Title: An improved device for disinfecting the mouthpieces of telephones
IPC: H04M1/17
Filed: 1933-05-18
Abstract: 405,458. Spray-producers. KRANTZ, H., 10, Wetherby Terrace, South Kensington, London. May 18, 1933, No. 3119. [Class 69 (iii).] A spray or jet forming means for disinfecting the mouthpiece of a telephone as shown in Figs. 1, 3, 4 and 6 comprises a disinfectant container 2 closed at its upper end by a cap 3 which is perforated for the passage of a rod 4 carrying a piston 5 and surrounded by a spring 7. The rod and spring are housed in a member 8 provided with spaced projecting arms forming a bracket 9 to which is secured the upper end of an arm 11 slotted at 12 to form a guide for a screw 13 projecting from a vertically disposed rod 14. The lower end of this rod is formed with a projection 14a adapted to lie beneath the receiver hook c whilst its upper end is pivoted at 17 to a boss 18 on a lever 16 pivoted at 15 to the outer end of bracket 9, the free end of lever 16 engaging the outer surface of the head 6 of piston rod 4. When the receiver is replaced on the hook c, the piston 5 is depressed against the action of spring 7 to eject disinfectant through the tube 21 projecting through the cap 3 and connected by a flexible tube 21a to an exteriorly grooved tube 21c, Fig. 4, screwed into a nozzle 21b adapted to be secured to the telephone mouthpiece by a clip 22. The tube 21 is surrounded by a larger diameter tube 23 which is connected to the nozzle 21b by a tube 24, an air space being provided between the tubes 21, 21a and tubes 23, 24 so that air is forced out through tubes 23, 24 to atomize liquid issuing from tube 21c., Figs. 14 and 16 show a modification in which the disinfectant is discharged only after a predetermined number of calls. This construction comprises a container 36 in the upper part of a cylinder 35 communicating by a stem 38 with a closed thin metal box-like body 39 carrying a pin 41 passing through the partition 36a. Slidably mounted within the lower portion of cylinder 35 is a tubular member 43 adapted to be depressed step by step against the action of a spring 47 as the pivoted lever 44 is actuated by successive replacements of the receiver on its hook until the member 50 releases the spring 51 when the part 43 is moved sharply upwards by spring 47 and strikes the pin 41 to flex the bottom of the box 39 inwardly and eject disinfectant through the tube 42.

Title: Improvements in and relating to the measurement of the feed or delivery speeds of moving materials
IPC: B21C31/00
Filed: 1943-02-26
Abstract: 563,893. Electric speed - measuring systems. LOEWY ENGINEERING CO., Ltd., and FERNBACH, H. R. Feb. 26, 1943, No. 3141. [Class 40 (i)] [Also in Group XL] The operating speed of a metal extrusion press is measured by means of a member driven by the extruded metal or by the press and interrupting a beam of light at a rate proportional to the speed, the interrupted light acting on a photo-electric cell controlling an electric frequency indicating instrument. As shown, a perforated shutter 7 is driven by bevel gear 5<1>, 5<11> from a friction wheel 4 in contact with the extruded metal M. Light from a lamp 9 is directed by a lens 11 to the perforated shutter 7 and thence through an aperture device 12 to a photo-electric cell 10 connected through an amplifier 14 to a frequency meter 13. The lateral edges of the aperture in the device 12 are movable to permit the width of the aperture to be adjusted to correspond to the width of the perforations in the shutter 7 to produce a sinusoidal pulsation of light. The output of the cell 10 may be heterodyned with a given frequency to vary the frequency range of the apparatus.

Title: Cultivation of human cold virus
Inventor: TYRRELL DAVID ARTHUR JOHN
IPC: A61K39/125
Filed: 1960-01-28
Abstract: A process for the culture of the human common cold virus by incubation in a tissue culture system comprising a culture medium containing cells of human or monkey origin capable of supporting the growth of the strain or strains of virus selected is characterized in that the culture medium is maintained at a temperature of from 30 DEG to 36 DEG  C. and at a pH of between 6.4 and 7.4.  The vessel containing the medium and cells is rolled during incubation.  A preferred pH is 6.4 to 7.2 and especially 6.8 to 7.2, the preferred temperature being 31 to 35 DEG  C. and especially 32 DEG  to 34 DEG C.  The medium may be Hank's saline medium fortified with an enzymatic hydrolysate of lactalbumin.  The medium may contain (a) an alkali metal bicarbonate in a concentration of 0.001 M and 0.01 M or a sodium phosphate buffer having a pH of 7.14 and 7.69 at a concentration of 0.05 M, (b) anti-bacterial and/or antifungal antibiotics, e.g. penicillin, streptomycin and mycostatin.  After incubation for 2 to 14 days, the aqueous liquid is separated from the solids and may be used as a vaccine especially after concentration of the antigens, e.g. by ultra-centrifuging, dialysis or ion-exchange. The invention also relates to a method of testing the potency of a common cold virus preparation which comprises carrying out the culturing process of the invention, observing the cell material under a microscope at a time when a substantial number of primary plaques has been formed but before the formation of secondary plaques, counting the number of primary plaques and comparing the number of primary plaques with the number obtained in corresponding manner with a control preparation of virus.

Patent GB-211151-A (GB)
IPC: H03H7/46
Filed: 1924-02-08
Abstract: 211,151. Plebanski, J. Feb. 8, 1923, [Convention date]. Atmospherics and undesired signals, eleminating; coupling aerial and detector or radiating circuits; diplex signalling; directive signalling; aerials; filter circuits.-The invention rests on the principle that when a number of mutually coupled circuits are simultaneously excited by a single source of oscillations upon which their reaction is neglible, or by radiation, and output is taken from only one of these circuits, the output power depends on frequency according to a law different from that which would obtain if the output circuit were not coupled to the others. According to the invention, the circuits are constituted by two or more coupled aerials, and the coupling may be electromagnetic, electrostatic, or conductive. Thus a number of frame or open aerials may be coupled as shown in Fig. 1 for receiving purposes and excited by incident radiation W, the detector being connected at a, b. For transmitting an aerial 1, Fig. 3, may be coupled with two frame aerials 2, 3, the whole being excited by an oscillator S. In this case the energy distribution in the spectrum radiated is influenced by the coupled circuits. The principle may be employed in diplex working as illustrated in Figs. 7, 8, in which I, II, are transmitting aerials and Ia, IIa, receiving circuits at two stations. The coupling of the auxiliary circuit, n, at the first station is opposite in sign to that, n2, at the second station, and the energy consumed in the 'detectors, D, D2, then depends on frequency in the manner indicated in the upper and lower curves respectively in Fig. 7, in which abscissae represent wave lengths and ordinates represent energy consumption in the detector for a given excitation. The station I transmits on wavelength #1, and receives on wavelength #2, while the opposite is the case for station II. Thus at each station the receiving apparatus has minimum sensibility for the wavelength of the local transmitter and maximum for that of the distant transmitter. The Specification, as open to inspection under Sect. 91 (3) (a). comprises also an application of the same principle to a wave-meter, Fig. 9 (Cancelled). If the coupled circuit n be intermittently opened and closed at t, no sound is heard in the telephone T when the settings of the condensers C1, C2, have certain values from which the frequency of incident radiation W can be determined. The direction of incident radiation can be found by means of the arrangement shown in Fig. 10, in which two frame aerials 1, 2, are coupled together and set at an angle to one another, a detector being applied at a, b. Further, the phase lag between the currents in two coupled coils may be utilized for the production of a rotating field for the purposes of energy transmission or measurement. This subject-matter does not appear in the Specification as accepted.
