Title: Stapler
IPC: B25C5/02
Filed: 1976-07-27
Abstract: 1499973 Desk stapler WILHELM DAHLE BURO-UND ZEICHENGERATEFABRIK 27 July 1976 [31 July 1975] 31140/76 Heading B4C  A hand operable portable stapler comprises a base-plate 1 having an anvil 21 for bending staple prongs, a staple magazine 2, an actuating lever 3 carrying a staple driver 11, pivot pins 25, 44 received in recesses 27, 46 for interconnecting the base, magazine and lever, each pin and/or recess being elastically deformable to facilitate stapler assembly and longitudinal ribs 35 on base 1 which co-operate with surfaces 31 on box-like structure 29 depending from magazine 2 to guide its movement relative to base 1. Preferably ports 1, 2, 3 are of plastics and pins 25, 44 and recesses 27, 46 are integral therewith, recess 27 being defined by a downwardly extending gripping claw, the entrance slot 28 to the recess being narrower than the diameter of pin 25. The claw extends the length of pin 25 and its lateral surfaces are in flush contact with vertical inner surfaces 23 of holding jaws 26 of base 1. Pins 44, Fig. 5, and the ends 48 of the arms 45 descending from lever 3 are bevelled to facilitate the assembly of the actuating lever on the magazine.  Facing surfaces 18, Fig. 3, of ribs 35 have detent members 34 which co-operate with guides 33 on box 29 to limit the relative movement of magazine and base-plate when thin sheets are stapled by insertion between the magazine and base. The flexible plastics construction of the tool and the camming surfaces of members 34, 33 allows the operator to force guides 33 past detents 34 and so swing the baseplate away from the magazine 2 and actuating lever 3 to permit thick objects to be stapled. Spring 19, Fig. 1, urges lever 3 away from magazine 2 to the extent permitted by detents 49, Fig. 3 and latching projections 52. Spring 37 urges magazine 2 away from base 1. Magazine spring 5 urges pusher 7 against the rear of a strip of staples so as to maintain a staple in alignment with driver 11.

Abstract: In the continuous production of a neutral sodium sulphite solution of 5 to 50% concentration, a caustic solution (50% commercial NaOH) is injected through the central pipe 18 and sulphur dioxide through the outer plenium chamber 21 (see Fig. 3). <PICT:1027846/C1/1>ALSO:<PICT:1027846/C3/1> <PICT:1027846/C3/2> In the process of mixing a liquid with a second material which may be solid liquid or gaseous, the second material is injected as a plurality of streams into an elongated rapidly rotating zone of the liquid.  The liquid may be admitted by a tangential pipe into a cylindrical container to form a rotating column, and the second material injected by an axial pipe having a closed end and radially directed orifices, see Fig. 1 (not shown).  In another arrangement, Fig. 2, the container 8 may be surrounded by a planum chamber 10 to which the second material is supplied by a pipe 11 and from which it enters the container through orifices 12.  Both arrangements may be combined, Fig. 3.  Nozzles or pipe extensions may be used instead of simple orifices and in the arrangements of Figs. 2 and 3 may inclined at an angle of 400 degrees to 60 degrees from the radius to augment rotation of the body of liquid.  Polymerization.-The apparatus and process of Fig. 2 are applicable to a continuous emulsion polymerization process in which 10 to 40% of a butadiene-styrene mix, or of vinyl chloride, may be mixed with an aqueous medium containing a catalyst, soap or other additive. Alternatively, the catalyst, soap &c. may be added through the central chamber 18 of Fig. 3, the monomer being injected from the plenium chamber 21.  Starch.-The apparatus of Figs. 1 or 2 may be used further gelatinization of starch, the aqueous cold water starch slurry being introduced axially in Fig. 1 or through the plenium chamber of Fig. 2 into a rapidly rotating body of caustic soda solution of about 120 G/1 (equal to 3N-NaOH) at 230 DEG  F. to provide a starch solution of about 30 G/l. In the apparatus of Fig. 3 the starch may be injected axially and the materials simultaneously heated by the injection of steam through the plenum chamber; a digestion temperature of 240-270 DEG  F. for 10 minutes will produce a flocculating agent for the Bayer red hand process of superior flocculating and settling properties.

