Title: Process for preparation of a vaccine for the treatment of paralyses following on poliomyelitis
IPC: A61K39/116
Filed: 1952-10-09
Abstract: A vaccine for the treatment of paralysis following on poliomyelitis is prepared by cultivating separately in a medium containing an emulsion of spinal or brain marrow, germs taken from (a) the nasal passages (b) the throat and (c) the rectum of patients paralysed with poliomyelitis in admixture, for the two first cultures, with diphtheria and para diphtheria bacilli and Hemophilus pertussis, while typhoid and paratyphoid, dysentery and paradysentery bacilli are added to the germs from the rectum, the said different germs being then killed, whereupon the three cultures are mixed, the mixture containing substantially equal amounts of the three types of killed germs and the treatment of the said mixture being that conventionally adopted for obtaining vaccines.  The medium may be gelatin in meat broth containing 10 per cent. of spinal or brain marrow and 2 per cent. agar-agar. The cultures are kept at 35 to 38 DEG C. for 4 to 6 days, the germs killed at 56 to 65 DEG C. and 0.50 per cent. solution of phenol added as preservative.  A vaso-dilator such as histamine is added to the vaccine.

A coder for pulse amplitude modulated signals comprising a plurality of series connected stages 111, 121 .. 191 (Fig. 3), each including a source of bias voltage which may modify the input signal before it is fed to the next stage includes pulse-shaping circuits 112, 122 . . . 182 between some of the stages. In the embodiment described in which a reflected binary output pulse train at terminal 199 is obtained via delays 113, 123 ... 183, each pulseshaping circuit includes a sampling circuit receiving a source of timing pulses and a holding circuit. Each coder stage includes a comparator which determines the polarity of the input signal and delivers the bit of the digital signal associated with the stage, a rectifier which delivers a negative output, a positive source of bias voltage and an amplifier with a gain of approximately two. Preferably the amplifier which may include a resonant circuit is chosen to have a gain of more than two for low frequencies to reduce the time interval taken for the amplifier output to reach its ideal value. The input to the amplifier may also consist of the original input pulse together with a pulse obtained by attenuating and delaying this pulse (Fig. 13, not shown).

Abstract: 1352784 Magnetic separation, tube mills BAYER AG 19 April 1971 [28 March 1970] 25418/71 Headings B2A and B2J In a process for the separation of magnetisable particles from a material in the course of size reduction during a grinding operation. after grinding, the material is separated into fine material and gravel by, say, centrifugal air separation and following separation of the magnetisable particles from the gravel by a magnetic separator the gravel-like material is returned to the grinding step. As shown, material such as titanium slag or mixed magnetic and non-magnetic ores is fed from a hopper 1 to a grinding mill 4 which is charged with balls of different diameters. Size reduced material from the mill is blown with preferably hot air to a separator 5 where the gravel constituent is separated out and fed to a magnetic separator comprising a rotating magnetically induced drum 8 and a brush 9. The magnetisable material is delivered to a container 11 whereas the non-magnetic gravel is returned by a return screw 12 to the mill 4. The fine material which passes through the separator 5 is separated from the carrier air in a cyclone separator 14 and fed to a conveyor screw 15 for delivery at 16.

Title: Gain Controlled Amplifier
IPC: H03G1/00
Filed: 1967-06-01
Abstract: 1,181,124. Gain control in transistor amplifiers. RCA CORPORATION. 1 June, 1967 [13 June, 1966], No. 25458/67. Heading H3T. A forward-acting gain control voltage is applied from A.G.C. amplifier 52 to the gate of a field-effect transistor 10 acting as R.F. amplifier in a radio receiver. By-passed resistors 28, 36 are connected respectively in source and drain circuits and provide connection points for the emitter and collector respectively of an NPN transistor 48, the base of which is connected to the A.G.C. amplifier 52. Below a predetermined value of A.G.C. voltage transistor 48 is cut off, due to the reverse bias derived from the voltage drop across resistor 28: for greater values, however, the transistor is conductive and clamps the source to gate voltage of field-effect transistor 10. The gain beyond this point is reduced by the shunting effect of the emitter to collector path of transistor 48 on the D.C. supply to the field-effect transistor 10.

Abstract: 768,656. Combustible processes. BADISCHE ANILIN- & SODA-FABHIK AKT.-GES. Sept. 9, 1954 [Sept. 15, 1953], No. 26117/54. Class 51 (1). A process for the combustion of solid fuels, in particular those having a high ash content and the recovery of the heat of combustion consists in introducing the fuel in a finelydivided state into a fluidized layer of non- combustible solid particles kept at combustion temperature, removing the ash from the layer according to the measure of its enrichment therewith, withdrawing the heat of the layer not needed for maintaining the combustion temperature with the aid of heat-absorbing members arranged in or around the layer and then utilizing the heat. The non-combustible particles are preferably ash particles originating from the fuel itself and are kept in the fluidized state by combustion air introduced from below but in the use of fuels of poor ash yield or very finely-powered the height of the layer is maintained by the introduction of small-particled, non-combustible solid material such as chamotte grains, roasted pyrites, &c. Substances which contain iron oxide are preferred. The heat may be withdrawn from the layer through tubes containing heat carriers such as boiling water under pressure up to 150 atmosphere, metal or salt melts, or water under pressure or at such flow speeds that the boiling temperature is not reached. Vaporizable liquids such as mercury may also be used: Gaseous heat carriers at e.g. 4 to 20 atmospheres, may also be used, the gas being subsequently used in a gas turbine. After use in the turbine the carrier may be used to preheat the fluidized layer combustion air and/or for drying moist carbonaceous materials to be injected into the layer. The combustion gases leaving the layer may also be used to dry moist materials and this drying may take place in a chamber utilizing the fluidized technique, the moist material forming the solid particles in suspension. In cases where ash-rich coals are burnt the heat of the ash and flue dust leaving the layer may be recovered and used for heating combustion air. The grain size in which the fuel is introduced should preferably be less than 10 mm. and the height of the layer in the quiescent state between 200 and 1000 mm.
