Title: Concrete form plate - has membrane held by supports on cross bolt which has recess for coupling piece where cross bolt section meets it
IPC: E04G17/00
Filed: 1974-12-23
Abstract: Form plate which dispenses with adjustments to corner formwork has the form membrane held by longitudinal supports which themselves are supported on cross bolts. These are suitable to take a coupling piece with a cross bolt section positioned to take the coupling piece. The cross bolt section is undetachable secured to the side of the cross bolt which faces the form membrane and the length of the cross bolt section is at most equal to the height of the longitudinal support. The cross bolt has a recess at the point where it meets the cross bolt section which provides space for a coupling piece.

Title: Absorbent nappy pad with one impermeable face - having impermeable border around other face to prevent the pad adhering to the skin
IPC: A61F13/15
Filed: 1975-02-10
Abstract: An absorbent nappy pad has one face rendered impermeable and the face which is in contact with the baby has an absorbant central zone with a flexible impermeable border. Once waste has been excreted by the baby it passes into the pad through the absorbant central zone and cannot leak, thereby preventing the nappy from sticking to the baby.

Title: Magnetic lithium-manganese-bismuth-iron oxides material - contg lithium fluoride and zirconium dioxide, for simple reproducible mfr
IPC: H01F1/34
Filed: 1975-06-04
Abstract: A magnetic material contg. Li, Mn, Bi and Fe oxides also contains ZrO2 and LiF, the proportions of the individual components being: 3-4 (wt.)% Li2O, 2-6% Mn2O3, 2-5% Bi2O3, 0.2-0.6% LiF, 1-5% ZrO2, the rest Fe2O3.

Title: Electric discharge lamp power supply unit - has low frequency current supply with high frequency voltage superimposed
Inventor: KANEDA ISAO
IPC: H05B41/04
Filed: 1976-01-08
Abstract: An electric discharge lamp power supply unit is used to provide a low frequency and a high frequency component to the lamp. The low frequency component is provided by a current source and the high frequency component comes from an overvoltage circuit. The power supply unit has a circuit connected to a discharge lamp (FL). A current source (E) at 50 or 60 Hertz supplies current to the lamp (FL). A transformer (L10) and a ballast coil (W10) limits this current. An overvoltage circuit with a capacitor (C2) and an ascillating circuit (R2) provides a high frequency voltage. This high frequency voltage is superimposed onto the low frequency current by the secondary winding (W20) of the ballast transformer (CH).

Title: HV pulse circuit for X:ray machine - sequentially discharges capacitors into transformer primary to produce HV on secondary winding
IPC: H05G1/22
Filed: 1976-03-31
Abstract: The high voltage pulse circuit is designed on the principle of discharge of capacitors. It uses a number of capacilon and includes means of charging them. The circuit has a step up transformer (TR2) having a primary winding (TR2P) a core (TR2C) and a secondary winding (TR2S). The circuit has selective switching means (COM) for discharging at least some of the capacitors (C1-C40). The capacitor (C1-C40) being sequentially discharged through the primary winding of the transformer. This induces a magnetic field in the transformer core which produces a high voltage in the secondary winding (TR2S). The voltage is rectified by means of diodes (D3, D4) and filtered by capacitors (CS1, CS2).

Title: PROM component marking system - with code printed on housing to represent specific shape and quality of unit
Inventor: BARRETEAU JACQUES
IPC: B41F17/24
Filed: 1976-07-02

Title: Rotor-locking prevention circuit for motor-driven machine - momentarily reverses rotor direction and disconnects supply from motor
Inventor: GOUIN MAURICE
IPC: B02C18/24

Title: Heating control for intermittently occupied building - uses pre-tested parameters to set controls for maximum efficiency and fuel saving
IPC: F24D19/10
Filed: 1976-11-02
Abstract: The system controls the heat input for a building which is only intermittently occupied, to achieve maximum efficiency and fuel saving. Tests are initially carried out inside the building to determine the time to raise the internal temperature a given amount, under the most unfavourable conditions of external temperature and loading. The reference slope provides a time temperature graph, passing through an abscissa given by the time of re-occupation, the ordinate being equal to the internal temperature required at that time. Similar measurements are taken for the time of leaving the building, these being used to set the control instrumentation.
