Title: Improvements in packing machines
IPC: B65B11/50
Filed: 1939-04-20
Abstract: 527,756. Packeting-machines. NICOLLE, C. A. April 20, 1939, Nos. 11896, 11897 and 11898. Convention dates, April 20, 1939, Jan. 31, 1939, and March 31, 1939. [Class 94 (i)] The machine fills tablets, pills &c. into recesses in cellulosic &c. sheets and encloses them by the application of another sheet, which may be plain or recessed. The tablets are fed from a hopper 14, Fig. 4, adjustably pivoted at 108, on to a band 89 which forwards them to a series of shoots 15. The band is vibrated by a lever 104 to prevent adherence of the tablets, and the shoots 15 are carried on a resiliently mounted arm 71 and vibrated by a device 70. The tablets arrive in a distributer 77 and pass into recesses 9 in a plate'7. The plate is biassed to the left by weight P and is allowed to move a distance corresponding to that between the rows of recesses in the plate 7. This is effected by the action of pawls 31 on racks 32 on the underside of the plate, which allow a step-bystep motion. When all the recesses have been filled, the plate 7 has moved to the left sufficiently to allow an abutment 87 to contact with and operate a device 80 for preventing any more tablets from issuing from the distributer 77. The two plates 7, 8, with the recesses 9 all filled, are pulled manually to the right, and the engagement of abutments 69, 39 causes a diagonal relative displacement of the plates so that the recesses in both register, and the tablets fall into recesses in a cellulosic &c. sheet placed beneath the plates. The cellulose sheet is supported in a lower press plate 224, Fig. 14, recessed to conform to the lower surface of the sheet, and an upper sheet is placed thereon and sealed to it by the bringing together of the plates 224, 225, which are heated by elements 202, 203. A series of press plates are mounted for intermittent rotation about an axis 213, Fig. 12. Filling takes place at position II, the apparatus shown in Fig. 12 being suitably juxtaposed to that shown in Fig. 4 for this purpose. Sealing takes place at III and cooling at IV. The cooling is assisted by the provision of air passages 229, Fig. 14. The completed products are removed, and new sheets inserted at position I.

Title: Improvements in or relating to electrical devices of the kind having a substantiallylogarithmic characteristic
IPC: H03F3/02
Filed: 1951-05-22
Abstract: 703,436. Non-linear valve circuits. GENERAL ELECTRIC CO., Ltd., and DOMVILLE, A. R. May 22, 1952 [May 22, 1951], No. 11943/51. Class 40 (6). [Also in Group XXXVI] A logarithmic electric circuit comprises a resistance in series with plural parallel paths across the input terminals, in each path a resistance in series with a biased rectifier element, and output terminals across the parallel paths; the bias and series resistance values being adjusted so that the output voltage is proportional to the logarithm of the input voltage over a range of input voltages. In Fig. 1 a resistor 1 is connected in series with 6 parallel paths 2 to 7 across input terminals 8, 9, while output terminals 10, 11 are connected across the parallel paths, which comprise resistors 12 to 17 in series with responsive thermionic diodes 18 to 23, biased from potentiometers 25 to 31. The values of the series resistors and the bias voltages are chosen so that the output voltage varies logarithmically with the input voltage over a range of input voltages, the diodes becoming conducting successively with increasing input. The input is coupled through condenser 37, and the D.C. component is restored by diode 36, clamping the voltage across output terminals 10, 11. In a modification, Fig. 2 (not shown), giving logarithmic characteristic over a wide input range, three logarithmic circuits are cascaded with amplifiers interposed between successive pairs. Each logarithmic circuit has a D.C. restoring diode and an amplitude limiting diode, and the outputs of the three circuits are summed across a common output resistor. The output of each logarithmic circuit is limited above the working range, logarithmic within the range, and linear below it, and as the input increases each circuit functions logarithmically in succession over an appropriate portion of the input range, whereby the latter made wider than that of a single logarithmic circuit. Representative resistor and bias values are given.

Title: Safety harness device
IPC: B60R22/34
Filed: 1964-03-20
Abstract: 1,034,001. Safety harnesses. PACIFIC SCIENTIFIC CO. March 20, 1964 [April 1, 1963], No. 11962/64. Heading A3V. A spring reel 6 on which a safety belt 8 is wound is braked at a predetermined speed by means of balls 22 housed in tapered recesses (Figs. 2, 2A, 3, not shown) 20, 20<SP>1</SP> respectively in a collar 9 of the reel and a thrust place 23 which when the thrust plate lags behind the collar are moved into the tapered ends of the recesses, forcing the plate outwardly against the action of a spring 26 to cause gripping means such as teeth 24 carried by the plate to engage complementary means on an end cap 3 of the reel housing. Almost instantly, i.e. after slight further movement of the balls in the recesses, the reel is moved axially against the action of a spring 28 at the other end of the casing to cause teeth 31 on a collar 9<SP>1</SP> to engage teeth 32 on the end cap 3<SP>1</SP>. When the tension on the belt 8 which caused the braking is relaxed the balls re-enter the deeper portions of the recesses and the springs 26, 28 automatically re-centre the reel. The reel may be braked manually by moving a shaft 35 (Fig. 6, not shown) to cause it to force the end of a leaf spring 38 to engage between teeth 40 on the thrust plate and hold it stationary which initiates the braking action described above. In an embodiment comprising two reels (Fig. 5, not shown) each reel has gripping means only at its outer end, both gripping means being actuated whichever reel a belt is withdrawn from above a predetermined speed by means of a bearing stub thrust member 45. The strap may be secured to the reel by being wrapped around a U-shaped insert housed in a slot in the reel.

