Title: A Process for the Preparation of a Sterile Injectable Physiologically Acceptable Solution of an X-ray Contrast Agent and Solutions of the X-ray Contrast Agent and a Buffer
IPC: A61K49/04
Filed: 1979-07-04
Abstract: Sterile, injectable, physiologically acceptable solutions of an X-ray contrast agent are prepared by autoclaving a solution of a m- carboxamido-o-iodo-N-( beta - hydroxyalkyl)aniline X-ray contrast agent in the presence of a physiologically acceptable buffer system the pH of which decreases with increasing temperature. The presence of a temperature dependent buffer, preferably an amine, enables X-ray contrast agents to be sterilized by autoclaving without significant decomposition. Examples of the autoclaving processes are given and solutions for autoclaving containing a m- carboxamido-o-iodo-N-( beta - hydroxyalkyl)aniline X-ray contrast agent and a physiologically acceptable buffer system the pH of which decreases with increasing temperature are described and claimed.

Title: Engine fuel supply and storage systems
IPC: B60K15/06
Filed: 1981-04-16
Abstract: A first fuel tank 1 contains a level detector 13 and is connected by a pipe 5 to an engine fuel pump 4. A second tank 2 has a number of outlets controlled by float valves 8 leading through a one- way valve 7 to the tank 1.

Title: Semiconductor gas sensor
IPC: G01N27/12
Filed: 1981-09-24
Abstract: A Semiconductor gas sensor comprises an insulating substrate (11) on which a resistive heater track (15) coupled to a pair of electrodes (12, 14) is deposited. A film (16) of a semiconductive metal oxide, typically a doped oxide, is ion-plated on to the assembly so as to contact the resistive track (15) and a further electrode (13). Exposure of the device to a particular gas, e.g. hydrogen sulphide, reduces the resistivity of the semiconductive film (16), this change being detected via an amplifier circuit (not shown). In an alternative version of the sensor (Figures 5a, 5b and 6) the heater is disposed under a dielectric layer, the semiconductive film being ion-plated onto the dielectric layer and electrodes therein. <IMAGE>

Abstract: A packing (10) e.g. for use in cooling towers is built up of mutually spaced membranes (12, 14) forming ducts for the passage of a fluid introduced at the top of the packing and collected in a trough or channels below the membranes. In order to be able to collect the liquid passing through the packing immediately beneath the lower surface of the latter, thereby reducing the pumping height without appreciably affecting the flow conditions of the air passing through the packing, the packing (10) is provided with surfaces to carry off the liquid which are inclined at an angle relative to the horizontal and are connected to at least one collecting channel or trough (16), these surfaces serving to carry the liquid passing out of the packing into the collecting channel. The membranes may be made of metal or plastic. <IMAGE>

Abstract: A holder for an anti-glare screen (13) which in use holds the anti-glare screen over the screen (10) of a visual display unit (VDU), and which further facilitates removal and replacement of the anti-glare screen (13). The holder (8) comprises a frame (9) having along at least one edge thereof a channel (12) into, and out of which, the anti- glare screen (13) may be slid to be releaseably received and held, and means (14) for securing the frame (9) directly to, or to the surround of, the screen (10) of the VDU. The anti-glare screen (10) comprises a sheet of anti-glare material (monofilament micromesh) sandwiched between two sheets or rigid material which provide a frame for the anti-glare screen. To protect the sheet of anti-glare material prior to the anti-glare screen (10) being used the two sheets of rigid material are each divided into a central portion and an outer portion the outer portion of which forms the frame and the central portion of which is removable to disclose the anti-glare material thereunder. <IMAGE>

Title: An electrical domestic appliance provided with a lockable door and an electrical switch
IPC: D06F37/42
Filed: 1982-03-03
Abstract: An electrical domestic appliance (e.g. washing machine) is provided with a door 1 that can be locked and an electrical switch 5. The door-lock (14, 15, fig 1A, not shown) and the switch 5 are separately operable, the lock being latched in the locked position when the switch is "on" while the door is closed and the switch being locked in the "off" position when the lock is disengaged. The lock has a transmission element 10 against which a lock releasing button 7 pushes, said transmission element 10 being moved out of the actuating path of the button 7 by the switch 5 when the switch is in its "on" position as shown in fig 4. When the switch is in its "off" position (fig. 3) the button 7 may engage the transmission element 10 to release the lock at the same time moving the abutment 17 opposite a housing part 18 and thereby preventing operation of the switch 5 by a latching effect due to a tab 21 of a slide 19. <IMAGE>
Patent GB-2097561-A (GB)
Title: Non-destructive testing apparatus
IPC: G01B5/00
Filed: 1982-04-22
Abstract: The invention relates to non- destructive testing apparatus, particularly the control of the relative positions of one or more test probes and the test piece. In order to avoid the errors that frequently occur by changes in the clearance between the testing apparatus and the test material resulting from movement of the test material and/or surface irregularities in the test piece, the invention proposes a method of controlling the relative positions of test probes (6) and test piece in which lateral movements of the test piece from its path through the testing apparatus are detected by sensors (2) and the position of the test probes is adjusted in response thereto. In this way, the clearance between the test probe or probes and the test piece can be maintained within predetermined tolerances. <IMAGE>
