Title: Improvements in or relating to releasable fastening devices for vehicle doors
Inventor: CHANARYN VICTOR
IPC: E05B65/32
Filed: 1958-10-22
Abstract: 875,997. Latches. WILMOT-BREEDEN Ltd. Oct. 15, 1959 [Oct. 22, 1958], No. 33713/58. Class 44. A releasable fastening device, which is adapted to be released directly from outside or remotely from inside the doors on which it is mounted and to be locked from inside the doors to prevent direct release, comprises a longitudinally resilient link 28 which interconnects an internal locking mechanism, comprising lever 26, with an element, such as plate 10, which is displaced during a fastening operation and provides a degree of lost motion there-between in the normal unlocked position, the arrangement being that the link during the fastening operation urges the element from a locked to an unlocked position, the return movement of the element during a latter portion of the fastening operation being accommodated by the lost motion of the spring which is sufficient to allow operation of the locking mechanism without loading the link. As shown, a cam is formed integrally with a cam plate 10, rotation of the latter either by inside operating means, comprising a remote control lever 12, operating on a release area 14, or by a push-button assembly, acting through a lever 17 pivoted at 18 and a release arm 16, causing the fastening device to be released. Rotation of a stem 22 (Fig. 6) either by means of a key turned in a push-button 20 or by an internal locking lever 26 renders the push-button inoperative, the stem then passing through a slot 24 in the lever 17. If lever 26 is moved to its locking position by means of lever 12 when the door is open, then by pressing the push-button as the door is closed the lever 26 remains in its locked position, due to the lost motion of a spring 28 interconnecting the arm and a portion 26b of the locking lever 26. A child safety device which prevents the door being opened from the inside and projects through the free edge of the door comprises a lever 30 (Fig. 2), which in its operative position prevents a pin 34, attached to the lever 12, from upward movement; hence the latch cannot be released by the lever 12. A generally G-shaped keeper is provided with two guides pressed outwardly from the backplate, a lower arc housing a spring-loaded wedge which presses the keeper against an upper guide. The invention is applicable to a rotary toothed cam using a pawl and ratchet arrangement. Specification 871,895 is referred to.

Patent GB-887002-A (GB)
Title: Improvements in or relating to the manufacture of circumferentially corrugated pipes
IPC: B21D15/10
Filed: 1958-10-27
Abstract: 887,002. Making corrugated pipes; stamping. PALMER AERO PRODUCTS Ltd., COOPER, T. H., and GOWARD, S. H. Sept. 9, 1959 [Oct. 27, 1958], No. 34333/58. Classes 83 (2) and 83 (4). A machine for corrugating pipes and tubes in which the pipe or tube is supported on a mandrel and a disc or ring of rubber or like resilient material is compressed and expanded by a pusher to expand the pipe into an annular die cavity surrounding the pipe is characterized by the provision of means for moving the die axially by a distance equal to the pitch of the corrugations and means for applying, during the expansion operation, an endwise force on to the pipe to tend to feed the pipe into the die from the unworked end of the pipe so that the tendency to draw material from a previously formed corrugation during the expansion of the pipe is reduced. The machine comprises a bed 10 supporting at one end a mandrel 12 on a pillar 11 and one or more steadies 14. At the other end of the bed is secured a cylinder block 16 providing two double-acting hydraulic cylinders 17, 18 having their rams 19, 20 in alignment along the bed. The ram 19 is in the form of a sleeve surrounding the ram 20 which constitutes a pusher for compressing and expanding a rubber disc 22 against the end of the mandrel 12. The outer ram 19 engages the free end of the pipe 23 to be corrugated to push the pipe towards the mandrel to prevent the tendency to draw material from a previously formed corrugation during the expansion of the pipe. Clamped to the centre of the bed 10 is a slidable bracket 26 carrying the split die 27, 28 formed internally with two and one-half annular grooves 29. The die is opened and closed by a double-acting hydraulic cylinder 30. An adjustable stop 37 limits the movement of the bracket 26, such movement being effected by a double-acting hydraulic cylinder 36. The end of the pipe projecting from the die is gripped in an hydraulically-operated split clamp. A guide 14 is provided for the pusher ram 20. In operation, the pipe is fitted over the mandrel 12 and the projecting end of the pipe passes through the die and over the pusher, there being a rubber disc 22 located between the pusher and mandrel. The die is closed on to the pipe and the tube is expanded into the innermost groove 29a of the die by compression of the rubber disc to form the first corrugation 41. The pressure on the rubber disc is released and the clamp 40 is closed on the pipe. The die is opened and moved one corrugation along the pipe, whereupon the clamp 40 is released and the die closed, to engage the formed corrugation in the second groove 29b. The die is advanced to the stop 37 carrying the pipe with it after which the next corrugation is formed as hitherto. An hydraulic pump supplies pressure fluid to the ram cylinders via control valves to effect automatic operation of the machine in the proper sequence. A trip device (not shown) may be pre-set to stop the machine after a predetermined number of corrugations have been formed.

