Title: Coin wrapper
IPC: B65D65/18
Filed: 1981-02-09
Abstract: A coin wrapper comprises a jacket 1, formed as a truncated cone with a stiff bottom disc 2 at its narrow end, the jacket being of thin flexible paper 3 over only a portion of the circumference of the jacket 1 with the remaining portion being formed by a transparent strip 6, which joins the two longitudinal paper edges 4, 5 so as to form a window. The bottom disc 2 is made of or coated with heat- sealable material and has holes to prevent stacked wrappers from sticking together due to underpressure between the bottoms. As a tear aid, a grip tab 7 can be punched in the upper end of the transparent strip 6. Said strip can also be perforated for facilitating opening. Alternatively, a tear strip or string can be incorporated e.g. between an edge of the transparent strip and one of the paper edges 4 and 5. <IMAGE>

Title: Acoustic imaging devices
IPC: H01J31/495
Filed: 1981-05-02
Abstract: By using lenses, mirrors and gratings made of the appropriate materials sound radiation can be refracted, reflected and diffracted in much the same way as can light. It is usual to convert a formed sound image into a visible image. One technique which has employed for this is basically a television camera tube (usually of the vidicon tube type) but with an internally-mounted piezoelectric array in place of the conventional light-sensitive target, which array is acoustically coupled to the tube's front face. In sound tubes such as this a number of significant problems resulted in their failure to achieve wide use. The invention seeks to overcome these problems by making the front face of the tube "through- conductive", and by then mounting the piezoelectric array upon the face's outside surface. This invention provides an acoustic image conversion device comprising   a) a scanning electron beam tube (10, preferably of the vidicon type) the scanned front face (11) of which is through-conductive, and b) a piezoelectric array (front electrode 12, piezoelectric element 13 and rear electrode 14) mounted upon the outside surface of the tube's scanned face 11, whereby in operation an acoustic image formed upon the piezoelectric array (12, 13, 14) causes charge separation thereacross which is coupled via the through-conductive face (11) into the tube and there "read" by the scanning electron beam, thus providing an electrical signal corresponding to the acoustic image. <IMAGE>

Patent GB-2084416-A (GB)
Title: Position detecting apparatus
IPC: H03M1/00
Filed: 1981-09-11
Abstract: An optical shaft encoder consists of a multiple element LED light source with very narrow width emitting windows which are focussed on to one side of a very finely encoded disc driven by the shaft. Only one of the source elements is on at a time, each element being labelled by its position in time. A single large area detector located on the other side of the disc collects the transmitted light. The detector therefore receives a sequence of light pulses, the sequence representing the position of the disc relative to the LED light source and hence the position of the shaft. <IMAGE>

Title: Improvements Relating to Gear Boxes
IPC: F16H3/091
Filed: 1981-09-11
Abstract: A three-speed gear box has parallel main (1) and lay (2) shafts. The middle and upper gear ratios are governed by the position of a spring- loaded actuator (13), pivoted about an axis (14) between and perpendicular to the shafts, which co-operates with sliding dogs (11, 12) splined to respective shafts. A trip can be engaged to hold the actuator in the middle gear ratio position, and when released the spring bias, aided by the dog teeth shape, throws one dog out of engagement and the other in, to engage top gear. Changing down can be effected by operating the actuator against the spring. A further sliding dog (9) selectively brings either of two gear pairs (4, 6; 5, 7) into use. A trip holds this dog in the low gear ratio position and when released the spring bias, aided by the dog teeth shape, throws it out of engagement with a gear (5) of one pair and into engagement with a gear (4) of the other pair. <IMAGE>

Title: Process and synthetic combustion chamber of variable turbulence
IPC: F02B1/04
Filed: 1981-04-21
Abstract: The synthetic combustion method, intended to achieve a reduced fuel consumption and an enhanced flexibility of compression ignition motors both with regards to the revolutions and load range and the sizing range, provides for the complete volume organization of the fluid circulation within the combustion chamber, by the temporary separation of the space of the vortex chamber, of the compartments of the combustion chamber located above the piston, only during the end of the compression period, during the rest of the cycle, the combustion chamber representing a unit, the whole combustion process being a synthesis between the methods of unitary chamber combustion and partitioned chamber combustion, the increase of turbulence being obtained as a result of the vector summing the three vortices at least, tridimensional circulation vortices, and the enhancement of the threshold (squish) effect generated by the piston which increases the decanting effect of the fluid. The combustion chamber has two housings which are separated by a spatial profile which enters the separation channel, profile defined by three direction surfaces at least which generate tridimensional circulation vortices and acts as a braking moving threshold for the vortex housing, by concentrating the rich mixture which burns within the decanting channel area, the fluid circulation within the vortex housing being thus determined, to meet the fuel jet at equicurrent and to displace a portion of the fuel on the incandescent head of a spark-plug.

Title: Synthesis of urea
Inventor: KAGECHIKA KATSUMI
IPC: C07C239/00
Filed: 1982-11-15
Abstract: In a cyclic urea process, CO2 and excess NH3 are reacted in a urea synthesis autoclave (201) and the crude urea melt is fed to a stripper (202) for separating unreacted CO2 and NH3 therefrom. In a later step, the CO2 and NH3 are absorbed in a liquid absorption stage (203) and the resulting absorbate is fed back to the autoclave (201) while fresh CO2 and NH3 are fed into the autoclave. At a desired operation stage in the synthesis process, part of a reaction stream such as the crude melt leaving the autoclave (201), is regularly sampled and is passed to a quantitative analyser (205) for determining its ammonia and ammonium carbamate contents. The analytical data is correlated with an alteration of the operation that is to be effected so as to maintain the operation in a desired state. By this means, the analytic data can be used to control the overall synthesis process to a desired operating state. <IMAGE>

Title: Starter switch
Inventor: MORTENSEN HAROLD R
IPC: F02N15/06
Filed: 1983-04-22
Abstract: A power switch for a shift starter drive system of an internal combustion engine includes a pair of electrical contact sets (60, 62) which are sequentially actuated by energisation of a coil (24) which attracts an armature (22) thus engaging the starter drive's pinion gear (12) with the engine's ring gear (18). The first contact set (62) actuated after a predetermined displacement of the armature supplies electrical power to the cranking motor (10) through a resistance (81) connected in parallel with the coil (24) and in series with the cranking motor (10). This increases the electrical power applied to the cranking motor. The end of the armature travel closes the second contact set (60) to apply full power to the cranking motor permitting normal cranking of the engine with the pinion gear fully engaged with the ring gear. In this position the coil (24) is short-circuited but a hold-in coil (26) remains energized as long as a starter push button switch (80) is closed. <IMAGE>

Title: Solid state image sensors
Inventor: SMITH JAMES MUIR
IPC: H04N5/372
Filed: 1983-07-13
Abstract: To overcome the effect of interference by high intensity radiation directed deliberately or accidentally into the imaging aperture, an image sensing apparatus comprises a solid state image sensor, a charge-coupled area imaging array for example, along with a control arrangement for causing the sensor to accumulate an image representative signal pattern and for controlling read-out of that pattern, and further an excess radiation sensing means, for example a separate laser-radiation detector, operable when an excess radiation level is sensed to cause the control arrangement to operate in a way which at least reduces the effect of the excess, for example by causing the signal pattern accumulated by the sensor during a first portion of the normal accumulation period to be dumped and reading out only the pattern accumulated over the remainder of the period. Senses having an overload drain may obviate the need for a separate interference detector.
