Abstract: 1312158 Welding by fusion T C DEARMAN 10 Dec 1970 [11 Dec 1969] 58720/70 Heading B3R [Also in Division E2] Aligning apparatus for welding together two pipes 6, 45 comprises a carrier 3 adapted to seat on an end of one of said pipes, 6, a chain 13 adjustably anchored on said carrier at two spaced positions to provide, with the carrier, a loop to tightly embrace said pipe end, and support members 22 carried by the chain and extending to one side of the loop to provide circumferentially spaced alignment supports for the other pipe, 45. The pipes may be of different size. The loop is formed to loosely embrace the end of the pipe 6 by drawing a free end of the chain around a carrier bar 16 and holding it fast thereon by a spring-engaged, handle-disengaged lever 17. The loop is tightened by operating a handle 11 which acts on the other end of the chain through a screw and nut 9, 10. The support members 22 are adjustable lengthwise of, and secured to, the chain, being provided with chain-receiving slots 25 and chain-engaging, spring-engaged, handledisengaged, toothed locking levers 26. The support members carry screw-adjusted fingers 35 engageable with the end of the pipe 45 for pipe alignment. The engagement of the fingers 35 may be made such as to allow relative pipe rotation for orientation purposes. The pipe 45 may be additionally supported by a chain 38 connected to a hook 36 of the carrier and, via a chain-length-adjusting screw and nut 39, 42, a clamp 41 engaged with the free end of the pipe 45. The carrier is provided with a carrying handle 44. In Fig. 7 (not shown), the aligning apparatus is used for the joining together of an elbow to a cylindrical pipe.

Abstract: 1292466 Punching; stamping INTERNATIONAL STANDARD ELECTRIC CORP 4 Dec 1969 [11 Dec 1968] 59274/69 Headings B3Q and B3W To enable material to be punched (or embossed) at at least two different locations 61, 62 which are close or actually break through into each other, a jig 66 is used which has as many different positions for retaining material as there are locations to be punched, the jig having an aperture associated with each position. The jig is correctly located relative to a punch by engaging a die in one of the jig apertures, material in the position associated with that aperture is punched, the material is moved to the other or another position and punched again. Similar pieces of material may be punched simultaneously using the different positions and then moved to other positions for a second and subsequent, if any, punching. Each location may consist of several points 62 spaced apart, the jig having an aperture for each point.

Title: Photographic apparatus
IPC: G03B17/52
Filed: 1971-12-23
Abstract: 1317520 Folding cameras POLAROID CORP 23 Dec 1971 [30 Dec 1970] 60172/71 Heading G2A A self-processing camera comprises a first housing section 18 which receives a film assemblage 27, a second housing section 12 containing the objective lens, and a third housing section 20 which includes the processing means (e. g. rollers 76, 78), the second and third sections being pivoted to the first in such a way that they can move in opposite directions so as to allow insertion and withdrawal of the film assemblage. The camera shown is of the folding reflex type in which a member (64), Fig. 1 (not shown) having a reflective surface on each side takes up one position for inspection and focusing, and another position for effecting the exposure. When the camera is in its unfolded position, Fig. 1 (not shown), the topmost of the film units in the assemblage (27) is spring-urged into the exposure position behind the exposure aperture (60). It is then pulled out between the pressure rollers (76), (78) which rupture the pod (52) of processing material and spread it between the sheets of the film unit. The section 20 containing the rollers 76, 78 is pivoted to the first housing section 18 by a pin 110. This is normally held in position by a latch 112. The latch is released by pressing a button 111 at one end of it, which enables the section 20 to be swung down, as in Fig. 3, so allowing insertion or removal of the film assemblage 27 freely. The assemblage has a tapered shape, owing the increased thickness at one end to the processing pods, and the receiving chamber 26 of housing section 18 is correspondingly tapered so that the assemblage 27 cannot be inserted the wrong way round. The housing section 12 which carries the objective lens is pivoted by a pin 13 to housing section 14, pivoted in turn by a pin 15 to housing section 16 which is itself pivoted by a pin 17 to housing section 18. When the camera is in the folded up position, housing sections 18 and 20 are in nested relation to each other Fig. 5 (not shown) and the front wall (100) of section 20 covers the release button and prevents actuation thereof. Section 12 is linked to section 20 by a hinge (19).  When the camera is unfolded, and a film assemblage 27 is to be inserted, section 20 is pivoted downwards about pin 110, and section 12 is pivoted upwards about the hinge (19).

