Title: Improvements in the storage and handling of chemical substances
Inventor: TIBBS GEOFFREY THOMAS
IPC: C08L81/00
Filed: 1965-01-23
Abstract: Active chemical materials, which when mixed form adhesives, sealing compounds &c., are packaged in a single container in three or more layers, at least one of the active materials being divided into two portions, one of the portions being mixed with a thixotropic or gelling agent, or a retardant, to separate the other portion from the second active material. The other portion or the second active material may be mixed with an accelerator. The layers may be arranged vertically, horizontally, or as concentric cylinders within the container, e.g. a tin or bottle. A mixing device may also be incorporated in the package. Alternatively, the container may be a flexible sausage-like skin, the contents being mixed by manipulating the container before extruding the contents. In an example of a sealing or adhesive composition, a polysulphide material, "\sHThiokol L.P.33," (Trade Mark), is packaged with an epoxy resin, "Epikote 828", (Trade Mark).  The polysulphide is mixed with gelling agents comprising finely divided silica, and surface coated calcium carbonate, and divided into two portions.  An accelerator, tri(dimethylaminomethyl) phenol is added to the outer layer-forming portion. The third layer is formed by the epoxy resin mixed with surface coated calcium carbonate.

Title: New chlorinated bicycloheptenes, and fungicidal compositions containing them
IPC: C07C17/30
Filed: 1960-01-29
Abstract: The invention comprises compounds of the formula:  <FORM:0868910/IV (b)/1> where X and Y are chlorine or hydrogen atoms and R is a hydrogen atom or a methyl group.

Title: Process of preparing active substances from hypophysis glands
IPC: A61K38/22
Filed: 1929-02-04
Abstract: 305,475. I. G. Farbenindustrie Akt.- Ges. Feb. 4, 1928, [Convention date]. Medicines for internal use.-Active substances are obtained from the fresh or dried whole hypophysis, without previous separation of the two lobes, by hydrolysis by means of an alkali or an acid, conditions as to time and temperature being controlled so as to avoid decomposition of the active substances. The process may be carried out in steps so that the various active substances are separately obtained. Albumin degradation products are precipitated by adjusting the hydrogen ion concentration of the ,solution. A water-soluble organic solvent may be added to the solution to precipitate further impurities. According to examples, (1) fresh whole hypophysis is ground in water, hydrochloric acid gas is passed for 30 minutes at 15‹ C. and the mass centrifuged, these operations are repeated, and the combined liquids are neutralized with strong caustic soda solution and centrifuged and, if desired, further purified by addition of acetone; (2) dry powdered whole hypophysis is treated with N/2 caustic soda for 20 minutes at 35‹-40‹ C., centrifuged to obtain a liquid containing the active substance of the posterior lobe, and the remaining solid is repeatedly treated with N- caustic soda each time for 20 minutes at 25‹ C. to obtain a second liquid containing the active substance of the anterior lobe, the two liquids. separately or mixed together, being neutralized with 2-N-hydrochloric acid to precipitate ballast substances; (3) a mixture of the anterior and posterior lobes of the hypophysis is extracted with 3 per cent sodium sulphide solution for 20 minutes at 15‹ C., the extract is centrifuged and neutralized, these steps are repeated, the combined liquids are adjusted to PH5 to precipitate albuminous substances, and hydrogen sulphide liberated is eliminated by any usual process not involving heating. Various concentrations of caustic soda, and of hydrochloric acid, are referred to as hydrolysing agents. The Specification as open to inspection under Sect. 91 (3) (a) refers also to treatment of the separated parts of the gland in the manner above set forth and to the use of sulphuric acid as a hydrolysing agent. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for generating electric oscillations and for controlling the frequency of such oscillations
Inventor: FOOT JOHN BARTRAM LOVELL

Filed: 1956-02-08
Abstract: 806,529. Automatic frequency control systems. GENERAL ELECTRIC CO. Ltd. May 8, 1957 [Feb. 8, 1956], No. 4003/56. Class 38 (4). In an automatic frequency control system for an oscillator 3, as in Specification 666,088, employing continuously running synchronous motors 14, 15 acting on a tuning shaft of the oscillator through a differential gear 16, the motor speeds being determined by low-frequency oscillators 17, 18 whose frequencies are controlled in opposite senses from a frequency discriminator 24 with a pair of balanced outputs a relay A is de-energized when the strength of the reference oscillations frequency-changed at 1, amplified at 4 and limited at 23 falls below a predetermined value, this causing contacts A1 to fall back and close so that the discriminator outputs have the same value, the oscillators 17, 18 the same frequency and tuning ceases. Output of a frequency modulated reference oscillation received from an aerial 2 may be taken from a discriminator 9 fed from a narrow band amplifier 7 (therefore less responsive to noise) and also controlling the frequency of local oscillator 6, frequency changing the input to the amplifier 7. During fading the control of local oscillator 3 by the wider band discriminator 24 ceases and oscillator 6 tends to follow any drift of oscillator 3 but as this involves a positive or negative input to a reactance valve controlling oscillator 6 a polarized relay B is correspondingly actuated and contact B1 applied to earth either resistor 28 or 29 associated with R-C oscillators 17, 18 to charge the frequency of one and apply differential drive to the motors 14, 15 to counteract any drift by oscillator 3. When, however, the received. signal is very weak a relay C associated with limiter 8 preceding discriminator 9 is released so that contact C1 closes and the grids of oscillators 17, 18 are connected together, making their frequencies identical so that any differential drive to the motors ceases. But first this is conditional on the phases of the applied drives from amplifiers 19, 20 being equal, otherwise a relay D, responsive to any difference in phase, opening a contact D1 in series with contacts A2, C1. The relay A may be operated from an anode circuit of limiter 23 tuned to a frequency band different from that of the discriminator 24, i.e. sensitive to noise which, on increasing above a predetermined level due to fading of the signal, provides a rectified output biasing off a valve having the relay A in its anode circuit, i.e. releasing the relay A so that contact A1 closes. The system may be applied to a U.H.F. receiver using scatter radiation.
