Title: Apparatus for Pumping Gases.
IPC: F04D29/10
Filed: 1968-06-27
Abstract: 1,180,006. Casings for dynamo electric machines. SULZER BROS. Ltd. 27 June, 1968 [18 Aug., 1967], No. 30776/68. Heading H2A. [Also in Divisions F1 and F2] In gas pumping apparatus comprising a blower 1 which is driven by an electric motor 2 enclosed in a gas-tight housing 3 with the blower, the blower compartment 11 and the motor compartment 12 are separated by a partition 13 and gas leakage between the two compartments is prevented by a liquid seal 14 in the partition, means being provided to collect liquid leakage from the seal into each of the compartments. The blower impeller 7 and motor 6 are on a shaft 8 mounted in bearings 9. Sealing liquid is fed by a pipe 15 to a chamber 16 in the seal 14 and liquid escaping from the seal is collected in grooves 17 and 18 in the blower and motor compartment respectively and drained via ducts 19 and 20 to separators 21 and 22 and extractors 23 and 24. The separated sealing liquid passes to a reservoir 25 and is returned by pump 26 and pipe 33 to the seal 14. The gas from separator 21 is led through pipe 35 to the blower 1 together with gas from extractor 23, the pressure of the latter gas being increased by a compressor 36. Gas from separator 22 is returned to the motor compartment 12 via compressor 27 and lines 28 and 29 and any gas from extractor 24 is drained through a pipe 30; gas losses in compartment 12 being made up from a gas cylinder 31.

Filed: 1956-10-11
Abstract: 828,333. Water-tube steam boilers; superheaters. BABCOCK & WILCOX Ltd. Oct. 11, 1956 [Oct. 11, 1955], No. 30971/56. Addition to 738,092. Classes 123(2) and 123(3) The steam boiler described in the parent Specification is modified in that the downpass 56 and by-pass 58 which are separated by a refractory wall 66 contain an economizer 18 the tubes of which extend through the wall 66. A metallic wall 68 extends downwardly from the bottom of the wall 66 to flow-proportioning dampers 70, 72. From the top of the wall 66 economizer tube portions 64 are inclined upwardly and inwardly to a position in line with and beneath the front row 82 of the tubes of a primary superheater 16 which is located in the chamber 59 forming the rearward extension of the lateral pass 13 from the furnace chamber 10, the tubes 64 then extending horizontally and rearwardly to form a floor 87 beneath the superheater. From the floor the tubes extend upwardly to form a screen 84 behind the superheater. The tube portions 64 and the floor 87 are made gastight with refractory material, the floor serving to prevent any solid matter dislodged from the superheater 16 from falling on the economizer 18. The gas flow through the superheater 16 is controlled by the settings of the dampers 70, 72 to give a constant steam temperature over a wide load range.

Title: A new method of and means for graining painted surfaces
IPC: B27M1/00
Filed: 1935-11-09
Abstract: <PICT:0453253/III/1> A graining-tool comprises two or more rows of springy metal teeth f, g, k of equal length, mounted in staggered relationship in the bevelled end d of a handle l, so that the different rows contact with the surface to be grained progressively in advance of each other.  In a process of graining by means of such tools, the base material is first primed and then has a layer of ground paint applied thereto which is allowed to dry and harden.  A second coat of paint is then applied on which, while still wet, the required pattern is worked by the graining tools.  After drying, a coat of stain or scumble, and a final coat of varnish may be applied. An indented effect is obtained without the base itself being indented.

Abstract: 780,752. Ultrasonic inspection devices. GENERAL ELECTRIC CO. Oct. 27, 1954 [Dec. 31, 1953], No. 31030/54. Class 118 (2). [Also in Group XXXIX] In an arrangement like that described in Specification 714,564 for producing surface waves in an object 10 by projecting longitudinal waves on to the object at an angle of incidence greater than the critical angles for longitudinal and shear waves, a quartz or barium titanate transducer 12 is coupled to the object by two wedges 20, 21. The velocity of longitudinal waves in the wedge 21 must be less than the velocity in the object 10. Preferably the velocity of longitudinal Waves in the wedge 21 is one-half the velocity of such waves in the first wedge 20 and one-half the velocity of shear waves in the object 10. In a modification, Fig. 5, designed to avoid detection of echoes from the totally reflected waves, the transducer 12 is mounted in an opening 23 on a holder 22. The holder is cut away at 22b leaving space for a wedge between the holder and the object. In each embodiment, the second wedge 21 may consist of oil or grease or of thermoplastic material.

