Title: Cleaning or degreasing fountain, esp. for metal workpieces - where cleaning liq. is pumped up flexible hose to spraying nozzle or brush
IPC: B08B3/00
Filed: 1980-02-20
Abstract: On top of a tank contg. a cleaning liq. is a bowl provided with an upper, sloping gutter. A compressed air turbine is used to drive a pump, so the liq. travels up a flexible hose fitted with a spraying nozzle, brush, or other cleaning device. The pump uses a bladed impeller, and is located in a tube fixed below the sloping gutter on the bowl. In the base of the bowl is a drain pipe opened or closed by a plug mounted on the end of a hand lever; when the drain pipe is open, liq. collecting in the bowl can flow by gravity back into the tank. Low cost; and only a limited amt. of the cleaning or degreasing liq. (which may be flammable) is exposed to the open air, so the risk of fire is reduced.

Title: Automatic cutting machine for glass panes - where template and electronic memory circuit are used to store programs employed to move scoring tool along complex paths
Inventor: TOMBAL GERARD
IPC: C03B33/04
Filed: 1980-06-13
Abstract: On a frame is a conveyor belt on which a pane rests below a travelling bridge, which can be driven in the longitudinal direction of the conveyor by a motor and spindle. On the bridge is another motor and spindle employed to move a trolley carrying a glass scoring wheel. The two motors are driven by a program stored in a memory, esp. so the scoring wheel can follow a complex path. The scoring wheel can be removed from the trolley and be replaced by a pointer, which can be moved by hand to follow a template while two graduated scales scanned by two photoelectric cells are employed to provide coded data. The data are stored in the memory and then used to move the scoring tool along a prescribed path. Machine is reliable, rapid, and economic and does not require highly skilled workers.

Title: Detachable coupling for microwave generator and cooking cavity - uses insulating sleeve held in place by threaded metal sleeve to enclose coupling antenna between generator and cooking cavity
Inventor: BELLAVOINE ROBERT ALEXIS
IPC: H05B6/72
Filed: 1980-08-28
Abstract: The connection between a microwave generator and the cooking cavity of a microwave oven is through a coupling antenna which passes through a sleeve of a material which is an insulator at microwave frequencies, and is held in place by a threaded metal sleeve coupling which prevents microwave leakage. The walls of the waveguide (3) and the cavity have circular holes (7), and the wave guide hole has an annular ring (8) welded round the edges so the ring projects into the space between waveguide and cavity walls. A long sleeve of insulating material (polytetrafluoroethylene) is fitted inside the annular ring, and the coupling antenna is fitted into an axial hole in the sleeve (9). A threaded metal sleeve fits over the insulating sleeve and is screwed to the outside of the annular ring to trap a ridge on the insulating sleeve. A metal washer fits between the edge of the threaded sleeve and the cooking cavity wall to provide a closed metal seal to prevent leakage of microwaves.

Title: Demountable separator grilles for chest type freezer - uses horizontal grille with wire loops along longitudinal edges to support base of vertical separator with L=shaped end
IPC: F25D23/06
Filed: 1981-01-09
Abstract: The grille for chest type freezers has a horizontal support element with wire loops on two sides to support a vertical separator grille with its lower end bent to an 'L' shape and fitting under the loops in the horizontal support. The horizontal support has rectangular wire loop fixed in the middle of its longitudinal side. These loops are mfd. from an elastically deformable material, allowing the extended wire frame at the base of the vertical separator to be forced under the loops, supporting the vertical separator. This method offers some flexibility in the size of the space between separators and, when not in use, compact storage.

Title: Filter for nuclear plant hot cell gases - has cartridge fixed to pivoting lid forming part of shielding partition
Inventor: FURRER JURGEN
IPC: G21F9/00
Filed: 1981-02-24
Abstract: Filter housing for use in association with a hot cell (24) comprises a filter cartridge (32) for separating radioactive substances from gases, for example for separating radioactive iodine by adsorption on activated charcoal. The cartridge is attached to a pivoting lid (1) for the filter housing, and the lid closes and opens in a horizontal partition wall (22) between two chambers (25,26).

Title: Pressure sensitive adhesive patch to remove wrinkles from skin - is stiff enough to hold skin area tensioned under patch
IPC: A61F13/02
Filed: 1981-06-24
Abstract: An adhesive patch for applying to a wrinkled area of skin in order to eliminate or reduce the wrinkles. The patch is sufficiently rigid to flatten the covered area of the skin, holding it stretched and free from wrinkles. The patch should be flexible enough to conform to the profile of the covered area while retaining its potential to stretch out the wrinkles. The patch is used to reduce or eliminate wrinkles from an area of skin, partic. on the face. The patch is much more effective than creams, lotions, mud packs etc. which have previously been tried. The patch can be made decorative and worn night and day until a wrinkle is smoothed out.

Title: Method of shaping metal articles - uses axially reciprocating punch to push metal in blank between rollers on normal axes
Inventor: CALMETTES LIONEL
IPC: B21K1/74
Filed: 1981-06-30
Abstract: The metal shaping process uses an punch (10) or male tool to drive a blank between rollers (17) collectively constituting a female tool, being of application in the manufacture of polar wheels for vehicle alternators. Shaping is effected by the rollers flattening the blank onto the punch with a controlled reduction in blank thickness. The punch axially reciprocates with a free end configuration matching that required inside the finished work. The rollers are mounted rotatably on a sub-frame (11) with their axes normal to that of the punch. The punch and blank pass between rollers during the drive stroke, the generators of individual rollers matching part of the lateral external profile of the finished work.

Title: Linear electric motor for machine tools - has stator arranged between parallel ferromagnetic strips of stator
Inventor: ARTEMENKO VLADIMIR IVANOVICH
IPC: H02K41/02
Filed: 1981-07-28
Abstract: A linear electric motor, esp. for use in machine tools where a straight-line reciprocating motion and a speed control over a wide range is required, has a stator which is designed as two parallel ferromagnetic strips (1,2) with alternating salient poles (3) and recesses (4), of a length equal to the pole pitch of the motor. A moving core (5) is arranged between the strips and carries a field winding (8) in the middle part which is characterised by a low magnetic permeability. The armature winding (9) is laid in the end parts of the core with a high magnetic permeability and symmetrical to the winding (8). The two coil groups of the winding (9) have an equal number of sections and are electrically connected to a slotted commutator through semiconductor devices between the ends of the sections of the first group and the start of the sections of the second group. The salient poles of the two strips (1,2) are offset against each other by one pole pitch. Such a linear motor has a high efficiency thanks to the low armature winding losses.

Title: Movable stopper for flask - is formed by inner capsule on neck and fixed cap on it
Inventor: ROSE SERGE
IPC: B65D41/04
Filed: 1981-09-09
Abstract: The flask stopper is made of an inner capsule fixed on the neck and an external cap fitted on the capsule. The angular position of the cap relative to the capsule can be assured as the capsule (10) is fixed irreversibly on the neck (2). The cap (20) is fixed, to be movable, on the capsule. The position can be assured relative to the capsule and neck by penetration of an inner chimney part (18) inside the neck. Sealing between the capsule and cap is by a projection (23) inside the flask outlet channel (13).
