Title: Stereoisomeric cyclohexene aldehydes and their use in perfumery
IPC: C07C45/69
Filed: 1980-05-06
Abstract: Stereoisomeric aldehydes having the formula:-   <IMAGE> have been found to possess attractive odoriferous qualities. They are useful ingredients of compounded perfumery compositions. They can be produced by the thermal isomerisation of the mixture of four stereoisomeric aldehydes produced by the Diels-Alder addition of acrolein to allo-ocimene. The distinctive odoriferous qualities are exhibited by all those mixtures of aldehydes in which these two steroisomers predominate.

Title: Four-pole network for separating signal of two double-polarised frequency bands
IPC: H04B7/14
Filed: 1980-08-07
Abstract: A multi-port network, for separating signals of two double-polarised frequency bands in a directional-radio or satellite-radio antenna feed, comprises a first polarisation converter (11) for converting linear into circular polarisation and vice versa, the first converter (11) being designed for minimum intrinsic ellipticity in the lower frequency band and being connected in front of a first symmetrical polarisation separating filter (10) for coupling of the lower frequency band into waveguides 14, 15. Connected between the first filter (10) and a second such filter (12) for the upper frequency band is a second polarisation converter (13) which compensates for the residual ellipticity in the upper frequency band. The second polarisation converter (13) comprises first wave-coupling means for reducing the frequency-dependence of the residual ellipticity while simultaneously increasing the value of the residual ellipticity, and second wave-coupling means for reducing the value of the residual ellipticity and its frequency-dependence to a minimum (Figures 6,7, not shown). <IMAGE>

Patent GB-2070363-A (GB)
Title: Apparatus for converting the period of a periodic signal to a digital count signal
IPC: G01L9/00
Filed: 1981-02-17
Abstract: The output of a vibrating diaphragm pressure sensor 20, which output is a periodic signal with a periodicity a function of measured pressure, is applied to the input of a sensor period counter 22 through a period clock gate 23. The period clock gate 23 is enabled by the first occurring leading edge of the vibrating diaphragm sensor output signal after the occurrence of a start conversion command. The enable signal for the period clock gate 23 also enables a high speed clock gate 28 through which a high frequency clock signal is gated into a high speed counter 27. When the most significant bit of the high speed counter 27 switches to the ONE state, both gates 23,28 are disabled upon the occurrence of the next following leading edge of the sensor output signal. The sensor period is derived from the output of the sensor period counter 22 and the output of the high speed counter 27 by a processor 29 that divides the number of sensor periods that have occurred into the time that the gates were enabled. The processor 29 also controls the conversion time by preloading the high speed counter 27 with a conversion time control number. <IMAGE>

Patent GB-2100903-A (GB)
Title: Character recognition systems and methods
Inventor: BURLEY MICHAEL
IPC: G06V10/10
Filed: 1981-07-03
Abstract: A character recognition system has a linear array of photocells 10 which is moved across the character represented on a medium 8 to produce an array of pixels arranged in columns and rows. These are noise- reduced, 18, by relating the grey-level of each pixel to a continuously updated reference level representing the current "whitest white" level. A preprocessor 52 then converts each pixel into a "black" pixel or a "white" pixel. This is done by summing each pixel's grey level with those of its four immediate neighbours along four axes (vertical, horizontal and two diagonals). If the sum in any axis exceeds a threshold, the pixel is deemed "black"; otherwise it is "white". A velocity compensation unit 120 then compensates for varying velocity of the wand 10 by ensuring that each character is represented by only 16 columns of pixels (arranged side by side across its width). The result is a 16x16 matrix of pixels. Character recognition is carried out, 240, by multiplying each such matrix by its transpose to spread the character details across the matrix and then comparing the resultant matrix with a set of reference matrices. <IMAGE>

Title: Leaf spring railway bogies
IPC: B61F5/06
Filed: 1981-11-26
Abstract: An H-frame bogie comprises a leaf spring assembly 15 connected between wheel axles of the bogie. The leaf springs 15 have a non-linear spring characteristic resulting from identical cross-section and length of each leaf 17. The arrangement causes the wheel axes to radiate as the bogie negotiates a curve, thereby contributing to reduced wear and reduced possibility of derailment. The leaf spring 15 acts as a load equalizing beam. The connection between the bogie and the vehicle body is by a centre bearing assembly 6 which transfers horizontal forces and side bearing assemblies, each including a gear rack engaging with vehicle body rollers 10, which transfer vertical forces. <IMAGE>

Title: Delay detonator
IPC: F42B3/16
Filed: 1982-04-26
Abstract: improved uniformity of timing, and particularly reduced sensitivity of timing to minor variations in delay charge size, are achieved in delay detonators by placing a loose load of a flame-sensitive ignition composition between a pressed delay charge and an ignition assembly, e.g., a percussion primer, at the actuation end of the detonator. The loose ignition charge has a free surface and is adapted to be ignited in response to direct contact with flame emitted from the ignition of a charge in the ignition assembly. Preferably, the delay charge is pressed into a plastic carrier which, in a non-electric detonator, has an open end terminating between the walls of the detonator shell and a primer shell that closes the actuation end of the detonator, and the ignition charge is loosely loaded into a metal capsule seated against the delay charge.

Title: System for verifying design of electronic component
Inventor: SMITH EDWARD
IPC: G06F17/50
Filed: 1984-03-26
Abstract: A method for verifying the design of a digital electronic component in which the component is replaced by a simulation unit 20-27 connected to the intended host system. The simulation unit has a memory 23 for holding responses to stimuli from the host system. If the required response is not in the memory, it is calculated and placed in the memory, and the operation of the host system is then re-started from the beginning. In this way, the required set of responses is built up incrementally in the memory until, eventually, the operation of the host system can run to completion. Another RAM 26 of the simulation unit has the same number of locations as the first RAM 23 and is also addressed by the counter 22. For each calculated response loaded into the first RAM the corresponding stimulus which initiated that response is loaded into the second RAM. Consequently, whenever a response is read out of the first RAM the corresponding stimulus is read from the second RAM and compared 27 with the actual stimulus input on path 20. If they do not compare true the simulation is halted. <IMAGE>
