Title: Improvements in Apparatus for Operating Railway and Tramway Points, Signals, and the like.
IPC: B61L7/06
Filed: 1916-01-06
Abstract: 103,134. Railway Signal Co., and Roberts, W. S. Jan. 6, 1016. Visual outdoor signals; slots, reversers, and like apparatus.-Signals and points are operated from a rotating shaft through a centrifugal device which moves the signals or points only after a certain speed is attained. In one form, Fig. 7, a compression spring is included in the mechanism, and in another form, Fig. 4, an electro-magnetic latch is controlled by a switch closed by centrifugal force. For operating points, two devices are arranged to move a rocking cam-plate 45 in opposite directions, according to the direction of rotation of the driving-shaft 41, suitable gearing 42, 43, 44 being fitted for driving the two shafts 1<a>, 1<b> alternatively. The shaft 1 is driven by an electric motor. Each shaft 1, 1<a>, 1<b> carries a crosshead 2 on which are pivoted hell-cranks 3 with weights 4. A collar 7 sliding on the shaft 1 is raised by the centrifugal action, and, either directly or through a compression spring 8, raises a collar 9 pin-jointed to the lever 15, which rocks the spindle 16 and the lever 18, thereby raising the thrust-rod 19. 46, 47, rocking the cam-plate 45, and moving the bell-crank 54 and rod 57. Stops 20, 20<a> on the lever 15 open and close a switch 22 in the circuit of the driving-motor. A slotted lever 25, engaging a pin 28 on the lever 15, is moved towards an electro-magnet 31, which holds it in position to keep the signal at clear after operation until the magnet is de-energized. While the signal is at danger, the lever 25 is held in the position shown by the armature of magnet 40. This magnet is energized to withdraw the armature and allow movement to the levers 25, 15, when a contact-maker 35, Fig. 5, moves outwards by the centrifugal force. A radial rod 37 passing through the cross-head 2 supports a sliding contact-maker 35 drawn inwardly by a spring 36, which is adjustable by rotation of the rod 37 so as to move the nut 37b radially. The contactmaker 35 may engage fixed rings 32, 33, as shown in Fig. 5, or springs 32<a>, as shown in Fig. 6. In the latter case, intermittent contact is made. The semaphore arm may be made of corrugated aluminium alloy. In an alternative form of mechanism for operating signals, the magnet 40 is dispensed with, and a compression spring and a lost-motion pin-and-slot connexion is inserted between the collars 7, 9, the parts being arranged to allow a direct thrust between the collars after a certain speed is reached.

Title: Improvements in or relating to glass
IPC: C01B33/32
Filed: 1951-01-05
Abstract: 678,073. Glass manufacture. DIAMOND ALKALI CO. Jan. 5, 1951 [Feb. 24, 1950], No. 456/51. Class 56. Silica and an alkali metal hydroxide, carbonate, or bicarbonate are mixed together with a mineral oil in an amount sufficient to loosely bind the particles but insufficient to decrease substantially the original free-flow characteristics, and then fused to form alkali metal silicate glasses. Such glasses are formed by heating to about 2500‹ F. in a furnace with oil or gas fired burners, and the presence of the oil in the batch prevents the escape of alkali with the combustion products and the consequent fouling and damage of the apparatus. The mixtures have a mol ratio of Na 2 O to SiO 2  of 1:1 to 1:3.7, the preferred ratio being 1:1.58 to 1:1.37. The oil is suitably a light mineral oil having a viscosity of 30-100 Saybolt Universal seconds, and preferably 40-60 S.U.S. Fuel oils, e.g. light paraffin oils of viscosity 40-60 S.U.S., and oils intermediate the kerosene fraction and on S.A.E. (Society of Automotive Engineers U.S.A.) No. 10 lubricating oil are also suitable. The oil is preferably added in amount of 0.5- 2.5 per cent of the alkali-silica mixture, and desirably 0.5-1.5 per cent. The mixture spreads uniformly over the floor of the furnace. The oil preferably consists only of hydrocarbons since any inorganic content may affect the colour &c. of the glass. The composition of several examples is given and shows the effect of streams of air on the fueling mixtures, and a further example describes the use of such mixtures over a period and the results of such use.

Abstract: 247,351. Tonks, W. H., and Sparks, W. Jan. 12, 1925. Fastenings for doors; registering. - In a coinfreed lock having a counting - apparatus to check the payments, means are provided whereby it is impossible to count more than once a single payment and also whereby it is impossible to fail to register any payment by virtue of which the door has been opened and subsequently closed, even if the inside handle is not manipulated. As shown applied to the lock described in Specification 236,881, the lever 12a of a counter 13 is actuated by an arm 10 pivoted at 11. A projection 12 on the plate or carrier 3 rotated by the outside handle, depresses the arm 10, but this depression is insufficient to actuate the counter. The actuation of the counter is completed by a projection 18<b> on the bevelended slide 18 engaging the end 10<a> of the arm 10, when this slide assumes its outermost position after the door is opened. Since, as described in the above-mentioned Specification. the penny by resting on the projection 18<a> does not drop until the door is fully opened, registration of that penny does not fail to take place even although the outside handle may be operated several times without opening the door. Also since the counter is not fully actuated until the door is opened. it is impossible to register the penny more than once.
