IPC: B01J21/08
Filed: 1925-05-28
Abstract: 238,515. Grosse, C. Aug. 18, 1924, [Convention date]. Automatic circuit-breakers. - Electromagnetically released overload cut-outs in the form of screw-down fuses have two members which are brought into contact successively, one of the members being tripped on overload. As shown in Fig. 1, the operating handle, a is arranged to rotate an upper insulating disc c bearing a contact d, the disc c having a pin s working in a semi-circular slot l in a lower disc e bearing a contact d<2>. The disc e is held against a spring f by the notched core g of an electromagnet h pressed upwards by a spring i. When abnormal current flows through the coil h the core i is sucked inwards, releasing the disc e, which is moved by the spring from position 2, Fig. 2, to position 2<a>, so breaking the circuit at contacts d<2>, d'. To re-latch the disc e the upper disc c is moved by the handle from position 1 to position 1<a>, so driving the disc e back to position 2, the handle then being turned back through 80‹ to bring the disc c back to position 1, so completing the circuit at contacts d. d<1>. In a modified form the operating handle a is formed integral with the cover-plate b of the cut-out, the disc e being retained set by a pivoted spring-controlled magnetic detent acted upon by an iron cored solenoid.

Title: Improvements in or relating to copy-milling machines
IPC: B23Q35/18
Filed: 1954-05-13
Abstract: 757,140. Copy-milling. CINCINNATI MILLING MACHINE CO. May 13, 1954 [Feb. 4, 1954], No. 14023/54. Class 83 (3). A tracer-controlled reproducing- machine comprises a variable-angle cutter 48 which is automatically controlled by a mechanism actuated by a tracer 102. The machine, which may be of the type described in Specifications 477,474 and 581,148, has slides 26, 28 movable by handwheels 29, 30, or by a tracer 31 contacting an outline pattern 34. The slide 28 carries a cutter-slide 38 adjustable vertically by hand wheels 73. The cutter, of the type described in Specification 735,416, has two blades 48 adjustable angularly on circular guides by a rod 60 moved by a piston 67 under the control of the tracer 102 contacting a cutterangle pattern 104. The tracer moves a control-valve 91 through a flexible band 94 against the force of a spring 93 to admit fluid-pressure to one side or other of the piston 67. Work 113 may thus be machined with a shaped edge-surface of varying bevel. In a modification, the valve 91, Fig. 9, is connected to a lever 151 pivoted to a piston 140. Pressure is admitted to both sides of the differential-piston 140 by a line 77 and is exhausted by a line 133 and valve 135. The position of the valve 135 is controlled by the pattern 103 and tracer 126 acting through a lever 128. Variations in the pattern 103 thus cause movement of the throttle-valve 135 to vary the position of the piston 140 and thus vary the cutter-angle. The cutter 59 in this case has rack-teeth 125. In a further modification, movement of the valve 91, Fig. 10, is effected by selsyn units 165, 167, the transmitter being actuated by the tracer 117 formed with rack teeth 118. Specification 578,883 also is referred to.

In an electric induction machine, shown in Fig. 2 as a slip coupling, comprising a primary member 1 having salient polepieces 3 each carrying a respective winding 2 fed with either direct or alternating current, and a secondary induced member, the latter is composed of a part or parts 5 consisting of laminated sheetmetal and provided with a squirrel-cage winding 4, and of a part or parts 6 consisting of non- laminated iron without a winding, and all the stated secondary member parts face directly the primary member polepieces 3. This secondary member construction gives a particular torque-slip characteristic which is described in the Specification and is determined by selection of the proportions of the two parts 5 and 6. In other embodiments the two secondary member parts and their inducing primary member polepieces are axially spaced apart, or the non- laminated parts comprise rings disposed one at each end of the laminated part and serving also to retain projecting portions of the squirrel-cage winding against centrifugal force. Applied to a dynamo-electric brake, Fig. 6, the rotary primary member has a double pole wheel having polepieces 23, 25 separated by an annular space in which is disposed the laminated and non- laminated parts 28, 27 of a stationary secondary member 26; alternatively the respective members may be stationary and rotary. The invention is stated to be applicable also to synchronous and asynchronous motors.

Title: Apparatus for Measuring Inclination and Indicating or Recording it at a Distance.
Inventor: BRIGGS HENRY
IPC: E21B47/022
Filed: 1916-10-06
Abstract: 122,201. Briggs, H. Oct. 6, 1916. Bore - hole clino- Meters; levels. - In clinometers, the inclination is determined by the variation of electrical resistance in one or more high-resistance conductors dipping into mercury, the surface of which defines the horizontal plane. The resistances m a y be graphite rods, for example such as are used in lead pencils, or solutions of a salt contained in tubes dipping into the mercury and provided with fixed platinum electrodes. They may be measured directly by an ohmmeter &c., or a Wheatstone's bridge may be used, in some cases with an alternating current and a telephone re ceiver acting as a galvanometer. Or the resistances may be balanced against those of a similar clinometer at an observing station, where the tilt is measured directly. A form of clinometer for use in approximately vertical bore-holes is shown in Fig. 1, the mercury being contained in a glass, vulcanite, &c. chamber d in a casing e. A central iron or steel conductor c is connected to one terminal t<5>, and the resistance rods on tubes a<3>, a<4> to other terminals through bobbins such as b<3>, provided with resistance coils whereby the range of the resistances may be altered. The clinometer may have two resistances in one plane and two in a plane at right-angles, giving the direction of slope in two planes. A clinometer for use in approximately horizontal bore-holes is shown in Fig. 3. The chamber d containing mercury is mounted on trunnions n, m in a casing e and is weighted at the bottom to maintain horizontality. A central conductor c and two resistances a<1>, a<2> dip into the mercury, the resistances being arranged in holes i connected by a passage s. The conductor c is connected through the trunnion n and casing e to earth or to a cable passing to the observing station, and the resistances a<1>, a<2> ta terminals t<1>, t<2> through connexions m, o and u, v respectively. This form determines only the extent of the inclination and not the direction. A similar form may be used for upright bore-holes.
