Title: Improvements in protecting apparatus for presses, machinetools and the like
IPC: F16P3/04
Filed: 1927-04-19
Abstract: 288,034. Guinot, E. April 19, 1927. Interconnecting guard with starting gear.-A press or other machine tool guard is interconnected with clutch &c. operating means so as to be allowed to fall by its own weight, at the same time retarding actuation of the clutch &c.. until it has so fallen. Means may also be provided for locking the guard and actuating means in operative position until the slide or other machine part has substantially completed its stroke. The guard 21 is carried by relatively adjustable, arms 19, 18 secured to a pivot pin 14 passing through a casing 1, Figs. 1 and 5, and' carrying, within the casing, a cam like member 15, the movement of the guard being limited by stops such as 29, 30. A manually or treadle operated rod 36 is adjustably connected to a pivoted arm 31 to which is also connected a link- 33 leading to the starting clutch &c., the arm 31 being secured to a pivot 5 also mounted in the casing 1 and carrying therewithin a lever 6 cooperating with the cam 15. A spring 11 normally holds the lever 6 in the position shown in Fig. 1 with an adjustable stop 9 engaging an arm 17 of the cam 15 and supporting the guard 21 in the raised position. When the lever 6 is rotated by traction on the operating rod 36, the cam 15 follows, the guard descending by its own weight. Upon full descent of the guard, the cam 15 reaches the position shown in Fig. 5 so that a tooth 10 on the lever 6 may engage a notch therein' to enable the clutch actuating movement to be completed. Premature return of the actuating means is prevented by a spring pressed bolt 39 which snaps into a notch 42 in the lever 6, being withdrawn therefrom when the tool slide 50 or the like, in its descent, bears upon a stop 49 om an extension 48 of a bell-crank lever 47, 44 engaging a stop 43 on the bolt. An alternative device (Fig. 11, not shown), for preventing premature return comprises a pivoted bar or plate on the frame adapted to engage a stop on the guard arm to hold it down until in the descent of the tool a stop thereon swings the bar aside. In the modification shown in Figs. 8, 9, the lever 6 and cam 15 are connected by a spring 55, and the limiting positions of the guard are determined by adjustable stops 53, 54 against which the cam abuts. Provision is made for a lost motion connection to the clutch members, either by means of a slot 34 in the link 33, Fig. 1, or by passing the link 33<1>, Fig. 8, through a slotted extension of the arm 31. The guard 21 may be counterweighted by an extension 62 of the supporting arms. The casing 1 is provided with lugs 2 for attachment to the machine frame.

Abstract: 597,389. Liquid electrode apparatus. HIRSH, B. W., CARTER, C., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 27, 1941, No. 10913. [Class 41] An electrolytic cell, e.g. for the electrolysis of brine comprises a lower portion having an elongated plane' surface carrying a mercury electrode and an upper portion carrying an assembly of solid electrode material having the lower surface but a short distance above and substantially parallel to the upper surface of the mercury electrode, the solid electrode being arranged to permit the withdrawal of gas from the inter-electrode space and to prevent the longitudinal flow of liquid through the cell except by the inter-electrode space. The two portions are provided with sealing means and with means external of the cell for adjusting the height of the inter-electrode space. In the construction shown in Fig. 1 the anode is formed of a plurality of blocks 5 extending across the width of the cover 4 and conforming closely to the contour thereof and spaced a short distance apart along the cell so as to provide conduits for egress of the chlorine, which communicate with conduits 11 extending up from the cover. There may be one conduit 11 for every space between adjacent anode blocks or there may be one conduit for a plurality of blocks, narrow channels being provided on the inside of the cover or on the upper surface of the blocks so that the chlorine can pass to the nearest conduit 11, but the channels do not provide a path for the brine alternative to the inter-electrode space. The anode blocks depend from carbon rods 6 forming supply-conductors which pass through openings in the cover. The joints of the rods with the cover are sealed by composition 7. The plane surface carrying the mercury electrode 2 is surrounded by a narrow channel la containing mercury and the cover 4 is provided with a rigid skirt 8 depending below the solid electrode assembly 5 and fitting loosely into the channel 1a ; an endless inflated rubber tube 9 is disposed between the inner wall of the channel and the skirt. The rubber tube 9 may be filled with cold water under pressure which may be circulated to cool the tube. Adjustment of the inter-electrode height is effected by screws 12. Mercury and fresh electrolyte are supplied at one end of the cell and amalgam and spent electrolyte withdrawn at the other. In a modification a space is provided between the anodes and the upper part of the cell and is filled with a resilient material such as a cushion of sponge rubber coated with neoprene polythene or other material resistant to chlorinated brine, holes being provided for passage of the anode supports. The supports may be hollow for withdrawal of chlorine, or separate conduits may be provided joined to a common main. The supporting rods are provided with an external thread and locknut in order to effect compression of the cushion. Specifications 597,387 and 597,388 are referred to.

