Title: Process for producing a vaccine containing attenuated infectious bovine rhinotracheitis virus and vaccine produced thereby
IPC: A61K39/265
Filed: 1960-01-19
Abstract: A bovine rhinotracheitis vaccine is prepared by attenuating infectious bovine rhinotracheitis virus by passing the virus a plurality of times in a culture of lamb tissue cells particularly lamb renal cells.  At least five, preferably 25, and up to 125 serial passages through the lamb cells are made.  The Ithaca strain of infectious bovine rhinotracheitis virus is used to inoculate a trypsinized lamb embryo renal tissue culture in an aqueous mixture consisting of 80% Earle's salt solution, 10% inactivated calf serum and 10% lactalbumin hydrolysate.  After 72 hours, the virus is transferred to a second culture tube and the process is repeated for the desired number of passages.  The supernatant fluid from a number of culture vessels is pooled, assayed for virus content and diluted with a stabilizing menstruum to give a virus content of 50,000 T.C.I.D. 50's per mil.  The product may be freeze dried. Specification 846,755 is referred to.

Title: Manufacture of hydroxy-trimellitic acid
IPC: C07C51/367
Filed: 1937-01-22
Abstract: Hydroxy-trimellitic acid is prepared by treating pseudocumene-5-sulphonic acid with an oxidizing agent, e.g. potassium permanganate, and subjecting the resulting sulphotrimellitic acid, without isolating it, to fusion with caustic alkali.  An example is given.  The product is useful as a dyestuff intermediate. Pseudocumene - 5 - sulphonic acid is obtained by sulphonation of pseudocumene.

Title: Improvements in oscillation generator arrangements and in frequency modulation arrangements
IPC: H03C3/09
Filed: 1941-02-14
Abstract: 547,183. Generating high-frequency oscillations ; frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and DITCHAM, W. T. Feb. 14, 1941, No. 2050. [Class 40 (v)] Waves of twice the frequency of a stabilized wave source are produced by recombination of sum and difference frequencies obtained from the stable source and a normal source. The arrangement permits frequency modulation of the stabilized double-frequency output wave by applying the signal voltages to modulate the frequency of the normal source. As shown in Fig. 2, waves from a stable oscillator C and a normal oscillator O are combined to produce a sum frequency at 1 and a difference frequency at 2, which are re-combined at 3 to produce an output of twice the frequency of the stable source C. The source O is frequency-modulated by a signal source M, and in one of the paths from the source O to the mixing circuits 1, 2 a filter LO is inserted which suppresses the rapid frequency variations due to the signal but not the slower variations due to drift. In this way the double-frequency output carries the frequency modulation due to the signal, but is free from slow drift variations. The filter LO may be replaced by an oscillator of the same frequency as the source O and loosely locked thereto. In a modification (Fig. 3, not shown), two normal oscillators O of equal frequency are used, one being applied to the mixer 1 and the other to the mixer 2. The first of the oscillators O is frequency modulated, and the other is associated with an inoperative thermionic reactance similar to that used for frequency modulating the first, thus compensating drift due to variations of the parameters of the thermionic reactances. In Fig. 4 two normal oscillators O, O2 of equal frequency are frequency modulated in opposite senses by modulators M1, M2. Waves from the stable source C are combined at 1 with waves from O2 and the sum resultant is fed to the mixer 2 which is also fed with the sum resultant obtained in the mixer 4 from the sources O1, O2. The difference resultant obtained in the mixer 2 is combined at 3 with the output from 1, and the difference resultant at 3 is of twice the frequency of the source C and carries the frequency modulation.

Abstract: 103,874. Avery, W. & T., and Parnell, T. St. J. B. Feb. 17, 1916 Counters with recording-apparatus; detent mechanism; transfer mechanism.-Relates to printing-mechanism for use in combination with automatic weighing-apparatus of the kind described in Specifications 4935/05, 13544/06, and 15690/09, [all in Class 143, Weighing-apparatus], wherein the weight is registered upon a counting-apparatus from which a print is taken, and comprises the combination of numeral printing-disks each constructed so as to form its own pinion and means for preventing excessive movement or accidental reversal of the disks. The numeral disks 1, 2. 3, for units, tens, and hundreds respectively, are each provided with teeth as shown in Figs. 3 and 4 the printing-numerals being situated on the extremities of the teeth. Two lugs 5 on the side of the units disk 1 engage the teeth of a double pinion 6 gearing with the tens disk 2 and thus effect the transfer from the units to the tens disk. Similarly, lugs 7 on the side of the tens disk engage a wide pinion 8 gearing with the hundreds disk 3 and effect the transfer to the hundreds disk. Excessive rotation or accidental reversal of the tens disk 2 is prevented by means of a spring-pressed roller pawl 11, Fig. 3, engaging the pinion 6. To prevent excessive rotation or accidental reversal of the hundreds disk 3, the boss of the tens disk 2 is provided with two slots 16<a>, Fig. 4, so that during a transfer movement of the wheel 8, a toothed wheel 17 moving with the wheel 8 is permitted by the slots 16<a> to move forward one tooth, but owing to the further movement of the slots 16<a> the wheel 17, together with the wheel 8 and hundreds disk 3, remains locked against the boss 16 until the slots 16<a> are again rotated into position for a further transfer. To obtain a printed record, a ticket is placed in a pivoted carrier and is pressed against the type disks by means of a hand-lever the operation of which also causes a projection on the ticket-carrier to enter the teeth of a star-wheel 4, Fig. 3, thus definitely positioning the units disk 1.

Title: Improvements in and relating to electron discharge circuit

Abstract: 575,704. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 10, 1944, No. 2465. [Class 40 (v)] In a high - frequency oscillator in which operating bias is obtained through a grid resistor, the tendency for the oscillations to " block off " due to excess bias is minimized by the use of a negative feedback path for the frequency with which the blocking-off occurs. The oscillator shown in the Figure 'obtains its operating bias from the flow of grid current in resistor 19. Coil 18 has inductance large enough to pass the blocking frequency, but not the oscillator frequency. Coil 21 is so large as to pass neither frequency. Condenser 17 is small enough to pass the oscillator frequency, but not the blocking frequency. Condenser 20 is large enough to pass the blocking frequency. On excess negative bias building up over resistance 19, the consequent reduction in anode current increases the potential of the common point of the coils 18 and 21, which increase applied via condenser 20 to the upper end of resistance 19 reduces the bias, so preventing blocking-off. In a modification, Fig. 2 (not shown), the feedback at the blocking frequency is applied to the grid through a transformer.

The button 1, Fig. 1a, is screwed to the stem 3 and its sleeve 2 is curved as shown to abut the inside wall of the opening in the caseband. The button may be of metal and the caseband of plastic or vice versa. The curved surface of the sleeve may abut a plastic or metal sleeve located in the stem opening. In another example, Fig. ,3a, the plastic crown 7 enters a sleeve 12 in the opening 10 of the caseband 11 and the outer surface of the sleeve is curved at 13 to abut the inner wall 9 of the crown. If the crown is of metal the sleeve is of plastic with an inset metal reinforcing ring. The curved surface may be on the internal surface of the sleeve to cooperate with the external surface of the central tube of the crown. The metal sleeve 21 may be stepped as shown in Fig. 4a to co-operate with a curved surface 19 of the plastic button. If the button is of metal the stepped sleeve is of plastic with an inset reinforcing metallic member. In another example.

In another example, Fig. 6, the plastic button has an internal groove 44 in which is located a split spring 45 which presses the curved surface 41 against the internal wall 42 of the caseband opening.
