Title: Elasticated knitted tape - has an edging portion forming festoons
IPC: D04B21/12
Filed: 1972-04-24
Abstract: An elasticated knitted tape has a body portion including elasticated (e.g. rubber) yarns inserted in zig-zag configuration in the wales and an edging portion which is connected to the body portion at spaced positions by the elasticated yarn passing through the adjacent wale of the body portion. An elasticated yarn is inserted in the edging portion in a zig-zag configuration such that it passes through several (e.g. 3) stitches of the outer wale at the spaced positions and then floats over several (e.g. 2 courses) to the wale adjacent the body portion where it passes through several (e.g. flour) stitches between the spaced positions. When the elasticated yarns are straightened the edging portion separates from the body portion between the spaced positions and form a festoon.

Title: Ceramic insulator sintering plant - with vertical chain conveyor in ultrahigh frequency waveguide after preheating furnace
IPC: H05B6/78
Filed: 1973-10-31
Abstract: Small ceramic insulators for use in sparking plugs of internal combustion engines are sintered by first preheating them to a temp. of approx. 1000 degrees C by applying an electric alternating field or by thermal conduction and radiation. The sintering temp. is then achieved by exposing them to the direct action of an electric field of ultrahigh frequency (UHF). This ensures a very homogenous heating of all articles. The supports on which they rest inside the UHF furnace are safeguarded against excessive heat shocks. The Al2O3 insulators (a) are chared on a belt conveyor (2) to a firing furnace (3) for preheating them to 1000 C. A transfer device (4) loands them to the heat-resistant discs (9) fixed by rods (8) to an endless vertical chain conveyor (6) after they have been covered by a beaker (b). A waveguide (11) of length L2 heats the articles to sintering temp. they are allowed to cool over the length L3 before they are discharged to a conveyor (13). The beakers (b) are transferred to the descending strand of the chain conveyor (6) and to a preheating tube (15) with radiant heating elements. The waveguide (11) is slotted over its full length plates of conductive material at both ends in contact with the other walls produce a system of standing waves of the type most suited to the sintering treatment.

Title: Servo-controlled crane overload protection - has derricking ram pressure detector releasing pressure from servo-controls
IPC: B66C23/90
Filed: 1974-02-14
Abstract: The system is for use with hydraulic cranes having a first actuator, typically a jib derricking ram, and others hydraulically actuated to vary the load on the first one. Fluid pressure in the first actuator is ascertained by a primary detector which opens or shuts at a predetermined pressure, a pressure-reducing connection between an unpressurised union and the servo controls of the other actuators referred to. The pressure-reduction connection can be between the servo fluid reservoir and a pre-control valve connected to the control distributor for the other actuator. Where there are several such, all their pre-control valves can be connected to the primary detector, in each case via a non-return valve.

Title: Fluorescent standby or security lighting - uses AC supply and batteries and has resistive impedance lamp ballast
IPC: H02J9/02
Filed: 1974-04-12
Abstract: The study or security lighting uses fluorescent tubes arranged to work off the normal A.C. supply and, in the event of supply failure, to work in a D.C. mode from a battery supply. The tube is internally primed and uses a resistive ballast preferably in the form of a 110 volt, 60 watt incandescent tube or an equivalent orthodox resistance mounted in series with each fluorescent tube used. An inductance common to the parallel tube arrangement holds the operating voltage at a lower level than is normal in order to increase tube lifetime. It is intended that the duration of operation on D.C. will be insufficient to cause tube polarisation.

Title: Tank gas flow restrictor - has two coaxial valves functioning in opposite directions to relieve pressure
IPC: B60K15/04
Filed: 1974-05-10

The valves can be combined with a component of the tank, such as the filler cap or the vent, and they can have an external sealing ring bearing against the cap. The valve allowing flow out of the tank can be arranged to open at 0.30 Kg, per sq. cm., and the other at 1/30 kg, per sq.cm. The assembly can have upper and lower components with passages, through them, with a component incorporating a central chamber inbetween, to which both passages are connected. The valve itself has one section regulating gas flow into the chamber, and the other one out of it.

Title: Packaging machinery for cylindrical cartridges - consists of devices to orientate, group and position cartridges in package
IPC: B65B35/56
Filed: 1974-05-28
Abstract: Cartridges leaving the end of the production process are arranged in sequence of a rail, supported by their widest part, then dropped through a device which reverses each alternate cartridge, organising them side by side and alternately facing in opposite directions on a support. The row of cartridges is then separated into groups of a required number, and each group is placed as a layer in the package. The package is then moved a distance equal to the thickness of a layer, and the first layer held firm while a second layer is placed on top. After the required number of layers has been added, the package is released and the machinery returns to the starting position.

Title: Paper bag or sack mfr with lengthwise adhesive - to form tube and crosswise, to form bag base
IPC: B31B50/38
Filed: 1974-10-30
Abstract: Paper bags or sacks are manufactured by applying adhesive along one long edge of each layer of paper in a filament, then folding the layer into a flat tube. The adhesive, to form the inner side of the tube, is applied at 90 deg. to the length of the tube and at least partially uninterruptedly to the paper length and, when there are more than one layer, also between the layers. A bag or sack is obtained with a floor adhered together on the inside, when the tube is pressed flat. The floor can be formed at the full speed of bag-making.

The above stabilisation of the trioxane renders it more effective.
Patent FR-2301834-A1 (FR)
Title: Field limiter for astigmatic optical system - comprises thin transparent foil which is used for separating two transparent media to give separate visual fields
IPC: G02B27/22
Filed: 1975-02-21
Abstract: An astigmatic optical system has a separator comprising a thin transparent foil which is of constant thickness. This foil is used to separate two transparent media (21, 22). The refractive index of the separator (Sp) is less than that of the first medium. This stops those light rays which reach the separator with an angle of incidence greater than the limiting angle of total reflection (I) due to the index differential. These rays are therefore unable to pass from the first medium into the second medium. The device therefore constitutes a virtual field limiting screen.

Abstract: The electromagnet (10) and the magnetic reed (6) of the switch are held in close proximity by a support (2). The electromagnet consists of a core (12) and a coil (14), and the support is used also for securing a conductor with a conduct part. At the free end of the reed is provided a thin hinged part (20) at the side facing the core. The contact parts of the reed and conductor are so arranged as to move into contact making and breaking position in accordance with the prevailing magnetic cores. The electromagnet may have a helical shape to facilitate its excitation. The design of the reed switch enables considerable size reduction and load increase.
