Title: Improvements relating to friction couplings or clutches
IPC: F16D27/115
Filed: 1956-09-19
Abstract: 798,173. Friction clutches. RYBA, A., REINISCH, J., and VINATZER, E. Sept. 19, 1956 [Sept. 19, 1955], No. 28629/56. Class 80 (2). In a friction clutch which has automatic compensation for wear a magnetic body 11, 12 is freely mounted on a member 1, 2 which has axially extending lugs 3 carrying the main outer clutch plates 4 and a coupling disc 5. An armature 48 is rotatably carried on a sleeve 47 and a disc 51 transmits the magnetic force through the secondary clutch plates 45 slidably mounted on the sleeve 47 and plates 44 slidably mounted on lugs 43 projecting axially from the magnet body. The sleeve 47 has an internal thread 18 and notches 19 which engage ears 21 of a lock ring 20, Fig. 10. Ring 20 coacts with a ring 22, Fig. 5, which has internal and external threads of opposite hands and is formed with locking teeth 25, 26 at each radial face. The teeth 25, 26 are engaged respectively by teeth 28, 29 of lock rings 20, 27 and operate as ratchets in reversed directions, springs 30, 31 engaging lock rings 20, 27 against their respective teeth. A coupling sleeve 33 engaged with ring 22 by means of the thread 34 is provided with key grooves 35 for coupling to the transmission and carries the inner main clutch plates 37 slidably mounted on notches 36 and a disc 38. Sleeve 33 is also provided with notches 33<SP>1</SP> which are engaged by the ears of the lock ring 27. The member 1, 2 is journalled on the sleeve 47 by bearings 42. Energization of the magnet coil attracts the armature 48 and tends to engage the main clutch through the ring 22 and the sleeve 33. If, due to wear &c., the main clutch is not fully engaged the relative movement between the parts 47, 22, 33 causes the latter to move in the direction to fully engage the clutch irrespective of the direction of rotation of the driving member. When the coil is de-energized the coupling is released but remains in the new setting. The secondary clutch 44, 45 may be omitted and the armature 48 fixed directly to the sleeve 47. A mechanically operated coupling has an axially slidable sleeve 52, Fig. 3, with spring-loaded balls 55 engaging in annular grooves 61 and a dished spring 65 to provide the elastic element. Movement of the sleeve 52 couples the secondary clutch 58, 63 and engages the balls 55 in an annular groove 60 to generate the coupling pressure. In a further construction the automatic compensation means is applied to a clutch engaged by spring pressure. Liquid or air may also be utilized to provide the coupling pressure.

Title: Improvements in or relating to the method of making and filling sterile containers formed of fibrous material
Inventor: WILCOX ISAAC LOUNSBURY
IPC: B65B3/02
Filed: 1951-12-07
Abstract: A method of packaging milk in a sterile container of fibrous material comprises heating the flat blank from which the container is to be formed until it is sterile, forming it into an openended container, filling the container and closing its open end. Alternatively, a body blank and two end closure blanks are sterilized by heating, the body blank and one end closure blank are folded and sealed together to form an open-ended container and the other end-closure blank is formed into a cap which is sealed to the container after filling. The blanks may be coated on their inner surfaces with a synthetic thermoplastic material, e.g. the copolymer of vinyl chloride and vinyl acetate, which is impervious to liquids and bacteria and may be subjected to high surface temperatures for short periods without being adversely affected. Specification 669,369, [Group XVII], is referred to.

[Also in Division A2] Double cigarettes are carried in the grooves of drum 14a and after being cut by a rotating wheel 13 (not shown) into two separate cigarettes, each pair of cigarettes is deposited upon the grooves of respective rotating drums 6 after one cigarette of each pair has been reversed through 180 degrees. Thus in Fig. 4 each pair of cigarettes from drum 14a is received in a groove 12 of drum 11a and in holder 15 of the same drum. Holder 15 is given a rotating movement as shown so that the pair of cigarettes is discharged on the drum 6 with the tipped ends facing in the same direction. Rotation of holder 15, Fig. 2.-Holder 15 grips each cigarette by means of suction delivered through holes 16 which are connected by air pipe 18 and ring 19 to the duct 17a formed in stationary shaft 20. Holder 15 is given a rotating movement as the drum 11a rotates, by means of roller 27 which runs in fixed groove 28. The up and down movement of roller 27 is transmitted to holder 15 through crank 26, shaft 25, quadrant 24 and gear 23 so that the holder turns about axis 18. Alternatively the rotation of holder 15 may take place with the opposite rotation so that the resultant position of the cigarettes is in two lines which overlap.

Abstract: 1,211,039. Photographic materials. CESKOSLOVENSK  AKADEMIE VED. June 19, 1968 [June 21, 1967], No.29169/68. Heading G2C [Also in Division C3] Binders for photo-sensitive layers are hydrophilic, water-swellable, water-insoluble polymers of aliphatic monoesters of a polyol and acrylic or methacrylic acid. The binders are used in place of gelatine in silver halide emulsions and may be used in diazo layers. They may be homo-polymers, copolymers (e.g. with vinyl esters or alkyl esters, ethyleneglycol diesters and nitriles of acrylic and methacrylic acid), or graft copolymers (e.g. with gelatine, bone glue, starch, carboxymethyl cellulose, polyvinyl alcohol or copolymers of acrylamide or methacrylamide with acrylic or methacrylic acid or esters). The photo-sensitive layers may be formed by casting a dispersion of photo-sensitive substance in a solution of binder in an aqueous organic solvent and may be sensitized by adding a dye or a sulphur sensitizer (e.g. cystine, cysteine, glutathione, histidine and methione and their HCHO condensates, thiourea, allyl dimethyl thiourea, alkyl thioureas and thiosemicarbozide) or by converting OH groups in the polymer to SH groups (e.g. using P 2  S 5 ). Where a graft copolymer is used the silver halide may be dispersed in the binder before or after grafting.

