Title: Improvements in or relating to equipment for the measurement of linear thermal expansion
Inventor: SUGARMAN BERNARD
IPC: G01N25/16
Filed: 1960-09-07
Abstract: 915,248. Measurement of linear expansion. BRITISH GLASS INDUSTRY RESEARCH ASSOCIATION. Sept. 7, 1961 [Sept. 7, 1960], No. 30848/60. Class 40 (1). [Also in Group XL (b)] In an apparatus for the determination of the linear expansion of a solid sample, change in length of the sample moves a mirror, with resultant deflection of a beam of light; the extent of this movement is recorded. A temperature-sensitive device produces an E.M.F. which is applied in opposition to a voltage tapped from a resistor across a reference voltage source. A galvanometer measures the difference between the two potentials and controls a uniselector for changing the tap on the resistor at each temperature increment of T‹. The recording is produced by a pen or photographic recorder. In the general arrangement, Fig. 3, the sample 9 is heated slowly in a furnace 1. Extension of the sample rotates mirror 20 and causes a beam of light from lamp 23 to be deflected. In the pen recorder illustrated a photo-cell 24 autofollows the movement of the beam and an associated pen produces a trace 29 on the moving paper. A thermocouple 11 is adjacent the sample and feeds a unit which produces a pulse at each T‹ temperature increment. These pulses cause a second pen to give a scale trace 27. The record 29 is calibrated by means of a micrometer which rotates the mirror 20. In the case of photographic recording the pulses derived from the thermocouple output open the shutter of a camera which thereby records both the position of the light beam and the temperature, the latter being indicated by a lamp. The circuitry which determines the increments of T‹ comprises the thermocouple 11, Fig. 8, a source of reference voltage 39 and a tapped resistor 37 placed across the reference voltage source. In operation switch 49 is closed so that the movement 7X of galvanometer 7 is in circuit. The galvanometer registers the difference between the thermocouple output and the tapped portion of the reference voltage. When the galvanometer indicates a certain difference it actuates a switch 47, this causing uniselector 38, 41, 42 to be stepped one place. This changes the tapping-point on resistor 37, and the tappings are so chosen that a step occurs after each T‹ change. Lamps 40 indicate the temperature range over which the apparatus is presently operating. Bank 42 produces the pulses which operate the recorder pen 13, Fig. 3, or the camera shutter.

Title: Circuit for representing the frequency of a train of pulses as a binary number
IPC: H03M7/04
Filed: 1974-07-12
Abstract: 1480822 Analogue - to - digital conversion ROBERT BOSCH GmbH 12 July 1974 [14 July 1973] 30885/74 Heading H3H The frequency f1 of an input pulse train at terminal 10 is binary encoded by stepping a counter 40 downwards, following a segmented approximation to a selected one of a number of hyperbolic characteristics (H1, H2, Fig. 1, not shown) over a selected number of periods of the input pulse train, so that the final-count, transferred to a register 30, represents f1. The hyperbolic characteristic is provided by a decoder 46 and frequency multiplier 50 through which clock pulses are applied to the counter 40. When a first input pulse arrives at 10, a maximum value Z max  is loaded from a store 60 into counter 40 which is then decremented by the clock pulses. When the next input pulse arrives at 10, if the count in counter 40 is less than Z max /2, the counter is reset to Z max . If the count in 40 is # (Z max /2), the most significant bit in register 30 controls the illustrated logic-15 and 12 are AND gates-to suppress the resetting of counter 40 until the next following input pulse is received. The most significant bit also controls the decoder 46 and may control the maximum value store 60.

Patent GB-896262-A (GB)
Title: Hydrohalogenation of myrcene in presence of cuprous compounds
IPC: C07C17/08
Filed: 1959-09-10
Abstract: Myrcene monohydrohalides (i.e. myrcenyl, linalyl, geranyl and/or neryl chlorides, bromides and iodides) are prepared by treating myrcene with HCl, HBr or HI in the presence of cuprous chloride, bromide or iodide.  In the case of the hydrochlorination, the cuprous chloride may be produced in situ from copper or any cuprous compound. Hydrochlorination may be carried out at a temperature of from -25 DEG C. to 100 DEG C.  The presence of cuprous chloride decreases the production of myrcenyl chloride and alphaterpinyl chloride and favours the isomerisation of linlayl chloride to geranyl and/or neryl chloride; to produce a maximum yield of linalyl chloride the hydrochlorination should be carried out at lower temperatures with a minimum of catalyst for the shortest time; to produce a maximum of geranyl chloride, it should be carried out with larger quantities of catalyst, e.g. at least 0.1% of cuprous chloride at higher temperatures, e.g. of at least 15 DEG C.  The bromides behave similarly.  The hydrochlorination products contain some alpha-terpinyl chloride and myrcene dihydrochlorides.  The myrcene may be obtained by pyrolysis of beta-pinene.  The hydrochlorination products may be converted to the corresponding alcohols and esters.
