Title: An improved rotary stabilizer for sound film apparatus
IPC: G11B15/50
Filed: 1935-02-11
Abstract: 446,548. Flywheels. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Feb. 11, 1935, No. 4350. Convention date, Feb. 9, 1934. [Class 122 (i)] [See also Groups XXXVIII and XXXV] A rotary stabilizer for sound-film apparatus comprises a casing containing a rotating element and a viscous fluid which couples the casing to the rotating element, the casing having a cover member fitted into an annular recess in the body member of the casing and held firmly therein by the edges of the one member being spun or otherwise turned over the edges of the other. By this means, the use of fixing screws and heavy packing, which materially increase the mass of the container, is avoided. In the construction shown, the casing 1 which is preferably a magnesium or magnesium alloy casting, is adapted to be fixed to a shaft carrying a drum driven by a sound-film. The cover 7 is secured by turning over the edges 8, 9 of the hub and outer wall of the casing. Within the casing, which contains oil or the like, is provided a mass 4, freely rotatable on ball bearings 3. Specification 415,184 is referred to. The Specification, as open to inspection under Sect. 91, states also that the invention is applicable to practically any apparatus where prevention of irregularities in rotary motion is desirable, such as, for example, synchronous motors. This subject-matter does not appear in the Specification as accepted.

Title: Handle attaching machines
IPC: B31B50/86
Filed: 1973-01-29
Abstract: 1401914 Applying handles to cartons W E HIDDING 29 Jan 1973 [1 Feb 1972] 4364/73 Heading A4G A machine Fig. 2 for applying handles 19 to cartons 18 having apertured handle-receiving portions comprises a conveying path means 20 through the machine along which a plurality of cartons is to be transported, handle-stacking means 27 having support and guide means for holding strips of similarly oriented handles, handle-feeding means to advance a strip of handles one handle at a time, and handle-applying means having handleholding and applying arms 152, 153, Fig. 23 to receive a single handle from the handle-feeding means, automatically to sever the handle from its associated strip and apply the handle to a carton. As described the machine also includes punching means for forming the handle receiving aperture in each carton. In operation a gable-top carton 18, Fig. 2, is fed by a conveyer 20 against a first stop 34, Fig. 3 where an aperture is formed in its ridge by punching means 43. The carton is then pushed laterally away from the stop by a bar 49 and is carried by the conveyer 20 and guided by rollers 54, 56, to abut a second stop 58 at the handle-applying station. After a handle has been applied the carton is again moved by the bar 49 and fed out of the machine by the conveyer 20. The aperture punching means, Fig. 7, comprises a pivoted hollow arm 44 containing a slidable rod 82 with a punch 83 at one end. Lowering of the arm 44 over the carton ridge 18a and advance of the rod 82 and punch 83 are effected by linkages from a driven cam-shaft 48. Removed material is withdrawn by a vacuum pipe 89. The handle feeding means includes the stacking means 27, Fig. 2, in which a stack of handle strips are stored. The strips are supported on a pair of gates 146, 147, Fig. 19, and are lowered one at a time on to a second pair of gates 143, 144, and then on to a saddle 108. A push rod 118, Fig. 11, then advances the strip of handles over the saddle 108 one handle step at a time so that a handle is positioned between the handle applying arms 152, 153, Fig. 23. The handle applying means, Figs. 23 and 26, comprises a pair of pivoted arms 152, 153 between which a handle is fed. The arms are pivoted towards each other to sever the handle from the strip and to force a stem 185 at one end of the handle through the aperture in the carton ridge and through an aperture 186 in the other end of the handle. A hammer 194 is then operated to cause a rod to press against the stem 185 to deform it by cold flow and so secure the handle to the carton. All the operations of the machine are controlled by linkwork from the cam-shaft 48 driven electrically sensing switches control the start and stop of the cam-shaft drive and also operate an alarm if the number of strips in the stack 27 falls below a predetermined number.

Title: Improvements in or relating to electric circuits employing transistors
Inventor: GROSS MICHAEL HUBERT
IPC: H03K3/2893
Filed: 1962-09-10
Abstract: 1,063,052. Transistor comparators. GENERAL ELECTRIC CO. Ltd. Dec. 10, 1963 [Sept. 10, 1962], No. 34599/62. Heading H3T. A monitoring circuit which responds when the difference between two voltages departs from its normal value comprises two transistors to the bases of which the two voltages are respectively applied, a common emitter resistor and a Zener diode coupling the collector of one transistor to the base of the other, the arrangement being such that the voltage departure causes one transistor to be cut-off and to remain so even if the voltage difference returns to its normal value. In Fig. 1 terminal 11 is normally at earth potential and the voltage applied to terminal 9 is such that transistor 2 and Zener diode 10 are normally non-conducting. If terminal 9 becomes more positive transistor 2 becomes conducting and transistor 1 starts to conduct. This renders Zener diode 10 conducting so that transistor 2 becomes more conducting and 1 cuts off. If the voltage at 9 returns to its normal value the circuit will not restore. The Zener diode may be connected in series until an ordinary diode biased such that the Zener diode is always conducting and ordinary diode becomes conductive when the voltage at 9 exceeds a given value (Fig. 2, not shown). A similar coupling may be connected between the collector of transistor 2 and the base of transistor 1 in which case both transistors are normally conductive (Fig. 3, not shown) and the circuit detects a departure in either direction.

