Title: Improvements in and relating to electric selectors for telephone systems
IPC: H01H67/12
Filed: 1938-08-15
Abstract: 506,126. Electric selectors. MERK, F., and TELEFONBAU UND NORMALZEIT GES. Aug. 15, 1938, No. 24041. [Class 40 (iv)] In a selector for telephone installations comprising a switch S having a wiper B engaging contacts K, the switch is moved by stored energy, e.g. gravity, and the speed of the switch is limited by a member driven independently of the switch. Thus a toothed drum TVS, driven by the switch is adapted to be moved into engagement with, so as to be restrained by, a disc VS rotated at a constant speed as by a motor M through gears R and RV, the gear RV being secured to the shaft RVW. The drum TV S is fast with a pinion TV freely mounted on the shaft RVW and engaging a rack ST on the swicch. When the magnet. KM is energized, the pinion TV is displaced along its axis so that the pawls N on the disc VS, are engaged by the teeth of the drum TVS. which cannot then rotate faster than the disc VS. A gear RR driven by the gear RV, raises the switch to its normal position through a dog clutch MR, TRS pinion TR and the rack ST. When the switch, reaches its lowest position, the pin TK1 rocks the lever MH and makes the clutch operative to raise the switch, declutching being effected by the pin TK2. The switch is operated under the control of magnet EM, the armature EK of which permits the switch to fall under the control of the one-way coupling TVS, VS. The magnet KM may have a slow response and be connected in series with the magnet EM so that the speed limiting device is only effective when a long impulse is received.

Title: A method for use in the production of plastics articles for the cultivation of living animal and human cells and tissue
IPC: C12N5/00
Filed: 1964-06-10
Abstract: Plastics articles, to be used in the cultivation of living animal and human cells and tissue, are sterilised by irradiation using, for example, u.v. or X-rays, and subjected to an additional dose of irradiation to obtain a total dose of at least 5 megarad. The additional dose may be continuous with the sterilization process or a separate treatment. The irradiation causes the plastics material, which normally has surface properties which prevent the adhering of high surface tension liquids, such as aqueous solutions, and of living specimens, to undergo property changes such that the above surface properties are reversed. The material also becomes more heat resistant and resistant to chemical attack.  The process involves an increase of cross linking in the plastics material, some oxygen being linked to the double bonds due to the additional irradiation.  The plastics material may be polystyrene, the preferable total dose for which is 8 megarad, and irradiation may be carried out by a cobalt gun.ALSO:After irradiation by U.V. or X-rays to sterilize polystyrene articles, the articles are subjected to an additional dose which causes an increase in cross-linking, some oxygen being linked to the double bonds.  The additional dose causes the polystyrene, which originally had surface properties which prevented the adhering of acqueous solutions or living cells, to undergo a reverse in these properties and also become more resistant to heat and corrosion.
Patent GB-424691-A (GB)
Title: Process and apparatus for the production and application of ozone
IPC: C01B13/11
Filed: 1933-08-31
Abstract: <PICT:0424691/III/1> Apparatus for the production of ozone for therapeutic purposes has a gas inflow pipe, to which may be attached a suitable supply of oxygen or air, provided with a pressure regulating valve and velocity measuring gauge, leading to an ozone producer from which the gas is conveyed to the point of treatment by means of a flexible outflow pipe terminating in a suitable applying instrument, e.g. a canula.  The ozonizer may consist of two spaced coaxial tubes, the outer having a metallic coating connected to earth, and the inner tube having an internal metallic coating connected to a source of high potential or the inner metallic coating may be replaced by a closed glass tube filled with a gas such as argon or chlorine of which the spectrum contains ozone producing and as few as possible ozone decomposing rays.  The dielectric material may also be permeable to ultra-violet rays. The supply of gas may be introduced tangentially into the ozonizing space.  In the construction shown in Fig. 3, the gas circulates at high velocity along the spiral passage immediately surrounding the inner electrode E filled with gas and then passes tangentially into the outer space where it is again subjected to ozonization at low velocity.  The direction of flow of the gas may also be reversed.  The flexible outflow tube consists of a small bore seamless metal tube of ozone-resisting material, e.g. aluminium, arranged in the form of a screw and may be provided with a protective outer coating.  For injection purposes, the flow of gas may be reduced by inserting capillaries or a porous ceramic filter in or before the applying instrument.  Fig. 6 shows a canula with an enlarged mouth for applying ozone to large surfaces of the body.  Fig. 5 shows a flexible hollow needle with a cone which is inserted into the conical mouth of a canula and acts as a further regulating valve.  A needle of this type may be used for the treatment of the root passages of teeth.  The olygo-dynamic action of silver in root passages which have been treated with ozone is increased.  The Specification as open to inspection under Sect. 91 states that the olygo-dynamic action of silver articles or instruments is increased by preliminary treatment with ozone.  It is also preferable to make any articles to be used for insertion, such as drainage tubes, needles, or sheets, of silver to obtain an increased olygodynamic action when ozone treatment is used.  This subject-matter does not appear in the Specification as accepted.

The head of the tube may be large enough to act as a spreader and during transport, a disc of paper &c. may protect the slit in the diaphragm. The closure is adapted to keep cod-liver oil &c. out of contact with the atmosphere to prevent oxidation thereof.

For example, the backwash rate will be four times the normal downflow rate of unit 12 if the filtrate from units 14 and 16 is pumped upwards through unit 12 by pump 106 and an identical booster pump 116. The backwash liquid, with suspended particles, leaves the top of unit 12 through pipe 54, and is discharged through pipe 78. The backwashing is preferably preceded by an air-scour of the unit to be cleaned, the liquid-level therein being pumped down to the level of a lower sensor before pressurized air is supplied to the unit from supply 120. The filtration of water for removal of solid particles is referred to. The filter bed may comprise sand, anthracite, and combinations of sand and anthracite. Ion-exchange resins are also mentioned.

In an IC the components of which are isolated by junctions, parts of one or more of the junctions are enlarged beyond the size required for separation purposes to increase their capacitance which capacitance is utilized to stabilize the supply voltage. Fig. 2 shows a section through part of an integrated circuit comprising a NAND gate (Fig. 1, not shown) in which the isolation junction 11 surrounding a region 12b containing two diffused resistors 5, (6) is reverse biased by the supply potential U B  so that the junction capacitance has a stabilizing effect. The device comprises a lightly doped P-type substrate 20 on which is epitaxially grown a more heavily doped N-type layer 14 which is divided into islands 12a, 12b by even more heavily doped P-type frame regions 15. The majority of the junction capacitance is provided by the area between the N-type region 12b and the P+ type region 15 since the depletion layer is thinnest at this point. The junction capacitance is increased in a first embodiment, Fig. 3 (not shown), by giving the junction a meandering shape to increase its area. In a second embodiment, Figs. 4 and 5 (not shown), P + type columns are diffused through the region 12b at areas not used for the resistors to increase the effective junction area. The columns may be circular, annular or rectangular in cross-section. In a third embodiment, Fig. 6 (not shown), a highly doped N + type layer is diffused into the resistor site before depositing the epitaxial layer to produce a buried layer which extends further laterally than the N-type region containing the resistors to increase the area of the junction contributing to the capacitance. In a modification of this embodiment, Fig. 7 (not shown), a thin N-type surface layer of the same lateral extent as the buried layer is added to further increase the junction area. The integrated circuit also comprises a transistor formed in region 12a, a pair of diodes and a single diode formed in further regions (12c, 12d) respectively.
