Title: Improvements in and relating to door-closing and -checking devices
IPC: E05F3/16
Filed: 1923-11-30
Abstract: 220,528. Smith, H. Nov. 30, 1923. Operating and controlling doors by springs and checks.-In a device with a closing spring and a check device in the form of a friction brake, the check consists of a fixed brake-shoe that engages a rotatable drum or other rotary member connected with the door-closing lever and having a brake surface shaped to allow the door to close freely at the end of its closing movement. A second spring may also be provided to assist in the checking movement of the door. The lever connections between the check device and the door provide for the door to be held in the fullyopen position. In the arrangement shown, the closing spring d and an oppositely-wound weaker spring e that serves as a door check are mounted in a cylinder a secured to the door frame. Between the springs is arranged a member b integral with the lever b<3>. This member carries a pair of trunnions b<1>, b<2> that engage sleeves c, c<1> integral with ratchet wheels c<2>, c<3>, and these ratchet wheels are each engaged by resilient arms b<5> on the centrally-positioned member b. The upper ends of the members c, c<1> are mounted in the closure members a<1>, a<2> of the casing and are formed with extensions c<4> for tensioning the springs d, e. The member b is engaged by a brake shoe g<1> attached to the fixed casing a, the surface of the member b being cam-shaped or cut away so that as the door closes the frictional effect gradually or quickly decreases. The brake shoe may be spring-pressed into engagement with the movable brake surface on the member b. The lever b<3> and the lever h connecting it to the door may be suitably proportioned to permit the door to remain in the fullyopened position. For mounting the device, the casing a may be formed with an arcuate plate i which may be fitted to an adapter plate, j secured over the frame moulding. Both of the springs d, e may be arranged on the same side of the member b.

Abstract: 986,266. Compression moulding machines. G. DALL'OGLIO. Aug. 22, 1961 [Aug. 27, 1960], No. 30249/61. Heading B5A. Powdered material is placed on a twopart die 12 by a carriage 13, compressed by a die 11, with light pressure to exclude gases and then compressed with greater pressure to compact the material. The downward movement of the die 11 caused by the motion of a flywheel 7, screw 6 and crossbeam 5 depresses a part 62 of the two-part die 12 connected to a plunger 18 in a barrel of oil 30, so that the part 62 moves slowly until the lower face of the plunger 18 reaches the lower end wall 108 of the barrel 30. When a valve 20 connected to an hydro-pneumatic accumulator 19, closes and stops the movement of the plunger 18 so that the material is compacted. The die part 62 is then raised, the moulded material removed and the cycle repeated. The movement of the plunger 18 and the carriage 13 are co-ordinated by an hydraulic system having two cocks 43, 43<SP>1</SP> (see Figs. 4 and 5, not shown) which are operated to start or stop the cycles. The movement of the carriage 13 can be made to depend on that of the crossbeam 5 by making a roller 142, Fig. 6, which is connected to a plunger 34 of an hydraulic system, follow the profiles 140<SP>1</SP>, 141<SP>1</SP> of two cams 140, 141.

IPC: B01D3/00
Filed: 1958-09-24
Abstract: <PICT:0878193/III/1> In distillation apparatus in which vapour flows from an evaporating vessel to a condensing vessel, the vapour is caused to flow through an auxiliary vessel interposed between the evaporating and condensing vessels, the auxiliary vessel containing distillate and being provided with means for maintaining the distillate at a substantially constant level; the vapour is thus scrubbed by the distillate and freed from entrained droplets of liquid undergoing distillation.  As shown, vapour from evaporating vessel passes up passage 12 to an auxiliary vessel 13 formed with inner and outer walls 15, 16 arranged so that the vapour flows downwardly in the space between the walls, whence it passes into perforated channels 17 which deliver it into condensate contained in the vessel 13.  The level of distillate 14 in the vessel 13 is kept constant by a delivery pump for condensate (not shown) and downcomers 22, which return any excess of distillate to the evaporating vessel. Perforated plates 18, 19 are arranged in the vessel 13 below the level of the distillate, and a corrugated wire-mesh plate 20 is mounted above the distillate.  The scrubbed vapour emerging through the plate 20 passes to the condensation vessel (not shown).