Filed: 1950-05-06
Abstract: The invention comprises 2 : 6-diethoxy- and 2 : 6 - n - butoxy - tetrahydropyran, 1 : 1 : 5 : 5 - tetra-n-butoxypentane and a process for preparing compounds of the general formul  <FORM:0698736/IV (b)/1> and <FORM:0698736/IV (b)/2> wherein R1 represents a hydrogen atom or an alkyl, aryl or alkoxy alkyl group, R2 and R3 represent hydrogen atoms or alkyl or aryl groups and R represents a primary or secondary alkyl group of 1 to 6 carbon atoms, by reacting a compound of the general formula <FORM:0698736/IV (b)/3> wherein R, R1, R2 and R3 have the above significance, with the required primary or secondary alcohol under substantially anhydrous conditions in the presence of an acid condensation catalyst.  If the amount of alcohol used is about one mole. to one mole. of the dihydropyran starting material, the tetrahydropyran product is mainly formed, further quantities of alcohol lead to the formation of the substituted pentanes.  Suitable acid condensation catalysts are hydrochloric, phosphoric and sulphuric acid.  The reaction may be carried at a temperature in the range between 0 and 100 DEG  C., and preferably at a temperature below 60 DEG  C.  Starting materials which may be used in the process are 6 - alkoxy -, 6 - alkoxy - 3 - methyl -, 6 - alkoxy - 4 - methyl -, 6 - alkoxy - 5 - methyl - and 6 - alkoxy - 4 - phenyl - delta2 - dihydropyran.  In the examples the following compounds are prepared: 2,6-diethoxy- and 2,6-di-n - butoxy - tetrahydropyran and 1,1,5,5 - tetraethoxy - and 1,1,5,5 - tetra - n - butoxy - tetrahydropyran are prepared and are each converted to glutardialdehyde bis-2 : 4-dinitrophenylhydrazone. Other compounds mentioned are 2,6 - dimethoxy -, 2,6 - diethoxy - 5 - methoxymethyl - and 2,6 - di - n - butoxy - 3,4 - dimethyl - tetrahydropyran, and 1,1,5,5, - tetramethoxy -, 1,1,5,5, - tetraethoxy - 2 - methoxymethyl -, and 1,1,5,5 - tetra - n - butoxy - 2,3 - dimethyl - pentane.  6 - Alkoxy -, 6 - alkoxy - methyl -, 6 - alkoxy - 4 - methyl - and 6 - alkoxy - 4 - phenyl - delta2 - dihydropyran are obtained by the interaction of acrolein, alpha-methacrolein, crotonaldehyde or cinnomaldehyde respectively with an alkyl vinyl ether.  In an example, 6-ethoxy-delta2-dihydropyran is obtained by heating acrolein and ethyl vinyl ether in the presence of hydroquinone.

Title: Improvements in and relating to earth-boring systems
IPC: E21B7/24
Filed: 1954-04-21
Abstract: 749,177. Reciprocating motors; automatic control systems. DRILLING RESEARCH, Inc. April 21, 1954 [April 22, 1953], No. 11576/54. Classes 35 and 38 (4). [Also in Group XXI] In a transducer consisting of two annular concentrically-disposed, elongated members 19, 22 at least one of the members is of magnetostrictive material, and the cross-sectional areas of the members are related inversely to the maximum flux densities which can be set up in the materials from which they are formed. The energizing winding 18 is disposed in a recess 19c, formed in the member 19, between the two members, which are formed of sectors of bonded-together, insulated laminations of either constant or of radially-increasing thickness. The ends of the members extend beyond the winding 18 and arc welded together. Various circuits are described for supplying a D.C. biasing current or a variable frequency A.C. current to the transducer, which is used to vibrate an earth-boring bit. As the frequency of the vibrations set up in a vibratory column 12 by a transducer incorporated therein becomes the resonant frequency of longitudinal vibration of the column, then the longitudinal movement of any part of the column is in phase with the A.C. current supplied to the transducer, and the power supplied is a maximum. To maintain the column vibrating at resonant frequency a signal from a strain gauge 32 on the column is fed through an amplifier 250 to a phase detector 251, which also receives a signal from a resistance 252 in a supply line 24. Out-of-phase relationship between the two signals results in a signal to a motor control amplifier 254 and the driving of a motor 255 to alter the speed regulator 259 of the prime mover 175 of the A.C. generator 162 to adjust the frequency of the A.C. supply to the transducer to the necessary extent to cause vibration of the column at resonant frequency. Alternately, variation from the maximum of the power supplied to the transducer results in the indicating arm 501 of the wattmeter 500 making or breaking the circuit of a solenoid 516. Operation of the solenoid 516 results in the inclusion or exclusion of a resistance 513 in the armature circuit of a D.C. motor 255 controlling the speed regulator 258 o. the prime mover 175 of the A.C. generator 162f The D.C. current in said armature circuit is reversed at regular intervals by a motor-driven commutator 511, 512 so that the extent and rate of variation of the speed of the prime mover is dependent upon whether or not the resistance 513 is included in the armature circuit.