Abstract: 159,029. Howarth, M., and Rylands Bros., Ltd. Nov. 24, 1919. Right to Patent relinquished. Drawing wire.-In a continuous wire or rod drawing machine having a series of rotary drawing-blocks, the wire is fed off the blocks by the pull of the wire which in passing from one block to another acts on devices which are mounted on and frictionally rotated by the blocks. In the form shown, Fig. 2, rings 13 provided with inclined guides 15 and apertures 14 for the wire are secured by a number of arms 20 to friction discs 19, which are mounted on ball bearings 18 on castings 16 secured to the drawing-blocks 4, 5, Fig. 1. Ball bearings 21 are also provided between the discs 19 and plates 22 secured to the castings. The plates are provided with rings 24 which are pressed against the discs 19 by screws 25 to adjust the friction between them. The wire is passed through the first die 2, and a number of turns drawn on to the block 4. The end of the wire is then passed through the aperture 14, round a pulley 17 carried by a spring-mounted slide 8, thence under a pulley 27 and through the second die to the block 5. After drawing on to this block, the wire is passed in a similar manner to the block 6. In operation, the block 6 is first driven to wind the wire thereon and the block 5 then put into gear, the pressure. on the ring 13 being adjusted so that the wire is fed from this block by the pull of the wire retracting the ring. The block 4 is then similarly put in gear. The speed of the blocks may be so arranged and regulated that no accumulation of wire on the blocks takes place. According to the Provisional Specification, the feeding-off device consists of an arm with a guide eye for the wire loosely mounted on the block spindle and having springs working in frictional contact with the block, or the arms may be driven from the blocks by ratchet or clutch devices. The blocks may also be of the same size and driven at the same speed, the wire accumulating on the first blocks as compared with the second and so on.

Title: Electrical impulse generator
IPC: H01J17/44
Filed: 1952-11-24
Abstract: 717,952. Digital electric calculating-apparatus. NATIONAL CASH REGISTER CO. Nov. 24, 1952 [Dec. 4, 1951], No. 29603/52. Class 106 (1). [Also in Group XL(c)] An electrical impulse generator comprises a plurality of gaseous electronic discharge devices arranged as two different operational groups by having; the cathodes in each group connected together and over an individual impedance and thence over a single common cathode resistor to a source of potential and also to a single output point, chain connections between the devices of the two groups whereby a conducting device in one group initiates conduction in a device of the other group so that discharge devices in the two groups are rendered conducting alternately in a sequential operation, couplings between the two cathode groups so that conduction in a device of one group causes any conductmg device of the other group to be extinguished, and control devices adapted selectively to be operated to interrupt the sequential operations at any point thereby to determine the number of impulses appearing at the output point. In the described embodiment a chain of coldcathode tubes 1 ... 7 have their probe electrodes P each connected to the igniter I, of the next higher tube by a switch S1 ... S7. The cathodes of the odd-numbered tubes are connected together to form one group while the cathodes of the evennumbered tubes are connected to form a second group coupled to the first by a capacitor 66. A positive pulse applied to the grids of a normally biased-off thyratron 70 by closing a start key 98, causes a brief conduction of the latter whereby a positive pulse is passed to the igniter I, of the first tube 1, causing it to conduct. The rise in potential of its probe electrode P is transmitted to the igniter I, of the second tube 2 establishing an ionizing discharge and causing conduction across this tube. The rise in potential at the cathode of tube 2 is transmitted as a positive pulse via the capacitor 66 to the cathodes of the odd-numbered tubes, and serves to extinguish the tube. 1. In this manner the discharging condition travels along the chain of tubes until an opened switch S1 ... S7 is reached, when the desired number of impulses. will have been transmitted via the output tube 85. A number of parallel chains of tubes settable in accordance with the digits of a multidenominational number may be controlled from a single tube 70: The electrode systems of the series of tubes 1 ... 7 may be arranged in a single envelope.

Title: Improvements in or relating to electrical oscillation generators
IPC: H03L5/00
Filed: 1948-11-15
Abstract: 654,758. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd., and MUNNS, J. G. W. Nov. 15, 1948, No. 29645. [Class 38 (iv)] [Also in Group XL (c)] An ultra-high-frequency oscillation generator comprises a first high-frequency generator, the output of which is mixed with a second source of oscillations of substantially lower frequency, the sum or difference frequency being selected and detected to provide an electric signal proportional to the amplitude, which is applied in a feed-back path to vary the amplitude of the second oscillations so as to maintain the amplitude of the sum or difference oscillations constant. The invention is suitable for use with ultra-high-frequency generators in which it is difficult to apply amplitude control directly. In Fig. 1, the output from an oscillator 1 having a frequency of approximately 1000 megacycles, is mixed in frequency-changing device 4 with the output from an oscillator 2 operating at approximately thirty megacycles. The sum or difference frequency is selected and applied to the output point 5 after amplification in amplifier 7. The output is also applied to a detector 6 which supplies a control voltage proportional to the amplitude, which is used to control the amplitude of the oscillations from oscillator 2 either directly or by varying the gain of amplifier 3, so that the amplitude of the oscillations at point 5 is maintained constant. In an alternative arrangement, the lower frequency oscillations before being applied to amplifier 3, are obtained from the difference frequency resulting from mixing the output from oscillator 1 with that from a crystal-controlled oscillator the output of which includes a high order harmonic content, so that the difference frequency is relatively low, and of the same order as that from oscillator 2 in Fig. 1. The control voltage in this case is used to vary the gain of the amplifier 3. An automatic frequency-control arrangement may also be associated with the circuit described.
