Title: Machine for folding a carton blank to form a carton
IPC: B31B100/00
Filed: 1959-07-16
Abstract: 909,886. Making and filling egg cartons. LEHNERSTIRNEMANN, M. July 16, 1959 [June 11, 1959], No. 24426/59. Classes 18 and 94(1). Folding up cartons. The carton shown in Fig 2. is assembled in an inverted manner by feeding a prepared  blank, Fig. 3, on to an apertured plate 34, Fig. 12. A yoke 75 then descends to contact the blank along each of its transverse bridge portions 19, Fig. 3, between partition flaps 18, to press the blank against the plate 34. Further downward movement of the yoke 75 forces the blank and the plate 34 downwardly against spring resistance, Fig. 13, and, at the same time, some fingers 44 (not shown) rise up through the apertures in the table 34 to erect the partition flaps 18, each partition flap being slotted at its mid-point 30. At this stage the sides of the blank are trapped between some members 88 co-operating with recesses in the yoke 75 to cause the blank to crease along the lines 24, 16 and 28, Fig. 3. The yoke 75 is then withdrawn and members 87, 88 are oscillated as shown in Figs. 14 and 15 to complete the carton by causing the side panels 15, 17, 29 to be swung inwardly over the box to close it such that slots 31 in the panel 29 engage the slots 30 in the portions 18. The completed box is then ejected from the machine and inverted to its correct position as shown in Fig. 2. Filling. The cartons are fed from the folding machine 2, Fig. 1, to filling devices 6 (not detailed) by continuously or intermittently operating conveyers 5. The eggs pass from a receptacle 7 to conventional light check means 8 from which they are fed by bands 9 to the fillers. The bands 9, also conventional, align the eggs so that their pointed ends will be directed downwards in the cartons.

Title: Improvements in or relating to radio receivers and high frequency amplifiers
IPC: H03J7/04
Filed: 1937-09-08
Abstract: 486,071. Wireless receiving-apparatus. COLE, Ltd., E. K. (Aga-Baltic Radio Aktiebolag) Sept. 8, 1937, No. 24467. [Class 40 (v)] A superheterodyne receiver with automatic fine tuning comprises an oscillator operating at the true intermediate frequency and means for deriving oscillations of approximately constant amplitude from the intermediate frequency amplifier ; the two oscillations being combined and rectified ; any variation in frequency resulting in a control voltage which is utilized in known manner. The radio-frequency amplifier 10 is followed by the frequency changer 12 and intermediate frequency amplifiers 16, 19, and the local oscillator 13 includes fine adjusting means controlled by potentials over conductor 15. A detector arrangement 23 is fed with voltages of true intermediate frequency from oscillator 24 and voltages of actual intermediate frequency derived from 16 through a limiter amplifier 25. When these two voltages are in phase quadrature it is arranged that the rectified voltage produced by diode 42 across resistance 43 is neutralized by the voltage derived from potentiometer 44, no control potential being applied to conductor 15. A departure from this phase relationship due to the intermediate frequency departing from its correct value results in a positive or negative potential being applied to correct the tuning. Muting of the receiver during tuning is obtained by means of diode 45. Voltages from oscillator 24 and from a point in the output of amplifier 25 which are in phase opposition when tuning is correct, are applied to the diode 45 and with correct dimensioning of condenser 46 no voltage appears across resistance 47 at correct tuning. When tuning is incorrect, however, the beat tones produced are rectified and when the resultant voltage which is passed by filter 48, 49 reaches a certain value, the intermediate frequency amplifier 19 is blocked by this voltage in known manner.

Title: Improvements in or relating to apparatus for measuring torsional vibrations
IPC: G01H1/10
Filed: 1953-09-04
Abstract: 725,523. Measuring torsional vibrations photoelectrically. FORD MOTOR CO., Ltd. Sept. 4, 1953 [Sept. 4, 1952], No. 24476/53. Class 40 (1) [Also in Group XL (b) ]. Torsional vibrations in a rapidly rotating shaft are measured by means of a member secured to the shaft and having a plurality of uniformly spaced light reflecting areas from which light is reflected to a photo-electric cell the output of which is amplified, any frequency variations being converted into amplitude variations which are measured. As shown attached to the end of the shaft under test is a pulley rim in the face of which are cut teeth 10, the outer faces of which are ground and chromium plated while the other source 11 is focused on to the faces, reflected light being received on a photo-cell V7. The voltage developed across the cell is amplified in three stages V2 V3 V4 which ensure that all photocell signals are amplified to the same level by saturating the last valve, the output of the last stage being passed through a 1 microfarad condenser 21 in series with resistors 22, 23 respectively 100,000 and 10,000 ohms. The supply to the grid of a triode V5 is tapped from the junction of the resistors. The triode acts as a low impedance source to match the primary of a transformer T2. The secondary of this transformer is tuned by means of condenser 24 to the repetition frequency of the light pulses, and is working at such a point on its resonance curve that frequency charges are linearly related to the amplitude of the output signal. The output signal is demodulated by a diode V6 and passed to a triode V8 through an 8 microfarad condenser. The signal generated at the anode of this valve is fed through a notching transformer T3 and filters, which reject all frequencies above 1,000 or below 200 cycles per second, to a measuring device which indicates directly the amplitude of the torsional vibration.