Abstract: 764,192. Liquid filters. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 13, 1955 [May 24, 1954], No. 15179/54. Class 46. A self-clearing filter unit comprising a flat filtering element 1 disposed at an angle to the flow of liquid through a settling tank 6 subdivided by partitions 7a, 7b, 7c, extending across the tank transversely to the direction of flow of the liquid whereby sediment in said liquid is caused to impinge against the underside of the filtering element. The filter element 1 is supported between sheets 2 of perforated material supported between the flanges 3a and 4a of inner and outer frames, the inner frame being pivoted to the outer at 5 so that it may be swung clear of the element 1 to facilitate replacement of same. Unfiltered liquid enters the compartment 6b which may contain a magnetic type of separator 9, flows through apertures 8c and 8b into the next compartments and through that portion of the filter element disposed above the compartments and below the level of liquid, the filtered liquid then overflowing the partition 7a into the outlet compartment 6c and outlet 11. The filter unit has a width less than that of the tank so that channels are formed on each side of the unit. In the event of the sediment compartments becoming choked up, liquid flowing over the partition 7c escapes via said channels to the outlet end of the tank.

IPC: A61B18/14
Filed: 1979-10-26
Abstract: An electrolysis hair removal apparatus including a stylet adapted to be placed in contact with a papilla to effect destruction of same and further including an indicator 26 Fig. 3 for indicating the optimum position of the stylet 20 Figs. 1 & 12 and the duration that the stylet should remain in such optimum position during each electrolysis hair removable operation is provided The stylet is displaceably retractable in a probe which is, in turn, retractable into a housing for protection of the probe. At least one of the conductive leads 66, which provide power to the probe, is of a resilient material and is disposed for urging a slide 51 Fig. 12 within the probe toward a face thereof having an aperture, thereby facilitating movement of the slide by the operator of the apparatus for extruding and retracting the stylet 20. The stylet 20, VS, Fig. 3 is moved inside the pore (P Fig. 2) until a point of low resistance is sensed (as measured between a reference electrode 18, VR and the stylet 20). This activates a detector 24 to apply a detection signal SD to an astable oscillator 25 which causes an acoustic indicator 26 to produce an audible hum. A detection signal is also applied to a second astable oscillator 28 via a delay 27 are the frequency of the two oscillators is such that after a specified period the acoustic indicator 26 will cause the hum to be intermittent (that is, it will start to bleep). <IMAGE>

Title: Winding Control
IPC: B65H54/00
Filed: 1979-11-10
Abstract: In apparatus for winding or lapping ribbon, tape, yarn or the like, a guide path for the ribbon to a winding core (26) is defined by a first frame structure removably mounted on a table (12) and having a movable sleeve (62) defining a first loop in the ribbon path which is reduced in length with increase of tension in the ribbon to stop rotation of the core (26) and allow any snagging of the ribbon to be repaired. A further sleeve (62a) is movably arranged on the frame structure to take up slack in the ribbon due to inertia once rotation of the core (26) is stopped. The frame structure further provides a sensing roller (86) so spaced from a sleeve in the path of the ribbon as to allow passage of the single thickness of the ribbon, the roller (86) being deflected on passage, for example, of a lapped joint so as to operate a limit switch (90) and thereby stop rotation of the core (26) in time for the lapped joint to be attended to by the operator before winding. <IMAGE>
