Title: Improvements in or relating to hydrocarbon chlorination
Inventor: OBRECHT ROBERT PAUL
IPC: C07C17/00
Filed: 1957-07-01
Abstract: Carbon tetrachloride, perchlorethylene or mixtures thereof are prepared by treating an organic compound having one to three carbon atoms and being a saturated aliphatic hydrocarbon, a partially chlorinated saturated aliphatic hydrocarbon or an olefinic hydrocarbon with an amount of chlorine in excess of that required to give a perchlorinated compound and in the presence of a coolant consisting of carbon tetrachloride, perchlorethylene, hexachlorethane, hexachlorobutadiene or mixtures thereof.  The reaction is carried out at a temperature between 450 DEG  and 800 DEG C. and is characterised in that a sufficient quantity of the components introduced into the reaction zone are in a liquid form so that they take up the heat of reaction of the chlorine and the compound to be chlorinated to a sufficient extent to maintain the temperature of the reaction zone within the desired limits.  The hydrocarbon feed is preferably propane or a mixture of hydrocarbons and/or partially chlorinated hydrocarbons may be used instead of a single compound.  The liquidvapour mixture fed to the reaction zone may contain some or all of the coolant in a liquid form and some or all of the chlorine or hydrocarbon feed may also be fed in a liquid form if desired.  Consideration is given in the Specification to the effect that reaction conditions and reactant ratios have on the ratio of carbon tetrachloride to perchlorethylene in the reaction products and also on the formation of hexachlorethane and hexachlorobenzene. In the Examples 1-9 in which propane or propylene is chlorinated at 550-600 DEG  C. in the presence of (1-6) liquid coolants and (7-9) liquid-vapour coolants the reaction conditions and reactant and product compositions are tabulated.  Specification 820,849 and U.S.A. Specifications 1,930,350 and 2,305,821 are referred to.

Title: Extruder head for forming hollow plastic products
IPC: B29C48/10
Filed: 1961-06-08
Abstract: <PICT:0932157/IV(a)/1> <FORM:0932157/IV(a)/1> An extrusion head for forming tubes of plastic material admits plastic to flow therein initially in a first circular flow path 48 in a plane normal to and nearly completely around the axis of the die aperture and redirects it at one side of and throughout this path at a right angle turn via a restricted annular passage 66 into an annular flow path 50 about the die axis leading to the die aperture so as to achieve uniform flow which yields a product free from surface blemishes.  In the extrusion head illustrated passage 26 delivers plastic material from an extruder to the head 20 which comprises body 28 and ring formation 30 together forming die aperture 34 and flow passage 36.  The plastic material flows initially in the circular flow path 48 in the direction of arrows 60 in plane P normal to the die aperture axis X. Hands 68, 70 form constricted flow path 66 in the form of a gap of varying width counterclockwise from A to D (being in contact from D to A). Plastic material is thus also displaced through path 66 throughout its extent in circular path 48, the graduation in width ensuring delivery of the material into the annular path 50 (in which the material flow is substantially radially inwards) at a substantially uniform rate and subsequently the material is delivered uniformly to the die aperture 34.  Relief passage 74 may be provided to achieve optimum uniformity of flow.  Heating unit 90 may be provided and conduit 37 may be used to inflate the extruded tube in known manner.  An alternative embodiment may be used for coating cores (Fig. 11, not shown).

Title: Vertical reheating furnace and method of operating same
IPC: C21D1/74
Filed: 1961-06-12
Abstract: A method of heating metal articles consists of heating the article to a temperature at which scale is not formed in a preheating chamber, and completing the treatment in a treatment chamber containing a protective gas by heating both sides of the walls of the chamber so that enough heat is stored in the walls to finish the treatment by radiation.  The treatment chamber 1 and the preheating chamber 11 are both heated before the charge 17 is inserted, the combustion gases passing down from the burner outlets 2 to the exhaust ducts 3 and into the space 8 surrounding the treatment chamber wall <PICT:0984223/C6-C7/1> 6, then through ducts 9 and 13 and 10 and 14 into a space 12 surrounding the preheating chamber, whilst the dampers 22 are open and dampers 21 are closed.  When the furnace is heated up, the charge is inserted into the preheating chamber and the dampers 21 are opened, allowing the exhaust gases to pass through a recuperator 18.  With the treatment chamber at the working temperature, the charge is transferred thereto, dampers 22 are closed, the burners are turned off and the heating of the charge 17 is completed by the heat residing in the wall 6.  Protective gas is pumped into the treatment chamber through a tube 4 and any combustible component is burnt off at 5.  A second charge is inserted into the preheating chamber at the same time, and the process is repeated.

Title: Electrical information store
IPC: G11C14/00
Filed: 1975-05-20
Abstract: 1516134 Transistor storage circuits PLESSEY CO Ltd 14 May 1976 [20 May 1975] 21367/75 Heading H3T In an information storage device utilizing MNOS transistors T11, T21, the control circuit for these transistors comprises series RC circuit R, C1 the input terminals t1, t2 of which can be selectively connected to either pole of a power supply 3, 6 and the output terminal of which t3 is connected to the gates of T11, T21; and a device 9 is connected across the supply terminals to protect the transistors if the supply is connected the wrong way round. The MNOS transistors T11, T21 have variable thresholds, and provide retention of the stored data in the event of power failure. The terminals t1, t2 are connected to the supply terminals by means of gates (not shown) controlled by appropriate gating pulses to give erase, write or read operation in respect of data at d13, d23. For example, as shown in fig. 2, assume that terminal tl is initially at the potential of line 3 (earth) and that terminal t2 is at the potential of line 6 (negative for p-type conductivity transistors). If t2 is pulsed to earth, RC I will differentiate this pulse to produce at t3 a short positive (erase) pulse followed by a short negative (write) pulse. If ti is pulsed negative RC1 will integrate this pulse to produce a long negative (read) pulse. Other sequences of switching between the levels may be used to provide the three types of pulses Figs. 3, 4 (not shown). In order to protect the drains of the transistors T 11, T21 during an erase pulse, and to inhibit writing when not required, the drains may be connected via further transistors (T14, T24 Fig. 6 not shown) to an auxiliary supply (V TT ) instead of to the drain supply of T 12, T22 and the gates of these further transistors are connected to receive the voltage at terminal t 2 . A further embodiment Fig. 7 includes additional circuitry providing indication of whether information being registered in the store is the same as that already stored or not. A strobe pulse enables transistors Tl, T15, T25 and if the data presented is the same as that already stored transistor 15 conducts and the potential at the gate of T2 is low. If the data differs, then the potential at the gate of T2 is high. T4 operates similarly in respect of another memory cell and with a low potential at the gates of both, coincidence is indicated by the potential at the source of T3. (For figures see next page)
