Title: Improvements in or relating to the preparation of peanut protein
IPC: A23J1/14
Filed: 1943-12-06
Abstract: Peanut globulin is prepared from comminuted peanut material containing no appreciable amount of fragments of testa by treating the said peanut material with a dilute alkaline solution of such concentration that a pH of at least 11.0 is maintained during the extraction, separating the alkaline extract from undissolved matter and thereafter precipitating the globulins from the alkaline extract. It is preferable that the peanut material is substantially free of oil, before extraction.  The extraction may be effected by sodium hydroxide or potassium hydroxide solution which is preferably several times greater in weight than the peanut material, and which is preferably of such a strength that the globulin is not subjected to a pH greater than 11.5 for an appreciable time.  In the example, peanuts are crushed by passing them first through loosely set rollers and then through more closely set rollers, and the product is blown by a draught.  This is repeated with more closely-set rollers and the product placed on a vibrating screen while air is sucked through. The resulting testa-free material is extracted with petrol to remove oil and the petrol evaporated off.  The ground meal is then moistened with water and treated with sodium hydroxide solution.  The product after stirring, centrifuging and filtering is acidified with sulphur dioxide and the precipitated globulins washed with water. Globulins prepared in this way may be made into viscous solutions with sodium hydroxide which do not undergo surface gelation during a spinning process.  Specification 553,539 is referred to.

Patent GB-736596-A (GB)
Title: Improved lubricating compositions for use in drawing metals
Inventor: ERVINE WILLIAM DENIS
IPC: C10M173/00
Filed: 1952-08-19
Abstract: A lubricating composition suitable for use in drawing metals comprises a blend of a metal-drawing compound, in the form of an oil or grease containing an alkali metal soap of one or more animal fatty materials, with a soluble oil containing a lubricating oil together with one or more emulsifying agents, the amount of the drawing compound being between 20 and 55 per cent by weight of the total composition.  The composition is emulsifiable with water and, after its use in drawing metals, may be removed by simple washing with water.  The alkali metal soap employed in the metal-drawing compound may be derived from tallow or whale oil, for example by isolating the fatty acids and neutralizing these with a dilute alkali metal hydroxide such as potassium hydroxide. The lubricating oil employed in the soluble oil may be a hydrocarbon lubricating oil or a synthetic oil from any source, but mineral oils are preferred. Suitable emulsifying agents for use in the soluble oils are oil-soluble metal petroleum sulphonates or naphthenates, particularly sodium petroleum sulphonates.  The soluble oil may contain additional ingredients such as emulsion stabilizers (e.g. alkali metal or alkaline earth metal naphthenates, diethylene glycol or methyl, ethyl, propyl or butyl alcohol), anti-foaming agents (e.g. silicone oils or vegetable waxes such as candelilla wax), oiliness or extreme pressure agents (e.g. isopropyl oleate, tricresyl phosphate, chlorinated wax, fatty oils and sulphurized or phosphorized oils such as sulphurized sperm oil) and anti-corrosion additives (e.g. alkali metal benzoates).  The lubricating composition is preferably formed by working the drawing compound with the soluble oil, the drawing compound and the soluble oil being formed separately.  In an example, a drawing compound (prepared from tallow, whale oil fatty acids, potassium hydroxide and water) is blended with a soluble oil (prepared from mineral oil, sodium petroleum sulphonates, naphthenic acids, caustic soda, water, isopropyl alcohol, candelilla wax and chlorinated paraffin wax). Specification 689,740 is referred to.

Title: Television tuner channel selecting control apparatus
IPC: H04N5/44
Filed: 1973-05-03
Abstract: 1428556 Channel tuning arrangements; transistor pulse generators SONY CORP 3 May 1973 [8 May 1972] 21087/73 Headings H3Q and H3T In a television tuner channel selecting control system having a pulse generator 9 for producing a pulse signal of predetermined frequency in response to a control signal and, supplying the pulse signal to driving means 10 to drive a channel selecting means 11 step by step with an interval corresponding to the predetermined frequency of the pulse signal at positions of selected channels, an unrequired channel detecting means 12 for detecting an unrequired channel selected by the channel selecting means 11 actuates a frequency control 15 so as to increase the frequency of the pulse signal so as to pass quickly over the unrequired channels. An ultrasonic remote control signal such as 40 kHz, is received by a microphone 1 and is fed via an amplifier 2 and a detector 3 to set a bi-stable memory 4. This makes a transistor 5 non- conductive and astable multivibrator 9 starts to generate the predetermined frequency pulses. Each output pulse such as one every 0À5 s. from the generator 9 energizes a plunger of the drivmeans 10 which changes over the channel selected by the channel selector of the tuner 11 one at a time. When the moving contact 12a of the means detecting an unrequired channel which is stepped with the channel selector 11, contacts  selected channel fixed contacts 12b, 12c and 12d a transistor 15a remains non-conductive so that the pulse generator continues to produce pulses at the predetermined frequency until the control signal is removed whereon a reset generating circuit 16 resets the memory 4 and a transistor 5 conducts to stop the pulse generator 9. When the moving contact 12a contacts unrequired channel fixed contacts shown unconnected the transistor 15a conducts and modifies the time constant provided by a resistor 9c and a capacitor 9d so as to increase the frequency of the pulse generator 9, such as to one pulse every 0À1 s. This enables the channel selector 11 to rapidly skip the unrequired channel positions. When the control signal is ended after the channel slector 11 has selected an unrequired channel between contacts 12c and 12d, channel selection continues until the moving contact 12a contacts the fixed contact 12d whereon the reset circuit 16 resets the memory 4. This turns on the transistor 5 which inhibits the pulse generator 9 so that the channel selector 11 remains set to the required channel corresponding to the fixed contact 12d. Also unrequired channels can be automatically detected by the absence of a television carrier signal.
