Title: Electromagnetic device
IPC: H02K7/065
Filed: 1959-11-03
Abstract: 888,850. Ratchet gearing. GLOBE INDUSTRIES Inc. Nov. 3, 1959 [Nov. 7, 1958], No. 37330/59. Class 80 (3). In electromagnetic ratchet gearing wherein a shaft 12 carries a ratchet wheel 64 engaged by a pawl 52 on a spring-loaded rotor 16 which is oscillated by intermittent energization of a coil 40, any movement of the shaft 12 when the rotor is in either of its extreme angular positions is prevented by a spring-loaded locking lever 92 on a fixed pivot 90, the lever 92 being forced against the teeth of wheel 64 by levers 46, 48 actuated respectively by pins 42, 44 on the rotor 16. The levers 46, 48 and 92 are pivoted on a fixed apertured plate 72. The coil 40, carried in a spool or a plastic capsule, is mounted in a preferably ferromagnetic case 2 having non- magnetic end bells 4, 6 supporting the preferably non-magnetic shaft 12. The rotor 16 is attached to a complementary rotor 14, the rotor poles co-operating with poles on stator rings 30, 32 fixed in the case 2. A preferably non-magnetic torsion spring 15, Fig. 1, urges the rotors to the rest position shown in Fig. 2, wherein the pin 44 on rotor 16 presses against the lug on one end of lever 48 to cause its other end to force the lever 92 against the wheel 64 and so prevent any movement of the wheel. When the coil 40 is energized the rotors 14, 16 move clockwise, thereby releasing the lever 92 and causing the spring-loaded pawl 52 pivoted on the rotor 16 to rotate the wheel 64 until the pin 42 on rotor 16 engages the lug on lever 46. This engagement 42-46 stops the rotors and again forces the lever 92 against the wheel 64 to prevent overrun. The coil is then deenergized and the rotors return to the Fig. 2 position. In a modification the cranked lever 92 is replaced by a straight pivoted arm, the ends of the levers 46, 48 acting thereon through a slidable pin.

Abstract: 1,127,951. Route setting; controlling vehicles; motor fare carriages. F. JUNGHEINRICH. 6 Sept., 1965, No. 38025/65. Headings B7H and B7N. In a transporting arrangement in which industrial trucks 1 which can be manually controlled by means of a tiller arm 7 are automatically guided by a wheel 11 which engages in a fixed groove track 12, means are provided on the vehicle, responsive to the detection of a track side marker 25 at diversion points 27 on the track, for guiding the wheel 11 into a branch track 24. Each truck 1 is self propelled and in the arrangement shown the single driven wheel 3 pivots about a vertical axis 5 for steering purposes. The tiller arm 7 is raised for automatic control and the arm 10 carrying the guide wheel 10 is swung upwards to the dotted line position for manual control. The markers and sensing elements may be co-operating magnetic elements or they may be raised members, Figs. 13, 16 (not shown), or a trough member, Fig. 14 (not shown), and the movement imparted by these members to a sensing element on the vehicle operates a switching circuit. In the arrangement shown in Fig. 15, the marker is a conducting plate positioned adjacent the track 114 and the sensing element includes a pair of brushes 136, 137 which complete the switching circuit. The sensing elements are lowered to a position in which they can co-operate with the markers under the control of a programmer on the vehicle which in turn can be controlled by the distance travelled by the vehicle. A number of means are disclosed for guiding the wheel 11 into a branch track all of which urge the wheel towards the side of the track from which the diverging track branches. In Fig. 6 (not shown), a member on the vehicle is rotated to bring a wheel into contact with an outside edge of the track, thereby to urge the wheel 11 towards that edge. A magnetically operated arrangement is shown in Figs. 8 and 9 (not shown) and an hydraulically operated arrangement is shown in Fig. 10 (not shown). In the arrangement shown in Fig. 12, operation of the switching circuit by a sensing element actuates a drive motor 101 and a clutch 100, whereby the motor housing which is vertically pivoted at 5 is rotated to move the wheel 11 to the required side of the track. The arm 10 can be formed in two parts hinged together so that if the wheel 11 strikes an obstruction the arm collapses and operates a switch which shuts off the vehicle drive and applies a brake.

