Title: Flash bulb assembly apparatus
IPC: F21K5/08
Filed: 1969-01-02
Abstract: 1,246,402. Making flashcubes. ITT INDUSTRIES Inc. 2 Jan., 1969 [4 Jan., 1968], No. 221/69. Heading B3A. [Also in Divisions G2 and H1] In a machine for making flashcubes by a method which includes the step of threading the lead-in wires of a plurality of flashbulbs through respective holes in a common base, apparatus is provided for positioning the wires prior to the threading operation so that they are correctly aligned with the holes. In the preferred embodiment, flashbulbs (12, Fig. 3, not shown) are arranged in groups of four in holders 38 on conveyer carriages (32) with their lead-in wires 20 in approximately the correct position and the carriages are brought in succession to the wirepositioning station where a group of relatively wide fingers 72 and relatively narrow fingers 74 forming part of a unit 68 is slidably inserted between the wires. A second group of relatively narrow fingers 80 forming part of a unit 70 is then moved forward between the fingers 72, 74 so that the lead-in wires are located in a series of narrow inter-digital slots of about the same thickness as the wires themselves. Two further units 84, having fingers 86 which are perpendicular to the fingers 72, 74, 80 and are slidable in transverse grooves 106, 110 therein, are then advanced from either side to confine the wires against lateral movement in any direction. A properly orientated base (14) is then lowered on to each group of bulbs so that the wires enter the respective holes (23), the fingers are withdrawn and the carriage is moved on to the next station where the wires are bent over and secured to an annular rib (24) on the base. The tips of the fingers are tapered to deflect the wires into the correct spaces and the holes (23) have flared mouths (114) to facilitate the insertion of the wires therein. Each bulb (12) is supported in its holder 38 by a conical spring (52) which prevents damage to the bulb when the base is applied.

Abstract: 246,811. Mills Novelty Co., (Assignees of Mills, F. L.). Jan. 29, 1925, [Convention date]. Fraud, preventing.- Relates to a controlledmachine in which an ejector C, Fig. 1, delivers articles from compartments A<2>, and the coincontrolled mechanism controls the operation of a stack of perforated slides D for delivering in known manner checks or coupons from a coupon magazine 5 through a passage 1 leading to a discharge shoot 2 controlled by a slide 2<a>. According to the invention, a slide 14 having a perforation 14<a> is placed between the slides D and the passage 1 and is held against the action of a spring 14<b> with the perforation 14a in register with the passage 1 by a lewer 15 controlled by a delicate spring 15b, Fig. 3. If the machine is jarred or violently tilted in an effort to cause an improper coin to pass the ordinary guard devices, the spring 15b will permit the lever 15 to release the slide 14 which moves rearwardly and obstructs the passage 1. Specification 246,621 is referred to.

Title: Voltage control in electrostatic precipitators
IPC: B03C3/68
Filed: 1971-01-06
Abstract: 1332751 Photo-electric detection systems METALLGESELLSCHAFT A G 6 Jan 1971 [13 Jan 1970] 687/71 Addition to 1071569 Heading G1A [Also in Division H2] A method of controlling the voltage applied between the electrodes 1, 2 of an electrostatic precipitator comprises deriving an optical signal at each flashover between the electrodes by a device 7 having a response time of not more than 10<SP>-3</SP> seconds and using the optical signals to control the applied high voltage to avoid a persistent breakdown between the electrodes. Since the optimum power supplied to the recipitator causes a fixed flashover rate this power may be controlled by measuring the flashover rate using the device 7 which, as shown, comprises a Kerr cell having polarizers 11. The electrode 2 is connected to a high voltage generator 4 and the Kerr cell is connected across the resistor 6 of a voltage divider 5, 6. When a flashover occurs in the precipitator the voltage across the Kerr cell is reduced thereby preventing the light from a source 8 from reaching a photo-detector 10 via a light guide 9. The photodetector is connected through an amplifier 12 to a voltage controller 13 for the generator 4. A variable resistor 5' or 6' may be connected to the Kerr cell which may be replaced by a semiconductor light omitting diode of gallium arsenide or gallium phosphide, the emitted light being infrared radiation.

