Title: Improvements in or relating to apparatus for testing sand or like granular material
IPC: G01N33/24
Filed: 1936-04-20
Abstract: 454,911. Testing sand and like materials. CHILDE, H. L., Meadowside, Uplands Way, Riverhead, Kent. April 20, 1936, No. 11319. [Class 106 (ii)] A receptacle 1 is filled completely or to a predetermined level with sand in the moist state which sand is then completely dried or saturated whereupon a gauge rod 3 passing through the cover 2 is brought down to touch the new level. The percentage of sand in the same moist condition which must be added to the original volume to give a volume of dry sand equal to the volume of moist sand originally treated is then read off on the dip gauge. The gauge may be provided with a foot piece to prevent sinking into the sand. Instead of a separate scale as above the scale may be marked on the inside of the test vessel. If desired the scale may indicate directly the total volume of moist sand required to give a volume of dry sand equal to the original volume of moist sand tested.

Abstract: 1343253 Clutch-brake combinations; electromagnetic clutches; full face disc brakes; slack adjusting BENDIX CORP 10 March 1972 [31 March 1971] 11338/72 Headings F2L F2C and F2E In an electromagnetically operated clutchbrake combination, energization of the stationary electromagnet 16 moves an armature 54 to engage multidisc friction clutch 34, 36 and adjust the clutch actuating presser member 60 for wear of the clutch, and de-energization of magnet 16 causes brake 160, 90 to be actuated by spring 85, the clutch being disengaged and the brake also having means for compensating for wear. In clutch engagement the torque is transmitted between members 38, and 22, the member 90 being stationary for braking purposes. The presser member 60 of the clutch is helically splined to armature 54 and a split spring ring 70 is incorporated such that if, on magnet 16 being energized, the member 54 abuts the driving member 22 before the clutch disc pack is engaged due to wear thereof the member 60 screws along the helical splines to compress the disc pack, but is prevented from screwing back on disengagement so that the adjustment is maintained. The brake is adjusted in similar fashion, friction member 160 being helically splined to an adjusting member 154 which screws the member 160 leftwards if it contacts a vertical portion of member 90 before the cone surfaces 92, 162 engage, split spring 170 preventing relative rotation between members 154, 160 in the opposite direction so that the adjustment is maintained. The radial extension 63 of the member 60 passes between axial extensions 40 of the driven member 60, on which extensions the discs 36 are splined, and passes through similar extensions 140 of the brake assembly so that the driven member 38 is braked by the brake.

Title: Improvements relating to electric signalling systems
IPC: H04Q3/00
Filed: 1933-04-19
Abstract: 418,306. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, both in London. April 19, 1933, No. 11418. [Class 40 (iv).] In an electric signalling system comprising a pair of signal receiving relays P, PA connected to a signalling wire, the operation of one or other of the relays being dependent on the direction of current flow, a potential always applied at a certain stage in the signalling operations is adapted to operate one of the relays (P), but a prior application of potential or potentials prevents the operation of this relay and determines whether the other relay (PA) shall operate. The signalling may be between two points connected by a hunting switch and the potential for operating PA is applied when the receiving point is picked up but is removed subsequent to a switching operation completing the connection between the two points. The arrangement shown comprises two selecting stages S1, S2, the switches of which are driven by electromotors normally locked by electromagnetic latches and controlled by common marker circuits CC1, CC2. S1 is regarded as the transmitting point and S2 the receiving point. At S1, contacts e, f of relays (not shown) may be both open, both closed, or either closed, according to the route to be take at a subsequent stage, or to the class of calling subscriber (for signalling an operator), while at S2, the two signal receiving relays P, PA are connected to the positive wire over oppositely poled rectifiers r1, r2. The contacts k of the coupling relay (not shown) at S1 are closed and assuming f closed and e open, booster battery AB is connected to the positive wire when latch magnet contacts lm close on termination of the hunting movement of S1. Signal relay PA therefore operates and may, if desired, lock up. Shortly afterwards, S1 switches through at 1h and signal relay P is operated over the calling loop in series with 2A. P may also lock up, but as shown is released by b. Relay PA should be made quick to operate or the contacts 1h of the switching relay should be sufficiently slow to allow PA to operate. PA is also provided with a slug to absorb the back kick when it de-energizes as this might operate P. If contacts e are closed, P is short-circuited when the switch through occurs and remains inert. The negative and any other wire may be used for similar or other signalling purposes. According to the Provisional Specification, the relays P, PA may be polarized.

IPC: C10L5/08
Filed: 1946-04-15
Abstract: A moulding powder is produced by heating rapidly a cyclic carbon compound other than coal, e.g. naphthalene, anthracene, phenanthrene, coal tar, or coal tar pitch, in an inert atmosphere, to a temperature which produces intumescence, e.g. 350-550 DEG  C., cooling and powdering the product, moulding to desired shape and heating under non-oxidizing conditions, sufficiently rapidly to produce agglutination but not to cause intumescence, to a temperature above 550 DEG  C. and preferably above 700 DEG  C.  The cyclic compounds may be obtained in a high degree of purity by distillation.  If they are liable to volatilize during heating, condensation or polymerisation may be effected, with the aid of a catalyst such as aluminium chloride on benzoyl peroxide if necessary, or by reaction with a small molecule such as formaldehyde.  The powder may be mixed with a lubricant or diluent such as graphite.  Heating may be effected at sub- or super-atmospheric pressure and the non-oxidizing atmosphere may contain a gas such as ethylene adapted to deposit carbon in the pores of the product.  Specification 494,676, [Group XII], is referred to.ALSO:A moulding powder is produced by heating rapidly a cyclic carbon compound other than coal, e.g., naphthalene, anthracene, phenanthrene, coal tar, or coal tar pitch, in an inert atmosphere, to a temperature which produces intumescence, e.g. 350-550 DEG C., cooling and powdering the product, moulding to desired shape and heating under non-oxidizing conditions, sufficiently rapidly to produce agglutination but not to cause intumescence, to a temperature above 550 DEG C. and preferably above 700 DEG C.
