Title: Improved mechanical counter
IPC: H03K21/08
Filed: 1963-01-15
Abstract: 978, 553. Counting-apparatus; electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 15, 1963 [Feb.15, 1962], No. 1758/63. Headings G4D and G4H. A mechanical counter is provided with cams for the operation of associated contacts to provide electrical read-out when a scanning bail is pressed against the digit wheels. The digits on each wheel are visible through a window in a casing 18. Each flat face of the wheel bears a small cam 19 differentially spaced along the face so that when it is opposite a bail 22 it represents the digit seen through the window. The bail carries a set of contacts 24, Fig. 6 and a set of denominational conductors 29, Fig. 4, so that when the bail is pressed against the digit wheels by cam 31 read-out is effected on the cross-bar principle, denomination by denomination. Subsequent operation of bail 38 by cam 35 wipes the contacts for cleaning purposes. Bails 22, 38 may be modified (Fig. 3, not shown). Counting system. Pulses to be counted from two sources energize solenoid 51 or 55, respectively to control the escapements of spring-driven motors 49, 53. Step motion is thus applied in known manner to the lowest order of two counters. Three numeral wheels on the left are manually settable through wheels 47 to a customer's order number. To effect read-out solenoid 62 is energized. A short first pulse advances clutch mechanism C1, Fig. 9, to position a, whereby clutch drive 66 to the counters is disengaged but incoming pulses are stored by the spring motors. A short second pulse advances C1 to position b to rock bail 22 and effect electrical read-out. A further pulse advances C1 to c to lift the bail 22. If a central station receiving read-out requires a fourth pulse is sent to advance C1 to position d to repeat readout. A long pulse takes the mechanism to position O at which normally stationary shaft 12 is rotated once to carry all numeral wheels to zero position. Read-out may be initiated by a self-latching button 72.

Title: Improvements in, or relating to, protective devices for consumers' electrical apparatus
IPC: H02H3/14
Filed: 1935-01-19
Abstract: 450,362. Electrically released switches. SADLER, A., 65, Temple Row, Birmingham.-(Schiele & Bruchsaler Industriewerke Akt.-Ges.; Baden-Baden, Germany) Jan. 19, 1935, No. 1834. [Class 38 (v)] A leakage - current - operated device of the type in which the coil is connected between an apparatus - frame and earth and trips the supply-switch when a predetermined leakage occurs, has the coil, armature and a testing device assembled as a unit which is thereby adapted to be so fitted to an automatic switch that, on the armature being attracted by either leakage or testing current, it will trip a catch normally holding the switch contacts in closed position. As applied to a push-operated switch as described in Specification 447,688, the leakage coil 2 with its core 6, poles 7, 8, and armature 2a, is mounted on a base 1 to which an earthing terminal 11 anchors a metal strip 12 serving to receive a push-button 13. The testing device is of the character described in Specification 447,342. A block 17 on the button carries a contact arm 4 co-operating at the free end with a testing resistance 3a and intermediately at a rib 4a with a similar resistance 3b, the resistances being connected to separate supply conductors and being connected in turn, firstly 3a and then, by further depression of the button, the rib 4a engages the resistance 3b and causes the end to move clear of 3a. The bent-over end of 12 is serrated to form, with corresponding serrations on a plate 18, a safety spark gap in parallel with the coil 2 between the apparatus frame and earth. A recess may be formed in the bobbin 5 under the spark gap to prevent carbonization and the resulting formation of a conducting path. The armature 2a is arranged to trip a catch when a predetermined leakage current flows in the coil.
Patent GB-414100-A (GB)
Title: Improvements in and relating to the manufacture of moulded or otherwise shaped articles such as sheets, tiles or pipes of cement, concrete or the like
IPC: C04B41/47
Filed: 1933-01-19
Abstract: A method of manufacturing moulded or otherwise shaped articles such as sheets, tiles, pipes, electric fuse handles, &c. from inorganic binding-agents, with or without fillers, in which one or more easily oxidizable oils are incorporated in the articles either by impregnation after shaping or by incorporation in the mixture of ingredients before shaping, is characterized by subjecting the articles, after shaping and after the binding-agent has set, to a heat treatment to oxidize and/or polymerize the oils.  The binding-agent may be Portland cement, or other hydraulic binding-agent or plaster, the oils may be linseed, rape, or china wood, and the fillers asbestos, animal or vegetable fibres, wood pulp, or mineral aggregate.  In an example, grey sheets 1/2 inch thick, made from Portland cement, asbestos, and a little powdered bitumen by moulding under a pressure of 3 tons to the square inch, are allowed to mature, dried by heating at 100 DEG  C. for 12 hours and then 188 DEG  C. for 18 hours, and placed in a steam-heated autoclave, which may be first evacuated of air, where they are impregnated with linseed oil under a pressure of from atmospheric to 50 lbs. per square inch for 12 hours.  The sheets are removed, may be allowed to drain and air-dry for a few days, and are placed in an oven at 80 DEG  C. at which temperature they are kept for 24 hours. The temperature is then gradually raised during two hours to 350 DEG C., maintained there for two hours, and finally raised to 500 DEG  C. and kept there for an hour. Preferably, before or after the heat treatment a flame is applied to the surface of the sheets, burnt oil being formed and sealing the surface.  For very thin sheets-e.g. 1/8 to 1/4 inch thick-the heat treatment may consist in subjecting them to the action of a flame.  Impregnants other than the oils, such as bitumen, pitch or synthetic resin, may be incorporated in the articles at any stage of manufacture.

