Abstract: 1,196,199. Automatic control of refrigeration apparatus. HONEY WELL Inc. Dec. 4, 1968 [Dec. 6, 1967], No.57665/68. Heading G3R. A control system for a chilling apparatus comprises a plurality of refrigerator units 13-13<SP>111</SP> arranged in series parallel among which a cooling load is selectively distributed by a digital computer 42 to achieve and optimum power input. The desired water temperature is set by a control 45 which may be a sensor responsive to outdoor temperature the output from which is compared with a signal from an outlet temperature sensor 50. Each unit e.g. 13 comprises a motor 15, condenser 14, and a temperature controller 32, the set point of which is adjusted by computer 42 and compared with an outlet temperature signal from a sensor 33, which adjusts the output of the compressor by a suction damper (not shown). Differential temperature measurements are made at 63, 64 and 55, 60 and forwarded to the computer together with flow measurements at 52, 53, power measurement 31, and inlet temperature measurement 51. This information is compared with a number of preset values stored in the computer, say in the form of a matrix and when identity is reached, signals are sent out e.g. on a line 43 to operate control relays to energize the respective motors. The units 13-13<SP>111</SP> may have equal or unequal outputs. The comparisons are revised say every twenty minutes and the set values are changed at these intervals accordingly. Comparisons of power inputs are also made at these intervals in order to allow for changed performance of each unit. In the embodiment described, only a fraction e.g. 5% of the change is added to the store at each revision so that updating progresses in a more smooth manner than if 100% of the change is added. If such changes exceed a determined amount e.g. 10% of the initial value, an individual or common indicator/alarm 72 may be energized.

Title: An airport runway distance-meter
IPC: G01S1/02
Filed: 1968-12-24
Abstract: 1,203,894. Radio navigation. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. 24 Dec., 1968 [28 Dec., 1967], No. 61317/68. Heading H4D. An airport runway distance-meter which may supplement normal instrument landing system (I.L.S.) facilities provides an indication to an aircraft of its distance along the runway axis from a set point, for example, the theoretical touchdown point. A conventional glidepath transmitter 1, Fig. 1, has a first output which is obtained by summing two signals which are respectively amplitude-modulated at 90Hz and 150Hz, said output including a carrier component, and a second output which is obtained as the difference between the said two signals, and which does not include a carrier component. The first output from the transmitter I is applied directly to an input of an aerial-feeding bridge 4 and the second input from the transmitter 1 is applied through a variable attentuator to a second diametrically opposite input of the bridge 4. The bridge 4 provides two outputs, one representing the sum of the first output and the attenuated second output from the transmitter 1, and the other representing the difference between the first output and the attenuated second output, from the transmitter 1, a 180-degrees phase-shifting loop 41 being connected in one arm of the bridge 4 to obtain the said difference output. An aerial system 2 which is fed by the bridge 4 comprises two parallel horizontal dipoles 21, 22, with reflectors 23, 24, spaced half a wave. length (at the carrier frequency) apart. Alternatively, the aerials may he stacked, with the same spacing. The aerial system (2), Fig. 2 (not shown) is arranged at one side of the runway (5) so that its axis is parallel to the axis (50) of the runway at a distance (d) therefrom, and so that a perpendicular to the axes passing through the centre (G) of the aerial system also passes through the theoretical touch down point (I). The aerial system provides two orthogonal figure-of-eight radiation diagrams centred on the point (G), one representing carrier and cophasal side band signals, and the other representing sideband signals in phase opposition. By suitable adjustment of the attenuator 3, it may be arranged that the difference of depth of modulation (DDM) detected by an aircraft (M) on the axis of the runway is proportional to tan #, where (#) is the angle between the perpendicular to the runway which passes through (G) and (I) and the line joining (M) and (G). The distance of the aircraft from the point (I) is given by d tan #. The DDM may be indicated on the aircraft glide-path receiver, or a separate distance-meter receiver may be carried, working on a different carrier frequency.

Title: Real-time Data Processing System for Processing Time Period Commands
IPC: G06F9/48
Filed: 1978-12-22
Abstract: In real-time data processing systems a process can suspend for an interval of time which it specifies itself by the use of a "Wait For" macroinstruction, the interval taking any value, in defined steps, up to a fixed maximum. All processes which are suspended for the same time interval are chained to each other in a list in the order in which they made their request and to a "timing chain header". The chaining is achieved using forward and backward circular linking through pointers in the process dumpstacks. A timing chain header associated with each list includes (i) the defined interval, (ii) a wake-up time relative to system (real) time, (iii) head and tail list pointers, (iv) a negsum and (v) a timing chain header link. The timing chain headers are linked together starting from a master pointer block which is serviced by an "usherette" process and includes a pointer to the first header of the chain. The timing chain scheme has the following main advantages:- (i) addition and removal of processes from a chain does not require traversal of the chain; (ii) absolute time value adjustment is easily performed by adjusting the interval value of each header; (iii) the system is not in any way constrained by the timing values used.
