Title: Improvements in or relating to propelling pencils
IPC: B43K21/22
Filed: 1935-08-27
Abstract: 437,640. Pencil holders. CARTER, F., Brantwood, Firs Avenue, Ashton-under-Lyne. Aug. 27, 1935, No. 23922. [Class 146 (iii)] A propelling pencil comprises a part, such as the point, which grips the lead, and a spiral spring held by one end within another part of the pencil and which also grips the lead, the two parts being screwed together so that they separate when rotated in a direction which releases the grip of the spring, and come together when rotated in the opposite direction. Screwed into the body a, Fig. 3, is a holder c, to which is soldered a spiral spring d, one end of which is reduced so as to grip the lead. The lead may also be gripped by a second spring h, united to a cap f screwed upon the holder c, or by the split end g of the cap, which may be threaded internally. When the cap f is partly unscrewed, the lead is released from the grip of the spring d and drawn forward, and when the cap f is screwed back the lead is held by the spring d and slides through the spring h or portion g. In alternative constructions the cap f and body a may be integral and the holder c may pass freely through them and be screwed into the rear end of the body a; or, as shown in Fig. 4, the spring d may be held in a recess in the holder c, which is slotted at i to engage one end of the spring and turned over at k to retain the spring, so that the movement of both ends is limited, and forcing of the spring is prevented.

Patent GB-484958-A (GB)
Title: Improvements in or relating to the refining of pig iron and the production of steel or alloy steels
IPC: C21C3/00
Filed: 1937-09-06
Abstract: Refined iron is produced from pig iron by supplying molten pig-iron to a puddling furnace in which the iron is maintained at a temperature above its melting point, removing carbon by the addition of iron ore &c. and simultaneously removing silicon and manganese by an air blast, the latter being stopped when these impurities have been removed to the desired extent and before any substantial amount of carbon is removed.  The air blast may be passed over the surface of, or through, the charge.  To produce steel or alloy steel, the refined iron from the puddling furnace is transferred to an electric furnace, the temperature raised to 1700-1750 DEG  C., and the necessary alloying or other materials added to the charge.  The pig-iron may be melted in a reverberatory furnace, and a portion of the charge fed into the puddling furnace, the charge in the reverberatory furnace being then made up with more pig-iron.  Sulphur present in the pig-iron may be removed by the addition of soda ash before the puddling and any phosphorus is removed by the addition of a lime slag to the charge in the puddling furnace.  The alloying materials referred to are chromium, nickel, molybdenum and titanium.

Abstract: 1291912 Hose couplings ML AVIATION CO Ltd 28 July 1971 [21 May 1970] 24713/70 Heading F2G An air-conditioning supply hose is connected to an aircraft by a male hose connector 10 comprising longitudinally extending hooks 28 for engaging slots in a female connector (not shown), the hooks being biased by a spring 16 to lie behind the leading edge of the connector, and means for extending the hooks into an operative position A for connection to be made. As shown, the hook members 28 comprise a flat plate member 36 having a hooked end 40 and a shorter plate 38 attached to the plate 36 but having a double bend 42. A cam pin 32 extends between and is attached to the plates 36, 38 which pass on either side of a fixture 44 having a cam slot 34 in which the pin 32 rides. The fixture 44 is carried on a ring member 20 which, together with a sleeve 18, is slidably mounted on a generally cylindrical body member 12. The spring 16 biases the ring 20, and hence the hook members 28 away from leading edge flange 24 and seal 26 against a stop 22. The hooks 40 are thus retracted through apertures 30 in the flange 24 so that they are not damaged when the connector is disconnected. To make connection with a corresponding female connector, handles 48, 50 attached respectively to the body 12 and ring 20, are drawn together against the spring 16 to extend the hooks 40 which engage slots in the female connector and lock therein in position A upon rotation of the connector 10 as a whole. In order to ensure a tight connection, the ring 20 is then rotated by means of the handles 50 to urge back the hooks 40 slightly to position B as the cam slot 34 engages the pin 32 to further compress the spring 16. To release the connector, the reverse procedure is carried out.

Abstract: 1464796 Pump circuit FERRANTI Ltd 14 May 1975 [5 June 1974] 25146/74 Heading H3T A conventional diode pump circuit (Fig. 1, not shown), in which a first capacitor C1 is alternately charged via a diode and connected in series via a switching transistor Q with a second capacitor C2, is modified, Fig. 2, in that the diode is replaced by the base-emitter path of a transistor Q2. As shown, a resistor R3 is of such a value that Q2 just saturates. Q1 and Q2 then operate to maintain the potential of the base of Q2 substantially constant (the base cannot rise because Q2 is saturated, nor can it fall since then Q1 conducts to raise it). In response to a positive excursion at the input 10 to capacitor C1, the capacitor charges via the base-emitter path of Q2, whilst a subsequent negative excursion causes Q1 to conduct and the charges on C1 and C2 to be shared.
