An induction crucible furnace, of the type comprising a rammed crucible 1 surrounded by an induction coil 2, includes a ceramic cylinder 3 with longitudinal drain holes or passages 5 which are open on the crucible side of the cylinder along at least part of their length, a water-tight and mechanically robust outer layer 6 and a layer 7 of thermally insulating and water-permeable material, e.g. asbestos, which prevents clogging of the water-draining passages 5 by the rammed crucible composition 1. The cylinder 3 is assembled from segment - shaped ceramic plates 4 with longitudinal passages 5 open throughout their length towards the crucible 1, (Fig. 3, not shown), or with longitudinal passages 5 open towards the crucible through slots (9) distributed uniformly along their length, (Fig. 4, not shown). Water issuing from the rammed composition drains freely via passages 5 and a furnace may thus be operated at full voltage with a new crucible immediately.

The shoes 28, 29 are held out of engagement by springs 33 and, in the freewheel condition of the device, are moved to engage body 25 on the driving of the shaft 10 when the cam member engages inner cam surfaces 35 of the shoes. The pins 20 are held in a cage member 21 having friction shoes 23 engaging a fixed race 15 through the action of a spring 24, this permitting cam member 37 to expand the shoes 28, 29 against body 25. For transmission of drive on both directions (i.e. also from hub 14 to shaft 10) a member 44 is rotated (Fig. 4) to cause a roller 47 to move in a slot 46 in the member 44 and so move across a slot 49 in a plate 50. A spring 48 interconnects roller 47 and a block 53 which is moved into a slot 34 cut out of shoe 28 to lock together the hub and the driving shaft, when the member 44 is rotated. The shaft 10 may be a stub axle shaft which is optionally driven on a four-wheel drive vehicle, and the hub 14 forms a part of a vehicle wheel mounting, the freewheel condition of the clutch device preventing the associated wheel from driving the engine (engine braking) but allowing the engine to drive the wheel, and the locked condition permitting engine braking of the associated wheel.

The piston chamber is in permanent communication with the inlet pipe and has a vent 29 controlled by a pilot valve 30 actuated by a float 84. As shown, the pipe is surrounded by a silencing tube 65 which has an outlet diffuser 74 below the low water level, and an atmospheric port 68 at the top, controlled by an elastic sleeve type antisyphon valve 69. The cylinder is formed in a removable top part 36 of the body, fixed to the lower part by a bayonet joint 33, and having a skirt 37 which shields the port 68. There is a connection 71 for discharging a quantity of water into the commode after the flushing action is completed and before the cistern has been refilled. The closure member 120 comprises a washer of rubber-like material recessed into the piston and held by a hollow stem 47. The seat co-operates with the outer edge of the washer, to prevent lift-out. The piston has a conical cup-shaped or seal 45, preferably of ethylene propylene. The base of this seal is retained by an inner peripheral edge in the stem 47. The wall in the region of this end is supported by the wall of a recess in the piston member 29. This prevents deformation of the seal under the fluid pressure and allows a less tight-fitting seal to be used. A loose wire 86 in the restricted opening of the hollow stem 47, helps to keep the opening clear of dirt.

This prevents the carrying-over of a stitch from a previously selected pattern. Needle bar jogging; feed by dogs. Needle bar 18 is carried in a gate 19 connected by a link 25 to a block 27 disposed in a guide slot 28 of an oscillating member 29 forming part of an electromagnetic actuator 30. The actuator comprises five solenoids 20-24 connected by a whippletree linkage 33 to member 29; the linkage is moved back and forth by a shaft 31, selective energisation of the solenoid selects the position of member 29. A similar actuator 43 is connected to the feed bar 35 by mechanism 46, 48, 49, 41, 39, 42. Disengaging needle drive. A block 102 secured to the needle bar 18 is selectively lockable to a second block 103 slidable on the needle bar and connected to the needle bar drive mechanism (not shown). The two blocks are locked together when finger 107 on clutch lever 105 pivoted at 106 to block 102 underlies block 103. A tang 108 on lever 105 is engageable by the first arm 109 of a bell crank 110 when the second arm 112 is engaged by a release member 113 movable by a solenoid 124, 125. A spring 116 raises the needle bar when needle reciprocation is interrupted. Control. A Hall generator (143, Fig. 2 not shown) is driven at arm shaft speed and provides a signal for 180 on and after top dead centre of needle crank movement and a further signal commencing one quarter of a revolution later. No output is thus provided during the last quarter of a revolution before top dead centre. These signals co-operate with a logic circuit (Fig. 4 not shown) including two AND gates (301, 302) two OR gates (401, 402) three 'one shot' devices (201-3) and three flip flops (601-3). The circuit operates to cause the skip stitch mechanism to operate when a pattern change is selected during the first 270 of crank rotation from top dead centre.

Abstract: 1327487 Hydraulic actuators C H BENNETT 27 Nov 1970 [19 Jan 1970] 56429/70 Headings F1D and F1F [Also in Division B7] An hydraulic actuator 20 comprises a piston 24 reciprocal in a cylinder 21 having heads 22, 23, the head 23 being attached to a support 12 through a strap member 33 integral with the head 23 and a support element 35, the strap member being made of a flexible, preferably plastics, material so that the orientation between the head 23 and element 35 may be varied. The actuator is single-acting and the piston rod 27 is hinged to a bracket 29 on a trim member 11 of a power boat (see Division B7). Fluid flow takes place through passages 39, 34 in the head 23, strap member 32 and support element 35, the fluid pressure acting on a diaphragm which in turn acts on the piston 24 against the force of spring 26. The fluid is supplied by a gerotor pump 40 which draws fluid from a reservoir 41, the outlet of the pump being connected by an orifice to a pressure relief valve 51 leading back to reservoir 41. Thus if excessive pressure occurs in the cylinder of actuator 20 and hence in the pump outlet, valve 51 opens to vent fluid to reservoir 41. An alternative relief valve construction is also described, Fig.8 (not shown).