IPC: D04B9/10
Filed: 1950-10-09
Abstract: 730,083. Knitting-machines. BENTLEY ENGINEERING CO., Ltd. Oct. 2, 1951 [Oct. 9, 1950], No. 24565/50. Class 74 (2). The upper cylinder tricks of a superposed cylinder machine containing the double-ended needles 75 and sliders 1, also accommodate bits 2 and jacks 5. The jacks 5 have an operating butt 7 and butts 8 at various levels so as to be selectively engaged by selecting cams 9 operated by a pattern drum as described in Specification 730,084. Engagement of a jack 5 by a selecting cam 9 causes it to be lowered so that the butt 7 avoids a depressing cam 14 and is positioned to engage an operating cam 15 whereby the lowering of the jack by this cam correspondingly lowers the associated bit 2 which is further lowered by a cam 20 to cause the slider to engage transfer cams 22, 23. In the event of a jack not being selected by a cam 9, the butt 7 is engaged by the depressing cam 14 which rocks the jack about its fulcrum point 6 so that the butt 7 is out of the range of the operating cam 15. When the butt 7 travels along its camway in the reverse direction it engages a reverse incline 36 on the operating cam 15. The angular attitude of each jack is positively controlled throughout the entire range of its rocking movement by guard ribs 27, 29 which encircle the cylinder.

Abstract: 838,459. Electrode steam boilers. LEDERMANN, H. Aug. 6, 1957 [Aug. 8, 1956], No. 24746/57. Class 39(3) In heating a heat exchanger such as a cooking vessel or water container 8 or a radiator by steam evolved from a boiler 4 in which water is heated by passage of current therethrough between electrodes 5, 6, the boiler 4 is connected by a pipe 3 to water container 1 which is heatedpreferably by a resistor 2, and steam passes from the boiler through a pipe 7 to a jacket of the vessel 8, whence condensate returns through a pipe 9 to the boiler 4, thereby forming a hermetically closed system. When cold, the container 1 is full of water, and the space above the water level in the boiler 4 and in the jacket of the vessel 8 is filled with inert gas. When the electrodes and the heater 2 are energized by the switches 10, 11, steam is formed in the container and drives water into the boiler 4; and the system becomes self-regulating, dependent on the amount of condensate formed by the vessel 8 and the vapour formed in the container 1, the heating of which can be regulated. The heater 2 or a part thereof is regulated by change of voltage through a transformer, by a regulating resistance or by varying the duration of pulses of current, and the regulation may depend on the pressure or temperature of the container. Thermostats in the container 1 and in the boiler 4 switch off heating when a certain temperature is reached and a melting fuse may be placed in the boiler 4 or in the jacket of the vessel 8 to interrupt current supply; and a soft-soldered fuse which blows on excess pressure may be placed in the boiler 4 pipe 7 or jacket of the vessel 8 above water level. The safety devices may operate electro-optical or electro-acoustic alarms. In a modification, the heating jacket of the vessel 8 is replaced by a U tube within the vessel through which the steam passes. The ends of the U tube besides being connected to the pipes 7, 9 is also connected through a soft-soldered metal stopper to a container into which the inert gas flows on development of excess pressure of steam in the boiler 4

Filed: 1937-09-13
Abstract: 502,107. Regulating liquid-levels; rain gauges. NILSSON, O. F. Sept. 13, 1937, No. 24870. [Classes 106 (v) and 123 (i)] [Also in Group XX] A rain-, snow-, or hail-gauge which is required to measure accurately small amounts of precipitation is provided with an overflow arranged to be lowered and elevated according to the liquid level in the receiver to avoid in-. accuracies due to surface tension effects at the overflow edge. In warm weather, the collecting vessel 9 discharges directly to a measuring vessel 11, but in cold weather, the valve 13 is closed and the vessel 9 filled with calcium chloride to liquefy snow or hail. The liquid is maintained at the same level in an auxiliary vessel 15 through a pipe 14, and a flexible overflow 16 is provided, having a mouthpiece 17. The overflow is given a magnified up and down movement by means of a float 18 through a lever 19 pivoted at 20. A very small rise of level in the vessel 15 cause a sufficient lowering of the overflow 17 to overcome surface tension and cause liquid to flow out into the funnel 21 and vessel 11. Precipitation collected in the vessel 9 mixes very slowly with calcium chloride in the bottom of the vessel, so that liquid displaced through vessel 15 to vessel 11 will correspond exactly in weight. The outlet of the overflow 16 is formed as a drop mouthpiece 23 with a pointed lip so formed that a drop falling leaves the tube full of liquid. To provide for an unusually large precipitation, a fixed overflow may be provided above the drop mouthpiece. The movable overflow may also be applied to a measure of liquid capacity. A vessel 40, Fig. 4, discharges through pipe 41 having a valve 42, and is provided with an auxiliary vessel 43 having a float-controlled overflow as described, connected to the main container by a flexible tube 44 which has an internal helical spring to prevent change of volume. The vessel 43 is set at a scale division representing the desired volume, and liquid is poured into the vessel 40 until it overflows at the outlet 49 under the control of the floatactuated overflow mouth-piece. The measured volume may then be drawn off through the tube 41.
