Title: Improvements relating to wood moulding machines
IPC: B27M3/24
Filed: 1947-10-23
Abstract: 639,068. Wood moulding machines. NESBIT, A., CARTER, H. C., and CARR, E. Oct. 23, 1947, No. 28339. [Class 145(i)] In a wood moulding machine used for profiling, e.g. brush backs, blanks are stacked in a magazine a, withdrawn individually by lugs c on a conveyer chain b and transferred to a second conveyer d having spikes e on which the blanks are impaled by pressure rollers f and presented successively to rotary cutters g, h pivotally mounted, as at k, for finishing the sides and ends of the blanks, means being provided for controlling the movements of the cutters to give the desired contour to the sides and ends of the blanks. The means referred to comprise preferably revolving cams s coupled with the cutters by levers q and links r to swing the cutters and their driving motors i bodily about their pivots k against the restraint of weights m. The conveyer is driven by a motor v through a two-speed gear w actuated by a lever 2 pivoted at 3 and having a roller 4 running on the edge of one of the cams s (Fig. 3, not shown), so that the conveyer is slowed down to enable the cutter before and after working over the side of a blank to move inwards and work over the end before the blank moves on, and so that the conveyer runs at full speed at other times. At the feed end of the machine the shaft z geared to the shaft y of the conveyer d to drive the conveyer b, carries a cam 13 which actuates a lever 15 and plunger 17 to push each blank into correct location before being withdrawn from the magazine, whilst at the delivery end an inclined plate 21 raises the blanks from the spikes e. The tops of the pivot pillars k are connected by a link p for added support.

Abstract: 1,133,607. Retractive switches. DUCTILE STEELS Ltd. 26 June, 1967 [24 June, 1966], No. 28360/66. Heading H1N. A pendant control device comprises a plurality of push-button control switches and an over-riding safety switch so arranged that the safety switch and any selected control switch can be operated simultaneously using only one hand. A casing 10 comprising metal or plastic rectangularsection portions 11, 12, 13, 14 secured together by rubber grommets 15 houses a number of control switches 31. Each switch 31 is operable by a respective button 35 urged outwardly by a rubber mounting which also acts as a seal. Movable bridging contacts 34 are urged outwardly by springs not shown. A safety switch 40, which may be connected in series with a common return lead for the switches 31, comprises a bridging contact 47 operable by a plunger 41 engaged by a plate 50 which is pivoted on a pin 53 between lugs 21 on the top casing portion 13. Lugs 21 serve for attachment of a suspension chain or cable 22, and corresponding lugs 55 on bottom casing portion 14 carry a pin 54 which limits outward lever movement of plate 50. In an alternative embodiment (not illustrated) the switch 40 may be situated on the same side of casing 10 as switches 31, in which case the plate 50 overlies buttons 35 which are actuated via apertures in the plate 50 and the operator's thumb or finger simultaneously depresses plate 50 by engaging the edge of the aperture around the selected button 35. In another embodiment the switch 40 is mounted in an end wall of the casing 10 and plate 50 is pivoted on the said end wall and bent to extend over the vertical side of the casing, either opposite to or on the same side as buttons 35. In yet another embodiment the switches 31 may be mounted on a carrier plate which is movable against spring means to actuate the safety switch 40.

Title: Production of gases containing sulphur dioxide
Inventor: WITTMANN GEORG
IPC: C01B17/52
Filed: 1959-08-21
Abstract: A process for the production of gases containing sulphur dioxide together with the recovery of roasted residues practically free from arsenic and/or antimony and particularly lead. by the stepwise roasting of sulphidic ores containing arsenic and/or antimony and lead with free oxygen containing gases is effected in three successive fluidised layers, about one-third of the total amount of oxygen required for complete reaction with the sulphidic ores being supplied separately to each individual layer and the roaster gases being removed independently and separately from each layer, the temperature of the first layer being 550-800 DEG C. of the second layer more than 800 to 1000 DEG C., and of the third layer 550-800 DEG C.  The temperature of the 1st layer is preferably 550-600 DEG C. and that of the 2nd layer 650-750 DEG C.  The sulphidic ore may pass in succession through the fluidised layers under the influence of gravity.  Flue dust contained in the roaster gases leaving any fluidised layer may be collected in a cyclone associated therewith and maintained at about the same temperature and passed hot together with the coarse, partially roasted ore to the next layer, the partially roasted ore preferably being introduced into the next layer through the dust outlet of the associated cyclone.  By means of cooling surfaces within the individual layers, reaction heat beyond that required for maintenance of reaction temperature and to cover heat lost by radiation, together if desired with the sensible heat of the products of roasting, particularly that of the roaster gases, may be used in the production of hot water and/or steam. Specification 811,859 is referred to.

Divided out of and addition to 456,285 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 4, 1935. [Class 81 (ii)] The invention relates to a surgical suturing-appliance including a pincette, in which the interior of the casing forms a magazine for a pile of gripping members, the lowermost gripping member having retained by the action of a pair of resilient or pivoted rigid limbs which are also utilized to apply the lowermost gripping member to the skin. According to the invention each limb 23, 24 has an arm 28 or 29 formed with a Z-shaped slot 30 engaged by a pin or screw 32 secured to the casing 18. The arms are biassed upwardly by a spring 34 so that the lower portions of the slots are engaged by the screw 32. A spring-pressed block 36, which urges the gripping members downwardly, is provided with a pin on which is mounted a pawl 41 having a tooth 42 engaging a rack 43 formed on one of the edges of a longitudinal slot formed in the casing 18. When the appliance is to be recharged, the pawl is moved so that it coacts with a widened portion 21 at the top of the slot to retain the block in an upper position and a lug 48 on the arm 28 is moved upwardly so that the limbs 23, 24 are moved outwardly by the engagement of the screw 32 with the upper portions of the slots 30.

Title: Improvements in automatic selectivity control for radio receivers
IPC: H03G5/26
Filed: 1937-10-22
Abstract: 489,256. Automatic selectivity control. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 22, 1937, No. 28894. Convention date, Oct. 22, 1936. [Class 40 (v)] Means responsive to signal strength are provided in a radio receiver to vary the effective resistance of one of a plurality of coupled tuned circuits and also to vary the effective coupling, so that the selectivity of the receiver is inversely proportional to signal strength. As shown, a transformer 27 with tuned primary and secondary windings couples an I.F. amplifier valve 9 to the detector 16 and to a phase shifting network 37, comprising condenser 38, resistance 39, and inductance 40 connected in series. An auxiliary grid 25 of valve 9 is connected over lead 43 to the junction of condenser 38 and resistance 39, being biassed by a source 41. The feed-back voltage applied to the grid 25 is displaced in phase by 90‹ relative to the signal voltage on the control grid 21 and its effect in varying the apparent coupling between the primary and secondary of transformer 27 is controlled by the amplification of valve 9 which is dependent upon the A.V.C. bias applied to its control grid 21 over the lead 15. The effective resistance of the transformer primary is also varied automatically by including in the lead 43 a winding 44 coupled to the transformer 27 which feeds back to the grid 25 voltages 180‹ phase displaced from the anode voltage. In other embodiments a separate control valve is provided, A.V.C. potentials being supplied to the single control grid. The phase shifting network may be connected to the primary of the controlled transformer. Reference has been directed by the Comptroller to Specification 459,209.
