IPC: B65G47/24
Filed: 1927-08-15
Abstract: 288,471. Miller, R. E. Aug. 15, 1927. Discharging devices for endless - chain conveyers. - Bottles 4 are conveyed from a sterilizing or other machine by means of an endless conveyer with cups 3 in which the bottles are held inverted, and are discharged right side up on to chain members 31 of a second conveyer by means of guide box members 1 and lifter fingers 2. The members 1 and fingers 2 in a horizontal position are caused to travel for a. certain distance alongside the cups 3 during which time the fingers 2, which are slidably mounted, are projected to engage the necks of the bottles. Thereafter the members 1 and 2 are turned about a. horizontal axis 29, whereby the bottles are tilted and slide down the box members towards the chain elements 31 of the second conveyer. The bottles are received by a bar 30 which is caused to project upwardly between the elements 31 and hold the bottles clear from the elements until the box members 1 have been moved away from the discharged bottles. Thereafter the bar 30 is lowered allowing the bottles to rest on the conveyer. The reciprocating and pivotal movements of the box members 1, the sliding movement of the fingers 2 and the raising and lowering of the bar 30 are effected through the medium of lever mechanism acting in conjunction with cams on a driven shaft 6.

Title: Improvements in or relating to a process in the production of pulp by the digestion of cellulosic fibrous vegetable materials by circulation of lye through the materials
IPC: D21C7/14
Filed: 1950-09-04
Abstract: In the digestion of cellulosic fibrous materials by circulating through a digester containing the materials a lye consisting of an aqueous solution or a suspension containing a relatively small proportion of one or more chemical reagents (e.g. calcium hydroxide) which are sparingly soluble in water, a reservoir forming the lower part of the digester is charged with water or previously prepared lye and a fresh aqueous saturated solution or a suspension of the chemical reagent or reagents is then added, the level of the liquid in the reservoir not being allowed to rise sufficiently to contact the fibrous material.  Circulation of the lye through the fibrous mass is then started, the liquid being withdrawn from the reservoir at a point such that the withdrawn liquid is relatively free from suspended chemical reagent and being pumped up (optionally through a heater) into the digester above the top of the fibrous material and allowed to percolate down through the material by gravity and thus return to the reservoir, from which it is again pumped up.  During the circulation of the lye, fresh lye (optionally preheated) is continuously or intermittently bled into the reservoir, the level of the liquid in the reservoir not being allowed to rise substantially above the bottom of the mass of fibrous material so that the liquid, while in the reservoir, is maintained substantially out of contact with the material.  The proportion by weight of lye to cellulosic material may be 1 : 10 or less.  As shown, (in Fig. 1), an aqueous solution or suspension of a chemical reagent is supplied to a removable or hingedly attached reservoir b by means of a pipe e from a container (not shown). The liquid, before entering pipe e, passes through the shell k of a heater in which it is heated by means of a steam coil l.  A lye circulating pipe f leads from the reservoir <FORM:0720004/IV(a)/1> <FORM:0720004/IV(a)/2> b to a distributer ring g via a circulation pump (not shown).  The upper part of the digester consists of a chamber a holding the fibrous material and provided with toothed racks c holding an upper sieve member d which is provided with locking pawls and is pressed down on to the material (not shown).  In the upper part of the reservoir b is mounted a lower sieve member h.  As shown in Fig. 2, the reservoir b is charged by introducing water or lye through an inlet pipe i and leading it through a conduit j, which keeps the incoming liquid out of contact with the fibrous material and also carries the sieve members d and h.

