Title: Method and apparatus for making dental prostheses
Inventor: FELBER WILFRIED
IPC: A61C13/14
Filed: 1983-04-20
Abstract: To provide for simple and errorproof mixing of materials for pressure injection moulding of dentures of other dental prostheses, a liquid and powder mixture of methyl- methacrylate base plastic is intimately mixed to form an essentially bubble-free mixture which is poured into an injection vessel 2, permitted to swell, and then injected under predetermined pressure, within a narrow tolerance range, into a plaster mould retained within separable halves 301, 302, of an injection mould 3. The process is automatically controlled by a sequencing control unit 8, for example a micro- processor unit, which applies first closing pressure to the mould halves by a pressure element 4, and then injection pressure by a piston-cylinder unit 1, after a suitable swelling period has elapsed. Preferably, the pressures are applied hydraulically and the pressures are monitored by a pressure sensor 6 which, through the control unit 8 controls a pump P for maintenance of the requisite pressure. <IMAGE>

Title: Method of filling cans with substantially non-carbonated drinks
Inventor: KIKUCHI YASUSHI
IPC: B65B31/00
Filed: 1983-10-31
Abstract: Non-carbonated drinks are filled into thin-walled drawn aluminium cans which tend to collapse when they are not pressurised, by a method which comprises dissolving N2 gas and CO2 gas under pressure in a non-carbonated drink in a saturator 4, the weight ratio of the CO2 gas to the drink being 15/10,000 or less; filling this drink into the cans in a filling machine 11 at the same temperature and pressure as the saturator 4, spraying N2 or CO2 gas-containing inert gas upon the upper surface of the drink in the cans while the drink is exposed to the atmosphere and then seaming the cans in a machine 12. The conditions under which the CO2 and N2 gases are dissolved in the drink, i.e. temperature, pressure, and CO2 to N2 ratio, are selected by reference to a series of can-internal pressure/ temperature curves (Fig. 2), so that the can internal pressure after filling and seaming have been completed falls within the predetermined strength range of the cans and therefore that the cans are not burst by excessive internal pressure during pasteurising and do not collapse inwards at the lower drinking temperature when handled. <IMAGE>

Title: Device for automatically inserting transverse elements between containers which advance side-by-side in at least one row
Inventor: PALLOTTI ANTONIO
IPC: B65B61/20
Filed: 1983-11-30
Abstract: In order to allow the automatic insertion of transverse divider elements between containers, such as bottles, cans and the like, which advance side-by-side in at least one row, a device is proposed which comprises above the moving containers an automatic divider element distributor 15 and below the containers means for temporarily spacing the containers apart to create the space necessary for inserting the divider elements. These means are constituted by a series of pegs 25 which are made to move, et the same linear speed as the containers, along an endless path comprising a branch, part of which slopes upwards during which the pegs are inserted between the containers, and part of which is parallel to the container advancement direction, during which the pegs accompany the containers, said branch being connected to a return branch by way of a substantially semi- circular portion lying directly below the distributor 15 and in which the tips of the pegs space the containers apart because of the difference between the path taken by the tips of the pegs and the path taken by their base. <IMAGE>
Patent GB-2133899-A (GB)
Title: Improved imaging system
Inventor: SANDERS FREDERICK W
IPC: G03F7/00
Filed: 1984-01-17
Abstract: Means are provided for preventing image diffusion in images formed by imagewise exposure of a microencapsulated photosensitive material to actinic radiation, followed by a color forming reaction between a chromogenic material and a developer. A curing agent for the photosensitive composition, such as an organic peroxide, is microencapsulated separately from the photosensitive material and included in the coating. When the capsules are ruptured, the released curing agent reacts with the photosensitive material and thereby stabilizes the formed color so that its quality will not deteriorate over time.

Patent GB-2148651-A (GB)
Title: Doppler speed measurement
Inventor: CROSS MALCOLM GEOFFREY
IPC: G01S13/60
Filed: 1984-09-14
Abstract: In a doppler radar velocity measurement device the received signal is divided into two channels. In the first channel there is a dispersive delay i.e. one which delay delays higher frequencies more slope- than lower frequencies whose characteristics are such, for a nominal aircraft velocity, the frequency versus time characteristics of the received signal are inverted (i.e. the frequency versus time graph of Fig. 1 becomes the graph  gamma ). The other channel has a matching delay 3 which is non-dispersive. By comparing the signal envelope and hence (due to Gaussian filter 1) the signal frequency in the two channels over a period of time, a measure is obtained of the difference between the actual velocity and the assumed nominal velocity, since this is related to the value of the rate of change of Doppler Shift with time. A digital implementation is also described. <IMAGE>

Title: Improvements in clutch release mechanisms
Inventor: HAYWARD CHARLES K
IPC: F16D23/14
Filed: 1984-11-02
Abstract: A clutch-release mechanism M has a bearing assembly 10, 12, 13 of which an outer ring 10 contacts a clutch release component and an inner ring 12 receives thrust force from a clutch actuator via a hub 17. A chamber 24 containing air is defined between the outer ring 12 and a casing 16 and changes shape when the bearing assembly is displaced radially to ensure alignment between the mechanism M and the clutch axis. Seals 15 extend between the rings 10, 12 and have lips 20 which make sliding contact with opposed surfaces S, T of the casing 16 and the hub 17. These lips 20 provide a resilient outward expansive force controlling the radial displacement of the bearing assembly. <IMAGE>

IPC: C07D205/09
Filed: 1985-11-18
Abstract: <IMAGE> 2-Thiacephems II (R1=H or an organic group, R2=H or a carboxy protecting group and Y=H, halogen or an organic group) are prepared from azetidinones IV   <IMAGE> (R1, R2 as above and Z represents various organic groups) by ozonolysis of the double bond, conversion of the hydroxy group to a halogen atom, an alkane sulphonyloxy group or an arene sulphonyloxy group, and cyclisation by reaction with a sulphide or hydrosulphide in the presence of a base to give II (Y=H). Halogenation, preferably after cyclisation, using N-bromosuccinimide or N-chlorosuccinimide in an inert organic solvent at 20-130 DEG C in the presence of a radical initiator and an acid scavenger, gives II (Y=halogen). The latter compounds may be converted to II (Y=organic group) by known reactions. The 2-thiacephems II are useful in the preparation of penems as described in Application No. 2131432, from which this Application is divided.
