Patent DE-68910041-D1 (DE)
Inventor: GREGORY CHARLES
IPC: F25B5/02

Granted: 1993-11-25
Abstract: A new method and apparatus are provided for sensing refrigerant temperatures in refrigerator systems, and for the control of refrigerant loading in a plurality of refrigerator evaporator circuit coils (34a,34b) connected in parallel. Such evaporator coils are supplied with refrigerant through a thermostatically controlled flow control valve (30), which is controlled by a sensor (50) to restrict the flow of the liquid refrigerant and ensure a predetermined amount of superheat. The usual minimum superheat is about 5.5 DEG C (10 DEG F) and it is often found that the evaporator coil clearly is underloaded, and in the case of a multi circuit coil evaporator, that many of the circuit coils are underloaded. To avoid this the refrigerant is rendered thoroughly turbulent and mixed, and in the multi-coil evaporator the flows issuing from all of the circuit coils are similarly thoroughly turbulated and mixed, by a turbulating and/or mixing device (48) that intercepts the entire refrigerant flow just before the sensing of the superheat, thus ensuring that the temperature is accurately measured. In the multi-circuit coil system the device averages the temperatures of all the flows, any liquid from circuits with lower heat transfer being broken, mixed with and evaporated by superheated vapour from circuits with higher heat transfer. Different turbulator/mixer devices are described and two or more such devices may be used in flow series. The amount of superheat can now safely be reduced to about 2 DEG C (4 DEG F), the efficiency of the entire system is increased, and close matching between valve size and coil loading is no longer required.

Abstract: In an apparatus for spreading and cutting layups of sheet material pin mechanisms (72) are distributed over the supporting surface of the table (12) and include pins (74) moveable between raised and lowered positions to enable selected portions of the supporting surface to be adapted, or not, to a spreading procedure involving the pinning of each layer as it is spread. The supporting surface (20) is divided into sections (70) and the pin mechanisms (72) of each section are operated in unison by a control element (114) located on the side wall of the table with each control element (114) being aligned with its associated section (70) of the table so as to be quickly and easily operable by an operator without the operator having to give great thought or attention to which pin mechanisms (72) are operated by which switch. The pins (74) passing through a layup being cut by the cutter (24) are automatically lowered upon the cutter (24) approaching the pins to avoid collision between the pins and the cutter. This latter function can be defeated, if desired, to allow the cutter (24) to be passed over a layup in a noncutting mode without pins (74) being withdrawn from the layup. <IMAGE>

Abstract: A rewritable disk (10), in which the length of the edit gap (18) is reduced to thereby achieve higher-density recording, as well as an apparatus for such disk, is disclosed. An area for recording a preformated encoding pattern (22) is provided on a rewritable disk (10) in order to obtain information of an eccentricity produced when the disk (10) is chucked. The information of the eccentricity produced at the time of disk chucking is detected, while the disk (10) is being driven, from a reference pulse (RP) obtained by reproduction of the encoding pattern and, on the basis of the eccentricity information, the frequency of the clock (WCK/RCK) for writing data or reading data is modulated according to eccentric positions. By so doing, it can be achieved to properly write data in sectors (16) even when the disk (10) is chucked with a certain eccentricity. Accordingly, it becomes so that only a length corresponding to several clocks is required for the edit gap (18). Thus, the ration between the area occupied by the edit gaps (18) and the area of the entire disk (10) can be reduced and thereby higher-density recording becomes achievable. <IMAGE>

The photodiode is used to sense the output intensity of the LED. The direct optical path between LED and sensor means that the photodiode output is insensitive to movement between the assembly and its surroundings, which movement can give rise to errors in prior art arrangements involving reflection from a further surface. The assembly may be used in an exhaust gas sensor in conjunction with a further photodiode. <IMAGE>
