Abstract: 382,528. Photographic cameras fitted with telemeters. DEHN, F. B., 103, Kingsway, London.-(Zeiss Ikon Akt.-Ges. ; 72, Schandauer Strasse, Dresden, Germany.) March 14, 1932, No. 7579. [Class 98 (i).] In a camera of the kind in which the focusing of the objective is controlled by a telemeter of the double-image or split-image type, a cam or cam groove moved with the objective during focusing effects movement of the adjustable part of the telemeter through transmission means which includes a second cam or cam groove. As applied to a camera fitted with baseboard focusing mechanism, the lens carrier a, Fig. 1, is fitted with a rail b carrying a cam c co-operating with a lug f on a spring-loaded lever d which turns on a pin s in the housing of a telemeter h disposed vertically in the camera body, and carries a cam disc k against which the lower, pivoted mirror g of the telemeter is pressed by a spring l. A similar arrangement may be used if the telemeter is one with an adjustable lens or prism, or has small matt screens for receiving the images. The lever d is automatically folded into the camera body when the camera is closed, and the cam c may be hinged about its vertical or horizontal edge for the same purpose. As applied to a camera having a lens in a focusing mount, the rotatable part of the mount m, Fig. 3, carries on its periphery a cam b<1> cooperating with a spring-loaded lever d<1> turning on a pin s in the housing of a telemeter h mounted on the lens carrier. A cam disc k on the lever d<1> actuates the mirror g of the telemeter as in the first construction. A modification of the second construction for inextensible cameras is referred to, in which the telemeter is arranged in the camera housing. The cams may be curved or straight, according to requirement. The telemeter, instead of forming a separate part, may be built into the camera housing or objective carrier. To compensate for wear, or to adapt the device for a change of camera lens or for fine compensating when using lens filters &c., the cams may be adjusted vertically or horizontally by screws, or the lug f may be adjustable, or the connections between the lever d and cam k may be adjustable. Interchangeable cams may be provided for use with different objectives. The device may be modified so that focusing is effected by operating the telemeter instead of operating the focusing mechanism of the lens. The Specification as open to inspection under Sect. 91 (3) (a) states also that if the cam b<1>, Fig. 3, is made sufficiently long, the second cam k is unnecessary ; and that when adjusting the telemeter for near objects, a special lens may be employed instead of adjusting the objective. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of aliphatic acrylic acid esters
IPC: C07C57/07
Filed: 1969-02-13
Abstract: 1,207,089. Acrylic acid esters. KNAPSACK A.G. 13 Feb., 1969 [17 Feb., 1968], No. 7885/69. Heading C2C. In a process for the preparation of aliphatic acrylic acid esters by the reaction of propylene and/or acrolein with oxygen in the presence of steam and inert gas at between 300 and 600‹ C. and in the presence of a catalyst the resulting reaction gas containing hot acrylic acid is scrubbed with a by-product high boiling organic solvent mixture, distilled and reacted in the presence of an acid ion-exchange resin with an aliphatic alcohol (1-8C). The product ester is distilled off and the high-boiling organic solvent mixture recycled to the acrylic acid scrubbing stage. Examples describe the oxidation of propylene using a silver, iron, bismuth, molybdenum, phosphorus and oxygen catalyst to a mixed product gas which is cooled and scrubbed counter-currently by a high boiler mixture of dimethyl maleate, polyacrylic acid and polyacrylates. The acrylic acid free residual gas from this stage is freed from formaldehyde and returned to the reactor, and the hot acrylic acid containing solution is supplied to a low-boiler distilling column to which stabilizer e.g. phenothiazine, is added. Acetic acid is withdrawn from the column head and the acrylic acid solution at the base is mixed with a 4% methanolic methyl acrylate solution and passed through a cation exchange column, and distilled at atmospheric pressure. The ion-exchange passage and distillation are repeated and the products combined and the base product of the final distillation is refluxed, to the gas wash tower. The preparation of butyl acrylate is also described as is the use of a cobalt molybdate catalyst in a similar process.

Title: Improvements relating to commutator motors
Inventor: TAYLOR PHILLIP LESTER
IPC: H02K23/18
Filed: 1962-03-02
Abstract: 980,957. Brushgear for electric motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 14, 1963 [March 2, 1962], No. 8230/62. Heading H2A. An arrangement for reducing the effects of friction between the brushes 4 and commutator 1 of an electric motor, e.g. in a servo mechanism comprises mounting the brushes in a brush, assembly so as to be able under the influence of the brush to commutator friction forces to move over a circular arc concentric with the commutator rotary axis to an extent limited by stops 7 which confine the movement to an arc within which commutation remains satisfactory. As shown, brush boxes 3 are mounted in a carrier 5 which is freely rotatable in a bearing 6 between the stops 7 which are either fixed or adjustable, so that for small motor movements the friction is zero and for larger movements the static friction is overcome by the impact of the carrier 5 against one or other of the stops. In Fig. 3 where the motor 10 is supplied with an error signal through a connection 17, the effect of rubbing friction is reduced by injecting into an amplifier 8 a potential from a source 14 or 15 as determined by contacts 11 ... 13 respectively mounted on the carrier 5 and stops 7. If the impact of carrier 5 is insufficient to eliminate static friction the circuit of Fig. 3 may be modified to assist this by increasing the potential of sources 14, 15 and introducing a current decay component, e.g. capacitor or inductor, in each connection to contacts 12, 13. To compensate for changes in the friction forces the stops may be resiliently mounted and arranged to control a transducer in the connection 16.
