Title: Means for Measuring a Dimension of an Object
Inventor: PERSSON ERIK
IPC: G01B11/02
Filed: 1967-08-11
Abstract: 1,191,867. Photo-electric measurement of dimensions. ALLM€NNA SVENSKA ELEKTRISKA A.B. Aug. 11, 1967 [Aug. 12, 1966], No.36970/67. Heading G1A. To measure the width of an object, which may be hot, a photo-cell scans the object by means of a rotating mirror or alternatively a rotating slotted drum having the photo-cell on its central axis of rotation, the axis of rotation of the mirror or drum both passing through the focal point and being normal or close to normal to the optical axis of a lens or mirror collecting radiation from the object, whereby the object may move towards or away from the collecting lens or mirror without effecting the measurement. In one arrangement Fig. 1 a photo-cell 11, has, by means of a rotating plane mirror 14, placed at the focal point of mirror 15, a field of view along path 16 which scans the object 17 but remains parallel to the optical axis of the system. In another arrangement Fig. 6 a photo-cell 24 is positioned on the axis of a drum 23 which has a slot 25. In there arrangements the lens 26 and mirror 15 may be inter-changed. The output of the photo-cell opens a gate to pass a train timing pulses to a counter for the time the photo-cell scans the object, the reading of the counter thereby indicating the width of the object.

Title: Method of and apparatus for evaporating in down-flow evaporators
Inventor: WIEGAND JOACHIM
IPC: B01D3/06
Filed: 1954-12-23
Abstract: <PICT:0796331/III/1> In carrying out evaporation of a liquid in a tubular evaporator of the down-flow type, the liquid is preheated to a higher temperature than that corresponding to the pressure at which the evaporation is carried out, and the preheated liquid is expanded, in an expansion chamber disposed between the preheater and the tubular evaporator, in a plurality of pressure stages whereby a small fraction of the liquid evaporates and the vapours entrain the residual liquid so that it is evenly distributed in a finely-divided state into the individual tubes of the evaporator. The method is advantageously used for the evaporation of milk, fruit juice and blood; and it may be applied in multiple-effect apparatus.  Milk is pumped to preheater 2 where it is heated to 75 DEG  C.; and passes from there, at a pressure of at least 0.4 atm. absolute, through throttle 19 into expansion chamber 3, which is disposed on the upper tube-plate 4 of downflow evaporator 5.  The temperature inside the tubes 11 of the evaporator is maintained at about 60 DEG  C. by steam supplied to the evaporator-shell through inlet 12.  The lower ends of the tubes discharge into liquid/vapour separator 6 which is nonnected to a condenser 8 and a steam-jet ejector 9, whereby the separator is maintained at a pressure of 0.2 atm. absolute.  Chamber 3 is divided into three compartments by partitions 13 and 14 which have four apertures and six apertures respectively.  Approximately 2 per cent of the preheated milk evaporates in chamber 3 in three stages, the absolute pressures in the three compartments being, respectively, 0.35, 0.30 and 0.23 atm. abs., the temperature falling to 63 DEG  C. The vapours formed in chamber 3 entrain the remaining liquid so that it enters tubes 11 in a finely-divided state.  The main evaporation takes place in these down-flow tubes; and the concentrated milk is withdrawn from the base of the separator 6 by a pump.

Title: Improvements in fusible elements for electric fuses
IPC: H01H85/08
Filed: 1929-12-13
Abstract: 344,892. Fusible cut-outs. COX, C. W., 15, Hargreaves Road, Sefton Park, Liverpool. Dec. 13, 1929, No. 38188. [Class 38 (i).] Comprises a fusible element formed of two wires or strips of copper &c. AA<1> held in coaxial relationship in a holder such as that described in Specification 337,386; their adjacent ends are separated by a narrow gap B which is bridged by a metal or alloy S of comparatively low melting- point, such as a solder, which makes an electrical conducting joint with the ends. When the current rises to 30-50 per cent in excess of full load this solder melts and breaks the circuit but when the current rises 100-150 per cent in excess of full load the whole of the element is fused. In a modified form there are two gaps bridged by solder so that a complete section falls out when the solder melts. If stranded wire is used the two sections may be united either by a single mass of solder or the strands may be separately united. Specifications 1647/83, 10530/84, [both in Class 38, Electricity, Regulating &c.], 261,067, 327,961, and 337,386, [all in Class 38 (i), Electric couplings &c.], are referred to.

Abstract: 1,061,903. Safety harness. IRVING AIR CHUTE OF GREAT BRITAIN Ltd. Oct. 28, 1963 [Oct. 10, 1962], No. 38409/62. Heading A3V. A device for arresting the movement of a belt 6 of a vehicle safety harness when it reaches a predetermined speed comprises a tube 2 and longitudinally movable therein a belt-supporting member 12 from which are suspended by springs 24 a pair of weights 20 pivoted together on pins 22 and carrying bosses 28. If the tube is mounted so that the weights do not hang vertically they may be weakly spring-biased together. During normal movements of the wearer of the harness the weights move with the member 12. When the belt is jerked so that the predetermined speed is reached the weights by their inertia lag behind the member 12 and chamfered faces 26 engage a wedge or cone 16 associated with a plate 18 bolted to an extension 14 of the member 12. The weights are forced outwardly and the bosses 28 engage in pairs of holes 8 in the tube wall. When the load on the belt is removed the plate 18 moves away from the weights which automatically move together, by their own weight or by the weak spring link referred to above, releasing the bosses 28 from the holes 8. In an alternative embodiment, Fig. 4, not shown, the spring 24 is replaced by a pair of leaf springs (25) located between the weights and the tube wall which urge the weights to grip the extension (14) of the member (12) during normal movement of the wearer of the harness. When the weights lag behind, locking means as described with reference to Fig. 2 are actuated. In a further embodiment, Fig. 6, not shown, a single weight is suspended from springs (32) and slidably mounted on the extension (14). Plungers (38) housed in bores (36) and secured to a leaf spring (44) are urged outwardly to engage in holes (8) when their chamfered ends (40) engage the wedge (16). When the load on the belt is removed the plungers (38) are retracted by the spring (44). In all embodiments the strap (6) passes over a roller (4) when it enters the tube. A greater length of belt can be accommodated in the tube by securing the end to the top of the tube before passing it through a slot 10 in the member 12. There may be a roller associated with the slot 10. The weights may be coated with a plastics material to reduce rattle. The tube may be replaced by a channel section member and the holes 8 may be replaced by inwardly pressed-out tongues behind which the locking bosses engage. The locking means may be arranged to yield at a predetermined excessive load to give a shock-absorbing action. For instance the tongues may be of such a length that they bend back out of the path of the bosses at the predetermined load. In the embodiment of Figs. 2 and 6 the strength of the tube wall between adjacent holes 8 is such that the bosses or plungers respectively can pull through from one hole to the next.
