Title: Improvements in chimneys for liquid fuel burners
IPC: F23D99/00
Filed: 1940-02-19
Abstract: 534,423. Oil stoves. MANTLE LAMP CO. OF AMERICA. Feb. 19, 1940, No. 3142. Convention date, March 4, 1939. [Class 126] An oil stove 10 has a central chimney located above the burner 36 and formed in two parts 22, 26. The upper part 22 is rigidly secured at its lower end to the stove casing and free to expand upwardly between lugs 27 while the lower part 26 is rigidly secured to the burner and movable with the burner and its oil reservoir 29 when the latter is moved into and out of the stove in the guides 28. The lower end of the upper chimney part 22 engages by means of pins 31, Fig. 9, slots 30b in a ring 30 which rests by means of lugs 30a upon a flange 26c of the lower chimney part 26 so that a space is provided between the ring 30 and lower chimney part 26 for the admission of air to the chimney. The arrangement of the pins 31 and slots 30b is such that when the lower chimney part is moved with the burner and its reservoir the ring tilts by gravity about the pins and allows free movement either into or out of the stove of the lower chimney part 26 and the burner.

Abstract: 1516932 Receiver for selective calling system DAINI SEIKOSHA KK 27 Jan 1976 [28 Jan 1975] 03156/76 Heading G4H A receiver for a selective calling system operating with digital calling messages includes a succession of stores M1-Mn, means actuated upon receipt of a message for storing that message in one of the stores and shifting any message previously stored in that store to the next store in the succession, and means S2- Sn+1 for reading out messages stored in the stores. A received message is passed to a discriminator 4 (Fig. 2, not shown) where its address is checked to produce an audible signal 5 if the address is correct; data applied to the discriminator is passed to a display 6 via a gate 51. Subsequent messages cause data to pass through stores M1-Mn until the first message is in Mn. An operator can then select any store for display by means of pushbuttons (MCl-MCn) in a unit 8 which enable the corresponding one of gates S2-Sn + 1 while blocking gate S1. In an alternative embodiment, push-buttons (MC) may be replaced by a single pushbutton and a rotary or other distributing switch.

Title: Improvements in and relating to the treatment of liquid mixtures containing aldehydes
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C45/50
Filed: 1951-02-12
Abstract: An aldehyde-containing liquid mixture which also contains residual cobalt and/or a cobalt compound catalyst, such as an aldehyde mixture obtained by reacting an olefine with carbon monoxide and hydrogen at elevated temperature and pressure, is subjected, immediately following the production of the mixture, to a flash distillation in which the aldehyde is recovered in an overhead fraction. Condensation and/or polymerization of the product upon storage is thereby effectively suppressed.  The manner in which the flash distillation may be carried out is described in the parent Specification.

Abstract: 1,154,125. Measuring fluid-pressure, electrically. STATHAM INSTRUMENTS Inc. Jan.25, 1967, No.3741/67. Heading G1N. A fluid-pressure transducer comprises a diaphragm having a central boss 111 Figs. 1, 2 and an annular flexible area 116 to which resistance strain gauges are bonded, the radius of the boss being approx. 0À3 to 0À8 times the flexible area radius and the boss thickness being at least twice the flexible area thickness. In Fig. 1 the diaphgram is attached to or is integral with a ring 112 and pressure acts in the direction of arrow 120. The diaphragm may be insulative e.g. quartz, or may be stainless steel coated with silicon oxide. The strain gauges are connected to form a Wheatstone bridge, one pair of opposite arms of which comprises tensionally stressed radially extending strain gauge segments 122, 124 and 126, 128 Fig. 2, and the other two opposite arms comprise compressively stressed radially extending strain gauge segments 130, 132 and 134, 136 respectively. The gauge segments may be formed by an electro-deposited film of silicon-chrome, or nickel-chrome and are joined by chrome tabs (e.g. 138, 140, 142) and connected to form a bridge by wires (e.g. 144, 146, 152, 154).

In an electromagnetic clutch an axiallyengaging positive dog clutch, operated by the same magnetic coil as an axially-engaging friction clutch, is engaged after a reduction of the air gap between the discs of the friction clutch. A magnetic member 1 having a magnetic coil 2 is keyed to a shaft 3 and has a drive-ring 4 secured thereto carrying outer clutch discs 5 cooperating with inner clutch discs 6, keyed to the splined hub 7 of a gear-wheel 8. An axiallymovable armature disc 9, also keyed to the hub 7, carries a clutch-ring 11, with dog-clutch teeth 12, slidably mounted on its periphery and prevented from relative rotation by coupling pins 17 engaging half in the disc 9 and half in the ring 11.
