Class 40(5) A calling system comprises a closed circuit 5 running through one or more buildings, e.g. a hospital, supplied with high frequency energy from a transmitter 4 which may be modulated by one of several low frequencies generated by a multivibrator or other modulator 2 selected by a switch 3 or keyboard, and so that persons carrying portable receivers each responsive to the HF energy and comprising an electromagnetic vibrator mechanically resonant to one of the call tones may be selectively called. The receivers may have vertically arranged ferrite or iron rod aerials and single grounded emitter amplifying and detecting transistors with parallel resonant collector circuits forming the energizing winding of a vibrator 12-15 having apermanent magnet 12 and mechanically tuned resilient blade 13. The latter may carry a spring blade 14 striking against a sound board 15 or the blade 13 may close contacts operating a buzzer or loudspeaker. The high frequencies may extend from 20 Kc/c 50 Kc/s and low frequencies from 50-300 c/s with relative frequency difference of 2¢ per cent. Further call channels may then b eproduced by using the same low frequency range and a different high frequency. Further, an oscillator 1 of frequency about 1 c/s comprising a valve whose resistance forms part of the multivibrator 2 may wobble the frequency of the latter, e.g., from 49 to 51 c/s, to allow for temperature or other variations in the receiver vibrator frequency, and the frequency sweep may extend beyond the response of each vibrator to produce an intermittent calling tone. The transmitter may be of Class C type. The receivers may by carried by clips to pockets and may be permanently energized without excessive battery consumption.

Title: Improved machine for the manufacture of lathing
IPC: B28B23/00
Filed: 1920-06-02
Abstract: 168,644. Cooper, S. June 2, 1920. Lathing.-In lathing of the kind formed of slats of wood stuck to a backing of cardboard, webbing, &c., the slats 11 are formed with bevelled side edges, and the narrower faces are in contact with the backing 10 so that dove - tail grooves are formed to key the added plaster into position. A machine for making the lathing comprises two portions, one of which causes the feeding of the web or backing against adhesive - applying roller and the other comprises means for feeding the slats and pressing them on to the web. The web 10 is caused to pass over rollers 14, 15, 16, 17 against a positively rotated adhesive-applying roller 18 and then between adjustable pinch-rolls 19, 20 which control the amount of adhesive, the lower roll 19 being positively driven. The web then passes between the co-operating press rolls 21, 22 which operate to apply the slats to the web. The roll 16 is driven from the main driving-shaft 23, and this roll drives the rolls 15 and 19 through gearing, the adhesive applying roll being driven intermediately between the rolls 16 and 19. The pressure roll 22 is resiliently mounted in the machine framing and is provided with removable sets of projections 56, Fig. 3, on which the wooden slats are pressed by a roller 58 as they are fed from a belt conveyor 41, and carried round until they are pressed on to the web, a weighted retaining-belt 67, Fig. 2, aiding to keep them on the drum. A resiliently mounted stripping-device or devices 42 enter grooves 77 in the roll at the position where the web leaves the pressing-rolls. The slats are moved across the bridge piece 55 disposed between the conveyer and the pressure roll 22 by fingers 44 carried in radial slots in discs 48 disposed at the end of a shaft 79 which is rotated by gearing from the lower conveyer spindle 82. Rollers 53 on these fingers coact with fixed cams 50, 51, 52 to project and retract the fingers, the cam 51 being resiliently mounted so that undue pressure on the fingers in this position will not cause damage to them. The spacing of the slats from the conveyer to the pressure roller may be varied by adjusting the position of the shaft 79 carrying the finger discs relatively to the fixed cams; for this purpose the shaft 79 is mounted in screw adjusted bearings 80 in links 90 pivoted at 91 to the shaft of the upper pressure roller, a link 78 maintaining the meshing of the driving gears 86, 87 for any adjusted position. Saws 78 are provided to trim the edges of the product as it leaves the machine.

Title: Atomic resonance apparatus
IPC: H01S1/06
Filed: 1965-04-09
Abstract: 1,071,006. Masers. VARIAN ASSOCIATES. April 9, 1965 [May 11, 1964], No. 15257/65. Heading H1C. In a beam maser the resonant cavity is surrounded by a magnetically permeable structure to shield the. cavity from extraneous magnetic fields and an electrical coil is wound on the inside of the shield to provide a polarizing field for aligning resonant atomic particles in the cavity. In the apparatus of Fig. 1, a beam of hydrogen atoms from 1 are passed through a state-selecting magnet 4 into a quartz bounce box 3 situated in cavity resonator 2. The atoms in their upper hyperfine state undergo transitions to their lower state in the box 3 and a microwave output signal is taken from the cavity 2 by coupling loop 15 and coaxial line 16. In order to reduce second order field shifts of the hyperfine transition a polarizing field is applied to the atoms in box 3 by means of a solenoid 25, Fig. 2 (not shown), wound on an aluminium coil form inside magnetic shield 21. The end turns of the solenoid are disposed immediately adjacent the end closing magnetic cover 21<SP>1</SP> and 21<SP>11</SP> of the magnetic shield 21 in order to minimize inhomogeneities of the magnetic field of the solenoid due to its finite length, the magnetic covers appearing as magnetic mirrors. By splitting the solenoid into a central section and a pair of end sections. Fig. 3 (not shown), compensation and correction for small residual end effects of the solenoid and for field perturbations due to apertures 24 is effected. The cavity 2 is held at a constant temperature by means of ovens 31, 32. In the arrangement of Fig. 4 (not shown), a beam of calcium atoms are passed through a state selecting magnet (56) into cavity resonator (45) tuned for resonance at the resonance frequency of the atoms and excited at this frequency by energy from microwave generator (48). Resonance of the atoms is detected by a further magnet (52) and beam detector (53). A servo control mechanism, not shown, is employed to control the frequency of the microwave generator to keep the atomic particles on resonance. As in the arrangement of Fig. 1, a polarizing magnetic field is provided by a magnetically shielded solenoid 25 which is substantially wound up to the end closing walls, Fig. 5 (not shown). Thallium or rubidium may be employed as the active medium.
