Title: Improvements in electric clocks
IPC: G04C13/04
Filed: 1935-09-25
Abstract: 461,703. Electric clocks. JONES, F. HOPE-. Sept. 25, 1935, No. 26506. [Class 139] An electric master clock in which a gravity arm or switch lever G (to close a circuit to impulse dials) is periodically lowered into contact with the armature A of an electromagnet M which thereupon resets the arm G, has a synchronous motor for releasing the arm G. A pendulum is thereby dispensed with. The motor, through wheel B, rotates a wheel C and cam C<2> fixed thereto one revolution in two seconds. A pin C<3> on cam C<2>, once each revolution rotates a fifteen - toothed wheel D through one tooth, so that once each half minute an arm F rigid with wheel D removes the catch K<1> from a pin K on the bell-crank G. The roller R on the latter meets the highest part of cam C<2> and is rapidly lowered by the cam until parts G and A contact to close the circuit to the impulse dials. In a modification, Fig. 2 (not shown), the roller R is carried on an arm rigid with the wheel C, the cam C<2> being omitted, and the arm G when released, falls on to the roller. The wheel C has two pins C<3> and the wheel D has 60 teeth ; the arm F also rotates over a ring graduated to read seconds. In another modification, Fig. 3 (not shown), a self-starting synchronous motor is used and the parts are rearranged. In a third modification, Fig. 4, the roller R is on the arm C<4> of wheel C, as in the first modification, and the arm G is pivoted at G<1> and adjustably counterweighted at G<2>. A lever H pivoted at H<1>, has three positions R, N, A and has an offset H<2> to which is pivoted at P<1> a bell-crank P. If the lever H is at N (Normal) the catch K<1> is released every half minute by arm F. If the arm H is at R (Retard) the top H<3> of the lever holds arm G up permanently so that G and A can not contact and impulses are not sent to the impulse dials. If lever H is at A (Advance) the horizontal limb of bell-crank P is in the path of pin C<3> and the top end of bellcrank P is to the left of catch K<1>. Thus, every two seconds pin C<3> rocks the bell-crank clockwise to release arm G and send an impulse to the impulse dials. Indicating supply failure; alternative supply.- In the construction shown in Fig. 1, when the battery which supplies magnet M and the impulse dials becomes too weak to throw up arm G, the roller R is raised again by cam C<2> and with this help the magnet M relatches arm G on catch K<1>. Impending failure of the battery is plainly visible in the master and in all dials by the increase in the duration of impulse. When the battery becomes weaker still, roller R remains on cam C<2> and the roller meets a hook-shaped part C<5> of cam C<2> and stops the motor. In this position, cam C<2> and roller R hold lever G out of contact with armature A. A relay may be provided in the circuit of the synchronous motor so that when the A.C. supply fails the armature of the relay, in moving, switches on an alternative supply or another means of time measurement. Specifications 1587 /95, 6066/05, and 1945/07, [all in Class 139], are referred to.

Title: Apparatus for subjecting articles to high pressure
IPC: B01J3/06
Filed: 1961-07-21
Abstract: 906,962. Forging-machines. BAROGENICS Inc. July 21, 1961 [July 27, 1960], No. 26551/61. Class 83 (4). [Also in Group XXIX] An hydraulic press for subjecting a body 47 to high pressure comprises a number of pressuremultiplying anvils 70a, 70b, 70c, Figs. 1 and 2, disposed so that they border a central cavity adapted to contain the body 47 comprising a pressure-transmitting medium 46 enclosing a specimen of material 45 to be compressed, the anvils being separated by gaps 78 permitting a drive system to move the anvils towards the cavity which has a shape bounded by a surface defined by movement of a straight line parallel to a principal axis of the cavity in a closed path, the surface being elongated in the dimension of the axis so that the cavity is longer in that dimension than the greatest cross-sectional dimension of the cavity, and a hinged frame 51a 51b, 51c enclosing the drive system and the anvils. The members 51a, 51b, 51c of the frame may be hinged together by pins 59ab, 59bc, 59ac as described in Specification 891,311, and each member houses an anvil 70a, 70b, 70c which is urged by one or a plurality of pistons 62a, 62b, 62c towards the cavity. The front faces of the anvils have inserts 76a which are of high compression strength and engage the outer surfaces of the body 47, the inserts being slightly less in width than the outer surfaces of the body to provide the gaps 78 between the anvils. The body 47 consists of a mass of material 45 to be compressed in an outer casing 47 of pressuretransmitting medium 46 such as pyrophyllite or R g  Cl which, when the anvils are urged towards the centre of the cavity, is extruded to seal the gaps 78, the remainder of the medium being semi-plastic or viscous to transmit the pressure to the material 45. Plates 80, which may be provided with piston-and-cylinder devices to apply pressure to the ends of the body 47 when the length of the body is less than three times the maximum cross-sectional dimension of the body, are secured by nuts 82 to the ends of the hinge pins. The anvils may be shaped to act on a circular or polygonal body. An electric current may be used to heat the body during the pressing operation. In an alternative embodiment, the frame consists of two members 103, 104, Fig. 7, the member 104 having a cylinder 107 receiving a piston 108 having a portion 110 shaped with inclined surfaces 112a<SP>1</SP>, 112a<SP>11</SP>, engaing anvils 70a<SP>1</SP>, 70a<SP>11</SP> of two identical systems 100<SP>1</SP>, 100<SP>11</SP> for applying pressure to two bodies 47<SP>1</SP>, 47<SP>11</SP>. The sliding surfaces between the anvils, frame members and portion 110 may be lubricated by thin sheets of polytetrafluorethylene. The piston and cylinder 107, 108 may be replaced by a plurality of piston and cylinders acting on a common member having the inclined surfaces 112a<SP>1</SP>, 112a<SP>11</SP>.

