Filed: 1971-08-27
Abstract: 1350614 Electromagnets PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Aug 1971 [31 Aug 1970] 40303/71 Heading H1P A remanent electromagnetic actuating device has a permanent magnet armature 20 made of finely divided permanent magnetic material bonded in a resilient synthetic material. The armature has a soft iron strip 11 arranged for rotation. The remanent core 3 surrounded by an energizing coil has pole pieces 4, 5 bridged by the permanent magnet armature. The central portion of the permanent magnet armature 20 is polarized across its width in the opposite direction to the end 22 which co-operates by way of a soft iron insert 23 with polepiece 5. In Fig. 1 (not shown) the armature co-operates with identical L-shaped polepieces. In Fig. 2 (not shown) the construction is similar to Fig. 3 except that the permanent magnet of the armature co-operates with an L-shaped polepiece whilst the soft iron strip co-operates with a straight polepiece. Fig. 4 (not shown) is similar to Fig. 2 except for the provision of a permanent magnet between the polepieces. In Fig. 5 (not shown) the armature co-operates with a pot-shaped electromagnet, bridging a central polepiece and a surrounding annular polepiece. The device may be used for moving a rubber thrust roller which in the armature attracted position presses a magnetic recording tape against a capstan.

Title: Electrical connector with spring pin contact
IPC: H01R13/02
Filed: 1964-10-05
Abstract: 1,026,939. Two-part couplings. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Oct. 5, 1964 [Oct. 7, 1963], No. 40409/64. Heading H2E. An electrical plug member comprises an insulating body having a pin contact member disposed in a bore, which pin has a rearward mounting portion supported in the bore, and a spring shank 38 and contacting portion 40 both of which lie within the bore with the contacting portion offset from the central axis of the bore. When the mating socket contact member 66 is inserted into the bore, the contacting portion 40 is deflected towards the central axis of the bore to provide lateral spring-biased engagement between the plug- and-socket members. The contacting portion 40 of the pin is of slightly smaller transverse dimension than the internal cylindrical wall of the forward contacting portion 70 of the socket for ease of slidable engagement. The forward contacting portion of the pin has a lead-in contour at its forward end and the bore also has a flare at its forward end for guiding the mating socket into the bore. The insulating bodies may have metal shells. The external cross-section of the body members may be rectangular, round or trapezoidal.

Abstract: 986,165. Releasable fastenings. UNIVERSAL MATCH CORPORATION. Nov. 1, 1962, No. 41334/62. Heading E2A. [Also in Divisions G2 and G4] A safe deposit box has an aperture through which a document may be inserted to fall into a receptacle therein, the box having a lock which can be opened by a suitable key; all the keys are separately identifiable by indicia either on the key itself or operated thereby, and a recording means such as a camera is actuated by the key to provide a correlated image of said indicia and said document. In the form shown, as the documents are inserted into the deposit box, they fall into a receptacle 22, access to which is gained by unlocking a hinged side panel 13. As the key 18 is turned in the lock 14 to open the box, it closes an electrical contact which operates a camera 15. The end of the key carries a small identification mark which is reflected by inclined mirrors 23, 24 into the camera. A calendar clock 27 is also reflected into the camera. Thus as the box is unlocked, a simultaneous photographic record is made of the identification mark on the key, the time and date, and the top document 21 in the receptacle 22. In the modification of Fig. 6, instead of the keys themselves carrying an identification symbol, the different keys are individually profiled to actuate various contacts energizing a display lamp A, B &c., which appears on the photographic record. In a further modification Fig. 7, a number of printing heads, as at 53, are provided, the particular head corresponding to the particular key unlocking the box being actuated to stamp an identification mark on the top document. A further identification means is illustrated in Figs. (not shown) 8-10.

Title: Comminuted meat products
IPC: A23L13/40
Filed: 1960-12-05
Abstract: In the production of comminuted meat products which contain sodium chloride, e.g. sausage meat mixes, the fat is emulsified by incorporation of calcium caseinate obtained by neutralization of milk casein with calcium hydroxide.  0.5-8 parts of the calcium caseinate, of pH 6.5-7.5, may be incorporated in 100 parts of the meat.  Tests which demonstrate the avoidance of "fat cap" in frankfurters filled with formulations of steer flanks and of beef chunks and pork back fat with ice, sodium chloride, curing salt of sodium chloride, sodium nitrate and sodium nitrite, a spice and oleoresin mixture and sodium ascorbate are described.  The calcium caseinate may be used in conjunction with other fat emulsifiers, e.g. sodium caseinate, milk solids, flours of wheat, maize and soya bean, gums and alginates.

Preferably the wall gradient is 0À0001-0À0003 radians and is not more than 80% of the punchangle. A punch for performing the method has a reduced shank 9 to receive the thick portion 2 which may not be subjected to the, or the last, wall ironing operation and is therefore less hard than the middle of the wall. A gap may occur between the punch and the container side-wall.

Title: Improvements in or relating to the teeming and degassing of molten metal
Inventor: FRANZEN ERWIN FERDINAND
IPC: C21C7/10
Filed: 1962-11-07
Abstract: <PICT:1029966/C6-C7/1> Molten metal is teemed into an intermediate receptacle located in a vacuum tank through a pouring arrangement such that the metal forms a divergent stream, the metal collecting as a deep pool the surface of which is exposed to the vacuum. The metal is tapped from the intermediate receptacle without the application of vacuum.  Degassing may be aided by the injection of an inert gas into the pool of metal in the intermediate vessel and also by the positioning in that vessel of a flow-interrupting member which collects the incoming stream as a shallow pool and allows it to overflow. In the apparatus shown in Fig. 1, ladle 10 is mounted on vacuum tank 30 within which is located tundish 60, the vessel 30 being made vacuum tight by O-ring seals 40, 43 and 52.  Molten metal is discharged from ladle 10 through nozzle 27 and refractory sleeve 97 in radiation shield 90, the nozzle and sleeve being so arranged that the metal falls in a divergent stream into tundish 60 from where, when a suitable depth of metal has been attained, it is tapped into a series of moulds.  Stopper rod 74 contains a tube 77 through which inert gas is passed to be discharged through porous disc 78. In the modification of Fig. 2 (not shown) the metal stream is collected in a shallow refractory tray attached to the top of tundish 61 and then overflows therefrom into the main body of metal.  This tray may have in its base a porous disc through which inert gas may be admitted; the tundish may also have a screw feeder 125 by means of which alloying additions may be made, preferably after degassing is complete.