Title: Improvements in centrifugal pumps, more particularly for domestic use
IPC: F04D5/00
Filed: 1955-01-10
Abstract: 788,549. Centrifugal pumps. RENSON, A. Jan. 10, 1955 [Jan. 12, 1954; Jan. 21, 1954; Feb. 6, 1954], No. 743/55. Class 110 (1). In a centrifugal pump of the kind in which, above the impeller and about the impeller shaft, two separate chambers situated at the same level are arranged each in communication with the impeller compartment, one communicating with the delivery pipe and the other being connected to the inlet by a port formed in the pump body and having no connection with the impeller, the separate chambers are disposed in the bottom of a cylindrical part of the pump body, the cylindrical part being integral with the chambers and with the delivery pipe. In the centrifugal pump shown in Fig. 1 a bladed impeller 21 operates within a chamber formed in a lower casing part 20 and communicating by way of ports 26, 27, Figs. 1 and 2, in a disc 19 with a suction chamber 15 and discharge chamber 16, Figs. 1 and 1A, formed in an upper casing part 1. Water passes fr m the suction pipe 4 to the suction chamber 15 by way of a non-return valve 9 and ports 22 and 18 formed in the casing part 20 and the disc 19 respectively. The discharge chamber 16 communicates directly with a discharge pipe 28 formed integrally with the casing part 1. The drive from the electric or other driving motor is transmitted through a square end 25 of the shaft 24. Any leakage into a space 14<SP>1</SP>, occurring when the pump is not in operation, does not rise above the discharge level, and is sucked away when the pump is restarted. A drain pipe 42, passing through the discharge pipe 28 at 42<SP>1</SP>, may be provided. When the pump is stopped, water remains in the chamber 14<SP>1</SP> up to the level of the pipe 42, facilitating priming. A bore 32 communicating with the chamber 16 prevents air leaking between the shaft 24 and a bearing 23 from reaching the impeller. As a precaution against frost, a nail or other instrument can be inserted through an opening, normally closed by a screw 34, to lift the valve 9 and thereby drain the pump; holes 39 and 41 facilitate draining. The pump can be re-primed by filling the chambers 15, 16 with water through an opening normally closed by a stopper 45. The non-return valve may be at the lower end of the suction pipe. The pump is supported by a member 30 which may be attached to a wall.

Inventor: HIRSH DONALD HENRY
IPC: C07C47/21
Filed: 1962-07-09
Abstract: The invention comprises 2 3-dimethyl-4-pentenal. The compound may be prepared by (i) the vapour phase isomerization of 1-propenyl crotyl ether or (ii) the isomerization of dicrotyl propional.  The 1-propenyl crotyl ether may be obtained by the liquid phase dealcoholation of dicrotyl propional crotyl alcohol being formed as a by-product.  The dicrotyl propional may be obtained by aldol condensation of propionaldehyde and crotyl alcohol.  2 3-Dimethyl-4-pentenal may be converted to 2-methyl-2-(sec.-butyl)-1 3-propanediol by (i) reaction with formaldehyde to give 2 3 - dimethyl - 2 - hydroxymethyl-4-pentenal which is then hydrogenated or (ii) conversion to 2 3-dimethyl-pentaldehyde by (a) partial hydrogenation or (b) complete hydrogenation to 2,3-dimethylpentanol which is then dehydrogenated, the resultant 2,3-dimethylpentaldehyde being reacted with formaldehyde to give 2,3 - dimethyl - 2 - hydroxymethylpentaldehyde which is then hydrogenated. The 2-methyl-2-(sec.-butyl)-1,3-propanediol may be converted to 2-methyl-2-(sec.-butyl) - 1,3 - propane - dicarbamate by (i) reaction with at least 2 mols of phosgene to give 2 - methyl - 2 - (sec. - butyl) - 1,3 - propane - dichloroformate which is then reacted with ammonia, or (ii) simultaneous reaction with phosgene and ammonia.  If an excess of the diol is present during the reaction of 2-methyl-2 - (sec. - butyl) - 1,3 - propanediol with phosgene, the carbonate or dicarbonate may be formed instead of the desired bis-(chloroformate). Examples are given.
