Title: Acoustic measurement of liquid or powder surface level - by alteration of phase to produce standing wave
IPC: G01F23/296
Filed: 1973-08-14
Abstract: The level of the surface of a fluid or powder is measured by inserting a tube with the upper end closed into the material. Sound waves are reflected from the surface and picked up by a receiver shielded from the direct sound wave. The echo path can be used to set the frequency of the source according to the path length, or to vary the phase of a wave from a fixed source. In each case frequency or phase to voltage converters can be used to give an output proportional to the level. Alternatively the cavity may be excited by white noise to find the frequency at which a standing wave is formed.

Title: DC motor protective switching cct. - has regulating signal dependent on supply current controlling monostable or bistable flip-flop
IPC: H02H7/08
Filed: 1974-11-04
Abstract: The protective switching circuit, for d.c. motors, uses a signal proportional to the motor supply current to operate a protective cut-out system. The signal magnitude depends upon a current inversely proportional to the motor's operating voltage. The signal is applied as a base-emitter voltage to a flip-flop input transistor. The flip-flop may be either monostable or bistable. The signal is obtained from a resistor. The supply voltage is adjusted by a potentiometer whose tapping is connected to the resistor. The collector of the flip-flop output transistor is coupled over a diode to a control line.

When unloading, these steps are reversed. When the legs are first lowered, the rearward feet (81, 82) come down to the ground, through openings (83, 84) left in the bottom of the unit, whilst the forward legs are first laterally extended to clear the sides of the unit.

Title: Selective electroplating of small parts - eliminates masking, and is suitable for the contact surfaces of reeds in relays
IPC: C25D5/02
Filed: 1975-02-07
Abstract: Improved process for obtaining electroplated coatings on localised surfaces, the novelty being the use of a moving solid element which is partly immersed in the electrolyte so the latter is drawn up to from a layer of liq. with a controlled thickness and position. The surface of the moving element may be smooth or contain slots, undulations, grooves or other surface irregularities having the object of picking up the electrolyte and controlling the thickness of the liq. layer; the element may also be made of a porous material so it is impregnated with the liq., thus improving conduction. The thickness of the layer is pref. varied by altering the depth of immersion of the element and/or its speed. Selective electroplating the surfaces of small parts e.g. depositing precious metal on the contact end of a reed for a sealed reed relay. Substantial savings in the hand labour previously involved in masking the zones which do not require plating.

Title: Continuously moving film strip cutting mechanism - has linkage moving blade support frame so counter blade moves with strip during cutting
IPC: B26D1/58
Filed: 1975-02-27
Abstract: A mechanism for cutting continuously moving film strip has a frame made up of two parallel bars, each end mounted on vertical levers pivoting in supports. The film strip passes between these bars, at the same level. A fixed cutter blade fits transversely between the bars, under the film. A moving blade is above the strip, pivoting on bars at one end and moved up and down by an accentric cam driving a linkage. This cuts the strip into predetermined lengths. The fame is reciprocated along the path of the strip, at the same speed, by a connecting rod and eccentric cam mechanism driven by a motor.

Title: Ceramic casting moulds mfr. - by calcining, cooling, applying preheated particulate material and compacting
Inventor: PEREVOZKIN J L
IPC: B22C9/00
Filed: 1975-03-07
Abstract: Ceramic moulds are prepared to receive molten metal by calcination followed by cooling to 30-60 degrees C, after which a particulate material heated to 600-850 degrees C is applied to the outer surface and compacted. The moulds are retained in the particulate material for 10-40 mins. The process is applied particularly to the handling of moulds formed of quartz which are prone to cracking during calcination. The cooling of the moulds immediately after calcination permits visual examination for defects and necessary rectification. The number of reject castings is thereby reducted.
