Title: Electrical circuit for producing electrical audio signals representative of clapping
IPC: B06B1/02
Filed: 1980-03-14
Abstract: A circuit for producing at an output terminal (1) a signal representative of a group of people clapping their hands in unison comprises a noise generator (2) producing broadband noise which is fed through a bandpass filter (3) to give the noise signal a defined note or pitch and via a gate (4) to one input of a mixer (5). A pulse generator (6) supplies a voltage controlled oscillator (7) which, for each input pulse, produces a frequency sweep determined by the voltage excursion of the pulse and sweeping upwardly and downwardly respectively with the rising and falling edges of the pulse. The output of oscillator (7) is gated such that only the frequency sweeps and not the fundamental frequency are fed to a second input of mixer (5). The mixer combines the background "crashing" signal derived from noise generator (2) with the "individual handclapping event" signals from oscillator (7) to produce the requisite output signal. <IMAGE>

Patent GB-2058383-A (GB)
Title: Sensitive Photothermographic Material
IPC: G03C8/40
Filed: 1980-09-08
Abstract: A silver image and a uniform distribution of an azophenol or azonaphthol image dye capable of being bleached in a silver dye-bleach process are produced by exposing and heating overall a sensitive photothermographic material containing a photosensitive silver salt, a silver halide developing agent, a base release agent and a precursor of the image dye containing a blocked auxochromic hydroxyl group. During heat processing, the base release agent both activates the developing agent and deblocks the blocked hydroxyl group to shift the spectral absorption of the dye. If the silver image and image dye are heated in the presence of a silver complexing agent, an acid and, if necessary, a silver dye-bleach catalyst and/or a thermal solvent, a dye image is formed as a result of the bleaching of the silver image and of amounts of the image dye proportional to the amounts of image silver bleached. The silver dye bleach chemicals can be provided in a layer of the photothermographic material or in a layer of an activator sheet heated in contact with that material. These materials may be used in diffusion transfer processes.

Title: Vehicle lamp
Inventor: MALLETT ANTHONY THOMAS
IPC: B60Q1/26
Filed: 1981-10-09
Abstract: A vehicle lamp assembly 11 for a combined head lamp 12 and turn- indicator lamp 13 comprises bulbs 17 and 18 for the head lamp and turn- indicator lamp respectively. An uncoloured transparent lens 21 covers both bulbs. An amber coloured filter 22 is located between the lens and the turn- indicator bulb 18 so that when the bulb 18 is lit it shows amber. The outside of the filter 22 is metallised to form a reflective surface which does not prevent light from the bulb emerging through the filter from outside the lamp so that the colour of the filter cannot be seen when the lamp bulb 18 is not lit. The interior of the lamp assembly thus appears a generally uniform colour when the lamp is unlit giving a pleasing visual appearance to the lamp assembly. <IMAGE>