Title: Improvements in arrangements for operating shears for rolled stock
IPC: B23D15/14

Abstract: 862,912. Shearing. SIEMAG SIEGENER MASCHINENBAU G.m.b.H. Oct. 2, 1958 [Oct. 4, 1957], No. 31451/58. Class 83 (4). In an arrangement for operating shears for rolled stock having blades and piston drives that run in opposite directions for starting movements of the top and bottom blades, the starting movements for the top blade 4 and the bottom blade 1 are effected by pumps 15, 151 which, after completion of the starting movements, deliver together with pumps 25-30, connected in parallel, the pressure medium for the cutting movement of the shears. On operation of a valve 18 the bottom blade 1 is raised by starting cylinder 7 by an amount determined by a limit switch or stop, the latter actuating a valve 47, electrically or by pressure damming, to divert oil from the pump 151 to the intensifier 38. Similarly the starting movement of the top blade 4 is effected through a valve 14 and starting cylinder 11, while at the same time the pistons 8 displace oil through the valve 14 to a reservoir 46, the top blade being arrested by a limit switch or the workpiece interposed between the blades. After the initial movement of the upper blade, pump 15 and pumps 25-30 deliver oil to the intensifier 38 which operates on water from a reservoir 41 to actuate a cylinder 3 thus to complete the cutting stroke. The lower blade 1 of the shears is connected to the cylinder 3 by members 2.

A device for locating components having a hole therein about a receiving pin is described with reference to the operation of transferring washers 28 from a raceway 1 to a pin 8. A carrier member 25 has a first slot 4 which is open towards the raceway and is also open towards the pin 8 and a second slot 3 which is open towards the pin 8 only. The member 25 is mounted on a block 2, Fig. 1 (not shown), which is reciprocated by a pneumatic cylinder 22 between the position shown in Figs. 1 and 2, and a position in which the axis of the washer is co-incident with the axis of the pin 8. As the block moves forward a pivoted latch 5 engages a lever 7, the end 7a of which is engaged with the end 8a of the pin and lowers the pin. At the end of the forward movement of the block the latch passes over the lever and the pin 8 rises and passes through the washer. The washer is retained in the member 25 as it moves forward by a spring-loaded finger 26. As the block 2 is moved backwards the finger 26 opens and the washer remains on the pin 8. The pivoted latch 5 rotates clockwise against a spring 5b as the block 2 moves backwards and rides ineffectively over the lever 7.

In an after-burner for purifying exhaust gases, the exhaust gases entering at A, Fig. 1, flow around the wall of a combustion chamber BL to heat it before entering it, where they are mixed with additional air and ignited. The gases flow through chambers AK and KE to a chamber K1 around the combustion chamber wall W and then flow through pipes R 2  and openings Z 1 , O 4 , into the combustion chamber BL in which pulsed combustion is stated to occur, the additional air entering through a main orifice O, and additional inlets O 3 . The mixture is ignited by a spark plug ZK and the burnt gases, mixed with further air entering at O 8 , are discharged through outlet S. In Fig. 3, outlet S is cooled by engine cooling air blown through a chamber C, the heated cooling air being used for heating purposes. The outlet S may also discharge into a further combustion chamber. In Fig. 10 (not shown) the exhaust gases are fed to a pair of chambers K1, K2 around the afterburners N1, N2, which afterburners discharge into chambers Al, A2, around the air entry pipes S. In Fig. 12 (not shown), the exhaust gases enter through a pipe A heated by the gases leaving the afterburner, which flow through an annular space V which also serves to silence the gases.
