Title: Apparatus for controlling an elevator
IPC: B66B1/52
Filed: 1971-04-20
Abstract: 1349686 Lift control apparatus HITACHI Ltd 20 April 1971 [20 April 1970] 10090/71 Heading B8L  A lift selector includes a tracing member 6 supporting a projection 10 supporting travelling contacts, driven at a first reduced scale speed, proportional to that of the lift cage, and cooperating with fixed contacts thus determining the proximity of the lift to any target floor. A chain, magnetic tape, or wire 16 carries shielding plates 18 co-operating with grooves 20 on a position detector 19, or a corresponding pattern of magnetization co-operating with magnetic heads, and is driven at a second reduced scale speed, greater than the first, and controls the deceleration of the lift cage. The chain 16 may be endless, or mounted on reels. Operation of lift car (a) More than one floor.-In response to a hall or car call requiring, say, ascent, contacts U-1 to U-4, Figs. 4A, 4B, 9 (not shown), close, and closure of contact 15-1, Fig. 3 (not shown), causes the energization of relays (21-26), in a time dependent sequence controlled by delay relays (22T-26T) to give acceleration in six steps. Upon approach to a target floor, completion of circuits, first via contact (2FU), Figs. 2, 4A (not shown), then via contact (1FU) causes the energization of self held relays (2F, 1F), Figs. 4A, 3, 5 (not shown), initiating distance dependent deceleration. The passage of the plates 18 through the grooves 20, see also, Figs. 7, 8 (not shown), causes the detectors (26MU-21MU), Fig. 9 (not shown), to provide firing pulses to thyristors (26TH- 21TH), Fig. 5 (not shown), energizing relays (265-215), and thus, via contacts (265-1- 215-1), Fig. 3 (not shown), de-energizing sequentially relays (26-21), giving six stages of deceleration. (b) One floor.-The proximity of the lift to the target floor means that relay (2F) is not operated, so that the opening of contacts 1F- 3F, Fig. 3 (not shown), renders relays (25, 26) inactive. Thus only four stages of acceleration, and correspondingly deceleration are used. The plates 18 are mounted either singly or in transverse groups along the chain 16, see Figs. 8, 7 (not shown), and interrupt the coupling between a pair of induction coils to provide the detector outputs. Separate sets of contacts, grooves and detectors are provided for ascent and descent respectively.

Title: Gas Combustion Apparatus
IPC: F23D14/02
Filed: 1967-03-06
Abstract: 1,179,023. Gas turbine and like combustion chambers. WINGAERSHEEK TURBINE CO. INC. March 6, 1967 [March 17, 1966], No.10414/67. Heading F1L. [Also in Division F4] A gas combustion apparatus has a vortex generator at the inlet to a combustion chamber to set up a swirl and an eddying wake in the combustible gaseous mixture entering the chamber, the vortex generator being arranged so that combustion of the gases immediately adjacent the wall of the combustion chamber is delayed until near the outlet of the chamber. The combustion apparatus in one form comprises, Fig.1 a cylindrical mixing chamber 3 to which air is supplied by a compressor 1 via a valve 5 and fuel gas via a duct 7 and valve 9. The air/fuel mixture passes from the chamber 3 through a flame-holder 11 into a combustion chamber 13 where it is ignited by a spark plug 15 energized from a spark generator 17, the combustion gases flowing, for example, to a turbine or furnace. The flame-holder 11 comprises a hub portion 21 carrying at least two helical swirl vanes 23, 25 which set up a vortex in the combustion chamber 13 so that the cooler, denser particles of the mixture are centrifuged outwards to tend to cool the chamber wall, combustion of the gases adjacent the wall not taking place until near the chamber outlet. The vanes 23, 25 may be hollow or solid and have blunt trailing edges, Fig. 5, which cause eddies in the mixture to improve combustion stability. A fuel nozzle may be mounted on the hub 21. The dimensions A and B are substantially equal. In a modification, Fig.7, the combustion chamber is of rectangular cross-section and is supplied with air/fuel gas mixture from a mixing chamber through two rectangular section inlet ducts defined respectively by curved walls 41, 45 and 43, 51. The curvature of the inlet ducts sets up a vortex in the combustion chamber and the upstream wall 39 induces an eddying wake adjacent thereto. A similar arrangement is illustrated in Figs.9, 10 (not shown). In a further modification, the flameholder comprises a set of passages defined by helically wound tubes with the spaces between the tubes blocked to provide stabilizing regions.

