Title: Improvements in apparatus for handling, transferring and storing removable load-containers
IPC: B66C17/20
Filed: 1937-01-23
Abstract: 467,802. Handling removable loadcontainers. TENNANT, W. J. (Motor Terminals Co.) Jan. 23, 1937, No. 2085. [Class 73 (iv)] Removable load-containers are run on lorries into the loading and unloading bays formed between the supports 10 and the containers raised by the travelling crane C so that the lorries can be removed, following which any set of four supports 20 can be turned by hand to project at rightangles to its particular bay and the container moved over and deposited on it for storage. The pair of supports 20 on each side of the bay preferably are linked to move in unison. Fig. 3 shows one construction of support comprising two members 20 independently operable to serve adjacent bays. In each case the horizontal run 20a of the support carries the load while the inclined portion 20b forms a strut. The right-hand support is secured to the rotatable cap 26 supported on the collar 22, while the left-hand one is secured to the sleeve 35 supported on the collar 21. The struts 20b are each connected to a separate collar rotatable on the standard. In a modified form brackets fixed to the standard carry vertical pivot pins round which the members 20a, 20b rotate. Means may be provided for fixing the supports in the acting or the retracted position, or one pair of supports for one end of the container may coact with a fixed platform to support the other end. In some cases the load on the entering vehicle may contact with the supports and turn them automatically into the retracted position.

Title: Method and device for controlling continuously operating distilling apparatus
IPC: C10G7/12
Filed: 1938-01-22
Abstract: In a continuously operating still, e.g. for oil, the distillation conditions are controlled in accordance with variations in a characteristic of one of the distillates, such characteristic being determined by a test distillation of such distillate at a temperature intermediate between its initial and final boiling points, e.g. at the 50 per cent distillation point. In a column still 1 the amount of reflux circulated by a pump 9 is regulated by a valve 11 controlled by a thermostat 10 dependent on the head temperature of the still.  A part of the head product is led off continuously by a pipe 19 to a condenser 20 and receiver 21 under constant pressure provided by a line 42.  Water drains out at 23 and excess condensate by the overflow pipe 22, so that there is a continuous and steady flow of condensate, as indicated by a meter 41, to the test column 12, which is heated by resistances 13, 14, 15, 16, adjustably controlled by a thermostat 18 so as to keep constant the temperature of the vapours given off by the residual liquid at <PICT:0496168/III/1> the bottom of the flask.  The distillation is effected under constant pressure controlled by a regulator 26.  Under these conditions one half of the head product should distil over into the receiver 25, and one half remain in the distilling flask. Such residual liquid flows out through a pipe 30 and condenser 31 through siphons 35, 36, to a calibrated exit orifice 34.  Any variation in rate of accumulation of the residue raises or lowers the float 37 and actuates the flow-meter indicator 40 which in turn controls the operating point of the thermostat 10.  A similar apparatus may be used at the same time to indicate continuously the final distillation temperature or the 95 per cent point.

Title: Improvements in or relating to variable pole windings for alternating current dynamo-electric machines
IPC: H02K17/14
Filed: 1926-01-26
Abstract: 268,909. Siemens - Schuckertwerke Ges., and Weinert, H. Jan. 26, 1926, Alternating-current motors; dynamos, regulating; motors, controlling.-In an alternating- current winding adapted for use as a normally connected 8 n-pole 3-phase grouping or as a 6 n-pole 2-phase grouping in T-connection energized from a 3-phase supply, the ratio of the effective number of series-connected winding elements in the vertical member of the T to that in the horizontal member is made less than unity by means of parallel or series-parallel connection of the elements. Fig. 6 shows the 8 n-pole connection in delta of the twelve consecutively numbered winding elements of normal type shown in Fig. 1, the supply being at the points R, S, T. For the T connection the elements are grouped as -in Fig. 5 with two parallels, each comprising three series coils in the vertical limb and a series-parallel connection in the horizontal limb so that the above-named ratio is 3:4. Other T-groupings giving a ratio less than unity are described in the Specification. The elements 2, -8 in Fig. 5 carry greater currents than the paralleled elements 6, 10 and -4, -12 and a balanced current loading may be obtained by altering the numbers of turns or cross-sections of some elements or hv the use of resistances in parallel therewith. An alternative arrangement for current equalization is shown in Fig. 1- wherein each half of the horizontal T member consists of two series-connected coils, such as 6, 10, in parallel with a coil 2 having twice the number of turns in the coils 6, 10 or half of their cross-section. For pole numbers 4n or 8n the two portions 2, -8 may each be subdivided into halves connected in parallel so that both portions will have as manv coils connected in series and with the same current loading as the remaining portions. The range of synchronous speeds, for example 750 and 1,000 revs. per min., given by the delta and T-groupings mav be extended to 1,500 by regrouping from the T arrangement to double star grouping Fig. 7, of known form.

Title: Blasthead structure,particularly for tempering glass sheets
IPC: C03B27/052
Filed: 1965-01-20
Abstract: A blasthead structure for thermally tempering glass sheets comprises a pair of horizontally opposed blastheads 27, 271, Fig. 2 (not shown), each blasthead comprising walls partly defining a pressure compartment which is open towards a substantially similar compartment of the other blasthead, and means for introducing a gas to the compartments at substantially equal rates of flow, wherein the walls are arranged to extend towards a glass sheet suspended therebetween to within a predetermined and uniform distance of the surfaces of said sheet so as to leave a clearance space 63, Fig. 6 (not shown), between the walls and the surfaces whereby escape of the gas is substantially restricted to the clearance space 63 and the pressure so created in the pressure compartments causes automatic centring of the sheet between the blastheads, means 51, Fig. 5 (not shown), being provided on the outer side of the compartment walls for the exit of the gas.  The blastheads are each divided into four compartments 49 and two end compartments 52, 53, Fig. 3 (not shown), by a series of walls extending across their width and depth.  Within these compartments nozzles 61 are arranged in a regular square lattice pattern, of six horizontal rows in compartments 49 and half as many again in the end compartments 52, 53.  The nozzles of the centre four rows are each joined to the nozzle below by a vertical web 64, Fig. 5, with halfwebs extending from the last two nozzles, whilst the end two rows are joined by a horizontal web 62 thus providing sub-compartments. Between each compartment 49, 52, 53 is provided an exhaust area 51, but within which are placed blast nozzles 70 (Fig. 6).  The nozzles of one blasthead are located directly opposite to the nozzles of the other blasthead.  The blastheads are slidingly connected to air ducts which have valves therein all operated by a single pneumatic cylinder 48, Fig. 1 (not shown). The blastheads are mounted for oscillatory motion and have a surface contour similar to that of the glass sheet to be tempered.  Preferably the blasthead apparatus is mounted immediately below a furnace for heating glass sheets.  A glass sheet suspended freely from its upper edge is heated in the furnace and then lowered to between the blastheads.  The construction of the pressure compartments is such that if the sheet moves towards one blasthead, pressure builds up very quickly in its pressure compartments and decreases rapidly in those of the other blasthead, the sheet thus being quickly centred.  The cooled tempered sheet is finally removed.
