Title: Mass Spectrum Analyser
IPC: H01J49/42
Filed: 1966-09-12
Abstract: 1,161,092. Mass spectrometers. ELECTRONIC ASSOCIATES Inc. 12 Sept., 1966 [13 Sept., 1965], No. 40578/66. Heading H1D. In a mass spectrometer of the quadrupole type such as described in Specification 773,689 in which either the R.F. voltage or the frequency is varied to sweep the mass spectrum, the ratio of R.F. voltage to D.C. voltage is varied as a function of R.F. voltage or frequency to provide a uniform spectral dispersion for differing masses, i.e. mass peaks of uniform breadth are obtained and hence a constancy in resolution. The electrodes may be circular or hyperbolic in cross-section. In varying the R.F. voltage the D.C. voltage may be maintained proportional to the sum of the R.F. voltage and a constant voltage (Fig. 8), or the magnitude of the D.C. voltage may be varied as a predetermined function of the R.F. voltage (Fig. 9). The substance to be analysed is passed through the ionizer as a continuous vapour stream.

Title: Pulse signal generator circuit arrangements
IPC: H03K5/04
Filed: 1974-09-19
Abstract: 1477713 Pulse generator SONY CORP 19 Sept 1974 [4 Oct 1973] 40909/74 Heading H3T A pulse signal generator arrangement comprises first and second pulse generators producing first and second pulse rectangular trains and respectively D.C. coupled to the set and reset terminals of a bi-stable 13 and a logic circuit with three input terminals D.C. coupled respectively to the two pulse generators and the output of the bistable. In use the bi-stable 13 is set by the leading (rising) edge of the first pulse S c  and reset by the leading edge of the second S D , a first logic circuit, which may be a NOR 14, is supplied with an output S F  from the bi-stable 13 and with the second pulse signal S D  to produce a third pulse signal S G  which is held in one state from the trailing edge of the second pulse signal S D  to the leading edge of the next first pulse signal S c , and a second logic circuit, which may also be a NOR 15, is supplied by the first and third pulse signals (S c  and S G ) to produce a fourth pulse signal S H  which changes state at the trailing edges of the first and second pulse signals, S c  and S D . The pulse generators may be the combination of a magnet on a rotating body (1, Fig. 1B, not shown) and two pick-up coils (5, 6). The bi-stable may be an RS type flip-flop. The NOR circuits may be made of two transistors each 23, 24 and 26, 27, Fig. 5. Alternatively the first logic circuit may be an Exclusive OR, needing a reversal in phase of the input from the bistable, and the second logic circuit may be an OR to produce a pulse signal reversed in phase from that in the embodiment shown. The pulse generators may each include a mono-stable multivibrator 9, 10, Fig. 3, to produce the predetermined pulse width outputs. Varying the pulse width from the monostables effectively, shifts the position of the magnet relative to the associated coil, thereby allowing mechanical tolerances to be taken up electrically. The rotating device carries two magnetic recording heads (2, 3 Fig. 1B) to record signals on a video tape that is wrapped 180 degrees around the rotating device (Fig. 1A, not shown). The circuit can be integrated, being suitable since the capacitors used in prior art for differentiating the waveforms S c , S D  have been eliminated.

In making a sandal with a shaped insole 3 in which the upper 1 extends over the edge of the insole but not around the entire edge thereof, and the outsole 5 is moulded thereto by vulcanizing or injection moulding, the insole is sufficiently elastic for the parts of the upper to be pressed into the insole by the sealing edge 6 of the mould which thereby forms a continuous seal around the sandal. The insole is formed by the injection moulding of a mixture of cork waste and polyvinyl chloride paste. The ends of the upper are tacked to the underside of the insole. Specification 964,688 is referred to.

When an electric current flows through member 23, portion 19, resistor 31, portion 21, and lead 59 to casing 11, resistor 31 heats up heating up portions 19, 21, heating up bimetals 27, 29, but the heat from portion 19 is conducted away by member 23 whereas the heat from portion 21 is not, so that bimetal 29 bends more than bimetal 27 till they engage completing a low resistance circuit through the bimetals to energize a lamp. However when the pressure on tip 15 urges portion 25 against portion 21, the heat is conducted away from tip 21 so that portion 21 cools down and the bimetals open. Alternatively the bimetals may actuate a relay to operate the indicator or a latching relay or circuit to provide a steady signal. Suitable materials for the various parts of the sensor including the bimetals are given.

Title: Process for producing a concentrated coffee extract
Inventor: FRANCK GEORGE
IPC: A23F5/48
Filed: 1959-12-14
Abstract: Coffee meal is formed into pellets which are distributed through ground roasted coffee which is then extracted with water. Coffee meal is the residue after oil has been expressed from roasted coffee.  The pellets are substantially larger than the particles of ground coffee and are distributed through a column thereof.  Fines sifted from ground roasted coffee may be mixed with the coffee meal and this blend pelletized or the fines and meal may be pelletized separately and mixed with the ground roasted coffee.  Pelletizing is achieved by shaping under pressure and a bonding agent, e.g. moist coffee extract may be used. Otherwise, non-coffee bonding agents may be used, viz. polyhydroxy compounds such as higher polyhydric alcohols, e.g. sorbitol and mannitol; monosaccharides, e.g. frictose, sorbose, glucose or galactose; disaccharides, e.g. lactose and maltose and other polysaccharides.  The coffee oil is added to the extract either before or after drying.  A layer consisting only of roast coffee may be used adjacent the draw-off point.
