Title: Improvements in drilling or similar machine-tool apparatus
IPC: B23Q11/14
Filed: 1945-12-14
Abstract: 605,139. Drilling &c. machines. SPERRY GYROSCOPE CO., Inc. Dec. 14, 1945, No. 33981. Convention date, Dec. 14, 1944. [Class 83 (iii)] [Also in Group XXXV] In a drilling or similar machine-tool, the tool is fed towards the work resiliently, thermally expansive stop means being provided to limit the feed. The drill 35 is driven by a pneumatic motor comprising a jet 38 and a rotor 32 mounted on a shaft 31 carried in a sleeve 23 slidably mounted in a casing 21 under the pressure of a spring 39 to feed the drill. The feeding movement is limited by a wire 26 anchored to the member 23 and to the top of a tube 18. The length of the wire is varied by passing through it a current controlled by a rheostat 42. The jet 38 is supplied by air from a supply 36, and a branch 61 leads to the tube 18 to cool the wire. For optimum working, the rotor 32, which is wide enough to allow for the maximum feed of the drill, emits a characteristic whine which may be used to control the current supplied to the wire 26. For this purpose, a microphone 51 picks up the vibration and is connected to an amplifier and frequency discriminator unit 52, the output terminals of which are connected, through the switch 44, to the leads 45, 46.

Title: Mechanism whereby drawers in automatic slot machines can only be released by means of two coins of the same denomination
IPC: G07F5/04
Filed: 1927-12-17
Abstract: 307,133. Kent, S. G., (Jensen, R.). Dec. 17, 1927. Coin action, mechanical-connection and multiple-coin.-A coin-freed vending machine comprises a delivery slide c<1> having a shoulder b on one wall c into the path of which the end of a gravity actuated bolt a projects. The slide c<1> is released by the insertion of two coins. The first coin, inserted through a shoot h, engages the shorter arm i of a lever x, i pivoted at h<1> in a casing g, and tilts the lever until it is inclined from right to left, the coin dropping through to the money box. The second coin is deflected by the lever to a supporting surface e, where it is retained by a member f, and re-sets the lever in its passage. When the slide is pulled out, an incline e<1> raises the coin in the member f and with it the bolt a which has a projection d engaged by the coin. Specification 259,767 is referred to.

Filed: 1946-11-20
Abstract: 635,990. Spark arresters. TRIGGS, W. W. (Maxim Silencer Co.). Nov. 20, 1946, No. 34447. [Class 25] [Also in Groups XXVII and XXVIII] In a whirl chamber comprising an inlet for introducing gas at one end with a whirling motion, an outlet positioned centrally of the same end, a baffle adjacent the end of the chamber opposite the inlet and outlet is positioned to provide a space between it and the adjacent end of the chamber, the space being connected to the interior by a passage adjacent a lateral wall of the chamber, and one or more vanes located adjacent the baffle and exposed to the gas in the chamber, the vanes terminating within the chamber at a point remote from the outlet. As shown, Fig. 1, an outer-cylindrical casing 11 has located within it a tube 14 thereby forming an annular space 15, the tube 14 being divided into an inlet and whirl chambers 17, 18 respectively, by a partition 16. The outlet 20 has a frusto-conical inner-end 21 upon the outer surface of which are disposed vanes 22. Aligned with the outlet 20 and mounted upon a post 27, which latter is fixed to the partition 16, is a disc 26 and above it a frusto-conical member 29 which surrounds two crossed vanes 30. The whirl chamber 18 is connected by openings 24 and a pipe 23 to a dirt collector 25. In various modifications the frusto-conical member is dispensed with or the disc is replaced either by a cone with the crossed vanes positioned upon its apex or sides or by four blade-like vanes which are secured to the centre of the disc. In further modifications, an annular ring may be positioned on top of the post with two crossed vanes enclosed in a short tube mounted upon the underside of the ring or an inverted frusto-conical member surrounding two crossed vanes is located directly upon the partition. In other modifications, a further partition, which is situated just above the original one, embodies openings or pitched slots and has mounted upon it a shallow cylinder enclosing two crossed vanes. In another modification, the tube is replaced by a hopper 65, Fig. 21, the bottom end of which opens directly into a dirt collector 76, whilst directly below, but co-axial with the outlet 63 and secured by struts 69 to the hopper 65, is a frustoconical component 67 provided internally with two crossed vanes 68.

Abstract: 1440825 A curl dryer U TOMIATI 19 July 1973 [21 July 1972] 34525/73 Heading A4V [Also in Division A5] A curler, Fig. 1 comprises a perforated cylindrical enclosure 1 on which hair is wound and which contains an electric motor 6 to.drive an impeller 7 and create an air current through the hair. Rechargeable electric batteries 4, 5 supply current to the motor via a thermostatic control 8 set to close the circuit at a temperature appropriate to hair drying. The batteries are recharged without removal, by placing the curlers in an electricity supply unit, Fig. 7 which houses a plurality of curlers in compartments 14. Contacts 15 in the compartment engage conductors 9, 11 in the curler which connect with the batteries to complete a charging circuit. Three embodiments of the invention provide for arrangements within the curlers in which the motor is placed either as in Fig. 1 or at the opposite end of the enclosure from a single battery (4), Fig. 3 (not shown) or surrounded by an annular battery (4) Fig. 5 (not shown) from which it is separated by a corrosion shield. For each embodiment corresponding modifications to the contact positions in the supply unit are provided. The electricity supply unit is equipped with a timer and a voltage sensitive relay which prevent overcharging of the batteries.

Title: Method of and apparatus for feeding molten glass
IPC: C03B7/084
Filed: 1929-11-12
Abstract: 337,988. Jackson, L. Mellersh-, (Ball Bros. Co.). Nov. 12, 1929. Delivering molten metal.-Relates to a feeder of the kind in which the flow of molten glass through an aperture. 13 in the floor of a forehearth 12 is regulated by variations in the pressure of the air within a vertical tube 15 that dips into the glass above the aperture. The interior of the tube is connected alternately with a reservoir 30 of compressed air and with a vacuum tank 31 through valves 34, 38, respectively, the valves being actuated by a rotating timer 36. The invention consists in constantly admitting, at a slow rate of flow, an additional supply of compressed air to the interior of the tube 15. This may be done by fitting a tube 50 in the main compressed air line to bye-pass the valve 34, and in fitting in the tube 50 a diaphragm 52 perforated with a small hole. Thus there is a constant leakage of compressed air from the reservoir 30 to the tube 15, but this leakage is not sufficient to prevent the retardation of the flow of glass when the tube 15 is connected to the vacuum tank 31.

The acid or salt may be admixed with clay or other inert powder.  In detailed examples diphenylguanidine malonate, diphenylguanidine hydrogen malonate and diphenylguanidine hydrogen oxalate as such or in the form of their separate constituents are used.  Diphenyl guanidine malonate is a vitreous substance with melting point at 70 DEG  C. and decomposing at 113 DEG  C.  Diphenylguanidine hydrogen malonate is prepared by dissolving diphenylguanidine in an aqueous solution of malonic acid, filtering hot and crystallizing.  The melting point is about 117 DEG C. and decomposition point 130 DEG  C.
