Abstract: 843,294. Diesel-acting two-stroke engines. DORNFELD, R., and DORNFELD, E., [trading as DELMAG-MASCHINENFABRIK R. DORNFELD]. Jan. 31, 1958 [Feb. 8, 1957], No. 3342/58. Class 7(2). [Also in Group XXVI] In a diesel ram cooling air is supplied from the chamber 119 below the piston to cooling passages 112 in the cylinder head and/or conduits 124 in the piston. The ram cylinder 11 is provided with cooling ribs 111 and the piston controls a combined exhaust and scavenging air port 114 arranged so that when it is uncovered on the down stroke of the cylinder cooling air flowing therethrough into chamber 119 is directed towards the bottom of the piston. The cooling spaces 124 in the piston are open to chamber 119 and connected to atmosphere through passages 125, 126 in the piston rod. Cooling air is delivered to the space 112 in the cylinder head and thence to atmosphere through a passage 113, cooling fins 163 on the cylinder head forming a flow restriction therein. The motion of the ram cylinder causes cooling air to be alternately forced out from chamber 119 to atmosphere through the passages 125, 113 and sucked back in therethrough. The fuel tank 13 and injection pump 15 are mounted in the cylinder head.

Abstract: 1421855 Injection moulding TOKO Inc 23 Jan 1973 3434/73 Heading B5A In a method of packaging an electronic component, e.g. a pulse transformer element 1, the component is inserted into a lower mould 6 with its terminal pins 5 inserted in elongated slots 6g, a heated upper mould 7 engaged with the lower mould and thermosetting material injected into the upper mould cavity 7a, whereby the terminal pins 5 are kept free of moulding material. The electronic component 1 includes a thermosetting base member having a flange portion 4b which rests on stepped portions 6f in the lower mould. The top of the flange portion 4b is raised slightly above the level of the lower mould, so that when the heated upper mould descends it softens the flange portion 4b and produces a sealing effect. As shown in Fig. 4 the lower mould 6 comprises a main body 6a and a side plate 6b, the main body including a plurality of cavities 6e. The parts 6a, 6b are held together by screws 6c but biased apart by springs (6d) Fig. 2B (not shown). Two moulds 6 are mounted in recesses 8a in a member 8 together with push members 8c. Obliquely extending projections 8f on the members 8c engage with oblique guide grooves 8e in the sides of the recesses 8a. As a result, when the upper mould is brought down the push members move laterally as well as downwardly and move the side plates 6b into tight contact with the main bodies 6a. A preheated quantity of moulding material, e.g. a phenolic or epoxy resin is inserted into an inlet port (7b) Fig. 3 (not shown), compressed against a circular recess 8d<SP>1</SP> by means of a plunger (not shown) and melted so as to be injected into the mould cavities through runners (7c), 8d and gates (7d).

Title: Improvements in or relating to apparatus for opening and closing doors

IPC: E05F15/10
Filed: 1954-02-08
Abstract: 754,452. Door-operating apparatus. NATIONAL PNEUMATIC CO., Inc. Feb. 8, 1954, No. 3626/54. Drawings to Specification. Class 65 (1). [Also in Group XXXVII] In a system for operating doors, particularly of public vehicles, by an electric motor, undesired movement of the doors from the open or closed position is prevented by an electrically-controlled brake which is controlled by a door-actuated switch and is energized only when the door is in one or other extreme position. In the system described, a second dooractuated switch energizes the brake when the doors are closed ; a resistance is connected in parallel with the motor by a third door-actuated switch when the door is nearly open, to reduce its speed, and a second resistance is connected in series with the motor during the whole of the closing movement so that this movement is slower than the opening. The motor circuits are controlled through relays by a hand selecting switch and limit switches. The motor drives, through spur and worm gearing, a shaft placed in the centre of the door lintel or sill, this shaft having opposed arms linked to arms on two vertical shafts placed at the sides of the doorway and carrying folding doors. In a system for controlling two sets of doors, a rotary switch is used, providing for one set to be opened when the switch is moved in one direction from a neutral (doors closed) position and the other set by opposite movement of the switch ; continued movement in either direction opens both sets of doors. When only one set is open, only the brake of that set is energized. Selective closing is not provided for.

Title: Utilisation of spent digestion liquors obtained in cellulose production
Inventor: GERHOLD MAX
IPC: D21C11/12
Filed: 1961-02-03
Abstract: Organic compounds present in spent digestion liquors obtained in the production of cellulose from cellulosic materials are partially oxidized <PICT:0922774/III/1> together with a combustible gas and the inorganic compounds, e.g. Na2CO3 with NaCl and NaOH, present in the gas produced are recovered by washing with water and are used to prepare fresh digestion liquor which may be recycled to the digestion vessel together with a proportion of spent liquor, while the washed gas is used as a fuel.  The organic compounds may be lignins and the cellulosic material may be wood, straw or bagasse.  In Fig. 1, beechwood is comminuted in 1, fed to digestion vessel 2 where the lignin is dissolved with a liquor containing Na2CO3. The treated cellulose is is fed to 3 where it is washed with water.  From 2 the spent digestion liquor is fed to vacuum evaporator 4 where it is concentrated to at least 50% solids and then may be fed to burner 5 as well as gas reaction chamber 6 at at least 700 DEG C., where it is injected in a finely divided state through nozzles.  Burner 5 is fed with fuel oil and air.  The gases from 6 are cooled and washed in 7 supplied with cooling water from plant 3 and the aqueous solution is fed to a causticizer 10, filter 11 and back to 2.  A part of the cooling water from 7 may be recycled via a heat exchanger 12.  While the gas leaves 7 for a cooling condenser 8 and steam boiler 9.  The burner fuel may be gaseous or liquid hydrocarbons with sufficient O2 and/or air and/or steam to give a producer gas having a calorific value 1,000-3,000 Kcal./cm. and to make the oxidation reaction exothermal.  The weight ratio air:hydrocarbon:spent liquor may be 3,0-6,0:1,0-2,0:0,2-1,0.  The steam used for the oxidation may be derived from the concentration of the spent liquor to less than 50% water, 50-70% solids. 0,1-3,0% Ca compounds, e.g. Ca(OH)2, CaCO3, may be added to the spent liquor to facilitate the oxidation or reduce carbon deposition.  CaO may be added to the gas wash water, to precipitate silicates, and further inorganic cellulose solubilizing agents may be added to the wash water prior to use as fresh digestion liquor.
