Title: Method of measuring power consumption of A.C. - uses comparison, inversion and counting of current proportional signals
IPC: G01R21/133
Filed: 1974-03-04
Abstract: A voltage proportional to a sinusoidal supply voltage and a current proportional to the corresponding supply voltage are sampled. During the same sign half periods of the voltage the current values are integrated to obtain a time varying signal (UA) from a first zero value, with a constant slope, of constant sign. Signal (UA) is compared with a step value (E) which is a function of the amplitude of the supply voltage. The slope of (UA) is inverted when it reaches a value equal to the step value (E). The integration is continued till (UA) again reaches the first zero value. The slope of (UA) is again inverted to obtain an output signal of frequency (f) proportional to the power being measured, a count of the number of periods of the output signal allowing the determination of the energy consumed during this time.

Title: Small batches of food frozen with dry ice - sprayed on as ten or more successive layers
IPC: A23L3/375
Filed: 1974-05-15
Abstract: A freezing process and a thermally-insulated freezing cabinet suited to the process are claimed, in which a batch of products is frozen by applying to and maintaining on the surface of each product item a thin coating of dry ice applied as a succession of sprayed-on layer; pref. at least ten layers of dry ice are applied over a period of between 10 and 60 min. Suitable delays are allowed between successive applications to permit a degree of temp. homogenisation, which may be accelerated by fanned circulation of the atmos. within the cabinet.

Title: Driver protection frame for tractor - consists of hollow members filled with granular material for protection on overturning vehicle
IPC: B60R21/13
Filed: 1974-08-12
Abstract: The protection frame is used for traction vehicles and those used on building sites, agriculture and forestry. It ensures that the driver and the co-driver are able to survive an accident in which the vehicle is overturned. The advantages of the tubular constructions are combined with those of the solid profile. The buckling of tubular section is prevented and hence these members are able to exert resisting moments to loads met in such an accident. The tubular frame made from hollow enclosed profiles is filled with a granular material such as sand which does not have any hydraulic characteristics. The grains can be also bonded to form flexible or rigid filling. A corrosion protection and sealing agent can be mixed into the filling material. The filler can be placed within the frame during frame manufacture or subsequently by vibrating or by heating.

Title: Indicator for gas remaining in gas bottle - pref. has display window and scale in sprung loaded bottle support
IPC: G01G23/32
Filed: 1974-08-12
Abstract: Difficulty in determining how much gas is remaining in a liquid gas bottle is overcome by resting the bottle on a sprung loaded support with a visible display. A gas bottle support comprises a cylindrical element (1) which rests on the ground. A second cylinder element (2) slides over the first element and is dished (4) to receive the base of the gas bottle. Springs within the two elements support the weight of a gas cylinder. A coloured area (3) on the side of the lower element (1) is visible through a graduated window in the side of the upper element (2). The display depends on the weight of gas in the gas cylinder.

Title: Contact free signal transmission between rotating systems - using light modulated signals and optical fibres arranged in ring formations to transmit continuous (NL240576)
Inventor: MORAND JEAN FRANCOIS
IPC: H04B10/00
Filed: 1974-11-20
Abstract: The device is for transmitting large quantities of information in the form of continuous signals between two mutually rotating bodies, without mechanical contacts. This function has hitherto been performed by devices such as slip rings, and the mechanism described here constitutes an advance on those. The information to be transmitted must be used to modulate a light source, the output of which is passed down a bundle of optical fibres (41, 42, 4n). Each bundle is spread out at one end to form one ring of a multiple ring disc of fibres (91, 92,.....9n) which face in a flat plane, a matching set of concentric rings (141, 142,.....14n) feeding in turn another set of bundles of optical fibres mounted on the second rotating body. These in turn supply photocells (191, 192, .....19n).

Title: Cross country ski binding - press down linkage has over centre cam action against spring to hold boot front welt
IPC: A63C9/20
Filed: 1974-11-18
Abstract: A plate on the upper surface of the ski locates the ski boot. In front of this is a bracket (9) carrying a pivoting arm with pegs (6) to locate in holes in the ski boot welt. A lever (11) pivots (12) on this arm and is connected to the fixed bracket by a kidney shaped articulated link. The system is spring loaded (10) and, when the lever is pressed down, the arm descends to contact the welt. At this point, the pivot centre (13, 14) of the articulated link and the lever (12) are in line. Further downwards movement exerts pressure on the arm and locks the linkage.