Filed: 1961-09-26
Abstract: 955, 741. Photo-electric exposure control. A. C. COUTANT. Sept. 26, 1961 [Sept. 29, 1960], No. 34392/61. Heading G1A. [Also in Divisions G2 and G3] In an automatic control system for an astronomical telescope, photographic camera or cinematographic camera, an attenuating device is interposed between a lens and an observer's eye or a sensitive film and the position of the attenuating device is controlled so as to maintain a predetermined light intensity at the eye or on the film. As shown, Fig.2, a film 9 is exposed through a lens 6 and a rotatable sensitometric wedge 3 in the form of a disc is interposed in the light path to the film. A partially reflecting aluminised mirror 8 is positioned behind the wedge and reflects 20% of the total light passing through the wedge on to resistive type photo-cell 7 the output of which, through a reversing relay 10, controls the energization of a motor 4, coupled through a reducing gear to the wedge 3, to position the wedge so that the light intensity on the film 9 is maintained constant. In a modification, the back of the wedge 3 is aluminised and the plane of the wedge is tilted at 45 degrees, the aluminised surface of the wedge then acting as the mirror 8. In another modification, the mirror 8 is totally reflecting and is small in proportion to the light beam from the lens. In a further modification, Fig. 5, the system is applied to a single lens reflex camera. The light-beam from a lens 6 to a film 9 is interrupted by an inclined rotary shutter 11 having a reflective portion which directs the light from the lens 6 on to a partially transmissive mirror 8 and thence to a viewing lens 12. The light transmitted by the mirror 8 falls on a photocell 7 which controls the motor 4 as described for Fig. 2. A transistor amplifier can be used between the photo-cell and motor. An adjustable vignetted screen can be disposed in front of the photo-cell to compensate for film or shutter-speed.

Title: Improvements in or relating to creasing devices for the production of boxes, cartonsand folders
IPC: B31B50/25
Filed: 1956-11-12
Abstract: 807,251. Creasing. SQUIRE, H. F. May 30, 1957 [Nov. 12, 1956], No. 34571/56. Class 100(2) In a method of producing a creasing matrix on the platen of a cutting and creasing platen press, lengths of channelled strip material are temporarily attached to the creasing rules and caused to adhere to the platen in register with the creasing rules when the press is closed. In Fig. 2 a matrix strip 6 of a flexible material e.g. cellulose acetate or polyvinyl cholride, has a channel 8 in which a location strip 5 of sponge rubber or foamed polystyrene is inserted and gripped. The location strip 5 has a channel 7 of such a width that when it is pushed over one of the creasing rules the strip is temporarily secured thereto. The composite strip 5, 6 is atached to the creasing rule in this way when the press is open and adhesive is applied to the back of the strip 6. The press is then closed until the adhesive is set; when the press is opened again the strip 6 sticks to the surface of the platen in register with the creasing rule. The location strip 5 is then removed from either the strip 6 or the creasing rule. The channel 8 may be engaged by a longitudinal rib on the underside of the location strip 5 if the latter is wider than the channel 8, or the whole of the strip 6 may be carried in a longitudinal groove on the underside of the strip 5. In Fig. 4 the location strip 5 consists of two pieces of foam rubber 10, 11 secured to a linen strip 12, a channel corresponding to the channel 7 being left between them. The channelled matrix strip 6 is fastened to the line strip 12 by a tacky adhesive. A tacky adhesive is also applied to the underside of the strip 6 and is covered by a protective paper strip 13. The composite strip 5, 6 is attached to the creasing rule and the protective strip 13 removed before closing the press. When the press is opened the strip 6 sticks to the platen and the location strip 5 may be carefully removed therefrom. In modifications bosses, longitudinal ribs or other projections on the underside of the strip 5, mating with holes, longitudinal grooves or other recesses on the surface of the strip 6 may replace the tacky adhesive as a means for fastening the two strips together. The linen strip 12 may be omitted, the parts 10, 11 being stuck directly on to to the strip 6. Projections may be formed inside the groove 7 to co-operate with recesses on the creasing blade or vice versa.
