Title: Tools for use in crimping the holding races of roller or ball bearings
IPC: B25B27/00
Filed: 1961-02-10
Abstract: 981,151. Making ball or roller bearings; bending cutters. AIR FRANCE. Feb. 10, 1961 [July 16, 1960], No. 5096/61. Headings B3A, B3E, B3V and B3W. A tool for use in crimping the cylindrical sleeve 3 for holding the outer race 2 of a roller or ball bearing in a housing 1 comprises an arbor 11 adapted for coaxial movement relative to the bearing and carrying two punches 18, 19 for effecting a first crimping pass, said punches being concentric with each other and each having its circular leading edge 21 castellated to present teeth 22, the teeth of the different punches being bevelled in opposite directions in such manner as to cut the adjacent edge of the cylindrical race in tongues and bend the tongues through approximately 45 degrees alternatively towards and away from the common axis. A second crimping pass is effected by a tool comprising an arbor carrying a flat-faced punch 27 provided with a peripheral rim 28 which restricts the bending of the tongues. The punch flattens the partly bent tongues against the bearing outer race and the housing to complete the assembly. The first criming pass may be effected simultaneously at both ends of the sleeve, Fig. 1, as also can the second crimping pass, Fig. 5. Alternatively, the holding sleeve 3 is held between a mandrel 23 and a guide ring 24 seated on a base 25, Fig. 2, during the first crimping pass. The sleeve thus prepared is stocked for future use or fitted in its bearing to await the second crimping pass. In another embodiment the punches 18 and 19 are arranged on one side of the bearing and the flat-faced punch on the other side, Fig. 4. Specification 973,571 is referred to.

Title: Improvements in carton-feeding apparatus
IPC: B31B5/78
Filed: 1948-02-21
Abstract: 635,044. Packeting-machines. ROSE, A. G., PAGE, J., and ROSE BROS. (GAINSBOROUGH), Ltd. Feb. 21, 1948, No. 5176. [Class 94 (i)] In carton-feeding and opening apparatus of the same general construction as that described in Specification 485,468, wherein collapsed cartons 11 are fed from a stack 12 by means of a series of transfer blades 14 adapted in turn to be inserted into a carton and carry it to an intermediate station whereat the blade is withdrawn, there is provided a pivoted spring-loaded stripper plate 31 arranged to swing into engagement with the carton at the intermediate station to prevent movement thereof when the blade is withdrawn, this plate being movable under the influence of its spring towards each blade as it approaches the intermediate station, to an extent determined by a stop member movable by a cam in timed relationship with the movement of the blades in such manner that the stripper plate is allowed to move while in contact with the carton at substantially the same rate as the blade during the stripping operation. As shown, the blades 14 are slidably mounted for vertical movement on a pair of spiders 16 secured to a shaft 17 rotatable intermittently by gearing from a Geneva mechanism, the blades being movable vertically in timed relationship with the rotation of the shaft by a pair of chains as described in Specification 485,468. Each carton is opened by fixed stops 22 and 23 and subsequently partially collapsed by a pivoted arm 24 prior to engagement with the surface of a feed roller 27 against which it is nipped after withdrawal of the blade, by a segmental feeding member 28 so as to be fed on to a chain conveyer 29 which carries it to a filling and sealing machine. The stripper plate 31 is mounted on an arm 32 pivoted on the shaft 17 and has a projecting ledge 33 arranged to engage the upper edge of the partially collapsed carton during the withdrawal of the blade. The plate is movable by a link 34 pivoted to an operating arm 36 freely mounted on a fixed stud 37 and coupled by a spring 42 to a stop member 41 forming an extension of a control arm 39 also freely mounted on the stud. This arm carries a roller 43 engaged bv a cam 44 operating in timed relationship with the movement of the blades, the contour of this cam being such that the stop member 41 is first moved to drag the arm 36 so as to cause the plate 31 to approach a moving blade, and subsequently to commence its return movement at a slower rate than that of the movement of the blade so that the carton on the blade moves gently into engagement with the plate. Thereafter, the stop member is caused to follow the movement of the arm 36 as it is moved against the action of the spring by the engagement of the plate with the moving carton. After the stripping operation is completed, the arm 36 is carried by the spring to move into engagement with the stop member which then carries it to its initial position. Specification 608,559 is referred to in the Provisional Specification.

Title: Hydrocracking catalyst
IPC: B01J27/00
Filed: 1961-02-13
Abstract: A process for preparing a hydrocracking catalyst is characterized in that a refractory solid support having cracking activity and consisting essentially of SiO2 and at least one oxide of the group Al2O3, MgO, ZrO2 and ThO2 is impregnated with a solution of at least one of the compounds of the metals of Group VIa and VIII of the Periodic Table, the impregnated support is heated in an oxidizing atmosphere between 700 DEG  and 760 DEG C. for 1-8 hours and the oxidized catalyst is thereafter reduced with hydrogen at an elevated temperature.  Specified metals, compounds of which are used for impregnation, are Cr, Mo, W, Fe, Co, Ni, Pd, Pt, Ru, Rh, Os and Ir. Specified supports are natural aluminium silicates and synthetic composites of SiO2-Al2O3, SiO2-ZrO2, SiO2-Al2O3-ZrO2, SiO2-MgO, SiO2-Al2O3-MgO, and SiO2-Al2O3-ThO2.  Preferably supports are so impregnated that the final catalyst contains 0,01-20% of Group VIa or VIII metal, e.g. a support consisting of 63% Al2O3 and 37% SiO2 is impregnated with either aqueous Ni(NO3)2 so as to impart 1-6% Ni to the final catalyst or an aqueous solution of a Pt or Pd salt so as to impart 0,01-10% of Pt or Pd to the final catalyst.  Synthetic supports may be made by separate, successive or coprecipitation techniques.  Pelleting of catalysts may be effected in the presence of stearic acid, rosin or graphite.  The catalyst may be used in fixed or fluidized beds.  Examples are given. Specification 917,470 is referred to.

Abstract: 590,228. Electric indicators. MASCHINENFABRIK OERLIKON. March 2, 1945, No. 5259. Convention date, March 9, 1944. [Class 40 (i)] An alarm relay has only one indicator which is normally held in a middle position but moves into a lower position when the relay operates. The indicator is then moved above the normal position by hand and remains there until the relay reverts to its original condition. When a coil 11 becomes de-energized an indicator 4 pivoted at 3 falls, and allows a fixed alarm signal 13 to appear in the window 5, and an audible alarm is operated by the closing of contacts 15, 16. Application of pressure to the knob 18 raises the indicator to a position in which its lower portion 20 is displayed in the window 5 and simultaneously the contacts 16, 21 are closed. When the coil 11 again becomes energized the indicator 4 and contact 16 return to their original positions. By axial displacement of a pin 10 into a recess 9 instead of 8 the alarm is operated when the coil becomes energized.