Title: Electrical voltage regulator
IPC: H02P9/20
Filed: 1946-01-21
Abstract: 619,955. Automatic control. BENDIX AVIATION CORPORATION. Jan. 21, 1946, No. 1952. Convention date, Jan. 23, 1945. [Class 38 (iv)] Voltage.-The voltage of an alternator 23 is regulated by a carbon-pile regulator in series with the shunt-connected field-winding 8 of the exciting generator 1, the regulator having (1) a main and comparatively slow-acting winding 75 energized over a rheostat 62 in accordance with the voltage between phase wires 30, 31; (2) a somewhat more quickly operating winding 55 shunted across the winding 8; and (3) a quick-acting winding 50 in series with winding 8 but receiving current also in opposition from a transformer 42 and rectifier 85 in accordance with the load on the alternator. The effect of the association of windings 50, 55 with winding 8 is to oppose the changes in the current in winding 8 dictated by the main regulator winding 75 and so to prevent hunting. A droop of the voltage/load characteristic is prevented by the opposing current in winding 50 derived from the transformer 42. Specification 608,508 is referred to.

Abstract: 394,412. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc., Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.-(Assignees of Carlson, B. G. ; 42-05, Layton Street, Elmhurst, New York, U.S.A.) Jan. 22, 1932, No. 1991. Convention date, April 29, 1931. Addition to 393,354. [Class 97 (iii).] The air-driven gyroscopes described in the parent Specification are modified in that means are provided on the rotor other than the rotor blades or buckets for impingement by an air jet or jets upon inclination of the rotor bearing frame, thus producing a restoring torque. In the form shown, the rotor is provided with buckets 22 terminating in circumferential walls 23, 24. The driving jets 20, 21 are carried by the vertical ring 6 and are spaced so that their outer edges lie adjacent the inner edges of the walls 23, 24. Upon inclination of the rotor one or other of the jets impinges on the adjacent side wall and exerts a restoring torque about the vertical axis. Alternatively a single jet 31 may be arranged symmetrically with respect to a knife edge circumferential wall 26 arranged near the central plane of the rotor so that upon inclination of the rotor the jet exerts a side push on the wall giving rise to a restoring torque about the vertical axis.

