Abstract: 1,215,060. Cooking salted meats. L. FERRARINI. 30 May, 1968 [28 July, 1967], No. 26013/68. Heading A2E. Salted meats, for example hams and shoulders of pig or other animal, are cooked by bringing the meat into contact with a heating medium for such a time until the loss of weight of the meat, with respect to its initial weight, being its weight as fresh meat after butchering and cutting up, but before processing, reaches a preestablished value, and then removing the meat from the medium and allowing it to cool. The Figure shows a suitable apparatus for carrying out the invention wherein a chamber 1 is provided with a water tank 3 fitted with an electric heater 4, a grill 5 permitting steam to enter the cooking zone. The meat to be cooked is placed in a mould 15 on the pan 3 of a weighing device, and the weight g is adjusted such that when the desired loss of weight has been achieved, the microswitch 12 switches off the element 4.

Patent GB-654015-A (GB)
Title: The manufacture of methyl lactate
IPC: C07C69/68
Filed: 1948-10-09
Abstract: A manufacture of methyl lactate comprises heating lactic acid and/or dehydrated lactic acid and methanol at a temperature between 180 DEG and 235 DEG  C. and at a pressure sufficient to keep a major part of the methanol in the liquid phase and maintaining the reaction mixture at said temperature between 30 and 60 minutes. The lactic acid may be anhydrous, dehydrated, i.e. consisting mainly of lactyl and higher polylactyl lactic acids, or contain water, e.g. up to 50 per cent by weight.  Acidic esterification catalysts such as boric, phosphoric, toluene sulphonic or sulphuric acids may be present.  Entraining liquids such as benzene and toluene present in dehydrated lactic acid are not objectionable.  The process may be carried out batchwise, but continuous operation is preferred.  In the latter lactic acid and methanol are introduced into a heated reaction zone, most conveniently a long, narrow tube of mild or stainless steel, the rate of flow being adjusted to give a residence time of 30 to 60 minutes. The methyl lactate may be recovered from the reaction mixture by usual methods, e.g. distillation.  Methyl lactate is obtained by the rapid fractionation of the products obtained in examples: (1) by passing a mixture of methanol and lactic acid of about 98 per cent concentration through heated mild steel coil under pressure; (2) by passing lactic acid containing 20 per cent by weight of water together with paratoluene sulphonic acid through the same heated coil under pressure.

IPC: G02B21/00
Filed: 1952-10-22
Abstract: 741,557. Optical apparatus. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Nov. 23, 1953 [Oct. 22, 1952], No. 26549/52. Class 97 (1). Apparatus for measuring the optical thickness of a transparent object comprises a microscope having means dividing the illuminating beam into ordinary and extraordinary beams so that one passes through the object and the other by-passes the object, and means for combining the beams which have respectively passed through and by-passed the object so that they interfere and an analysing apparatus for measuring the phase difference between the two beams. As shown, the illuminating beam 5 is divided by a birefringent plate 2, for example of Iceland Spar, into an ordinary beam 6 by-passing the object 1 and an extraordinary beam 7 passing through it. The planes of polarization of the beams are interchanged by passage through a half-wave plate 4 and they are combined by a birefringent plate 3 similar to the plate 2. The combined beams are reflected by a concave spherical mirror 9 and by a semi-reflecting surface 10 to form an image of the object at the pole of the mirror 9 which is observed by the microscope objective 11. An analyser in the eyepiece renders the interference effects in the image of the object visible. To measure the phase difference between the beams within the image and outside the image a halfwave plate in the form of a narrow strip 12 is located in the image plane of the objective 11 with its principal directions coinciding with the planes of polarization of the beams 6 and 7 and extending into the field beyond the image of the object 1. A quarter-wave plate 13 converts these beams into circularly polarized beams with opposite senses of rotation the result being a linearly polarized beam the direction of polarization of which depends on the phase difference between the beams 6 and 7. An analyser 14 is provided, rotatable about a vertical axis, and is rotated until the intensity within the strip is equal to that outside the strip first for the portion of the strip covering the image and then for the portion extending into the field, the difference between the angular rotations of the analyser 14 indicating the optical thickness of the object. In a modification a quarter-wave plate is placed above the objective and the strip 12 replaced by a half-wave plate in the form of a lattice, a rotatable analyser again being provided.

Abstract: 816,192. Driving apparatus for endless conveyers. DEMAG A.G. Aug. 23, 1957 [Sept. 14, 1956], No. 26707/57. Class 78 (1). A driving unit for an endless conveyer used in underground mining consists of two or more motors each driving a free member of a planetary gearing the output of which drives the conveyer. As shown, motor 1<SP>1</SP>, of short-circuit rotor type, drives a sun-wheel 2<SP>1</SP>, while another motor 41, also of short-circuit rotor type and of smaller power than the motor 1<SP>1</SP>, drives through a pinion 5<SP>1</SP> an annulus 6<SP>1</SP>. Planet wheels 3<SP>1</SP> on a carrier 7<SP>1</SP> engage the annulus 6<SP>1</SP> and the sunwheel 2<SP>1</SP>. Upon either motor being operated, the carrier 7<SP>1</SP> is driven, this driving an output shaft 10<SP>1</SP> via bevel gearing 81, 9<SP>1</SP>. The arrangement is such that the ratio of the speeds of shaft 101 corresponding to one or other motor being operated is the same as the power ratio of the motors. The motors have automatic brakes 11<SP>1</SP>, 121 respectively, and are reversible so that they may be operated together in opposite or the same direction to give further speed ratios. Each of the brakes 11<SP>1</SP>, 12<SP>1</SP> is sufficiently powerful to hold the associated motor stationary while the other motor is driving the conveyer at normal speed but is designed to slip during starting of the other motor so as to reduce starting torque.
