Title: Improvements in or relating to space heaters
Inventor: WOLLNER PAUL
IPC: F24H3/04
Filed: 1970-11-19
Abstract: 1286187 Space heaters AEROIL PRODUCTS CO Inc 19 Nov 1970 55141/70 Headings F4S and F4W In a portable space heater comprising a cylindrical combustion chamber 24 surrounded by a vertical duct 26 to define therebetween an annular passage through which air to be heated passes, the hot combustion gases exit through a perforated cylindrical screen member 33 which becomes incandescent and serves as a source of radiant heat. A protective grille 34 surrounds the screen member. At the top of duct 26 is a grille 28 above which is a horizontal baffle 30 arranged to deflect the heated rising air leaving the annular passage outwardly and downwardly into the space to be heated. Both the bottom of the annular air passage and the combustion chamber communicate with a horizontal duct 20 which is supplied with air by a fan 22. Radial vanes 23a give the air entering the combustion chamber 24 a turbulent motion. The chamber is fired by an oil burner 25 ignited by electrodes 29. Fuel for the burner is stored in a tank 27. In a modified embodiment (Fig. 5 not shown) a Venturi tube (40) serving as a mixing chamber is disposed over a fuel nozzle (42) within the horizontal air duct (20); the top of the tube communicates with the combustion chamber.

Patent GB-1254146-A (GB)
Title: Card transport or feeding mechanism
IPC: G06K13/063
Filed: 1969-11-14
Abstract: 1,254,146. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORP. 14 Nov., 1969 [23 Dec., 1968], No. 55773/69. Heading B8R. A card-feeding apparatus comprises a front registering stop and a member which engages the trailing edge of the card to prevent rebound of the card from the front stop. As shown, cards are fed one by one from a spring-supported pile 11 by a continuously-rotating and intermittently raised and lowered roller 19. Rolls 28, 29 with a small gap between them, and the lower one 29 of which is continuously driven, move a separated card over a table 21 into a gap 41 between a ferrous stripper plate 37 and a punch die plate 38 until the front edge of the card abuts against a front stop 46. As the card moves on to the table 21 it rotates a member 30 in a clockwise direction about a pivot 32 against the action of a spring. The member 30 has eccentric edges 30b which, when the rear edge of the card passes the member, rotate anticlockwise under spring action to engage the card rear edge to prevent rebound of the card from the stop 46 and hold the card against the stop. The bottom surface 46a of the stop 46 is normally pressed lightly against the plate 37 by a leaf-spring 45, Fig. 4, connecting a stopcarrying arm 44 to a fixed support 43. However, a coil 50 in the stop 46 can be energized as referred to later, so that in conjunction with the ferrous plate 37, the stop 46 is held tightly by magnetic action against the plate 37. A chamfered part 46b on the stop 46 constitutes the aligning edge. Two rollers 52, 53 are situated to one side of the stop 46, the roller 53 being intermittently driven in fractional parts of a revolution and the roller 52 being freely rotatable and intermittently moved towards and away from the roller 53. In operation, at the time a card reaches the stop 46, the coil 50 is energized to press the stop downwardly, the roller 52 being raised. The roller 52 is now, lowered with the roller 53 stationary, and the coil 50 is de-energized. On the next incremental movement of the roller 53 the card is fed a short distance forward, its leading edge lifting and passing beneath the stop 46. Whilst the rollers 52, 53 are stationary, punch rods 36 are operated to perforate the card in a first column. Subsequent incremental movements of the roller 53 feed the card forward in steps for the punching of further columns, and finally move the card out of the apparatus, whereupon another card is fed from the pile 11 and the operations are repeated. If there is a malfunction of the machine whilst the roller 52 is in driving engagement with the roller 53, the engagement of the card leading edge with the chamfered part 46b raises the stop 46 to allow the passage of the card without damage thereto.  Lateral registration of the card is effected on the table 21 by means of two side guides, one (22, Fig. 1) being fixed and the other (25, Fig. 3) being urged by a light spring towards the fixed guide.

Abstract: 575,016. Ignition systems. BRITISH THOMSON-HOUSTON CO., Ltd., COE, R. T., ROBINSON, T. F. and WELCH, D. F. Feb. 8, 1944, No. 2361. [Class 7 (iv)] An electrical ignition system for an internalcombustion engine has a separate transformer B connected to a low voltage magneto winding L1a through a condenser CS which is shunted by a damping resistance RS for the purpose of reducing the after current which follows the main oscillating discharge. In Fig. 1 the transformer secondary is connected to a distributer D and thence to spark plugs S1, S2, through leads having capacities to earth of C2. The usual contact breaker is shunted by a condenser C1. The condenser CS has a value sufficient to offer appreciable impedance to after current at spark repetition frequency and the damping resistances are equal to where L1a and L1b are in henrys and CS in farads. The invention is preferably used in conjunction with the circuit described in Specification 545,857 in which a peaky wave form of secondary open circuit voltage is obtained. In a modification, Fig. 2, the invention is applied to a system having low tension distribution with separate transformers B1. B2, &c. in the leads to the plugs.

A parison 81 is continuously extruded into the closed moulds which move at a corresponding speed, and close the parison by welding its lower end. Blowing tube 69 moves downwardly with the moulds and returns after it has blown one container. Filling material is then supplied through tube 70, mould parts 13, 13a are closed and the neck-portion then blowmoulded. The left-hand blow mould halves contain a peg 95 extending into the container base to retain the moulded container, assisted by offset roller 96. The container then falls down shoot 98 or is stripped by resilient-bladed stripper 101 on to conveyer 106. On movement along conveyer 106, Fig. 2, the containers are stopped by U-shaped stop-bar 114 until pusher bar 132 is retracted by cylinder 131. They are then allowed to move on to U-shaped stop-bar 113 and moved on to tracks 151 by bar 132. Rejects are fed past stop-bar 113 along the conveyer 106.

[Also in Division B2] Stratified sheets or plates of synthetic resin having a glossy or dull appearance are produced by subjecting one face of a support to a preliminary polishing, partially frosting the polished face, spraying an un-hardened hardenable synthetic resin on to the frosted face, applying a decorative material on to the resin layer, applying successive coats of reinforcement that are impregnated with an unhardened hardenable synthetic resin and hardening the resin before withdrawing the stratified assembly from its support. In the Figure a rigid support 1 which can be made of glass, metal, synthetic resin, has its working face 2 polished, and then frosted for example if made of glass by etching with acid or if of metal or synthetic resin by sandblasting. Hardenable polyester resin is then applied by spraying. A porous decorative element 3 of porous paper or felt which has been printed say, to imitate a kind of wood, is applied to the coating and then impregnated with the polyester resin preferably by spraying. Reinforcements are then placed in position and are either impregnated on the spot or impregnated with resin beforehand. These reinforcements can consist of one or more layers of glass fabric 4 or glass fibre or other material 5. The resins are then hardened by applying pressure on the stratified article and at the same time heating before removing the stratified material from the support. The resulting article has a dull or glossy appearance according to the state of roughness of the surface 2. The support 1 may have a curved face 2 in which case curved elements are obtained. The decorative material may be a further resin layer charged with pigment.
