Title: Pressure sealed electrical connecting device
IPC: H01B17/30
Filed: 1966-11-14
Abstract: 1,119,926. Terminals; carrying conductors through partitions. WINSCO INSTRUMENTS & CONTROLS CO. Inc. 14 Nov., 1966 [1 Dec., 1965], No. 50922/66. Heading H2E. A pressure sealed connecting device comprises a header member 12 in threaded engagement with an opening 11 in a bulkhead 10 subjected to high pressure on one side and a lower pressure on the other, the header member having a bore 16 which has an enlarged diameter portion 17 to define a shoulder 18 facing the high pressure side of the connector, the latter further comprising a sleeve of plastics material, preferably trifluorochloroethylene polymer, in sealing engagement with the bore 16 and having an enlarged portion 20 which seats against shoulder 18. A conducting pin 22 passes through the sleeve and has an enlarged portion 23 at one end which seats against the end surface of enlarged portion 20. An O-ring provides a seal between the bulkhead 10 and enlarged portion 14 of the header member 12. The pin 22 is soldered at 27 to a conductor 28, the joint being enclosed in epoxy resin 12b filling a counterbored portion 12a of member 12, and at 25 to a conductor 26, the enlarged portion 23 of pin 22 and the junction 25 having a covering 29 of Neoprene. In a modification the pin itself (39, Fig. 2, not shown) has an axial bore containing another sleeve and pin designed to have annular surfaces as at 18 and 24 in Fig. 1 to provide fluid-tight seals, the outer pin being connected to the outer members of coaxial cables on opposite sides of the bulkhead 10 and the inner pin being connected to the inner members of the same coaxial cables. In a further modification, the member 12 is provided with several bores (Fig. 3, not shown) to enable several conducting leads to be taken through one opening in the bulkhead.

Title: A method of making a magnetizable web
IPC: C09D5/23
Filed: 1965-12-02
Abstract: A magnetic layer is formed by coating a mixture of polymer solution, polymerizable monomer catalyst, and magnetic material on to a mould, polymerizing the monomer, and then stripping the coating from the mould.  The constituents of the mixture may be P.V.C., 1,3-butylene dimethacrylate, t-butyl perbenzoate, and acicular g -Fe2O3 resp. with 1,1,1-trichloroethan as solvent.  The mixture may include plasticizers, e.g. dioctyl phthalate, and heat stabilizers, e.g. Ba-Cd Zn, for the polymer; a wetting agent for the Fe2O3, e.g. diethylene glycol monolaurate; and a thixotropic agent to prevent settling, e.g. colloidal S1O2, or carbon black.  In the example, a mixture containing the Fe2O3 was thinned with a mixture containing P.V.C., the monomer being present in both, and was sprayed on to the inner surface of a cylindrical steel mould, which may initially have been coated with a silicone, e.g. dimethylpolysiloxane. A further mixture containing P.V.C., and a non-acrylic monomer, was sprayed over the first layer (to form the base).  The mould was then heated at 370 DEG  F. and the layers stripped from the mould.

Title: Container with venting gasket
IPC: F04B9/14
Filed: 1970-10-29
Abstract: 1306615 Reciprocating dispensing pumps DIAMOND INTERNATIONAL CORP 29 Dec 1970 [8 Jan 1970] 61517/70 Heading F1A In a hand actuated liquid dispensing pump D mounted on a container 10, a polyethylene or rubber gasket-diaphragm valve 38 is clamped in sealing fashion between the top of the container 10 and a screwed cap 16 and has a downwardly converging tapered frustro-conical flexible lip 38b encircling the pump cylinder 20 in radial sealing engagement therewith below an air vent 36, the seal acting only in one direction to allow air intake for pressure balance with the atmosphere but automatically closing against liquid &c. discharge from the container whereby the container interior pressure is automatically maintained equalized with the atmosphere during long periods of inactivity such as during shipment, and additionally, loss of liquid or blocking of the air vent is avoided when the container is tilted in use. Thus sealing arrangement prevents unsightly distortion or collapse of the container, when formed from a non-rigid material such as plastics for example, normally resulting from unequalized pressures between the container interior and atmosphere. In Fig. 4 (not shown) the seal lip engages the pump cylinder at a point above the air vent 36 whereby the seal simply serves to admit air into the container quite independently of the pump when there is imbalance of pressures.

Abstract: 1,235,477. Trimming veneer. ENGLISH ROSE KITCHENS Ltd. 25 Nov., 1968 [23 Aug., 1967], No. 55992/68. Divided out of 1,235,476. Heading B5L. A machine for trimming the edges and ends of oversize veneer strips bonded to the edge faces of rectangular panels comprises a conveyer 11 to carry and transport the panels, end cutter means adapted to traverse end corners of each panel whilst the latter is held stationary upon the conveyer, edge cutter means adapted to traverse longitudinal edges of each panel whilst the latter is fed past them on the conveyer, and control means adapted to synchronize operation of each cutter means with the operation of the conveyer. In the machine described a roller track 65 raised by air cylinders 66, 67, Fig. 3, receives a panel 33<SP>1</SP> and is then lowered to deposit the panel on to conveyer 11 where it is held in position by pressure pads 45, 46 actuated by air cylinders 47, 48. Whilst the panel was fed on to track 65 it caused the rotary cutter heads of end trimming devices 24, Fig. 2, to be set in motion. Once the panel is clamped in position the cutter devices are pivoted about a horizontal axis so that the cutter heads thereof describe an arcuate path to trim the ends of the veneer. Pivoting of the devices 24 is effected by an air cylinder 36 operation of which causes rotation of a shaft 27 on which the devices 24 are mounted by arms 25. The arms 25 are pivoted to allow the cutter heads of the devices 24 to be urged against the ends of the panel by a spring 30. After return of the devices 24 to their original position and release of the pressure pads 45, 46 the conveyer is actuated to carry the panel past the rotary cutter heads 60, Fig. 5, of cutting devices mounted on swing arms 52. The cutting devices are spring-urged into contact with the upper and lower marginal edges of the panel edge faces and trim excess veneer therefrom as the panel advances.
