Abstract: 872,083. Tables, brackets. ETABLISSEMENTS REUGE. Oct. 23, 1957 [Oct. 24, 1956; April 11, 1957], No. 33132/57. Classes 52(3) and 52(5). A trolley comprises a central frame 7 from which extend members 3, 4, which may be panels or panel supports, which fold upwardly against the frame, the supporting castors being carried by rods 10 which are slidably connected with members 3, 4 near the outer edges of the members and are pivoted at their upper ends to the frame so that folding the members 3, 4 causes the rods 10 to lie against the frame 7. A pair of upper table panels 1, 2 are linked to the lower members 3, 4 and are carried by hinges, the rods 10 being pivoted to the hinges at 15, 16 so that when the members 3, 4, and, consequently, the panels 1, 2, are folded the rods 10 are raised so that throughout the folding movement the castors lie in the same horizontal plane. When the members 3, 4 merely support pivoted table panels, the panels are pivoted at points spaced from the common pivot of members 3, 4 and pegs engage keyhole slots in members 3, 4 so that when both members and panels are folded they are locked in the upright position. Provision is made for supporting a tray or like article P from the upright 7 of the frame.

Abstract: 1,048,349. Forced flow steam boilers. BAB. COCK & WILCOX CO. Aug. 14, 1964 [Aug. 20, 1963], No. 33195/64. Heading F4A. In a forced flow once-through steam boiler the working fluid flows in parallel through panels of upright tubes, the panels being supplied from a distributer vessel, the flow to those panels which may be less highly heated than others being restricted by Venturi-shaped restrictors in their connections to the distributing vessel. In the form shown the boiler has an upright furnace chamber 10, fired by burners 68, combustion gases discharging through a lateral pass 22 locating superheaters 44A, 44B and downpass 24 containing a primary superheater 28 and a reheater. The furnace chamber is lined with upright generating tubes arranged in groups to form coplanar panels extending between inlet and outlet headers such as 95 and 93, the walls in the region of the burners being additionally cooled by tubes located between the panel tubes. The inlet headers 95 &c. are supplied with preheated water from a mixing vessel 107. To reduce the flow of water to those panels which do not receive as much heat due to their location as others, restrictors are inserted in the connecting pipes from the vessel to the inlet headers serving those panels. Each restrictor 200, Fig. 5 (not shown), is in the form of a Venturi having a conical conveying portion 201, a throat 202 and a conical diverging portion 203. Following the restrictors, variable orifice type valves may be inserted in the pipes to allow for flow adjustment required as a result of changes in conditions in the furnace.

Title: Fastener feeding apparatus

Filed: 1972-07-17
Abstract: 1379964 Feeding fasteners MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 17 July 1972 [20 July 1971 27 July 1971 29 July 1971] 33297/72 Headings B8A and B8S Fasteners, e.g. screws, in hopper 10 are scooped up by members 11d on rotary drum 11 and drop on to plate 30 and thence to a shoot formed by parallel rails 25 and 26. Screws which are incorrectly positioned, i.e. whose heads are not resting on the rails with the stem depending between the rails, are dislodged from the track by impeller 32 comprising a cylindrical member (34, Fig. 11, not shown) with equally spaced projections (34a) extending the length of the member and a paddle wheel 40 either side of the member (34) positioned so that the paddle wheels depend on either side of the shoot. Rails 25 and 26 are also contoured (Fig. 7, not shown) to facilitate correct orientation of the screws. Electrodes (25a, 25b, Fig. 7) on one of the rails cause a short-circuit with the other rail when fasteners occupy the entire space between the electrodes, to stop rotation of the drum 11 and thus prevent further supply of fasteners until the row of fasteners on the shoot leaves both electrodes free. At the bottom of the shoot is an escapement device, Fig. 16, comprising a reciprocating block 57 with a slot 57a across it, through which the fasteners are fed one by one to drop through a hole 55 into tubing 72 through which each fastener is driven by compressed air escaping from a chamber (53, Fig. 17, not shown) when plunger 51 is in retracted position. In this position, a fastener previously held by its head between blocks 64 and 65 drops into hole 55, and the first of the remaining row of fasteners falls into slot 57a at 62. As the plunger 51 is extended, the part 57c of block 57 separates the row of fasteners from the fastener in slot 57a, which fastener moves along the slot to be received by blocks 64 and 65 which grip it by its stem. The fastener in the hole 55 is fed through tubing 72 (Fig. 1) by escape of air to a poweroperated fastening tool, e.g. a screw-driver.

Abstract: 933,185. Centrifugal pumps. KLEIN SCHANZLIN & BECKER A.G. Oct. 2, 1959, No. 33463/59. Class 110 (1). In a multi-stage centrifugal pump the casing clamped between suction and pressure covers is subdivided, by the interposition of one or more sections formed as intermediate clamping pieces engaged by the tie bolts, into a number of axially and independently clamped groups of sections, the housing parts within each group of sections being differently dimensioned to withstand the maximum stage pressure in that group. In the pump shown, the casing comprises cylindrical sections 12 which take the axial thrusts, while outer rings 13 take the radial strains. The sections are divided into two groups A, B, clamped between a rigid intermediate clamping ring 5 and rigid end covers 1, 2 by means of tie bolts 4. A nut 7 is provided on each tie bolt 4 against the intermediate clamping ring 5 so that the clamping force exerted on the high pressure group B can be made greater than that exerted on the lower pressure group A, the diameter of the tie bolts 4 being correspondingly greater over the region of the group B. The use of a lower clamping force on group A than on group B permits the use of thinner walls for the casing sections 12 of group A, the rings 13 also being made thinner. The nuts 7 may be replaced by split rings engaging a groove in each tie bolt 4, the two halves of each ring being held together by a surrounding sleeve. As a further alternative, separate tie bolts may be used for each group.
