Patent GB-1234643-A (GB)
IPC: H01H43/12
Filed: 1968-10-24
Abstract: 1,234,643. Time switches. CROUZET. 24 Oct., 1968 [27 Oct., 1967], No. 50454/68. Heading H1N. A programmer for washing-machines, for example, comprises a continuously driven cam 1 having a projection 1a to move a contact 2b into engagement with a fixed contact 3 once per revolution and a notch 1b masked by an adjacent flap 5 such that contact 2b engages a fixed contact 4 after a predetermined number of revolutions (e.g. four, as shown). The flap 5 is pivoted by its shank 5d in a fixed support (12, Figs. 2 and 3, not shown) and a pinion (11, Fig. 2, not shown), on shank 5d is in frictional engagement with the flap 5 and meshes with internal teeth (9c) of a main cam bank (9) coaxial with cam 1, the main cam bank (9) being stepped at variable intervals by selection of contact 3 or contact 4. A tooth 1c rotating with cam 1 moves flap 5 a small angular amount per revolution by successive engagement with teeth 5a, the flap being held in its successive steps by the friction with the pinion (11) restrained by the normally stationary cam bank (9). When flap 5 reaches the position shown dotted closure of contacts 2b and 4 causes cam bank (9) to be stepped and the pinion (11) is rotated to restore flap 5 against a stop 12e on the fixed support (12, not shown). The flap 5 may be provided with fracture lines (5c, Fig. 3, not shown) such that some portions (5b) may be broken away to reduce the extent of coverage of notch 1b and thus the number of revolutions of tooth 1c needed to allow operation of contacts 2b, 4. The friction between flap 5 and the pinion (11) is provided by resilient axial fingers on the shank 5d, but greater friction to ensure that the return movement of flap 5 can raise the finger 2a is provided by a modified coupling (Fig. 4, not shown).

Abstract: 1,256,927. Grinding; milling lathes. FARREL CORP. 7 March, 1969 [8 March, 1968], No. 12196/69. Headings B3D and B3T. A roll grinding machine comprises a bed 11, means 12, 12a rotatably supporting a roll R, a carriage 17 movable along the bed and carrying a grinding wheel head 26 having a power-operated spindle 77 arranged to receive a grinding wheel, and an assembly 82 including a second spindle 90 arranged to be mounted on the grinding head upon removal of the grinding wheel, a grooving cutter 101 on the second spindle, and means for driving the second spindle from the poweroperated spindle. As described, the machine has two grinding wheels 78 for grinding a rubbercovered calendering roll R which is supported on neck rests 12, 12a and is rotatably driven from a shaft 16 driven from a motor 14. Shaft 16 is connected by gearing and a clutch to a shaft 49 driving through gearing in a housing 56 a lead screw 30 engaging a nut 29 in the carriage 17 which is thereby moved along the bed 11. The lead screw is also connectable by a clutch to a second motor 65. The clutches are controlled by a circuit so that only one or the other is engaged at any one time so that either the motor 14 rotates both the roll and the lead screw, so that the movement of the carriage is synchronized to the rotation of the roll when the grooving cutter is mounted on the head, or the motor 14 rotates the roll and the motor 65 the lead screw whenthe roll is being ground. The grinding heads 26, 27 are adjustable to and from the roll and are mounted on pivots 28, movement of the carriage along the bed 11 causing pinions 128 engaging racks 129 to rotate and thereby rotate eccentric cams 121 to rock the grinding heads so as to crown the roll. The grinding wheel and cover 29 of the head 26 are removed and the assembly 82 bolted to the housing and a pulley 87 is mounted on the spindle 77 of the head. The assembly has a first housing 83 carrying a shaft 84 driven by a belt 88 from pulley 87 and drives through a belt 92 the spindle 90 which is in a second housing 89 and carries grooving cutters 101. The housing 89 is adjustable relative to the first housing about an axis perpendicular to the axis of the roll R to the helix angle of the grooves to be cut in the roll and is also adjustable longitudinally of the first housing.

Abstract: 1288112 Dental crowns ION CO 19 June 1970 [20 June 1969] 29815/70 Heading A5R A dental crown comprises a cup-shaped shell having a sidewall flaring outwardly from a restricted open end towards a closed end which has an occlusal surface resembling the occlusal surface of a natural tooth, the shell being deformable so as to be expanded by a tooth when the shell is forced on to said tooth. The crown may be a temporary and constructed from a chemically-inert material such as a non-corrosive metal or plastics material, a tin alloy of 99% tin and 1% silver being exemplified, or it may be used as a permanent fixture if gold or another suitable material is used. The occlusal surface 11 has a central groove 12, and cusps 15, the cusps having a relatively thick wall and the groove a relatively thin wall, in comparison with the remainder of the shell. The cervix 17 of the crown is dimensioned to be smaller than the cervical end of a typical human tooth, and is provided with a rounded inner edge 18 to facilitate easy placement of the crown on a tooth (21), Figure 8 (not shown). The cervix 17 is also contoured to correspond to the cemento-enamel junction of a typical human tooth. Due to the thin walled nature of the central groove 12, the groove may be made shallower by pressing an instrument (39), figure 20 (not shown), against the undersurface of the groove, or be made deeper by pressing an instrument (38), Figure 19 (not shown) against the base of the groove.

The detector can consist of a scintillation crystal 6 on which is directly mounted a photo-multiplier tube 7. The output of the photo-multiplier tube 7 is connected to a ratemeter (8), Fig. 1 (not shown), whose output in turn drives the pen of a chart recorder (9). The relative movement can consist of rotating the blade whilst the source is moved along the bore, the movement being continuous or in steps. In a practical embodiment, Fig. 3, the gauging apparatus has a turret 50 having a number of blade handling stations, for blades 51 having eight bores each. The blade 51 in Fig.3 is held by fixture 52 so that the source 54 and detector 55 can be moved by means of slide 56 mounted on pillar 57 along the axis 53 of a bore in the blade. The slide 56 may be activated electrically by motor 59, clutch 60, with a pinion (61), Fig. 4 (not shown), and a rack (62), or it may be activated manually by handwheel (63) engaging pinion (61). The source is mounted at the end of a flexible rod 64, Fig. 10, including a plurality of spring steel wires 81 connected to a fixed collar 79 and a movable collar 80 thereby ensuring that the source is maintained concentric within the bore. The description discloses safety arrangements to prevent the source being effective when the blades are not aligned or correctly positioned or when the source meets an obstruction within the blade.
