Title: Heat Pump Module for Locating in a Loft
Inventor: SMITH JUSTIN
IPC: F24F1/00
Filed: 2009-09-17
Abstract: A heat pump module 10 for locating in a loft has a housing (1 fig 1) and a heat exchanger located in the housing. The housing can be narrower at the top than at the bottom, and can be located proximate to an apex 21 of a pitched roof. The heat exchanger may be two evaporators 31, 32 which may collect heat from ambient air drawn into the housing. Refrigerant flowing through the evaporators may transfer heat to water circulating in pipes associated with the heat pump condenser coil. The heat pump may be suspended from the roof, and may be located in a plenum chamber (24 fig 3). The heat pump module may include one or more fans (38 fig 2) located in the housing, and the housing may also include vents (16, 17 fig 2) through which air can be drawn and expelled. The heat pump module may be located in the top region of a loft where the loft air is normally hottest, and thus improve the performance of the heat pump cycle.

Title: Improvements in and relating to process and apparatus for refining benzene
Inventor: HALDEN CLAUDE ABDER
IPC: C07C7/14
Filed: 1961-03-21
Abstract: Benzene is purified by solidifying by cooling, heating to melt the outer layer or layers of the solid particles and draining away the molten benzene containing impurities and recovering the remaining solid benzene when the desired purity is obtained. Benzene may be extracted from the molten impure benzene and recycled.  The process removes especially saturated hydrocarbons and some thiophene, and may be combined with known methods for removing thiophene; hydrorefining should be effected before the process.

Abstract: 635,207. Boxes. PERAULT, J. April 2, 1946, No. 10193. Convention date, Nov. 17, 1945. [Class 18] A box is formed by folding up the edges of a blank to form a tray, corner flaps d, e being folded on adjacent sides of each corner, the upper edges of the flaps d, e being cut to lie flush with the upper edges of the sides. Extensions m, n of the sides may be folded over to enclose part of the corner pieces, the extensions and corner pieces being secured to the box sides. The box may have inwardly or outwardly sloping sides. An apparatus for forming the box comprises a die 2 which presses the blank into a matrix 8 by descending in contact with a piston 12. As the blank descends towards the matrix 8, the corner flaps d, e are formed by spring-loaded rollers 5, 52, 7 applied in turn and the box sides are flattened against the die by spring-loaded plain rollers 21, 22. The extensions m, n are turned down by a cap 9 which passes over the upper end of the die 2. In making boxes with inwardly sloping sides the matrix 8 has horizontally movable portions which press the blank against the die. The die is made in sections to enable it to be removed from the formed box.

Abstract: 1305761 Valves AMERICAN AIR FILTER CO Inc 4 March 1970 [4 March 1969] 10460/70 Heading F2V [Also in Division F4] A damper arrangement, for use in a unit ventilator wherein fresh air together with recirculated air are admixed, treated and passed through an outlet 6 into the space to be served, comprises a damper plate 13 movable to a selected operative position by rotation of a sleeve 26 via an arm 19 and damper operator 12 which can be actuated in response to selected conditions, e.g. change in temperature of served space. The sleeve which is free to turn on a shaft 15 to which the damper plate is secured has brackets 27, 29 carrying projecting arms 28, 31. A spring 32 connects the damper with the arm 31 so that the damper can rotate independently of the sleeve 26 within limits determined by the characteristics of the spring 32. Since the shaft 15 is located off-centre a sudden gust of wind acting on the plate will cause a turning moment to urge the plate towards its closing position; upon termination of the gust the damper plate 13 will return to its original selected operative position. A rod 16 attached either to the sleeve 26 or to the damper plate 13 (see Fig. 3) is connected to a recirculated air damper 14 in such a manner that the total flow of fresh and recirculated air into the unit is maintained constant. The unit ventilator includes an air filter 9, a tempering heat exchanger 8 and a fan 4.

Title: Improved Appliance for Raising Sunken Ships.
Inventor: THOMSON THOMAS
IPC: B63C7/16
Filed: 1918-06-26
Abstract: 128,731. Thomson, T. June 26, 1918. Sunken ships, raising.-Relates to. the salving of sunken ships by means of lifting-ropes which are cross-traversed through the sea-bed beneath the sunken ship by means of an automatic boring- tool, as described in Specification 112,570, and consists of means for predetermining with precision the lines of cross-traverse of the ropes, comprising a setter for directing the boring tool and a guiding-weight, each adapted to be lowered and raised alternately from a floating barge, and guide each other to the desired place of deposit on the sea-bed. Figs. 3<x> and 7<x> represent in plan the positions of the setter B and the guiding- weight C within the well of the floating barge, Figs. 3<y> and 7<y>, represent the relative positions of the setter and weight during the operation of the apparatus, and Figs. 3<z> and 7<z> represent in end view the barge and the setter and weight resting on the sea-bed. The setter B is suspended from the barge by four ropes a<1> - - a<4>, one at each corner, and the weight C by two ropes c<1>, c<2>. The setter and the weight are coupled by a triangular contrivance D which is constrained in its rise and fall by a rope at each corner. one rope being a<1> or a<2>, another being c<1> or c<2>, and the third a guiding- rope d<1> or d<2>, the lower ends of which are secured to the setter. The distance between the centre line of the setter and that of the weight, when they are in lateral contact, is equal to one-half the distance between the lines E<1>, E<2> of two successive cross-traverses of the boring-tool, which is situated on the centre line of the setter. After a hole has been bored under the sunken ship along the line E<1> with the parts of the apparatus in the position shown in Fig. 3<z>, the setter is raised, the connector D removed and replaced, with the ropes a<1>, d<1>, c<2> in place of the ropes a<2>, d<2>, c<1> respectively, and the barge is moved by mooring-ropes so that the setter may be lowered again to the sea-bed in contact with the opposite side of the weight C, as shown in Fig. 7z, another hole then being bored along the line E<2>. The weight is then raised and the guide-ropes adjusted so that the weight may be lowered to contact with the opposite side of the setter, the setter then being raised and moved and re-lowered into contact with the opposite side of the weight, when another hole is bored. These operations are repeated for each fresh hole required.
