Filed: 1984-02-16
Abstract: A method of covering an open- topped container having a peripheral dependant flange spaced from the container side wall with film comprises: covering the top of the container with a piece of film, the film overlapping the container at its rim; applying vacuum to the underside of the overlapping portion of the film to bring the film into engagement with at least the uppermost part of the rim of the container or to enhance such engagement; applying further vacuum to said overlapping portion to bring the overlapping portion into engagement with the dependent flange of the rim of the container or to enhance such engagement; and then removing surplus film below the free edge of said dependent flange. Apparatus for use in carrying out this method comprises means 7 for holding in position a container to be covered with film; means 10 for positioning a piece of film over the top of the container with the film overlapping the container at its rim; means 17 for applying a vacuum to the underside of the overlapping portion of the film to bring the film into engagement with at least the uppermost part of the rim of the container or to enhance such engagement; further means 15, 16 for applying vacuum to the overlapping portion of the film to bring the overlapping portion into engagement with the dependent flange of the rim of the container or to enhance such engagement; and means 31 for removing surplus film below the free edge of the flange.   <IMAGE>

Title: Hydraulic brake actuator
Inventor: INGRAM BRIAN
IPC: F16D65/22
Filed: 1985-01-16
Abstract: The actuator has a piston 10 and incorporates an automatic adjuster which includes a strut of variable length formed by members 16, 13 threadedly interengaged by way of a non-reversible screw threaded connection. The member 13 is an adjuster shaft which forms a reversible screw threaded connection with a drive ring 23 arranged to control rotation of the adjuster shaft during brake application and release. The non-reversible thread is subject, during brake application, to a load which is the resultant of forces derived from the braking pressure applied to different areas defined respectively by a seal 12 on the piston 10 and a further seal 26. This ensures that random rotation of the adjuster shaft during brake application is resisted. A number of embodiments are illustrated and described. In Fig. 3, nut element 16 coupled to piston 10 forms the non-reversible screw threaded connection with shaft 13 whose end carries seal 26. Figs. 4-6 illustrate alternative embodiments with an intermediate member (10A) associated with piston 10. Actuator may be single acting device utilised in two leading/leading trailing drum brake; it may be double-acting; a wedge actuator; or used in disc brake. <IMAGE>

IPC: E05B63/18
Filed: 1985-05-02
Abstract: A multi point door locking mechanism particularly suitable for a patio door comprises a pin bar (6) which is slidably movable by means of a locking device. The bar (6) is mounted to one panel (2) of the door and a cooperating keep plate (22) with a keyhole-shaped slot is mounted on the facing edge of the other panel (4) of the door.

Title: Bipolar semiconductor device
Inventor: HUANG EDDIE
IPC: H01L29/36
Filed: 1985-05-15
Abstract: The carrier concentration 30 of the base region has a humped profile with a maximum 35 within the bulk of the base region and separated from the p-n junctions 32 and 34 with the emitter and collector regions of the device. The humped profile may be provided by either the partial compensation of the dopant characteristic of the required a conductivity type of the base region by dopant characteristic of the opposite conductivity type or by the reverse diffusion of dopant characteristic of the required conductivity type of the base region from the surface of the semiconductor body. The humped profile renders the average resistivity of the base region substantially independent of the position of the emitter region-base region junction which is of particular advantage in the manufacture of gate turn-off thyristors and transistors which have shallow (0.5 to 5 micron depth) emitter regions. <IMAGE>

Title: Solderable contact materials
Inventor: ELY BRIAN WILLIAM
IPC: C03C27/04
Filed: 1985-07-12
Abstract: It is often required to solder an electrical connection to a component or a lead thereto via a contact pad.At present pads are commonly of materials that tend to oxidise during any subsequent heat processing of the device, and are then difficult to solder. It has now been discovered that certain alloys of copper containing manganese may be used to construct contact pads that are both solderable and remain so even when ovened in air at 200 DEG C, and the invention provides a method of constructing solderable contact pads upon a chosen substrate, in which method there is formed on the relevant area of the substrate a layer of such a manganese/copper alloy.

Title: Apparatus for applying surgical clips
Inventor: GREEN DAVID T
IPC: A61B17/115
Filed: 1985-06-24
Abstract: 57 Surgical clip applying apparatus in which clips are delivered to a pair of jaws one at a time for closure around body tissue. The squeezing together of a pair of ring handles causes the jaws to move distally relative to the apparatus. The jaws contact a pair of inclined surfaces on the shaft of the apparatus and are thereby forced together, causing the distal-most clip in a linear array to be closed around body tissue. Release of the handles returns the jaws to the original positions so that another clip closing cycle can be initiated. An escapement mechanism interacts with the jaws to ensure that only one clip at a time from the linear array is delivered to the jaws. A clutch assembly ensures that each step in the clip closing and return cycle is completed in the proper sequence.

Title: Method and circuit arrangement for controlling an anti-lock and anti-spin wheel brake system for automotive vehicles with all-wheel drive
Inventor: FENNEL HELMUT
IPC: B60T8/70
Filed: 1986-06-13
Abstract: In a method for controlling an anti-lock brake system which is destined for automotive vehicles with all-wheel drive, electric signals representative of the rotational behaviour of the wheels are generated and logically combined. Upon the occurrence of a tendency to lock, the braking pressure will be modulated, to which effect the instantaneous wheel slip, wheel acceleration and wheel deceleration are evaluated as control criteria and the individual wheel speed (vR) is compared in each case with a vehicle reference speed (vREF) which serves as a reference value for the modulation of braking pressure. In the event of a wheel rotational behaviour that is typical of spinning, eg acceleration above a set value, and that shows in the rise of the vehicle reference speed (vREF) in excess of the actual vehicle speed (vFZG), the control concept employed is modified until a specific point of time by leaving the instantaneous wheel slip as a control criterion out of account for this phase of spinning and by the wheel slip control becoming dependent on solely wheel acceleration or wheel deceleration. <IMAGE>