Title: Improvements in switch drums for starting and controlling electromotors
IPC: H01H3/50
Filed: 1922-10-02
Abstract: 186,916. Krupp Akt.-Ges., F. Oct. 4, 1921, [Convention date]. Controllers with auxiliary switches; controllers, locking.- Drum controllers are locked against undulv rapid return movement and are provided with separate electromagnetic cut-outs controlled by lost-motion contacts between the controller handle and the drum. Movement of the handle K<@> in the direction of the arrow from the zero position shown, corresponding to switching on the motor for driving, takes up lost motion between a bridging contact k<11> and one pair of drum contacts k<13>, k<14>, but owing to the position of a segment k<17> relative to a finger contact k<20>, no circuit is completed through the lost motion contacts until the handle is turned. back. The backward movement brings the contact k<11> across another pair of drum contacts k<12>, k<13> which energizes a magnet g<3> to the line and thus breaks the motor circuit at the contacts of an auxiliary cut-out g<2>. In order to prevent the drum controller from springing back a step before the cut-out has had time to operate, a locking pawl p<2> engages teeth of a section k<21>, and is only released by the failure of a magnet F in a series with the cut-out break g<2>. Similar effects take place when the handle is moved from the zero position in the opposite direction for braking, except that owing to the locking sector k<10> being integral with the handle and formed with teeth of smaller pitch than the sector k<21> the safeguards are applied in reversed order. The apparatus may be simplified by omitting one of the two pairs of contacts and pawl and sector locks, so that the remainder are operative either in driving or in braking but not in both. A main overload circuit-breaker is also provided.

Abstract: 427,628. Cigarette-making machines. WIX, A., 338, Goswell Road, and EDWARDS, W. F. M., 1, Kempsford Gardens, Earl's Court, both in London. Sept. 27, 1933, No. 26638. [Class 130] In a continuous-rod machine having means for removing sections of the tobacco filling and replacing the same by filter tips, the section of tobacco to be removed is first separated from the paper strip 1 on which it rests, for example by inserting a blade 5 between them, the section of tobacco being then severed and removed. The paper strip 1, which is shaped to trough form to receive the tobacco 2, is preferably first flattened out as shown in the Figure, and may be held in this position by the action of suction through holes 8<a>, a flat blade 5 carried by a lever 5<c> on a carriage 10 being then inserted laterally. The carriage 10, which is moved laterally by a cam 10<b> and lever 10<d> and a spring 10<g>, is mounted on another carriage 11 which moves longitudinally with the cigarette rod. As the carriage 11 moves forward, the blade 5 is raised by the action of a cam 5b and spring 5<d> so as to grip the section of tobacco against the underside of an arm 10<a> on the carriage 10. Rotary cutters 16 then sever the tobacco section, after which the carriage 10 returns and the tobacco section is stripped off by a member 18. A plunger 17, actuated by a lever 17<a> and cam 17<c>, then ejects a filter tip 24 from a chamber 10<h> into the gap formed in the tobacco rod. The filter tips are pushed laterally from an intermittently rotating drum 20 into the chamber 10<h>. Instead of flattening out the paper strip 1, a curved separating member may be used for insertion between the paper and tobacco, the latter being severed by vertically reciprocating knives.

Abstract: 151,928. Western Electric Co., (Assignees of Hartley, R. V. L.). Sept. 29, 1919, [Convention date]. Addition to 102,503. Wireless telegraphy and telephony.-The valve modulating-apparatus described in the parent Specification is modified by directly connecting the two plates, and by coupling the outgoing circuit to a circuit connected between the valve filaments and the common plate connexion. The apparatus may also be employed as a de-modulator or detector. A circuit 4 is energized jointly by a high-frequency source 2 and by a signal-producing circuit 3. The grids of the pair of similar valves 9, 10 are connected to opposite ends of a coil 8 coupled to the circuit 4. The filaments are connected together and to the mid-point of the coil 8 through a battery 18. The plates 13, 14 are inter-connected by a non-reactive lead 22 which is connected to the filaments through a battery 24 and choke coil 23, thus forming a path for the directcurrent component of the output current. The oscillatory component passes through a circuit comprising a condenser 25 and coil 26 coupled to the outgoing circuit. The arrangement serves, as in the parent patent, to suppress the carrier frequency and to transmit a modulated wave of frequency differing from the carrier frequency by the signal frequency. The two valves may be combined in a single tube with a central filament, two grids on opposite sides of the filament, and a cylindrical or like plate surrounding both grids. Alternatively, two plates connected by a lead within the tube may be used. In order to compensate for want of symmetry in the coil 8 a variable condenser 21 may be connected across one half of the coil, and the whole coil may be shunted by a variable resistance 19, the mid-point of the coil 8 being connected to an adjustable intermediate point of the resistance. When the apparatus is used as a detector, the modulated received oscillations are conveyed to the circuit 3.
