the relative width scale (24). Thus, the absolute width of the foot as measured by the absolute width gauge 20 can be read on the scale (23), and by noting the point at which the relevant band intersects the scale (24) the absolute width can be related to the length of the foot to provide a relative width reading.
