Title: Improvements in or relating to piezo-electric devices
IPC: H04R17/00
Filed: 1928-10-15
Abstract: 298,904. Russel, E. W. C., (Assignee of Sawyer, C. B.). Oct. 14, 1927, [Convention date]. Piezo-electric instruments.-A piezo-electric unit used as the energizing-movement of a loud-speaker comprises two crystal sections 13, 14 so cut from the mother crystal that under the action of an applied potentialdifference one section expands longitudinally whilst the other contracts, thus exerting a torque tending to impart transverse vibrations to the diaphragm 3. The activating potentials are applied from leads 21, 22 across a central rib 7 and tinfoil electrodes 18, 19 covering the external surface of the crystal sections. In assembly, the crystal sections of Rochelle salt &c. are inserted between the upper and lower abutments 10, 9, 11, 12, and cemented say by a copper mercury amalgam, so that they are normally held under longitudinal tension. This may be effected either by stretching the central rib 7 prior to inserting the crystals, or by assembling the device at a low temperature. This minimizes the effect of the varying co-efficients of expansion of the crystal and its supports. The supporting frame and rib 7 are preferably made of aluminium, magnesium, or similar light metal having a high co-efficient of thermal expansion. The movement is bolted to a block 17 of lead or other heavy metal.

Patent GB-483925-A (GB)
Title: A method or process of manufacturing sausages and sausage-filling composition
IPC: A23L13/40
Filed: 1936-11-04
Abstract: A sausage-filling composition, from which smoked and/or cooked sausages can be prepared which are substantially free from casing wrinkles, internal voids and free moisture, is prepared by adding to the meat constituents sufficient of an edible water-absorbent vegetable gum to constitute 1/4 -3 per cent by weight of the mixture, the mass being intimately mixed at a low temperature at which the gum constituent only absorbs such a proportion of water and juices from the meat that the composition will be of a consistency to enable it to be readily introduced into sausage casings, so that the gum constituent will be capable of further absorption of water and juices from the meat and of attaining a jelly-like condition when the composition is brought to or maintained at a temperature of about 140 DEG  F.  Preferably agar agar to the amount of 1/4 -1 per cent is used but 1/2 -2 per cent of gum tragacanth or 3/4 -3 per cent of gum arabic or Karaya or locust gum, may alternatively be used. Mixtures of gums may be employed.  The meat constituents consist of meat chunks and trimmings, raw or cured, to which may be added a cereal e.g. wheat or corn flour or soya or buckwheat flour or mixtures thereof as a filler, curing salt or common salt, and flavouring ingredients consisting usually of spices, peppers, spice essences, spice oils, and/or oleoresins of peppers.  The temperature may be reduced by adding broken ice to the amount of 25-100 per cent of the weight of the meat, the mixture being treated in a chopper.  Agar agar when used in preferably first mixed with the filler.  The sausages may be smoked at 140-145 DEG  C. and, if desired, cooked at 155-175 DEG  C. and suddenly cooled as by application of cold water, on which the gum sets to a jelly.

Title: Process for discharging dyeings on wool
IPC: D06P5/13
Filed: 1934-10-19
Abstract: Printing.--In discharge printing of dyeings on wool by means of sulphoxylates the deleterious effect on the wool of sulphide decomposition products of the sulphoxylates is avoided by incorporating in the discharge paste a salt of a chloracetic acid. Hygroscopic agents such as glycerol, thiodiglycol or urea and zinc oxide or lithopone may advantageously also be incorporated.  The following examples are specified.  (1) A woollen fabric, dyed with a dischargeable dyestuff, is printed with a discharge paste containing sodium sulphoxylate, zinc oxide, glycerol, sodium monochloracetate, urea and British gum thickening and the printed material is steamed for 5--6 minutes and washed.  (2) Wool fabric is treated as in (1) with the omission of the urea from the paste. (3) Chlorinated wool, dyed with a dischargeable dyestuff, is printed with a discharge paste containing sodium sulphoxylate, zinc oxide, thiodiglycol and alkali salts of a technical mixture of mono-, di- and tri-chloracetic acids and the printed material is steamed for 4--5 minutes, washed and lightly soaped at 50 DEG  C. (4) A woollen fabric, dyed with Benzyl bordeaux B is printed with an aqueous discharge paste containing sodium sulphoxylate, zinc oxide, glycerol, titanium white, sodium monochloracetate, Quinoline yellow and gum arabic and the printed material is steamed for 5 minutes and washed to obtain a yellow discharge on a red ground.
