Title: Improvements in or relating to fountain pens
IPC: B43K5/00
Filed: 1923-10-30
Abstract: 224,084. Wade, L. R. Oct. 30, 1923. Reservoir pens.-In a reservoir pen of the kind in which an intermediate ink-feeding member D, Figs. 1 and 4, is provided between the barrel A of the pen and the nib-section B, so that, by relative rotation of these parts eccentrically-arranged ink-passages d<2>, b<3>, Figs. 3 and 4, can be brought into or out of alignment, the joint between the parts is made tapered or conical so that there are surfaces above and below the inkpassages in continuous contact in order to prevent leakage. As shown in Figs. 3 and 4, a conical shank on the intermediate member enters a corresponding recess in the nib-section, but the converse arrangement may be adopted. A resilient washer C may be provided between the parts if desired. The member D may be secured in the barrel or formed integral therewith, and the amount of rotation of the nib-section B is determined by the engagement of a lug b<1> on the nibsection with a recess a' in the barrel. A split ring b<2> having extensions covering the lug b<1> may be secured on the nib section. The section B and member D are secured together by a screw which, in order to prevent leakage, does not pass right through the end of the member D. To facilitate the flow of ink, the passages b<3>, d<2> are preferably in the form of a figure eight. In another construction, the intermediate member extends to the outside of the barrel and has a lug which extends through a recess in the barrel and engages a recess in a skirt or socketed portion on the nib-section. The nib-section or intermediate member may be connected with a cap of the type described in Specification 194,895, so that movement of the cap to uncover or cover the nib automatically places the passages into or out of alignment respectively.

Title: Improvements in or relating to multichannel electric pulse time modulation signalling systems
IPC: H04J3/04
Filed: 1953-10-05
Abstract: 761,246. Multiplex pulse signalling. GENERAL ELECTRIC CO., Ltd., LITTLE, J. G., and ROUS, R. F. Sept. 29, 1954 [Oct. 5, 1953], No. 27298/53. Class 40(5) Relates to a circuit for selecting a channel pulse train from a multiplex train of interlaced phase-modulated channel pulses and converting the relevant pulses into corresponding duration-modulated pulses. The negative channel gating pulses from terminal 10 render valve 1b non-conducting to condition valve 1a, to become conducting when the next channel pulse is applied to terminal 7, the valves 1a, 1b having a common cathode resistor 2. The resulting channel pulse at the anode of valve 1a is applied through condenser 40 to the grid of valve 30a, to trigger the two-condition circuit comprising valves 30a, 30b. Upon cessation of the gate pulse at terminal 10, the damped inductor circuit 4, 5, 6, in the anode circuit of valve 1b produces a short negative pulse which is applied through rectifier 41 to the anode of valve 30a to restore the trigger circuit to its original condition. The resulting duration-modulated pulse in the anode circuit of valve 30b is passed through the transformer 43 and low-pass filter 44 to the signal reproducer 45.

Title: Improvements in or relating to multiple speed electric motor drive systems
IPC: H02P7/06
Filed: 1951-11-23
Abstract: 696,267. Driving sound reproducing machines. DICTAPHONE CORPORATION. Nov. 23. 1951 [Nov. 29, 1950], No. 27523/51. Class 40 (ii) [Also in Groups XXXV and XXXVII] A shunt motor 2 drives the mandrel of a recording and reproducing machine 6 and is adapted to be energized from either alternating-current or direct-current mains through a supply plug 8. The motor field winding 22 is connected to the mains through a rectifier 16 and a series filter resistance 18, a filter condenser 26 being connected in parallel with the field winding. For use in recording a switch 39 is moved to the position shown and the motor armature is connected to the supply through a filter resistance 34, a second filter condenser 36 being connected in parallel to the armature. A switch 38 controls an adjustable armature resistance 32 for two-speed operation of the motor, and when the switch is in the low speed position, it connects the armature winding to a tap 52 in the field winding so that changes of load will cause interchange of currents between the armature and field circuits in such a manner that the motor is operated at substantially constant speed. resistor 48 may be included in the connection between the armature and the tap 52, and additional fixed operating speeds may be provided by extra taps on the field winding 22 and the resistor 32. To prepare for reproduction operation, ganged switches 39 and 56 are moved to connect speedcontrol potentiometer 64 and resistor 66 across the supply and to connect the motor armature to adjustable tap 82. When the motor is operating at low speeds the portion of resistance 64 which is added to the resistor 66 in parallel with the armature forms a low-resistance shunt so that the motor operates at a steady speed. When backspacing operation is initiated switch 74 is opened to remove the resistance in shunt with the armature of the motor and to increase the speed thereof. Specification 696,268, [Group XXXV], is referred to.