Abstract: 854,326. Viscosity comparators. GORDON, M. S. Jan. 21, 1958, No. 2001/58. Class 106 (2). A viscosity comparator comprises a pair of spaced-apart cups 31 of equal size and shape, each having a central opening in the bottom thereof, a pair of liquid containers 35 located beneath the cups 31 and means 30 interconnecting the cups and slidable on a vertical guide 22 whereby the cups can be simultaneously dipped into and withdrawn from the containers. The cups 31 are suspended from a platform 28 which slides on a pair of guides 22 attached to a case 10, in which the comparator is carried, the liquid containers 35 resting on the base of the case. The case also contains a syringe 16, a thermometer 17, a stirring rod 42 and apparatus for testing oil for properties other than viscosity. In use, oil for the test and a standard sample are placed in the containers 35, 36, and the temperatures allowed to equalize. The cups 31 are then lowered into the containers, filled with oil, and raised again, being held in the raised position by a spring clip 27. The viscosities of the two samples of oil are compared by noting from which cup 31 the oil first stops flowing. That cup will contain the less viscous oil.
Patent GB-400612-A (GB)
Title: Improvements in fuzes for projectiles
IPC: F42C15/16
Filed: 1932-01-22
Abstract: 400,612. Projectile fuzes. ALIQUO, F., 138A, Via Emanuele Filiberto, Rome. Jan. 22, 1932, No. 2021. Convention date, Jan. 23, 1931. [Class 9 (i).] Relates to gyroscopically controlled devices for timing the firing or the arming of projectile fuzes and consists mainly in that the gyroscope is kept spinning by a current of air during the flight of the projectile after it has been unlocked and started at the moment the shot is fired. The gyroscope 2, Fig. 6, may have two or three degrees of freedom; it may be unlocked bv the set back of an inertia bolt or lever, and it may be started by a spring, or by centrifugal racks, or by racks subjected to tangential inertia. During flight, air is admitted by a nose opening 6, and directed through a hole 9 in a disc 17 or a sphere onto ribs or recesses on the gyroscope 2, after driving which, the air escapes through a lateral hole. Or the air is led to the gyroscope through passages in the suspension members of the gyroscope. The rotation of the gyroscope, which keeps its direction in space, relatively to the projectile, which is spun by the rifling, is transmitted through gearing 5 to a pinion 19, Fig. 7, which when the shot is fired becomes engaged by a wheel 18; and this wheel is at the same time coupled by a clutch 24, 25 to a pinion 26 in mesh with a wheel 79 provided with a pin 28 or a recess 29 or a cam 31, Fig. 8, for releasing the firing-pin. The pinion 19 is set by a hand wheel 21, and the wheel 18 by a hand wheel 20 to which it is normally keyed by a pin 22. When the shot is fired, the wheel 18 sets back by inertia, leaving the wheel 20 and engaging the pinion 9. The cam is adapted to release a lever 33 which is then pulled by a spring 37 out of a notch in the firing pin 38. To prevent accidental premature operation, the cam 31 is provided with a finger 66<1>, which is stopped by a pin 67<1> until this sets back by inertia when the shot is fired. For further safety, the firing-pin 38, Fig. 9, may be locked by a centrifugal bolt 41 working in a small chamber 42 provided with an outlet 43 so arranged that the rather high air pressure which occurs while the projectile is travelling through the gun prevents the outward movement of the centrifugal bolt' which can only take place after the projectile is well beyond the muzzle of the barrel. A similar bolt may be used to unlock the gyroscope. The Specification as open to inspection under Sect. 91 describes also a number of safety devices including centrifugal shutters, catches for preventing the return of the safety devices, and the centrifugally operated safety devices comprising screw spindles and spring or air operated delaying brakes, now forming the subject-matter of Specification 400,667. This subject-matter does not appear in the Specification as accepted.

Title: Interlocks for sewing machines
IPC: D05B3/20
Filed: 1922-01-24
Abstract: 196,388. Fairweather, W., (Singer Manufacturing Co.). Jan. 24, 1922. Starting and stopping gear.- Power-operated sewing machines are provided with starting and stopping means having interlocking devices whereby starting is prevented while a work-clamp, presser-foot, &c. is displaced from sewing position and accidental displacement of such part is prevented when the machine is running. In the application to a label-cutting and sewing machine, a presserbar 6 co-operates with a clampfoot 12 and a feed-slide 53. The main shaft carries fast and loose pulleys 17, 18 associated with a belt-shipper 22 mounted on a stop-lever 19 manually operated by a lever 28 against the pressure of a spring 27 to throw the belt on the fast pulley. The stop-lever is held in driving position by a spring latch 25, which is released to effect the stoppage of the machine by a lug 26 on the pattern-wheel 15. A stop-arm 33, pivoted at 31, carries in a lateral extension a stop-screw 35, which lies in the path of the lever 19. The arm 33 is connected by a link 38 to one arm 40 of a three-armed lever, another arm 43 of which is connected by a link 44 to a lever 45, 48 engaging the presser-bar 6. A spring 51 tends to hold the lever 45, 48 in the position corresponding to the stitching position of the presser-bar. The lever may be moved to lift the presser-bar when the machine is not running by a chain 50, by which the toggle 38, 40 is straightened, the stop screw 35 being consequently moved to prevent the inward motion of the stop-lever 19 to start the machine. When the machine is running, the lever 19 is locked in position to prevent the movement of the arm 33 and the lifting of the presserbar. The feed-slide 53 is controlled through connection with the third arm 52 of the lever.