Abstract: 1394178 Fuel injection pumps PERKINS ENGINES Ltd 10 Aug 1972 [16 Aug 1971] 38352/71 Heading F1A In liquid fuel injection apparatus comprising a rotary distributer type fuel injection pump 11 supplied with fuel by a feedpump 9 through a passage 17, 20 containing a metering valve 15 controlled by a speed governor 13, the injection timing is advanced in response to increasing feedpump pressure and is additionally advanced if light engine load conditions causes the governor 13 to reduce the opening of the metering valve 15 below a predetermined value. The injection timing is adjusted by a piston 40, Fig. 2, slidable in a bore 41 and having a transverse bore 43 which receives a radial pin 38 attached to the rotatable cam ring 28 of the pump. The feedpump pressure acts continuously on the left hand end of the piston 40 via a line 45, whereby, as the feed pressure increases the piston 40 moves against a spring 46 to advance the injection. The spring 46 bears against a loosely fitting plunger 49 in a chamber 47 connected to a tank 1 via a port 48. In turn the plunger 49 bears against a piston 51 urged to its extreme left position in a cylinder 50 by feedpump pressure communicated to a cylinder space 60 through the metering valve 15 and a passage 58, 59. When light load conditions causes the governor 13 to move the valve 15 below the predetermined value, the passage 58, 59 is connected by a passage (not shown) to the tank 1. This allows the pistons 40, 51 and the plunger 49 to move rightwards thereby additionally advancing the injection. The valve 15 comprises a valved spindle 19 rotatable by a rod 36 attached to a lever 34, the lever being loaded at one end by a spring 37 manually adjustable by a speed control lever 65 and at the other end by the movable sleeve 33 of the governor.

Title: Method for producing titanium, zirconium, cerium, hafnium or thorium
Inventor: JAZWINSKI STANISLAW TEODOR
IPC: C22B5/20
Filed: 1956-12-17
Abstract: <PICT:0828238/III/1> Titanium, zirconium, cerium, hafnium, or thorium are obtained by heating an oxidic ore thereof, under elevated pressure in excess of 2 atms., with sufficient carbon to convert available oxygen in the ore to carbon monoxide and with sufficient additional CO for the compound M(CO)7 to be formed, where M is the metal, distilling off the M(CO)7 formed, and dissociating the distilled M(CO)7 by heating under atmospheric pressure to precipitate the metal and release CO.  Finely divided rutile and activated carbon is charged through 12 into pressure vessel 10, and is agitated by stirrer 11, while being heated to 300-800 DEG  C. by burners 16 or resistance coils.  Excess CO enters at 13 and the pressure should be 2-10 atmospheres, which may be maintained by CO only or by addition of inert gas, e.g. helium or argon. Preferred conditions are 400 DEG C. at 4 atms.  When the speed of reaction has fallen appreciably, as indicated by CO absorption, the temperature is raised 50-100 DEG  C. to distil the Ti(CO)7 into precipitation vessel 17 which is isolated by valve 20.  The temperature is raised a further 50-100 DEG  C. by burners 24, when titanium is deposited.  The CO is purged through 22 by inert gas, e.g. helium or argon, entering at 21 and may be recycled to pressure vessel 10.  A cascade of precipitation vessels may be used to ensure complete recovery of the titanium.

Title: Induction brake speed control for elevators
Inventor: MITCHELL OMERY EDWARD
IPC: B66B1/32
Filed: 1964-09-22
Abstract: 1,034,727. Automatic speed control. TURNBULL ELEVATOR Ltd. Sept. 22,1964, No. 38650/64. Heading G3R. [Also in Division H2] An A.C. motor driving a lift is associated with an electro-magnetically released friction brake and a D.C.-operated induction brake having coils 1B,2B in series with relays 1BC,2BC. These relays have contacts for operating relays which change to rotor resistance of the motor in response to changes in the braking current so that the rotor resistance is decreased when the braking current decreases. A rectifier V1, V2 supplying brake coils 1B,2B is controlled in accordance with a pattern voltage which is developed across capacitor C10 and represents the desired motor speed, an opposing sample voltage being developed across resistor R29. In addition, the rectifier is controlled by a derivative voltage across capacitor C12 and proportional to the rate of change of brake current, and by an alternating rider voltage which is developed across resistors R16, R17 and is 90 degrees out of phase with the voltage supplying the rectifier. The sample voltage is derived by rectification of the voltage across motor slip-rings N1,N2, N3; and is maintained substantially constant for any constant motor speed despite changes in the rotor resistance caused by the relays 1BC,2BC. For this purpose, resistors R27, R28 are associated with contacts 3A5, 2A5 on the resistance-changing relays. The pattern voltage increases smoothly to a constant value representing a desired landing speed, the rider voltage decreasing progressively as the car approaches a stopping floor. The friction brake is applied if a predetermined amount of current in brake coils 1B, 2B is not provided within a given time after the initiation of car deceleration. Failure of the slip-ring voltage to rise to a predetermined amplitude within a given time after the beginning of car deceleration also causes the friction brake to be applied. Failure of the slipring frequency to rise to a given value within a given time after the car has arrived at a set distance from the stopping floor causes the friction brake to be applied immediately. Energization of the brake coils 1B, 2B may continue until the car is stopped, after the motor and friction brake have been de-energized.
