Title: Improvements in automatic weighing machines
IPC: G01G11/02
Filed: 1926-04-24
Abstract: 270,079. Brown, S. C., and Denison & Son, Ltd. April 24, 1926. Apparatus fitted to conveyers. - In an automatic integrating conveyer weigher of the type that weighs both empty and loaded conveyer strands, mechanism is provided for (a) temporarily isolating the whole of the weighing system from the conveyer to permit of zero adjustment of the weighing mechanism, (b) ensuring that the integrated weight records can only be taken when the whole conveyer has passed over both weigh tables an integral number of times. As shown in Fig. 1, a bucket conveyer A passes over fixed tracks B1 - - B4 and over detached tracks C1, C2 supported as usual on weighing levers D1, D2, E. An integrator of usual form, driven from the conveyer transmits its results to an indicator F. Arranged alongside the tracks C1, C2 are additional tracks (not shown) adapted to be raised by hand-operated cams J1 - - J4 so as to engage the flanges of the conveyer wheels and thus lift the conveyer clear of the weighing tracks. The balance of the weighing system may then be tested separately from the conveyer. To prevent an indication or record of the weight being taken unless the conveyer has made a complete number of rotations a sliding masking plate M, Fig. 3, normally obscures the indicator F but is moved to display the indications by a cam plate O on the conveyer acting through connection P, Q, R. The masking plate, in its obscuring position, obstructs the free movement of the printing handle L and prevents a record being obtained. In the indicating position a notch M1 in the masking plate permits the printing handle freedom to produce a record. After the passage of the cam plate O a weighted lever S returns the masking plate. To permit readings to be taken at leisure the lever S and rod P may be held in the upper position by a hand-operated stop cam V, the indicator F being disconnected from the integrator gear wheel K by a clutch T. The masking plate M may be moved by electrical means instead of by the cam plate 0; instead of a masking plate, the indicator may normally be in darkness and may be rendered visible at the appropriate time by electrical illuminating means. In order to run the integrating mechanism during an equilibrium adjustment of the weighing mechanism without running the conveyer the integrating mechanism which drives the gear wheel K, Fig. 4, and the indicator F, is temporarily driven by an electromotor W. The drive from the conveyer to the integrating mechanism is disconnected and is transferred to the motor W by a hand-operated clutch V. In a modification where the motor W is dispensed with a gear X may be declutched from the conveyer and the integrating mechanism rotated by hand.

Inventor: GILKS JAMES HARRIS
IPC: C07C69/80
Filed: 1959-04-01
Abstract: A process for the production of diesters of isophthalic acid comprises reacting together isophthalic acid and at least one alcohol in the presence of a relatively large amount of a strong mineral acid and a compound which has the effect of decreasing the acidity of the mixture during the course of the reaction.  The esterification is preferably carried out using as catalyst about 1% by volume sulphuric acid based on the reactants and an alkali metal sulphate, halide, phosphate, borate or carboxylate or a metal oxide as the acidity decreasing compound.  These compounds may be introduced in solid or a liquid form before or during the esterification.  Examples describe the preparation of iso-octyl and iso-decyl isophthalate in the presence of sodium sulphate, sodium chloride, trisodium phosphate and disodium hydrogen phosphate.  The resulting esters are less coloured than those prepared in the absence of the acidity decreasing compounds.  The Provisional Specification refers to the esterification of aliphatic and aromatic dicarboxylic acids in general.

Title: Motion plcture camera with automatic exposure-regulating device
IPC: G03B7/085
Filed: 1959-04-19
Abstract: 855,049. Photo-electric exposure control. AGFA A. G. April 1, 1959 [April 19, 1958], No. 11118/59. Class 40(3). [Also in Group XX] Relates to motion picture cameras with photoelectric control of diaphragm opening. According to the invention a mechanism retarding the film feed is provided and is effective from the instant of camera release until the exposure regulator has functioned. The embodiments relate to spring-driven cameras in which the film is advanced by a claw. In both embodiments gear and worm wheels 5, 6 on shaft 3 rotate during running down of the camera spring mechanism (not described), shaft 7 carries a shutter 9 rotating in front of film 10, a claw 11 is periodically reciprocated by a known claw drive and comprises lugs 11a, 11b by which it can turn about shaft 12 and concurrently slide thereon for film advancement, and shaft 15 carries a disc 14 and a pinion 16 in engagement with gear wheel 5; pressure on claw end 11c towards the front 1a of the camera brings the claw out of engagement with the film by pivoting it about shaft 12 against spring 13. In the first embodiment a friction coupling 21 is provided between pinion 16 and disc 14 which has a recess 14a such that the claw tip can engage in film 10 when claw 11c enters the recess. Camera release lever 17 moves back and frees shutter 9 and thus gearing 8, 6 so that the spring mechanism can rotate shaft 3; the lever is restored by spring 17d. On release lever operation surface 17b pivots lever 18 about shaft 19 so that end 18c liberates projection 14b and thus disc 14 takes part in the running down of the spring mechanism via friction coupling 21. Claw end 11 c thus slides out of recess 14a whereby the claw tip comes out of film engagement, when the release lever is pressed home surface 17c lies opposite surface 18b and lever 18, under spring 20 loading, is rotated back so that its end 18c by means of projection 14b prevents disc 14 from further rotation after one revolution. Film 10 &c. now continue to be moved until lever 17 is relieved from pressure at which instant end 18c again releases disc 14 so that the claw tip comes out of film engagement before the camera mechanism stops. In the second embodiment disc 14 has an unrecessed circular periphery and is releasably connected with pinion 16 by a crown wheel coupling, Figs. 4 and 5 (not shown).

Heading F2F. A combination power valve and master cylinder unit for a motor vehicle comprises a manually operated plunger 4 (or 24) which acts through a spring 7 or hydraulic linkage to move right a bush 5 and valve control sleeve 6, movement of the latter acts through a rod 20 to open a valve 21 whereupon pressure fluid from an accumulator is supplied through a chamber 17 and duct 11 to the brakes on one axle of the vehicle and is also supplied to the rear face 18 of a piston 2 (or 32) of the master cylinder 1 which operates the brakes on the other axle. When pressure in the chamber 17, corresponding to braking pressure, exceeds pedal pressure on the plunger 4 (or 24), the bush 5 is moved left to allow fluid to pass from the chamber 17 through the interior 13 (or 29) of the sleeve 6 to a reservoir 10. Should the pressure fluid supply fail the brakes may be operated by direct mechanical thrust from the plunger 4 (or 24) on the master cylinder piston 2 (or 32). In Fig. 2 the plunger 24 is hollow and communicates through an element 27 with a chamber 28 and through a duct 40 in a piston 38 with a chamber 35 in the master cylinder piston 32 which assembly forms an hydraulic linkage. Initial rightward movement of the plunger 24 against a spring 44 moves the plunger into abutting engagement with the piston 38 and thus closes the hydraulic linkage. Further movement of the plunger 24 moves the piston 38 right against a return spring 36 and thus tends to compress the liquid in the linkage whereupon the liquid pressure in the chamber 28 moves right the bush 5 and valve sleeve 6 to engage the brakes.
