Title: Improvements in ion exchange membrane electrode and method of forming
IPC: C25B9/23
Filed: 1965-09-24
Abstract: A process for applying an electrode of a catalytically active metal to an ion-exchange membrane comprises electrolytically depositing a thin layer of catalytically active noble metal on to an electrically conducting base e.g. of stainless steel, washing the deposit to remove the residue of the deposition bath, drying the washed electro-deposited catalytic metal, placing an ion-exchange membrane in contact with said electro-deposited metal, applying heat and pressure to the assembly to bond the catalytically active metal to the ion exchange membrane, and removing the ion exchange membrane, with the layer of electro-deposited metal attached, from the conducting base.  The catalytically active metal may be applied in the form of an alloy with a non-catalytic material which is removed by etching prior to the application of the ion-exchange membrane. Specified catalytically active metals are platinum, palladium, indium, rhodium and ruthenium.  In examples, Pt black is electro-deposited from an aqueous solution of chloroplatinic acid containing a small amount of lead acetate; Pd is deposited from a chloride solution, as also is an Pd-Ir alloy; a Pt-Rh alloy is deposited from a heated solution of the chlorides containing also NaNO2 and to which ammonia is added; while a deposit of Pt black is obtained by electro-depositing a Pt-Ag alloy from a bath containing chloroplatinic acid, silver chloride, lithium chloride, and hydrochloric acid and removing the silver by dipping the plated base in nitric acid. Specified membranes are made from sulphonated styrene polymers and a mixture of polyvinylidene fluoride and polytrifluorochloroethylene which may be swollen prior to contact with the noble metal coating, copolymers of styrene and vinyl benzene, zirconia and calcin-doped zirconia.  Additional quantities of the noble metals or of different metals may be coated on to the outer surface of the first coating.  Expanded metal screens formed of Pt, Ta, Au, or Ti containing 2% Pd or a layer of Au powder bonded with PTFE may be placed against or bonded to the noble metal as current collectors. The assemblies may be used in gas purification cells in which gas e.g. hydrogen supplied to one electrode is transported via the electrolyte and released at the opposite electrode.

Title: Improvements in or relating to meat products
Inventor: BEUK JACK FRANK
IPC: A23L13/70
Filed: 1958-12-30
Abstract: The distribution of tenderizing enzymes in meats is effected by introducing a proteolytic enzyme in a liquid medium into the vascular system of a living animal from which meat is to be obtained, and then slaughtering the animal after a period of time sufficient to permit substantially uniform distribution of the enzyme throughout the animal's body but before the presence or effectiveness of the enzyme has, been eliminated by the animal's body processes.  The enzymes are exemplified by papain, bromelin, ficin, trypsin, pancreatin, some cathepsins and milkweed proteinase.  The enzyme may be stabilized, i.e. preserved in a condition permitting injection without causing undesired physiological reactions in the animal or lesions in the viscera or carcass, such preservation being accomplished by reversible inactivation of the enzyme involving addition of inactivating materials or removal of activating materials.  The enzyme may be purified.  Suitable aqueous enzyme solutions are the subject of Specification 913,203.  The amount of enzyme preparation introduced may be sufficient to distribute 0.5-150 mg. of enzyme per pound live weight of the animal.  The animals concerned are meat-bearing ruminants, hogs and poultry.  In Example I is described needle-injecting a preparation of papain in glycerol and physiological saline by the jugular vein into ewes preliminarily treated to cut off circulation to one hind leg, killing the ewes 3 minutes after completion of the injection, removing the hind legs and roasting them for comparative tests of tenderness by a panel. In Example II is described needle-injecting old roosters by the humeral vein with a papain solution, killing the birds 5 minutes after the injection, dressing and cleaning the birds, chilling them for 24 hours, roasting them and testing the roasted birds for tenderness by a panel.

Title: Data transmission method and apparatus
IPC: H04B7/26
Filed: 1972-09-12
Abstract: 1409060 Selective signalling MARTIN MARIETTA CORP 12 Sept 1972 [25 Oot 1971] 42312/72 Heading G4H [Also in Division H4] A plurality of transmitters spaced through a geographical area each transmit the same address without transmitter interference by transmitting using mutually-exclusive time slots, a plurality of portable receivers being provided to receive the address. Further transmitters can use the same time slots provided no two transmitters using the same time slot have propagation areas which overlap. In a paging system, the address (identity) of a portable radio receiver to be paged is dialled through the telephone system to a central station which includes a computer which, after validity checks stores it in a queue (unless it is there already). A message word is constructed from 30 addresses from the queue (or less plus dummy addresses) each in Bose-Chaudhuri code with or without a parity bit, preceded by and separated by various types of sync pattern. The message word is sent to and transmitted by various ones of the transmitters in respective time slots of a major data frame, subject (at each transmitter) to a valid sync check using a bi-directional counter. The transmitters can also transmit in a "tone" mode in which all the transmitters transmit together, apart from fixed relative delays intended to equalize reception times. The transmitters determine which mode to use from differences in the sync patterns used, or other codes. Each receiver, if it receives the sync patterns preceding the addresses in a given time slot substantially without error (determined using a bi-drectional counter), decodes the addresses in that time slot (using comparison with addresses from fused diode matrices, and counting) and the de-energizes for 7 seconds i.e. until the corresponding time slot in the next data frame (since each frame is 8 time slots, of one second each). If the receiver recognizes one of the addresses, it gives an audible (tone or enunciated message) and/or visual indication. A receiver may correspond to two addresses to indicate origin of the page (e.g. home or office) or degree of urgency, giving different tones (or a steady and an interrupted tone).

Title: Discrete polyurea microcapsules
IPC: B01J13/16
Filed: 1976-10-13
Abstract: Polyurea microcapsules having individual capsule walls are produced. The capsule walls are obtained by interfacial polymerisation. Firstly, an organic phase is formed, which contains water-immiscible material to be encapsulated, a solvent which is capable of excluding water from the organic material and/or of controlling the porosity of the polyurea wall in accordance with the solubility parameter for the polyurea microcapsule wall, and a polyisocyanate. This organic phase is dispersed in an aqueous phase which, in addition to water, contains a surfactant and a protective colloid. The individual polymer walls of the capsules are then formed. This process allows the quality, in particular the porosity and thus the permeability of the capsule walls to be controlled.

Abstract: 1,071,916. Pressure transducers. CESKOSLOVENSK‡ AKADEMIE VED. Oct. 19, 1964 [Oct. 31, 1963], No.42519/64. Heading G1N. [Also in Division H3] High frequency heating current is applied to a ferroelectric capacitor forming part of a resonant circuit so that the capacitor is heated to the so-called "autostabilizing state" (detailed in Specification 1, 049, 613) in which variations of the dielectric constant with temperature are at a maximum and the capacitor becomes stabilized at a value such that the applied heating frequency is at a point on the sloping flank of the resonance curve. Acoustic or other pressure changes on the dielectric substantially parallel to the heating electric field, therefore modulate Piezo-electrically the heating current so that, with a diode detector a dielectric modulation frequency amplifier is formed. The dielectric may form part of a microphone or gramophone pick-up, and may be biased by a D. C. source varying the working point and therefore the amplification. Two electrodes on one face of the dielectric may co-act with an opposite pressure sensitive electrode so that two series capacitors in effect are formed. The heating current may be adjusted by a series capacitor. The dielectric may be triglycine sulphate.