Title: Machine-tool chuck
IPC: B23B31/175
Filed: 1969-04-29
Abstract: 1,216,151. Chucks. SOC. ANON. dite: CRIDAN. 29 April, 1969 [3 July, 1968], No. 21826/69. Heading B3B. A lathe-type chuck has jaw operating means comprising a floating annular member 15 formed with cam portions 14 adapted on longitudinal movement of the member 15 to operate the jaws 2 through levers 10, the floating member 15 providing for automatic adaptation of the jaws to any eccentricity of the workpiece surface. The chuck is also provided with locking and centring means in the form of studs 24 which are engageable with conical recesses 26 in the member 15 to lock the member 15 in a centralized position relative to the chuck axis whereby the jaws become adapted to close concentrically upon the workpiece. Movement of the member 15 to the left, as shown, is effected by pressurefluid jacks 20 and causes the stems 30 of the studs 24 to engage stop screws 32 so that opening of the jaws is normally accompanied by centring and locking of the member 15. Fluidpressure jacks 36, Fig. 4, are connected to an annular disc 35 which is engageable with the other ends 31 of studs 24 so that the annular member 15 may be released to its floating condition by remotely controlled operation of the jacks 36. During normal jaw-closing movement of the member 15 i.e. to the right, as shown, which is effected by jacks 20, jacks 36 remain extended till the studs 24 are displaced by the disc 35 and a microswitch 38 is then operated to actuate the jacks 36 so that final closing of the jaws is effected by all the jacks 20 and 36. Stop screws 32 may be permanently removed if the chuck is to be used continually with workpieces 9 requiring compensation for eccentricity.

Title: Improvements in or relating to a mechanism for automatically opening and closing gates, doors and the like
IPC: E05F13/02
Filed: 1936-08-08
Abstract: 481,285. Rising hinges. CRAWFORD, R. B. (Crawford, N. S.) Aug. 8, 1936, No. 21897. [Class 65 (ii)] A device for automatic operation of gates and the like is adapted to complete the opening movement after the gate has been opened approximately half-way by hand or by contact with a vehicle and then to close the door completely. In the form shown in Fig. 2, the gate is fixed to a member 7 which is pivotally and slidably mounted on an upstanding part 4 of a fixed base 2 and which carries a roller 15 running on a curved track 5 on the base so formed that the gate is lifted on opening in either direction. On each side of the lowest point of the track 5 is a member 11 resting on the track and mounted by means of a pin running in a slot in a fixed bracket 6 on the base 2. When the gate is pushed open, the roller 15 moves up the inclined surface of the member 11, which then tilts under the weight of the gate so that the roller runs down the further side of the member 11 on to the track 5 and continues up the track 5 for a short distance to complete the opening of' the gate. The member 11 is weighted to return to its original position, and when the roller 15 runs down the track 5 as the gate closes under its own weight the roller engages under the upper end of the member 11 and lifts it so that it can pass underneath, the pin of the member sliding up the slot of the bracket 6. The mechanism is enclosed in a cylindrical wall 17, fixed to the base 2, which forms a lubricant reservoir ; a hood fixed to the member 7 fits closely over the wall 17. In another form, Fig. 7, the gate member 31, slidable and rotatable on the pivot 24, is formed with a bracket 43 carrying a roller 49 running on a fixed track 27 of similar form to the track 5 of Fig. 2 and also has a sliding block 50 which carries a roller 54 running on a fixed track 26. The track 26 is formed with a hump 26<1> on each side of its central point, and is bounded by a wall 28 having gaps 29, 30 through which the roller 54 can pass; the fixed pivot 24 has a spring-pressed plunger 60 which normally forces the block 50 out to the position shown against the action of tension springs 69. As the gate opens, the plunger 60 is forced back by the hollow pivot member 31, but the block 50 is prevented from following it by the wall 28 engaging the roller 54; the roller 54 therefore moves up the hump 26<1> and runs down the other side of the hump to complete the opening of the gate. The roller 54 can now be retracted through the gap 30 by the springs 69, and the roller 49 runs down the track 27 while the gate is closing under its own weight, the roller 54 being inside the wall 28, and thus clear of the hump 26<1>, until the closed position is reached, when it is projected through the gap 29 by the plunger 60. The closing movement may be assisted by a spring, surrounding a spindle fixed to the top of the member 24, pressing on a thrust bearing on the top of the gate member 31.
