Title: Improvements in syringe hydrometers
IPC: G01N9/14
Filed: 1920-07-03
Abstract: 146,443. Edelmann, E. Feb. 26, 1916, [Convention date]. Hydrometers.-An hydrometer is housed in a transparent-sided syringe which sucks up enough of the liquid to be tested to float the hydrometer and to enable a reading to be taken. In the construction of Fig. 2, the hydrometer H rests in a tube E made of some non-breakable but partially flexible substance. An upper transparent tube A (glass) screws into the tube E, while a collapsible bulb C fits on the top of the tube A. This arrangement avoids risk of breakage of hydrometers and is particularly useful for testing electric batteries.

Title: Process for preparing substituted acetic acids
Inventor: CROOY PIERRE
IPC: C07C51/093
Filed: 1965-05-03
Abstract: Acetic acid derivatives of the formula <FORM:1032879/C2/1> in which R denotes a straight- or branched-chain alkyl group of 1-4 carbon atoms, M denotes hydrogen or an alkali metal, and X1 and X2 denote hydrogen or chlorine, except that X1 does not denote hydrogen if X2 denotes chlorine, are prepared by a process comprising (1) reacting benzene or an appropriate chlorobenzene with a trihalogen acetaldehyde under anhydrous conditions in the presence of a Friedel-Crafts catalyst, (2) hydrolysing the produet to yield the corresponding carbinol, (3) treating the carbinol with a solution of an appropriate alkanol in an alkali-metal hydroxide or alkoxide and (4) optionally converting the alkali salt so obtained into the free acid.  Thus, in Example 1, benzene is reacted with chloral in the presence of aluminium chloride and the product is hydrolysed to yield phenyltrichloromethyl carbinol; the latter is treated with a methanolic sodium hydroxide solution to yield the sodium salt of a -methoxyphenylacetic acid, which may then be acidified to yield the free acid.  Other examples describe the similar manufacture of products from (1) monochlorobenzene and chloral, followed by reaction with methanol and (2) o-dichlorobenzene and chloral, followed by reaction with methanol, ethanol, propanol or isopropanol.

Abstract: 839,121. Load cells. COAL INDUSTRY (PATENTS) Ltd. June 17, 1957 [June 18, 1956], No. 18854/56. Class 40 (1). An electrical resistance strain gauge load cell is fitted with two sets of electrical strain gauges (active gauges and compensating gauges) and the compensating strain gauges are so arranged and so connected in the electrical circuit of the active gauges that the output signal of the cell is substantially independent of the manner in which the load is supplied to the cell. Fig. 1 shows a load cell (adapted for use with a pit prop by means of lugs F on plate A and cut out corners on plate B) in which the strain gauges are mounted on the sides of a cylindrical member D. The active gauges M are mounted axially and the compensating gauges N are mounted circumferentially with respect to the cylinder. The gauges are connected in a bridge circuit as shown in Fig. 2. It is stated that when a load is applied to the cylinder firstly in a generally distributed manner and then in a concentrated manner at the sides of the cylinder there are two regions in which the change in circumferential strain is zero and the compensating gauges should be situated near one of these regions. A method of locating a region of minimum circumferential strain is described in which three sets of " compensating " gauges are placed at different axial position on the cylinder. The strain at each of these points is measured and the position of minimum strain is extrapolated from the measurement. The Specification mentions that the compensating gauges may also give an automatic temperature correction.

Abstract: 426,239. Kinematograph apparatus. KODAK, Ltd., Kodak House, Kingsway, London.-(Assignees of Mihalyi, J.; 333, State Street, Rochester, New York, U.S.A.) Sept. 29, 1933, No. 19219 /34. Convention date, Oct. 1, 1932. Divided out of 426,208. [Class 97 (i)] A kinematograph camera or projector comprises mechanism for continuously feeding the film towards the gate, means for guiding the film in an arc which curves towards the entry of the gate in the direction of travel of the film therethrough, and mechanism for intermittently arresting and releasing the film on the entry side of the gate whereby during each stationary period of the film part within the gate the film on the entry side thereof is bent in the opposite direction and against its natural tendency to maintain the normal arc and forms a loop on the entry side of the gate, and when the film is released its natural resilience causes the part on the entry side of the gate to resume its normal arcuate form thereby feeding the film through the gate with a rapid snap-like action. As shown, the camera comprises a casing 1 with an objective 2 and divided by an internal partition 3 into a magazine chamber and a mechanism chamber housing a spring motor and gearing. A shutter arranged between the objective 2 and the arcuate gate 12 is reciprocated by a crank 10 and rod 11. The magazine comprises a base and spaced side walls 14, 16 forming a curved guide channel for the film F which tends to form an arc across the opening 15 and therefore the resilience of the film maintains it in engagement with the curved gate 12. The film F is fed from a spool 17 on a core 18 on a spindle 19 and is wound on a spool 20 on a core 21 rotated by a square spindle 22. A spring belt 26 passes round a pulley 27 on the spindle 24 carrying a gear 25 meshing with the gear 8 and also a feed sprocket 23, and also passes round a pulley 28 on the spindle 22. In the inner wall 16 are recesses 29, 30. A pivoted trigger 31 biassed by a spring 33 has a claw 35 bent to pass through an aperture 36 in the plate 3 and a slot in the magazine wall to engage successively the perforations in the margin of the film F. The gear 25 has a series of cams 37 successively engaging the end of the arm 34 of the trigger. When the claw 35 engages a film perforation, a loop is formed in the recess 30. On disengagement of the claw 35 through one of the cams 37 the film resumes the normal curvature f and feeds past the opening 15. The claw 35 re-engages the film and the cycle is repeated. Specifications 426,208 and 426,240 are referred to.