Abstract: 559,517. Feeding devices. SACEK, J. April 7, 1943, No. 4608/42. [Class 177] [Also in Groups XXX, XVIII and XXII] Powder (e.g. metal particles for forming tinsel by being passed between rollers 19, 20) is delivered to the rollers through a stationary shoot 18 by mechanism comprising a continuously rotating horizontal drum 1 into which the powder is introduced. through a hollow axle. The drum 1 is furnished with a circumferential trap 4a communicating with the interior of the drum by an opening 5 and which is provided with a rearward extending pocket 7 into which powder falls as the trap ascends. On the downward phase of the rotation of the trap 4a the powder gravitates from the pocket 7 and is discharged at the open end 8 of the trap, in amounts which are equal and independent of the level of the powder within the drum. The trap may discharge into a second similar trap 4b extending in the opposite direction and furnished with a pocket 9, the powder thus being delivered on the rising phase of this second trap. The discharged powder may fall on a vibrating sieve before reaching the shoot 18, and this sieve may take the form of a perforated sleeve 15 surrounding and rotating with the drum 1, and performing also a limited axial reciprocating movement. The perforations 12 are coarse, and register with holes 14 in a surrounding removable cylinder 13, the holes 14 being graduated in size so that delivery to the drums is rendered more continuous. Large particles which cannot drop through the holes 4 are guided by a ledge 21 and inclined shoots to laterally disposed receptacles 23.

Title: An improved process for making structures from animal tissue protein fibres, such as from animal skins, glue leather waste, flesh fibres or the like
IPC: C08L89/00
Filed: 1936-02-19
Abstract: A process for preparing structures, e.g. sheets, films, filaments or similar articles from fibrous animal tissue protein material, e.g. animal skins, glue leather waste or flesh fibres consists in degrading the protein material with the aid of acidic or basic solutions, homogenizing the mixture by intensive mechanical working thereof, shaping the product and simultaneously precipitating and fixing the shaped product by treatment with a liquid bath containing an alkaline or acid precipitating agent and a tanning or hardening agent.  If an acid is used to degrade the protein material, an alkaline coagulant is used and vice versa Suitable degrading or coagulating substances are for example sulphuric acid, hydrochloric acid, acid ammonium sulphate, oxalic acid, pepsin, sodium hydroxide or lime.  Suitable tanning or hardening agents are common salt, formaldehyde, sodium acetate, benzoates, sulphonates, chromates, or hexamethylenetetramine in a basic precipitating bath.  The latter bath gives a very intensive tanning action and hardening may be completed in two minutes.  Shaping of the products is effected by nozzles, pouring funnels, pouring drums or similar appliances. From the precipitating and fixing bath, the product may be led to further baths for neutralization of the acid or base for demolishing the excess tanning agent, for bleaching, washing, dyeing or softening, and finally it is dried.  Clear or opaque products, colourless or coloured may be obtained and suitable weighting substances may be incorporated.  If desired further degraded natural or artificial substances, e.g. a casein degradation mass may be added to the protein mass, a substance being obtained having high elasticity and toughness and low brittleness.  Viscose or some other cellulose derivative may be added to the protein mass.  In an example 100 kilograms of glue leather waste (about 30--40 per cent dry substance) are treated with 6 per cent caustic soda lye until the dry content of the mass is reduced to 4,5 per cent.  The mass is homogenized by intensive mechanical working in a mixer and is led into a precipitating bath through a nozzle or pouring funnel.  The bath contains 5 per cent sulphuric acid and 1 per cent formaldehyde. After suitable further treatment the product is dried.  In a further example a 6 per cent acid ammonium sulphate bath is prepared instead of caustic soda and the precipitation bath consists of 8 per cent soda and 1 per cent hexamethylenetetramine.  Specifications 422,990, 423,017, [both in Group IX], 429,039, and 429,040 are referred to.

Abstract: 633,305. Making electric cables. WESTERN ELECTRIC CO., Inc. Feb. 20, 1948, No. 5094. Convention date, March 31, 1942. [Classes 83 (ii) and 83 (iv)] [Also in Groups XXVIII and XXXVI] Drawing; forging; armouring.-The tubular outer conductor of a coaxial air-space electric cable is made from a tape 26, the outer edges of which have tabs 128 formed thereon to maintain the edges in alignment after the tube is formed. The tape 26 is first passed through a forming unit which consists of a ram 114 mounted in stationary guides and which is slidable with respect to a base 118 which carries a forming die 119. A co-operating die 124 is supported from a plate 130 mounted on the lower end of the ram 114. Movement of the ram downwardly moves the die 124 into engagement with the tape 26. Fins 125 of the die 124 engage portions of the edges of the tape and force these portions into recesses 122 of die 119, thus squeezing them to form the tabs. Predetermined lengths of tape are fed into the.forming unit intermittently, the intermittent movement of the tape being subsequently translated to a constant movement by passing it around a weighted roller which is free to oscillate. The tape is then passed through rollers to form it into a tube around the insulated central conductor, and is finally passed through a serving head where it is bound with helical lappings of metallic tapes.
