Title: Safety switch for ice making machine - immersion electrode stops ice formation when ice slurry reduces flow
IPC: F25C1/06
Filed: 1973-11-29
Abstract: An ice making machine in which water from a tank (6) is forced through a jacketted coil (1) by a pump (3) while a refrigerant is passed through the jacket (4) until an icy slurry is formed, and in which the slurry is ejected from the coil when another gas (CALORIGENE R. T. M.) is pumped through the jacket, includes a special switch to avoid choking the tube and pump due to hardening of the ice to too great a degree. A large electrode (8) immersed in the ice receiver tank (5) is connected electrically with a small electrode (10) housed inside a tube (11) through which flows a small quantity of the water. When the flow reaches a minimum permitted quantity as the ice forms, the level inside the receiver (5) falls, the large electrode (8) is no longer immersed and the circuit is switch to prevent further ice formation.

Title: Underwater harpoon gun elastic band connector - ball joint allows freedom of angular movement of arms of V-shaped wire
IPC: F41B7/04
Filed: 1974-05-24
Abstract: The underwater harpoon gun, powered by an elastic band, has a V-shaped wire connecting the two ends of the elastic band, which engages the end of the harpoon or arrow, and which tends to be stretched straight under tension, and spring open after firing, resulting in wear at the connecting points. In its tensioned position, the end of this connector (1) is retained inside the housing (5) by a spherical block (3), the end (2) of the connector being bent over. Thus the ends of the connector are attached to the ends of the elastic by ball joints which allow the angle between them to vary with the tension. The hole through this block can be round, oval or X-shaped.

Title: Reversible storage of data on insulator layer - with bombardment of electrons for writing reading and erasing operations
IPC: G11C7/00
Filed: 1974-12-09
Abstract: Data is stored in a thin insulator layer provided as a storage medium and placed on a conductive carrier. For recording purposes the medium is bombarded with electrons of one energy. The data is read by means of electrons of another energy and the data is erased by means of electrons of the first energy. An electron-collecting zone located in front of the insulator layer in the recording and reading operations can be disconnected. Access during the reading, recording and erasing operations can take place at will. Good insulator layers as a storage medium enable data storage to be carried out at room temperature over a long period.

Title: Reinforced concrete fire escape - with variable tread width on straight and turning sections and is independent of building
IPC: E04F11/02
Filed: 1975-02-03
Abstract: The fire-escape is a structure inside the building, but completely independent of it, thus allowing more time for the inhabitants to escape in the event of fire. The escape consists of a reinforced concrete pallet, the shuttering for which uses a series of flat panels. Within the space between panels are brackets which support the pallet and in the gaps are placed both normal and emergency lighting points. Individual steps are attached to a stringer. The fire-escape is constructed so that, whatever the size and width of its well-hole, the lay-out of the steps at points where the escape changes direction, allows a good tread while still keeping the widths acceptable limits, the balancing of the straight and turning areas being determined by calculation.

Title: Side coupled forage harvester and unloading trailer - with cutter driven from trailer bed belt drive and automatic coupling devices
IPC: A01D90/12
Filed: 1975-03-06
Abstract: The assembly consists of a side delivery trailer towed and powered by a tractor and provided with a transverse conveyor belt driven from the tractor. A forage harvester is coupled to the side of the trailer, cutting the crop and loading the trailer, the cutter being driven by a shaft from a gear box on the trailer and through a belt and a pulley. The trailer bed is movable and is driven by a pump and a motor. The two link arms on the harvester end in a special automatic locking and release catches. By these means the trailer is automatically coupled to the harvester which cuts the crop and fills the trailer. The latter is then automatically uncoupled from the harvester and is driven to the stockyard where it unloads.

Title: Hot-dip galvanising tank - for strip and wire with thermodynamic circulation of molten lead in pan jacket
IPC: C23C2/00
Filed: 1975-04-25
Abstract: A hot-dip galvanizing system for wire and strip has a double-walled steel pan for the molten zinc, inserted in an oven with burners and flues. The space between inner and outer wall is filled with a liquid inactive heat transport medium (molten lead).

Title: Night storage heater temperature controller - switches from storage to direct heating when high tariff period starts
IPC: G05D23/275
Filed: 1976-01-22
Abstract: A temperature controller for a high storage heater, and reacting to room temperature, uses a thermoswitch to control the charge and discharge of thermal energy. A relay (9) switches the heating resistance from high to low tariff. The relay has a second pair of contacts (17, 18) in series with its first pair of contacts (11) (tariff changeover contacts). At the start of the high tariff period, the current to the heating resistance (5) is interrupted and transferred to an element (20) that heats the room directly. At the end of the high tariff period the contacts switch back to storage.

Title: Vehicle windscreen wiper arm drive - has rotary crank fitting in slot in toothed drive segment permitting adjustment of sweep
IPC: B60S1/18
Filed: 1976-02-24
Abstract: A drive for a vehicle windscreen wiper (2) includes a toothed segment (9) which is swung to and for, swinging about a bottom pivot pin (10). This drives a toothed pinion (3) attached to a spindle (1) carrying the wiper arm (2). The segment is driven by a cranked arm (7) mounted on the output spindle (6) of the drive motor (12) at the rear. The crank arm (7) has a leg (8) projecting from it, which travels in a slot (9) in the segment, thus producing the reciprocation as the arm (7) rotates. By varying the distance between the centre of the leg (8) and the centre of the motor spindle (6), the angle of swing of the wiper can be varied. Different linkages for achieving this are shown, also with a drive for two wiper arms.

Title: Anti-gravity flying saucer-like machine - uses gyroscopic effect of simultaneous rotation of rotors about two perpendicular axes
IPC: B64C39/00
Filed: 1976-04-22
Abstract: The anti-gravity machine such as a flying saucer consists essentially of three elements, a vertical hub (1), one or more spindles (2) disposed diametrically and equipped with rotors (3) and a motor (4) coupled to the hub. Each rotor is connected, via a tube (6) freely mounted on the spindle, to a wheel (5) which runs on a track (7) furnished with a rubber surface thus ensuring that the rotors are turned when the hub rotates, the hub perhaps being powered by a linear electric motor. According to the patentee the force produced by the simultaneous rotation of the rotors in two mutually perpendicular directions is directed upwards against gravity and if the speeds of rotation are sufficient then the force will be enough to lift the machine and its container from the ground.
