Patent GB-2075731-A (GB)
Title: Improvements in or relating to data processing apparatus
IPC: G06F12/12
Filed: 1979-11-07
Abstract: A cache unit includes detection apparatus for detecting a conflict condition resulting in an improper assignment. The detection apparatus, upon detecting such a condition, advances the replacement circuits forward to assign the next sequential group of locations or level and inhibit it from making its normal location assignment. It also inhibits the directory circuits from writing the necessary information therein required for making the location assignment and prevents the information which produced the conflict from being written into cache store when received from memory.

Title: Integrating absorbance photometer
IPC: G01J1/10
Filed: 1981-06-16
Abstract: A photometer for the measurement of the absorbance of samples comprises a source of light, appropriate arrangements for selecting the colour of the light, and paths for respectively a reference and a measurement beam of light. The sample is placed in a cuvette in the measurement beam path. There is a detector of the beam from the sample and a detector for the reference beam, and an electronic circuitry for the processing of the values obtained from the measurement detector so that a desired reading is obtained concerning the properties of the substance placed in the cuvette. It is characterized by the reference detector signal being integrated from the beginning of the measurement period, and when the integrated signal reaches a threshold it terminates the measuring period. The signal of the measurement detector is integrated from the beginning to the end of the measurement period.

Title: Method and apparatus for compressing gas
Inventor: ALLAM RODNEY JOHN
IPC: F01K27/02
Filed: 1981-06-18
Abstract: The fuel required to provide the energy for compressing a gas can be reduced by compressing the gas substantially adiabatically through a pressure ratio of at least 2.5:1 in a compressor, cooling the hot compressed gas by heat exchange with water at superatmospheric pressure, further heating the water to produce super-heated steam and using the superheated steam to drive the compressor. The total amount of fuel consumed can be considerably less than that used for compressing gas conventionally (i.e. substantially isothermally).

Title: Optically readable record carrier and read apparatus therefore
Inventor: BRAAT JOSEPHUS JOHANNES MARIA
IPC: G11B7/24091
Filed: 1981-10-16
Abstract: A record carrier is described which has an optically readable information structure in which information areas 4, 4' of adjacent information track portions have different depths d1, d2 which in playback produce phase depths differing by  pi /2 radians. The read apparatus comprises two detectors 22, 23 aligned in the track direction x in the far field 40, 41,42 of a read spot. An electronic relative phase shift is applied to the signals supplied by the two read detectors. To read tracks of one phase depth, the phase-shifted detector signals are subtracted from one another, cross-talk from the signals from the adjacent tracks of the other phase depth being substantially eliminated. To read the other phase depth tracks, the phase- shifted signals are added, again substantially eliminating cross-talk from adjacent tracks of the one phase depth. The electronic phase shift is selected in relation to the phase depth difference. <IMAGE>

IPC: B65B11/00
Filed: 1982-02-05
Abstract: An automatic machine for forming and wrapping confectionery products before they are baked comprises a conveyor 1 over which a strip of heat- resistant wrapping material 5 from a roll 4 is conveyed. Confectionery raw material 8 is dispensed by a dispenser 6 on the wrapping material 5 and then filling 9 is dispensed from a dispenser 7 on the part of the layer of raw material. The wrapping material 5 is cut into sections by a cutter 11 and then the raw material 8 is folded over the filling 9 and both the raw material and the filling are wrapped up in the wrapping material sections by a wrapping device 12. The wrapped raw material is then baked. As the raw material and filling are wrapped as soon as they have been dispensed and before baking, the operations are more hygienic. The wrapping device may comprise oscillating plate 13 and rotary plate 14, which initiate folding of the material 8 and wrapping material, and one or more rotary formers 16 and 17 which connected with an inclined plate 15 to complete folding to tubular form prior to closing of the latter. In another embodiment, the wrapping device may comprise a pair of opposed twisted belts. <IMAGE>

Title: Charging batteries
Inventor: SVENSSON THOMAS
IPC: H02J7/00
Filed: 1983-03-10
Abstract: In a method and an apparatus for charging batteries using a source 3,4 which delivers a charging current which decreases with an increasing battery voltage, the charging current is continuously integrated 14, to determine the total number of ampere hours supplied, the rate of change of the charging voltage is determined 15 and the maximum value of the rate of change established the time (T2, Fig. 1) at which the rate of change of the charging voltage again falls to a predetermined percentage, for example about 40-50%, of its previously established maximum value is then established and charging of the battery is continued from this time (T2) until the battery has been supplied with a further number of ampere hours constituting a predetermined percentage, for example about 10- 15%, of the total number of ampere hours supplied to the battery up to the aforesaid time (T2). Charging of the battery is then discontinued. The battery may subsequently be trickle charged, e.g. by connecting it to the charging current source for a predetermined short period as soon as the battery voltage has fallen to a predetermined level. Calculation of the rate of change of charging voltage may commence only when the charging or battery voltage has reached a predetermined value; the battery may be charged-with a higher current until that time. Means 6,9 may be provided to compensate for mains voltage variations when determining the rate of change of charging voltage. Calculations and control may be effected by a microprocessor 12, and a display 20 may indicate main charging time, additional charging time, total charging time, ampere hour, charging voltage, and charging current. <IMAGE>