Title: Method and apparatus for friction welding thermoplastic components
IPC: B29C65/06
Filed: 1965-03-11
Abstract: 1,058,534. Seaming non-metallic sheet material. GEORG FISCHER A.G. March 11, 1965 [March 12, 1964], No. 10455/65. Heading B5K. [Also in Division F2] In a method of friction welding two surfaces together, one of which is rotated relative to the other, the bearing pressure on the surfaces during the relative rotation is so controlled that the driving power employed and thus the heat capacity remain approximately constant and the bearing pressure on the surfaces is increased on stopping the rotation. In one embodiment, Fig. 1, to seal a cover 31 to a tube 32 torque is transmitted to the cover 31 by a spur gearing 34, peripheral teeth or a toothed pin through a member 35 arranged on a steep thread 39 of a driving spindle 36. A spring 38 urges the member 35 into contact with the cover 31. A shoulder 33 permits the cover 31 to be centred on the tube 32. As welding proceeds the coefficient of friction between the cover 31 and the tube 32 increases and the member 35 is lifted upwardly against the action of the spring 38. When rotation is stopped, the full bearing pressure of the spring 38 becomes operative to ensure a good weld. In a second embodiment, Fig. 2 (not shown), in which flanges 43, 44 of parts 41, 42 are welded together, the part 42 is driven by bevel gearing 46 from a driving bell 47 driven by the conical armature 48 of a displaceable armature motor 50. A compression spring 51 adjustable by a screw 52 urges the bell 47 downwardly. With increasing torque due to increasing coefficient of friction, the armature 48 is pulled up magnetically against the spring 51 to reduce the torque and relieve the seam from pressure. The seam may be flat or conical. In a third embodiment, Figs. 3 and 4 (both riot shown), tubes 1, 2 are welded together with an intermediate element 6 provided with peripheral teeth 3 engaging those of a gear-wheel 10 on a driving shaft 18. The tubes 1, 2 are forced axially towards each other by clips 11, 12 and a tensioning clamp comprising levers 13, 14, a spring 15 and a tie-rod 16. The shaft 18 includes a coupling 19 having teeth 17 and increasing torque causes the gear 10 to be lifted so that the force between the tubes 1, 2 is reduced. When the shaft 18 is stopped the full force of the spring 15 becomes effective to produce a good weld.

Title: Improvements in the stabilisation of organic esters of cellulose
IPC: C08B3/28
Filed: 1944-06-02
Abstract: Organic acid esters of cellulose, e.g. cellulose acetate, propionate, butyrate, aceto-propionate and aceto-butyrate, are stabilised by subjecting them to the action of an aqueous solution of sulphuric acid containing a small proportion, based on the weight of the solution, of a wetting agent which is stable in the acid solution, while they are in suspension in said solution. Preferred wetting agents are the sodium salts of the sulphates of long chain secondary or branched chain alcohols, particularly the sulphates of 3 : 9-diethyl-6-tridecanol, 7-ethyl-2-methyl - 4 - undecanol and 2 - ethyl - 1 - hexanol.  Other suitable wetting agents are turkey red oil, the sodium salts of alkyl benzene sulphonates in which the alkyl chain contains from 12 to 18 carbon atoms and the sodium salts of monobutyl-phenyl-phenol monosulphonate and dibutyl - phenyl - phenol disulphonate.  The stabilising treatment may be effected at temperatures of from 18 DEG  to 100 DEG  C.  Examples are given, in one of which acetone-soluble-cellulose acetate is suspended in an aqueous bath containing 0.1 per cent sulphuric acid and 0.05 per cent of the sodium salt of 3 , 9-diethyl-6-tridecanol sulphate, and stabilised by treatment therein for 4 hours at 22 DEG  C.  In another example, the stabilising bath contains 10 per cent of sulphuric acid and 0.08 per cent of the sodium salt of 2-ethyl-1-hexanol sulphate, cellulose acetate being suspended therein for 10 minutes at 100 DEG C.
