Filed: 1940-07-01
Abstract: 542,966. Moulding compositions. KREMER, H. July 1, 1940, No. 11113. [Class 70] A dry composite material to be used for moulding articles comprises an inactive filler material, such as wood flour, sawdust, wood chips, cork or fibrous material, or abrasive material, coated or impregnated with a material which, when dry, constitutes a mouldable material and the coated or . impregnated particles are re-coated or re-impregnated with a different kind of material which also after drying is a mouldable material. The coatings may be applied by means of a solution, dispersion or emulsion. The filler may be first coated with a mixture of casein, blood albumen and natural or synthetic (" Neoprene ") rubber containing vulcanizing agents, accelerators and anti-oxidants, a protective colloid such as borated casein glue, and a coagulant such as ammonia alum. The second coating may be a phenol resin. Specification 541,944 is referred to.

Title: Improvements in apparatus for killing poultry
IPC: A22B3/08
Filed: 1923-05-01
Abstract: 211,818. Pacholke, O. C. Feb. 23, 1923, [Convention date]. Poultry, killing.-In a device for killing poultry, the upper part of the beak is placed in a cap 6 secured to the member 2 which is passed into the mouth, the opposing member 1 bearing on the head. A piercing-tool 4 is projected into the head adjacent to the beak and a cutter 5 cuts the artery, and in the form described the tool 4 and cutter 5 operate in succession. The device comprises members 1, 2, the member 1 being hookshaped and U-form in section at 25, and connected by a leaf-spring to the member 2. The tools 4, 5 work respectively through centrally, disposed and laterally displaced slots 22, 7 in the member 2, when the members 1, 2 are brought together by the action of a member 3 pivoted at 10 to an extension 1<b> of the member 1. The hook portion 25 has a central slot 23 and strengthening ribs. The member 2 has a protuberance 17 which engages a lug 11 on the member 3 whereby the members 1, 2, approach one another when the handles 28 are moved against the spring 24. The piercing-tool 4 is pivoted on a pin 9 on the member 3, the pin 9 working in a slot 8 in the cutter 5 which is moved, after delayed action, against the pull of a spring 12. The cap 6, which may be dispensed with, is slotted at 21 and is adjustable by a screw 19. The Specification as open to inspection under Sect. 91 (3) (a) states that the beak is placed in the cap 6 and the head positioned between the members 1, 2, the tool 4 piercing the head and the cutter 5 cutting the throat. This subjectmatter does not appear in the Specification as accepted.
Patent GB-542702-A (GB)
Title: Improvements in or relating to means for converting rotary into reciprocating motion for use in pumps
IPC: F16H21/46
Filed: 1940-07-16
Abstract: 542,702. Reciprocating pumps for liquids. VEAL, E. F., GOLDING, H. A., and WALL, A. J. July 16, 1940, No. 11783. [Class 102(i)] [Also in Group XXIV] In driving mechanism for pumps a crank 14, Fig. 1, is carried by a shaft 15 rotatable about an axis 13. A connecting- rod 16 through universal joints connects the crank with a pump piston 11. The stroke of the piston is varied by displacing the axis 13 through a distance D, Fig. 3, so as to vary the mean inclination 17 of the connecting- rod to the axis 13. In a modification, Fig. 5, the reciprocable member is an arm 19 connected, to the fluid displacer of a vane pump and the crank 14 A is rotated by a pinion 21 gearing with a hypoid gear on the crank. Variation of stroke in this form is obtained by rotating the crank and its shaft 15A bodily about the axis 20 of the pinion 21, the axis being so situated that the upper dead centre position is osly slightly varied. A pump embodying the mechanism first described, is shown in Fig. 8. A casing 30 has a head 33 in which are press fitted four hardened steel pump barrels 32. Inlet ports are provided at 38 and delivery valves at 35, the unions 36 leading to a common delivery. The crank mechanism is carried in a cage 43 having on each side a channel bar 45 running on ball bearings. This cage is connected by rods 57 to eccentrics 50 on a shaft 49 rotatable by a control lever. A hollow driving shaft 60 is splined to a shaft 63 integral with a bevel pinion 65 which gears with a pinion 73 on a sleeve 72 keyed to a crank shaft 66A. Other crank shafts 66B ... 66D are driven through gearing 76 . . . 78. Integral with each crank shaft is a crank 69 having a hemispherical cup 70. Connecting-rods 71 connect these with cups 40 in the lower ends of the pistons above which are springs 41 which serve to maintain ball ends on the rods in engagement with the cups. Movement of the control lever causes the cage 43 to move longitudinally to vary the mean inclination of the rods 71 to the axes of rotation of the crank shafts. The inclination of the crank shaft axes to the pump barrel axes has the effect of producing a mean longitudinal re-action on the cage 43 which tends to maintain it in the position corresponding to zero delivery. The Provisional Specification describes a pump in which the drive is based on the construction described with reference to Fig. 5, and refers to Specification 537,500, [Group XXV].