Abstract: 1395351 Lubricating GREASE APPLIANCE CO Ltd 22 June 1973 [5 July 1972] 31341/72 Heading F2A Apparatus for distributing oil intermittently under pressure comprises a plurality of units mounted on an oil supply pipe connected to a pump, each unit being adapted to supply a predetermined charge of oil at each operation of the pump. Each unit 1 is cylindrical and contains a floating valve in the form of a cup washer 2 with a projecting lip 2a and a head 4 to engage a bore 5 in a piston valve 6 reciprocating in the cylinder. The piston valve comprises a cylindrical member 6a provided with a sleeve 7 carrying a sealing ring 8 and spring-loaded with respect to a flange 11 carried by the cylindrical member. The unit is formed with a ring 12 so that it can be threaded on to the oil supply pipe. The pipe is formed wth annular grooves each having a hole communicating with the bore in the pipe to allow oil to pass to each unit. In operation, oil enters the unit on a pressure stroke of the pump, and passes the floating valve 2 to fill the space below the sealing ring 8 and compress the spring 10 (Fig. 2). When the pressure drops, the valve 2 closes, and the oil in the unit is forced down the bore 5 in the piston valve and into the space above the sealing ring (Fig. 3). On the next pressure stroke, the oil is delivered through the bore in the cap 1a. The cylinder unit and cap are injection mouldings of nylon.

The head 18 is moved by a piston and cylinder on yet a third axis and a transducer 24<SP>1</SP> measures this last displacement. Transducers of the coil and internal magnetic core type built into 28 and 38 to surround the rods 26, 40,) are energized and connected to means for detecting the change in coil impedance based on movement of the core, Fig.3 (not shown) but roller bearing and other mountings could be used instead of the simple rod and hole sliding arrangement shown. When used to check holes in frames, the probe 36 is first positioned in an aperture correctly located and the X, Y and Z transducers are set to read zero. The probe is then applied to the test hole and the differences along the three axes indicated in the required units. The advancement of the probe into the hole could be used to measure its diameter where the edge location of the hole in the Z direction is known. In Fig.5 a centrally shown frame is being checked by surrounding plates 11 each mounting probes.

Abstract: 1,199,563. Freeze-drying comestible liquids. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 10 July, 1967 [15 July, 1966], No. 31826/66. Heading A2B. [Also in Division F4] In a process of freeze-drying a comestible liquid, e.g. a coffee extract, a slurry of ice crystals is formed in the liquid, the slurry poured on to a tray or belt and frozen thereon and the frozen material is removed and disintegrated into a particulate material which is then freezedried. The ice crystals may be grown in the liquid by passage through a crystallizer or by slow cooling in a tray to form dendritic ice crystals. Preferably the particulate frozen material is screened and those particles less than 40 mesh are recycled into the liquid to seed the ice crystal formation. Apparatus for carrying out the process comprises a heat exchange device for cooling the liquid to form a slurry containing ice dispersed therein, a tray or belt arranged at the outlet of said device so as to receive the flurry therefrom, means to cool said tray to below the eutectic temperature of said slurry, thereby forming a frozen material, means to particulate the frozen material, and means for freeze drying the particulated frozen material. The heat exchange device comprises a through-flow, refrigerant cooled, tubular crystallizer with oscillating agitating blades within the tube. The slurry trays are cooled from below by placing on a housing through which a refrigerant is circulated. In an alternative embodiment, the liquid is slowly cooled in a metal tray or on a metal belt in a thin layer so that a slurry containing dendritic ice crystals is first formed and which slurry is then frozen on the tray or belt.
