Patent GB-1056175-A (GB)
Title: Improvements in or relating to the production of waxes
IPC: C08F10/02
Filed: 1963-10-02
Abstract: Waxes are produced by polymerizing ethylene in the presence of a catalyst comprising a compound of the formula AlR2Hal, AlRHal2 or Al2\R3Hal3 in which R is an alkyl or alkoxy group and Hal is halogen, and also comprising a 4.valent titanium halide, the atomic ratio of aluminium to titanium being at least 1:1 with the polymerizate being kept in the fluid state at a temperature between 130 DEG  and 240 DEG C. and in the presence of hydrogen in a concentration of up to 70% in the gaseous phase.  Polymerization is preferably effected in the presence of an inert non-aromatic organic solvent such as petroleum ether.  In the examples the catalyst, which comprises titanium tetrachloride and aluminium diethyl chloride, is heated in petroleum ether under nitrogen before the introduction of ethylene and hydrogen. Small amounts of propylene and/or n-butylene may be copolymerized with the ethylene.  In one example the process is continuous. The wax formed is treated with a dilute aqueous sodium hydroxide solution, washed, and then steam distilled to remove the solvent.  The waxes may be oxidized with air either before or after removing the catalyst residues, which in the former case may be after treating the wax with sodium hydroxide but before washing out the aluminium and titanium hydroxides so formed.  Solutions of the waxes may be cooled to precipitate out high melting point waxes.

Title: Intrusion detector radar system
IPC: G01S13/56
Filed: 1968-08-16
Abstract: 1,205,153. Intruder alarm system. BOEING CO. 16 Aug., 1968 [2 Oct., 1967], No. 39364/68. Heading G4N. [Also in Division H4] An intruder detection alarm system in which an intruder within the area of surveillance disturbs an electromagnetic field comprises (see Fig. 3), a pulse modulator 14 which controls the duration of the signal pulses derived from oscillator 10 and sent out by transmitter 12. Any object between 12 and receiver 16 will reflect the signal such that at 16 both direct path and reflected signals will be received. If the object is in the surveillance area then the reflected pulses will arrive before the end of the direct path pulses and the latter having biased the detector 40 open, an output results which triggers gate generator 44 and provides the second input to coincidence detector circuit 46. The first input of 46 is the combined signal from detector 42. The output of 46 is passed to an averaging circuit 48 and then to a detector 50 which produces an output to alarm 28a when the output of 48 changes, i.e. when an object moves within the surveillance area. In Fig. 1, a mixer circuit combines the two signals producing a difference frequency output. A small fast moving object, e.g. a bird, will produce a high frequency shift due to the Doppler effect and the relatively high difference frequency is blocked by a low-pass filter such that maloperation of the alarm does not occur. The change in input signal due to the movement of an intruder is detected by a detector 26 which controls alarm 28. In Fig. 5 (not shown), the circuit of Fig. 3 is modified to include a differentiating circuit between the detector and gate generator which produces a sharp pulse input to the latter and which also has a control that alters the duration of the signal to the coincidence detector circuit and hence the area of surveillance.

Patent GB-1531261-A (GB)
Title: Computer store mechanisms
IPC: G06F12/08
Filed: 1975-09-27
Abstract: 1531261 Data processing systems NATIONAL RESEARCH DEVELOPMENT CORP 22 Sept 1976 [27 Sept 1975] 39647/75 Heading G4A Data processing system includes a processor P accessing a hierarchical storage system via an access controller C. The storage system includes a main store MS and a buffer SS, the latter storing each word, data or instruction, accessed from the main store by the processor, in successive locations cyclically under the control of a discard address register whose contents are incremented after each access, words previously stored in the buffer being replaced in the main store and overwritten as necessary. Means are provided when accessing the buffer to check whether the required word is present in the accessed location or has been overwritten. The buffer includes in each location, a field for a word, a field for the main store address of that word, two fields for the buffer store addresses of associated words, specifically in the case of an instruction its operand and the next instruction in sequence to enable these words to be accessed directly from the buffer if they are present, and certain flag bits. When a word is stored in the buffer its buffer address, i.e. the current contents of the discard address register, are stored in its place in the main store so that to determine whether a word is in the buffer the main store is addressed and the appropriate bits of the resulting word used to access the buffer to provide, from the appropriate field, a main store address which is compared with the address used to access the main store. Equality indicates that the word is in the buffer. Alternatively an extra bit in each main store location is used to indicate when a word is in the buffer. The discard address register includes an extra bit whose state is changed after each complete cycle of buffer addresses has been run through. This bit is loaded in the appropriate flag locations in the buffer, e.g. when an instruction requires an operand, the bit is stored in both the instruction and operand locations in the buffer so that when the operand is accessed the relevant bits are compared to check that the operand is the correct one and has not been overwritten. In a modification certain tag bits are replaced, the checks been made by computation in the processor using the buffer addresses of the words involved and the contents of the discard address register. The Specification gives full details of the operations performed when the various storage operations are performed. It is stated that three levels of storage, e.g. semiconductor, magnetic core, and magnetic drum may be provided.
