Title: Electric reflector lamp
IPC: B62J6/02
Filed: 1934-12-14
Abstract: 432,340. Vehicle &c. lamps. ELEKTROTECHNISCHE FABRIK SCHMIDT & CO., GES., Bodenbach - on - Elbe, Czecho Slovakia. Dec. 14, 1934, Nos. 35889 and 35890. Convention dates, Dec. 14, 1933 and Jan. 12, 1934. [Classes 39 (ii) and 75 (iv)] In a vehicle or like lamp a cylindrical member, which is slidable axially in an opening in the reflector, comprises two parts, one part carrying an electric lamp bulb and the other part carrying a dimming screen in front of said bulb. These two parts are so connected that the bulb and screen move together, and in some cases additional means are provided to permit of further movement of the screen with respect to the bulb. The cylindrical member may project rearwardly through an opening in the lamp casing, and the screen may act in association with a hood immovably carried by the reflector. The bulb may be fed from three batteries arranged circumferentially between the reflector and the lamp casing. In the form shown in Fig. 1, a cylindrical member 2, slidably mounted in a nipple 8 on a reflector 1, is formed at its front end to receive an electric lamp bulb 3 and carries a tubular member 10 which is connected by stays 9 to a dimming screen 7. The bottom pole 6 of the bulb 3 bears against a spring 5 connected to a contact plate 4 at the end of the member 2. In the form shown in Fig. 4, the screen 7 is carried by drawbars 11 guided in the member 2 and can be moved relative to the bulb 3 by means of a handle 12. In the form shown in Fig. 8, an intermediate plate 36 fixed behind the reflector 1 carries a central cup-shaped member 39 and also insulated lugs 28 to receive the batteries 37. The bulb 3 is carried by a tube 41 and bears against a spring 27 which coacts with an insulated contact 26 carried by the tube 41 and engaged by a conical contact 25 which is connected by a spring 24 to a switch 23. The tube 41 is slidably mounted in a tubular member 42 provided at one end with a loop 43 serving as an operating handle, and at the other end with stays 14 to carry a dimming screen 30. The latter co-operates with a fixed hood comprising a substantially semicylindrical portion 7 and a cap 7<1>. The member 42 is slidable within a guide tube 15 which is tightly fixed inside a central guide of the cup 39 by means of a flange 16, the tube 15 being formed with a lateral rib to engage a positioning groove in the guide. The tube 41 is provided with a nose 17 which extends through a slot 18 in the member 42 and through a slot 19 in the tube 15. By this means, a rearward pull on the loop 43 causes the bulb 3 and the screen 30 to move rearwardly to the limit imposed by the slot 19 on the nose 17. A further pull causes the screen 30 to move over the bulb 3 and to close completely the gap between the hood 7 and the reflector. The loop 43 extends through a central opening in the hinged cover 33 of the lamp casing, and a bow 29 or overlapping lugs on the cover prevent removal of the bulb holder when the cover is closed.

Abstract: 777,272. Packaging machines. ELDORADO ICE CREAM CO., Ltd. Dec. 12, 1955 [Dec, 13. 1954], No. 36061/54. Class 94(1). [Also in Group XXX] Ice lollies are conveyed to a machine for placing them in bags 31 by a conveyer comprising a pair of endless chains 14, 15, between which extend transverse rods 16 each carrying a plurality of pivotally mounted flaps 18 resting on support bars 19-22. Each flap is adapted to support the lower end of an ice lolly, a plurality of which are suspended by their sticks from an overhead trolley 24. The support bars 19-22 are terminated each at a different position along the length of the conveyer, adjacent respective delivery shoots 27-30 leading to the bagging machine. In operation, the trolley, which includes releasable gripper mechanism for the sticks of the ice lollies, is moved in synchronism with the conveyer with the lower ends of the depending ice lollies disposed half an inch above the flaps 18. At a predetermined position, a trip lever on the trolley is tripped, causing the gripper mechanism to release the sticks so that the lollies are received on the flaps 18, but with their sticks still guided by the trolley gripper mechanism. The trolley continues to move with the conveyer until all the support bars 19-22 have terminated. The corresponding flaps at each termination fall in turn into depending position, causing the lollies carried on them to fall in turn through the conveyer and into the respective shoots 27-30, at the bottom of each of which is disposed a bag 31, so that the lollies enter the bags with considerable downward velocity. The flaps may be of different form to that shown, for conveying other articles, or for other purposes. Thus instead of extending first downwardly and then forwardly from the rods 16, as shown, they may extend first tangentially forward from the rods 16, and then downwardly to engage the support bars. On the return run of the flaps, in which they are in depending position, the flaps are cleaned by being passed through a detergent tank, a rinsing tank, and an air blast or other drying device.

