Title: Fold-flat document wallet - has flap attached to front panel by rivet sliding in slot during erection
IPC: B42F7/00
Filed: 1974-05-10
Abstract: The document wallet is made from a blank (1) with two rectangles (2, 3) to form the front and rear, and a triangular flap (7) which when the blank is folded, is attached to the front (3) to form a pocket, open on two sides. The open side opposite the flap, carries tabs (e.g. 2a, 3a) for marking to indicate the contents. The vertical (9, 10) and horizontal (5, 6) fold lines are spaced apart sufficiently to ensure that a substantial stack of documents can be held inside. When the flap is folded over the front, a diagonal slot (11) registers over a hole (3b) in the front, and a hollow rivet is attached so that the flap is attached to the front. To enable the wallet to fold flat after the riveting operation, the rivet slides along this diagonal slot.

Title: Corner plate guide for sliding window - attached at upper corners preventing wear to weatherproof seal
IPC: E06B3/46
Filed: 1974-06-13
Abstract: A corner plate for use on sliding doors and windows consists basically of a right angled corner plate with the two legs (35, 36) of unequal length. The shorter leg (36) has at least one projection (40) on a face external to the angle while the other has a slot (45) into which a screw (46) is inserted. The corner plate is attached to each of the upper corners of the sliding door or window so that the projection engages in a longitudinal inverted U-shaped fillet (31) on the frame and guides the door/window when moved. The use of these plates prevents undue wear and tear on the water and air tight strip surrounding the door or window.

Title: Optical-electronic position or displacement control system - uses paired photo receivers and their illumination difference to control two state electronic circuits
IPC: G01D5/34
Filed: 1975-02-07
Abstract: Opto-electronic position or displacement control system uses pairs of photoelectric (21, 22) receivers each pair being associated with a two state electronic circuit. The photoreceivers (21, 22) are illuminated through two diaphragms (4). Each pair of photoreceivers (21, 22) is mounted in series with a common electrode between two supply connections. The signal on the common electrode measures the illumination difference between a pair of photoreceivers and controls the state of the electronic circuit associated with the pair. One of the two diaphragms (4) is connected to a fixed body and masks both the photoreceivers of the pair. The system has a moving element (3), and the light beam passing through the diaphragm is perpendicular to the line of displacement of the moving element (3) so that the detection of a difference in the light intensity on a pair of photoreceivers corresponds to a predetermined displacement of the moving element (3).

Title: IC engine flexible support - has plastic insert in one of two diametrically opposite recesses around elastomer block in housing
IPC: F16F1/387
Filed: 1975-03-24
Abstract: The engine (M) is supported on the chassis frame (B) by the support which has a block of elastomer (3) moulded in the housing (2).

Title: Radiation detected by latent metastable state of particles - changed into normal state by incident radiation
Inventor: DRUKIER ANDRZEJ KAMIL
IPC: G01T1/16
Filed: 1975-11-28
Abstract: A method of detecting electromagnetic or particle radiation utilises the phenomenon of the transition of a homogeneous grain of a superconducting substance of the first type out of the metastable superconducting state into the normal state; this transition is produced by the effect of a photoelectron expelled by the impact of the photon or particle on the grain. The superconductivity and the Meissner effect remain in a latent state in the particle after the critical value of the surrounding magnetic field has been exceeded, producing a 'superheated' condition of the metastable state. A spherical homogeneous grain of the material suddenly loses this superconductivity when subjected to beta radiation. This loss of superconductivity is detected by measuring an electrical or magnetic variable associated with the change of state. A probe or detector is described which contains superheated metastable particles surrounded by a dielectric. Pref. dielectric material is epoxy resin.

Title: Mfr. of large section castings with internal tubing - involves casting the metal around the tubing while the tubing is injected with atomised water droplets
IPC: B22D19/00
Filed: 1977-02-08
Abstract: A large section metallic article having hollow tubular internal portion of any desired profile and of thin section is fabricated from the same metal as the tubes. The article is formed by casting the metal around the tubes or tubing at the same time as a two-phase dispersion of liquid/gas in the form of a turbulent suspension of very fine liquid droplets is injected into the tubes or tubing. The liquid is of a type resistant to coalescence and is atomised inside the tubing by a gas stream directed into the tubing to strike the liquid which is tangentially through a transverse section at the end of the tubing. Process avoids the risk of the tubing becoming fisured or pierced during casting and thus of the metal penetrating the tubing and closing or blocking it. The process avoids the risk of the tubing being heavily deformed.
