Patent GB-1322389-A (GB)
Title: Variable phase clock for recovery of data
IPC: H04L7/00
Filed: 1970-12-23
Abstract: 1322389 Data storage; magnetic discs 23 Dec 1970 [29 Dec 1969] 61075/70 Heading G4C Digital data is recovered from a storage medium (e.g. magnetic discs) by synchronization of clock recovery pulses with data on the tracks. The clock recovery pulses are preferably aligned with the centre of data bit cells. The data has sync. pulses at the start of a group of memory cells and reset pulses at the end of a group and it is desired to use the clock pulses to read out at the middle of each cell in the group. A disc 10 has data storage zones 11 and clock and address track 12 which provide a data pattern source 2 (waveform B) and a reference (clock) source 1 (waveform A) respectively. The reference source has the same frequency as the cells but is shown as e.g. 90 degrees ( period) out of phase which may be due to disc jitter, temperature changes, head skew or head gap variation. A period sensor 4 generates a first analog signal representative of 2¢ times the cell period and phase sensor 3 (Fig. 2, not shown) generates a second analog signal K which represents the phase difference between the reference source and the cells and which is readjusted by each synchronizing pulse. The two analog signals have the same time scale, thus the second signal is proportional to 1 times the cell period. A delay pulse generator 5 (Fig. 3, not shown) generates output clock pulses C in response to trigger pulses from source 1 and the two analog signals. The pulses C feed a data recovery circuit 13 which controls recovery of the data i.e. in this case a time delay of 2¢ minus 1 cell periods is caused and since there is a  period delay in the trigger, the recovery pulses occur 1¢ periods after the start of a cell which is in the middle of a cell as desired. A sequencing circuit 6 controls the operation of the other circuitry and a counter is mentioned comprising two flip-flops.

Title: Multi-Functional Digital Time Displays
IPC: G04G99/00
Filed: 1978-12-08
Abstract: A digital time display presents the minute digits 22 trailing the hour digits during the first half of each hour and leading the hour digits during the second half of each hour, with advancement of the hour digits to the next hour at the end of the first half of each hour. Thus, in Fig. 2 the display shows 18 mins. and 25 secs. past 9, while in Fig. 3 it shows 6 mins. and 9 secs. to 10. The vertical position of the minutes digits may be changed at each quarter hour so that they appear in successive quadrants around the hours digits. As shown it is in fact the hours digits which are displaced, but they may remain central while the other digits are shifted around them. A further embodiment uses 13- element arrays of display elements which are selectively energized to display relatively large hour digits of value 0 to 9, or relatively small minute digits of value 0 to 9 in a relatively upper or a relatively lower position, for the different quarter hours. The display may be of electro- optical or mechanical type and may show minutes and seconds, when used as a chromograph, or the time remaining in a preset interval. <IMAGE>

Patent GB-2020038-A (GB)
Title: Flowmeters
IPC: G01F1/30
Filed: 1979-03-05
Abstract: A flowmeter for particulate solids has a plate (6) inclined to the direction in which a flow of solids impinges on the plate. The plate (6) is supported by one or more cantilevers (12) on each of which strain gauges (16a-d) are located, for the purpose of measuring the difference between the bending moments of each cantilever at spaced apart positions and thereby deducing the magnitude of the horizontal force on the plate, and hence the rate of flow of solids impinging on the plate. The cantilevers may extend vertically. By determining a force rather than a movement of the plate errors due to the flow impinging on different points across the plate are avoided. <IMAGE>

Patent GB-2026976-A (GB)
Title: Process for preparing semipermeable microcapsules
IPC: B01J13/16
Filed: 1979-08-03
Abstract: Semipermeable microcapsules are made by an interfacial polymerization process in which the material to be encapsulated and a hydrophilic monomer are emulsified within a hydrophobic continuous phase and then polymerization is initiated by dissolving a second monomer in the continuous phase. Polymerization occurs only at the interface of the emulsion droplets and results in the formation of macroporous, poorly defined capsule membranes. Next, the affinity of the continuous phase for the hydrophilic monomer is varied by altering the polarity of the continuous phase using a second solvent which is mixed with the continuous phase. By controlling the affinity and the concentration of the second monomer, it is possible to produce microcapsules having uniform capsule membranes and a selected upper limit of permeability. Microcapsules prepared by the process are useful for separating materials of differing molecular weight and for chemical and biological assays.

Title: Making static vanes for gas turbine engines
IPC: B23H9/10
Filed: 1979-11-08
Abstract: Nozzle guide vanes for gas turbine engines have hollow interiors, into which cooling air is pumped, so as to extend the life of the vane whilst operating in a cool environment. A conduit (24) is fitted and cooling air first enters the conduit and then passes through holes (28) and impinges on the inner surface of the vane (24). Where the vane is small, the conduit (24) has to be made from thin material which is difficult to form and perforate. The invention provides a vane 22, the conduit of which is produced in one operation, by chemical etching the developed form from sheet (36, Fig. 4 (not shown)) then bending the sheet to shape. <IMAGE>