Filed: 1950-11-20
Abstract: 685,089. Water supply. CHANCE BROS., Ltd. Aug. 22, 1951 [Nov. 20, 1950], No. 28289/50. Class 68(i) [Also in Group XXIX] A closed water storage tank a is supplied by a submerged pump f driven by an electric motor controlled by a switch g responsive to the pressure of air in the tank, and a venting valve h loaded by two springs, one of which is controlled by a float, controls the air pressure in the tank. When the water in the tank is at its upper level, the float x is in such position that a thimble v allows a spring abutment t to engage a collar u on the spindle o of the valve so that the valve member m is loaded by both springs p, r, permitting a relatively high pressure to be attained in the tank to stop the pump motor. As the water level falls, the float relieves the pressure of the spring r on the valve member to allow it to vent the tank to a lower pressure. The pump is restarted when the air pressure has fallen sufficiently. The supply pipe between the pump and the tank has check valves e, d permitting the entry of air when the pump is inoperative so that each time the pump is started a certain amount of air is delivered to the tank. If, due to faulty working, the pressure in the tank rises above that at which the pump should be stopped the valve h acts as a safety valve.

Title: Ball mill apparatus
Inventor: SMITH EDWARD W
IPC: B02C17/14
Filed: 1954-10-04
Abstract: 754,070. Ball mills. VIBRO DYNAMIC ENGINEERING, Inc. Oct. 4, 1954, No. 28484/54. Class 59. Ball mill apparatus comprises a pair of ball mill drums mounted in spaced axial alignment for free linear axial movement and for axial rotation, the linear axial movement being effected by means applying forces acting wholly between the drums and parallel to the axes thereof for oscillating the drums simultaneously towards and away from each other. One of the drums may be replaced by a body equivalent thereto for balancing the oscillating movement which preferably takes place with a resonant frequency. The drums are moved towards each other electromagnetically and away from each other by springs. In the form shown, rotatable ball mill drums 1, 1<SP>1</SP> mounted in bearing supports 2, 2<SP>1</SP> have non-rotatably secured to the inner trunnions thereof seats 8, 8<SP>1</SP> between which springs 9, 9<SP>1</SP> are secured. Also mounted between the seats 8, 8<SP>1</SP> is an electromagnetic driving means comprising armature and field elements 12, 13 which are energised, when current flows through a coil 15, to move the drums 1, 1<SP>1</SP> towards each other. This movement continues until arms 29, 30 contact pins 27, 28 projecting from a switch box 26 to open normally-closed limit switches and break the circuit through the coil 15. The drums then move away from each other under the action of the springs 9, 9<SP>1</SP> until a plate 26<SP>1</SP> secured to the outer trunnion of drum 1 contacts a plate 25<SP>1</SP> to close contacts, 21, 22 Fig. 4, and energise a coil 18 in circuit with the coil 15 so that the latter is again energised to move the drums towards each other. The limit switches are connected in parallel with each other to that oscillation is prevented if the drums are unequally loaded. The position or length of the arms 29, 30 may be altered if it is desired to operate with drums having different masses. In a modification, Figs. 5 to 7 (not shown), the drums, their bearing supports and their driving motors are mounted on a platform which is movable on ball bearings on a base.
