Title: Armature member assembly for a clutch-brake unit
Inventor: BRINKMANN KARL ERNST
IPC: F16D67/06
Filed: 1984-09-05
Abstract: A retaining member (13) of an armature member assembly (10) is fixed to a shaft (16) of a clutch-brake unit (17). The assembly (10) is equipped with two armature plates (11 and 12). These can be moved relative to the retaining member (13), in the direction away from the member (13) by virtue of leaf springs (14 and 15) of annular or polygonal shape. The minimum distance between the armature plates (11 and 12) is established by spacers (20). Since both armature plates (11 and 12) can be moved away from the retaining member (13) independently of one another, it is possible e.g. for the armature plate (11) to be attracted to the clutch (22) before the armature plate (12) is released from the brake (24). The result is not only that switching is very rapid but also that there is less switching noise because the weights moved in the switching process are reduced. <IMAGE>

Title: Anaesthetic gas apparatus
Inventor: SWANN GERALD
IPC: A61M16/10
Filed: 1985-06-03
Abstract: A self-latching gas valve 17 suitable for use as a general anaesthesia selector in apparatus for controlling the supply of gaseous anaesthetic and oxygen to a medical or dental patient comprises a plunger 22 manually depressible against a spring bias 23 to close a passage between a gas inlet 24 and a gas outlet 26, and a latch 33 operable by gas pressure at the gas inlet to latch the plunger in the closed position, such that removal of pressure at the inlet causes the latch to release the plunger to be returned by the spring bias to the open position thereof. Where the apparatus comprises an oxygen by-pass to maintain a minimum flow of oxygen to the patient, the valve is included in the by-pass to close off the minimum supply when rapid general anaesthesia is to be achieved, the self-latching facility ensuring that, when the apparatus is used again after having been shut down, the oxygen by-pass has been re-opened by the removal of inlet oxygen pressure during the shut down period. A control valve for the vaporiser is also described and claimed, Figs 3 & 4, not shown. <IMAGE>

Title: Gas discharge laser apparatus
Inventor: WHEATLEY DAVID IAN
IPC: H01S3/038
Filed: 1987-11-13
Abstract: A first discharge electrode of a laser comprises a number of separate conductive portions (12) located adjacent to one another within the laser envelope (10), whilst a second discharge electrode (14) is provided within the envelope spaced apart from the first discharge electrode. A power source (15) applies a voltage between the first and second discharge electrodes so that a current may flow between them through the gas. Switching means (16) connect the conductive portions (12) of the first electrode to the power source (15) in sequence so that the discharge current flows between the second electrode (14) and the energised portion of the first electrode (12). Each conductive portion of the first electrode may be connected to the power supply via a common ballast component. The switching means may operate so that one conductive portion of the first electrode is permanently connected to the power source, the remaining portions being connected in succession. The apparatus ensures uniform flow discharge with a single ballast component. <IMAGE>

Title: Image line rearrangement gives vdu security
Inventor: MAITLAND ARTHUR
IPC: G06F21/84
Filed: 1989-01-14
Abstract: An electronic security system for protecting visual display units (VDU's) and personal computers against remote electromagnetic surveillance of data displayed on cathode ray tubes (CRT's) operates by scrambling the scanning pattern of the CRT (26') such that it is scanned in a non-consecutive manner. A random sequence generator (36) scrambles the order in which data is read from the video RAM (12') of a VDU and a digital to analogue convertor (30) controls the scanning pattern of the CRT (26') such that the data output from the video RAM (12') is displayed on the CRT (26') at the correct position whilst the CRT (26') is scanned in a non-consecutive order. In the described embodiment complete horizontal lines are scanned in a random order, however the system could be adapted to scramble the order of vertical columns, portions of rows or columns, or individual pixels. In order to hinder decryption, the scanning order can be changed at random or periodic intervals, or whenever the displayed data is altered significantly.

Title: Potassium nitrate
Inventor: PORTELA LOUIS SOBRINO
IPC: C01D9/04
Filed: 1989-04-13
Abstract: Initially, a reaction stage is carried out in which the potassium chloride is put into contact with a solution of dilute nitric acid coming from a stage of recovery of the acid by re-extraction and with a solution of concentrated nitric acid, all the potassium chloride supplied being thus dissolved and avoiding any crystallization of the potassium nitrate formed in order to, subsequently, carry out a stage of separation of the insoluble impurities which accompany the potassium chloride from the reaction mixture obtained, leaving this completely clarified and free from solids. With these improvements complete separation of the insoluble impurities of the potassium chloride can be carried out immediately after the reaction stage thus producing a white potassium nitrate of high purity.