Title: Improvements in magnetic latches
IPC: E05C19/16
Filed: 1953-12-31
Abstract: 756,580. Magnetic latches. NYA MURBRUKSFABRIKENS I STOCKHOLM AKTIEBOLAG. Dec. 31, 1953 [Dec. 31, 1952; Jan. 26, 1953; Feb. 2, 1953], No. 36362/53: Class 44. A magnetic latch for doors and the like comprises a permanent magnet 11 with two projecting poles 9, 10 whose pole faces are coplanar, and a, flattened armature 12, which in the closed position of the door or the like, is attracted by the two poles of the magnet, the armature being pivotally mounted on a shaft extending substantially transversely tothe direction in which the door or the like closes and parallel to the plane of the magnet pole faces when the door or the like is closed, the pivotal axis of the armature being positioned considerably closer to one pole 10 of the magnet than to the other pole 9, so that in closing the door or the like the armature will swing into contact with the magnet pole 10 before the door or the like is completely closed, causing a decrease of the length of the total air-gap- and a consequent increase of the force of magnetic attraction. The armature can be pivoted at one end or intermediate its ends and can be of L shape with the pivotal axis in the short arm so that the long arm tends to hang nearer to the pole 9 of the magnet. The armature may touch both poles of the magnet or an air gap can be left between it and the pole 9. Either the armature, the magnet or both can be mounted in housings, the.housings.having elongated fixing holes so that the relative positions of the armature and magnet can be adjusted. When the armature is not mounted in a housing it can be pivoted on a screw secured to the door frame or in the case of double doors on a staple fixed to a shelf so that the armature is adjacent the magnet which is fixed to the second closed door. The outer edge of the magnet pole 10 can be rounded and the corresponding end of the armature curved to reduce friction. The aperture 7 in the armature, for the pivot shaft, can be of greater diameter than the shaft to minimize sliding of the armature on the pole 10.

Title: Radix converter
IPC: G06F7/50
Filed: 1965-08-18
Abstract: 1,076,559. Radix conversion. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 18, 1965 [Aug. 21, 1964; March 15, 1965], No. 35378/65. Heading G4A. In a radix converter for converting a first number expressed in an accumulative scheme of notation of one radix into a second number expressed in an accumulative scheme of notation of another radix, the contributions from each ordinal of the first number to the lowest ordinal of the second number are accumlated, the first number minus the accumulated contributions then being divided by the second radix, operations being repeated for successively higher ordinals of the second number. An accumulative scheme of notation is one in which each ordinal independently contributes in true or complement form to the value of the number. Referring to Fig. 1 (not shown), a clock-driven counter (43) scans the bit positions of a decimal word register (15) initially empty, and a binary word register (1) holding a binary word to be converted to binary-coded decimal, and controls an equivalent-generator (3), so that the contributions to the lowest decimal order of all the bits of the binary word (on the assumption that they are "1") are supplied in turn by the equivalent-generator (3) to a units accumulator (5) where they are added in if the corresponding binary word bits are "1". The contents of this accumulator which are in 1, 2, 4, 6, 8 form are decoded in gates to 1, 2, 4, 8 form, and passed to a delay register (9) and also subtracted from the contents of the binary word register (1) in a subtractor (19). The subtraction result is placed in the binary word register (1) from which it is then removed to the subtractor (19) now provided with delay feedback to accomplish division by 5. The result is passed to the binary word register (1), into which it is then recirculated via a one-bit delay (37) to divide by 2. The (binary-coded) decimal digit in the delay register (9) is inserted in the decimal word register (15) and can be printed out. The sequence is repeated to evaluate successive binary-coded-decimal output digits, terminating under control of a zero-balance-test on the binary word register (1). Complemented negative binary input words are recomplemented before use. It is mentioned that bed to binary conversion may precede calculation on numbers, the results being converted back to bed as above.
