Title: Analog-to-digital converter
IPC: H03M1/10
Filed: 1979-09-24
Abstract: An analog-to-digital converter is supervised by a microprocessor 16 and includes means for digitally compensating for initial gain and offset errors and gain and offset drift errors due to temperature variations. An analog input voltage is applied to the analog-to-digital converter 4, the output of which is both stored in the microprocessor 16 and applied to a linear digital-to-analog converter 6. The output of the linear converter is summed with the original analog input voltage and the difference applied to the analog-to-digital converter as an unknown input signal. This process is continued to achieve a desired resolution. The output of a differential temperature sensor 14 is similarly processed to determine the proper amount of compensation for gain and offset drift. The microprocessor provides both control and computation capabilities. <IMAGE>

Patent GB-2049147-A (GB)
Title: Spine fin tube heat exchangers
IPC: F28F1/36
Filed: 1980-02-13
Abstract: A spine fin tube heat exchanger wherein the density of spine fins (11) is greater along portions of passes of tube (10) within a pattern (33) of high flow of air or the like across the heat exchanger. Those portions of the tubing at the bends (12 to 18) and outside the pattern (33) are formed with a lower density of spine fins (11). Such lower density outside the pattern (33) and at the bends does not materially reduce the overall heat exchange capacity of the heat exchanger, and results in a heat exchanger where less material and time are required to form the heat exchanger without any significant loss in its capacity. The fins are preferably applied to the tube by changing the rate of feed of the tube (10) as it feeds through a head wrapping said tube with spine fins, in order to increase the amount of stretch of the spine fin strip along the zones of low density compared to the amount of stretch in the strip along the zone of high density. Consequently, the same mount of material is required for each wrap along both kinds of zones. <IMAGE>

Title: Safety latch for appliance door
IPC: E05B47/00
Filed: 1980-04-17
Abstract: An appliance for cleaning and treating clothes has a housing, a door 4 and a latch for the door. The latch includes means for impeding access to a handle portion 7 for the door, a latch means 8 for releasably securing the door shut and means 22 for locking the catch means. The impediment can be manually overcome to gain access to the handle when the catch is unlocked. When the catch means is locked, overcoming the impediment to gain effective handle access is prevented. In the example shown the position of the handle 7 itself constitutes an impediment in the position (Fig. 5) in which the catch is locked since space 42 will not allow the handle to be grasped. In the unlocked position (Fig. 6) the catch is moved to the left as the catch is disengaged and the space 42 becomes wide enough for the handle to be grasped. <IMAGE>

Title: Manufacture of colour developing sheets
IPC: B41M5/155
Filed: 1980-05-02
Abstract: Potassium hydroxide or another alkaline potassium compound is used to adjust the pH of an aqueous colour developing clay coating composition in the manufacture of colour developing material for use in pressure-sensitive or similar copying systems. This reduces the decline in reactivity with time of such material and increases initial print intensity compared with conventional material in which the corresponding sodium compound is used for pH adjustment. Especially good results are obtained where the material being coated is a paper of high acidity such as results from rosin/alum sizing.

Patent GB-2081891-A (GB)
Title: Web monitoring apparatus
IPC: B65H26/02
Filed: 1980-08-11
Abstract: For detecting holes and inclusions in a longitudinally-moving web (10), e.g. paper, cameras (22a, b and c) containing line arrays (24) of photodiodes are imaged transversely across respective portions of the web. Each array is repetitively scanned to provide video signals which are digitised and sequentially stored in a memory addressed in synchronisation with the scanning. Arithmetic circuitry subtracts the fresh digital value for a given photodiode from the stored value for that diode from the previous scan and signals a defect if the difference exceeds set limits. Logic circuitry controlled by the sign of the difference distinguishes a hole from an inclusion. The fresh value is then entered in the memory to serve as a reference for that diode on the next scan. Further circuitry responds to hole signals from the camera viewing the middle portion of the web to indicate when the web is irregular or absent, and counts and indicates holes and inclusions. <IMAGE>