Title: Procedure and apparatus for wind measurement wherein the  position or velocity vector of a meteorological observation  balloon radio sonde is determined with appropriate time inter vals utilizing a vlf radio navigation system
IPC: G01P13/02
Filed: 1974-03-19
Abstract: 1459934 Radio navigation VAISALA OY 19 March 1974 [5 April 1973] 12054/74 Heading H4D The position of a meteorological radio-sonde balloon is determined using a phase comparison type radio-navigation system, the navigation signals received at the sonde being retransmitted to a ground station by telemetry and the phase information of the navigation signals (here determined using cross-correlation techniques with a locally-generated reference signal). The radio navigation system exemplified is OMEGA and the navigation signals received at the sonde are modulated on to a 400 MHz carrier, together with pressure (P), temperature (T) and humidity (H) signals for reception and detection at the ground station receiver A. The P.T.U. signals are separated out for processing at E whilst the OMEGA signals are received at B1 for passage to cross-correlation processor F1 using a reference signal generator G. To reduce the effects of propagation errors on the OMEGA signals a receiver C receives the OMEGA signals directly from the OMEGA stations a, b, c, for crosscorrelation at F2. The results of the two crosscorrelations are differenced in computer H to remove said effects and further processed to give the required balloon position information. Additional instrumentation comprises: monitor oscillator D, multi-channel recorder I, tape reader J, tape puncher/computer instructor K, console printer L. Details of the correlation process, which is a polarity correlation process, are given, Figs. 2, 3 (not shown).

Abstract: 670,852. Ammunition fuzes. POUDRERIES REUNIES DE BELGIQUE SOC. ANON. May 15, 1950. [March 2, 1950] No. 12067/50. Classes 9 (i) and 9 (ii). Percussion fuze for a land-mine or like explosive device comprises a casing 2 with an annular shoulder 3 resting on ribs 4 in the mine casing. A cover 5 is adapted to be driven into the casing 2 by pressure on a stopper 6 in the cover 7 of the mine. The cover 7 has ribs resting on an elastic ring (not shown), placed on the ribs 4 to prevent the device from functioning until the pressure on the stopper exceeds a predetermined value. Within the fuze casing 2 is a percussion rod 10 with a square-section upper end 11 engaging a cavity in the cover 5. Four projections 12, 13, 14, 15 (not shown) from the cover 5 are adapted to slide in V-shaped grooves 16, 17, 18, 19 (not shown) within the casing 2. The percussion rod is held retracted by three elastic non-metallic members 20, 21, 22 (not shown), each having a rounded end 23 bearing in a groove 24 while the opposite end 25 engaging between bearing surfaces 26, 27 on the percussion rod is concave to embrace a freely mounted ring 10a. The ends 33, 25 are of strong material, such as hardened rubber or polyvinyl chloride. A ring 28, secured by non-metallic screws 29, holds the cover 5 on the casing 2. During transport the device is locked by a safety pin 30 which can be removed by pulling a cord 31. The rod 10 is also held by a stop 32 which comes into alignment with a groove 33 after the projections 12, 13, 14, 15 have travelled along both arms of their respective grooves. The fuze may be rendered instantaneous by omitting the projectiongroove system and using a push-rod 35, Fig. 4, supporting a shoe 36 acting directly on the cover 5 against the thrust of an elastic thread 38. The mine may be provided with a trap 37, Fig. 5, which when tilted causes depression of the cover 5. When sufficient pressure is applied to the mine the cover 5 is depressed, rotating first in one sense then in the opposite sense. The elastic members 20, 21, 22 which are disposed at 120 degrees to each other are compressed longitudinally and given a rocking movement until they pass a dead centre and again expand forcing the rod 10 to strike a primer and so fire the explosive charge of the mine. Specification 670,853 is referred to.

Title: Improvements relating to the concentration of brine and similar solutions used as the circulating medium in refrigerating apparatus
IPC: F25D17/02
Filed: 1921-05-03
Abstract: 182,982. Heenan & Froude, Ltd., and Walker, G. H. May 3, 1921. Refrigerating, compression machines and processes for; circulating brine through chambers.-Brine used as the cooling medium in refrigerating-chambers, on becoming diluted owing to absorption of water from the atmosphere, is concentrated by being heated by the hot gases from the compressor of the refrigerating-plant that is used for cooling the brine and being then exposed to a current of atmospheric air into which the excess of water evaporates. The brine tanks D, Fig. 1, are arranged in cold-storage chambers below pipes (not shown) in which ammonia evaporates, the brine passing over the pipes from troughs (not shown). From the tanks D the brine is pumped through pipes d to a coil of double pipes A, the brine passing through the inver pipe a and hot gases from the compressor through the annular space a<1>, Fig. 1<a>. The warm brine then passes to a chamber C through which a current of air is caused to flow, and is then returned to the tanks D. In a modification, Fig. 2, the brine flows by gravity to a tank C<1> in which is arranged a coil A for the circulation of the hot compressor gases, the warmed brine then being raised to the chamber C for treatment with air as before. In the construction shown in Fig. 3, the separate chamber C is dispensed with, the contact of the brine with the air taking place in the chamber that contains the coil A through which the hot compressor gas passes and over which the brine flows. The air may be dried.