[Class 18] A device for dispensing tape, e.g., adhesive and/or medicated tape comprises a lid 2 and a base 1 having a sleeve 9 on which a roll of tape is rotatable and a slot 11 contiguous to a slot 12 in the lid through which the tape emerges. A dished plate 15 is hinged to the lower part of the container and has a part 17 adapted when the plate is swung upwardly to engage the top of the container to fasten it. The tape passes over a bead 13 and is severed at an edge 18, the free end of the tape remaining covered by the plate 15. In a modification the plate 15 pivots about a vertical axis.

[Class 97 (i).] Film-winding apparatus comprises two or more concentric discs carrying a film roll, the inner disc being rotated at a speed greater than that sufficient to feed the film at the speed required by the projector, and a retarding device being provided to regulate the film speed. As shown, a disc 13 secured to a boss 14 removably mounted on a boss 7 secured to a spindle 3 is surrounded by a disc 10 loosely mounted on the spindle 3 between the boss 7 and a flange 9. The spindle 3 is driven by the projector mechanism, and directly rotates the disc 13 through a pin 8 connecting the bosses ; the disc 10 is rotated by the friction between it and the flange 9. The discs support a film roll 16 enclosed by a fixed circular casing 11 and by an annular cover 17 attached thereto by bayonet joints. The casing 11 is provided with a spout 12 through which film passes from the projector to the outside of the roll, and the cover 17 is provided with a slit extending from its periphery to its centre opening. The film passes to the projector through the centre opening, round a guide roller 21 serving also to press the film roll on to the disc 13, over a felt or like brake pad 22 serving also as a film cleaner, and over a film guide 28. The spindle 27 of the roller 21 is carried by the cover 17, the brake 22 is carried by a spring 23 adjustable on the spindle 27, and the guide 28 is also carried by the spindle 27. When the film roll is to be removed from the discs, a plate having a core is placed over it, and the core is secured to the boss 14 by bayonet joints.

Abstract: 1389723 Pulse and sawtooth oscillators; pulse modulation circuits INFORMATION STORAGE SYSTEMS Inc 14 March 1972 [12 April 1971] 11864/72 Headings H3T and H4L A capacitive relaxation sawtooth oscillator comprises a pair of transistors for varying independently the frequency and the ratio of rise to fall times. A capacitor C is charged through transistor T 3  until its potential switches a trigger 25 whereupon T 3  is switched off and a diode D 1  is switched on so that the capacitor is discharged through T 2  until its potential restores the trigger and restarts the charging cycle. A pulse voltage is available at the collector of T 4 . Varying the base voltage of T 1  and T 2  by varying V IN  varies the charge and discharge current equally so that the frequency is varied without varying the mark-space ratio of the pulses. Varying the tap 29, by varying the currents differentially, varies the mark-space ratio without varying the frequency. The circuit may be used in a phaselock loop to derive clock signals from binary data.
