Abstract: 407,148. Pistons. LEWIS, E. C., 106, Marlborough Road, and KNIGHT, K. A., 17, Queens Road, both in Coventry. Nov. 26, 1932, No. 33480. Addition to 372,910. [Class 122 (i).] In pistons constructed in accordance with the parent Specification, relative movement between the piston and the connecting- rod is limited to a direction parallel to the engine crank-shaft by slotting the ball d in that direction to receive the correspondingly shaped head a of the connecting-rod. In the case of a solid ball the slot is extended to its periphery, the ball may also be made in two pieces which when assembled abut on the axis of the connecting- rod. The socket may be constructed in two parts which abut either at right angles to or on the axis of the piston. As shown in the Figure, the lower half of the socket screws in a member b<1> depending from the lower part of the cylinder head the upper half being pressed against shoulders on the root of the member b<1>. An independent screw member may be employed to secure the socket sections together. The joint between the socket sections may be made oiltight by a flanged ring.

Abstract: 1,156,022. Table trim. M. GANTERTMERZ. 26 July, 1966, No. 33580/66. Heading A4U. [Also in Division B6] A table trimming comprises a frameforming holder 1 which includes a vertical band 1<SP>1</SP> to enclose a table-top and a horizontal band 1<SP>11</SP> to lie on the circumferential face of the table-top, said two bands being resiliently stretchable and being disposed at an angle to each other and hingedly connected at the apex of the angle which they enclose, and a flounce 7 detachably secured to the vertical band. The main purpose of the holder is to secure a tablecloth to the table-top. As described the two bands are made of "Helanca" elastic lace and the band 1<SP>1</SP> is smaller than the circumference of the table-top which it is intended to be mounted so that it is held in place by its elasticity. Attached to the band 1<SP>1</SP> is a ribbon 4 to which is secured at uniform intervals socket members 5<SP>1</SP> of push button fastenings 5 the corresponding stud members 5<SP>11</SP> being secured to the inside of a second ribbon 6 to which the flounce 7 is sewn.

Abstract: 1,076,762. Wells &c. ARMCO STEEL CORPORATION. Aug. 17, 1964 [Aug. 19, 1963], No. 33593/64. Heading E1F.  A well assembly having a device for remote installation comprises telescopic tubular members 1, 10, opposed recesses 11, 19 in the members, a latch 26 in one recess biassed to engage the other recess, an inclined cam surface 34 on the latch, and a member 37 movable on one of the members tb co-operate with the cam surface to retract the latch into its recess. Figure 1 shows the casing hanger 10 held in the member 1 of an underwater wellhead by latches 26 retractable by the axially slidable sleeve 37, the hanger supporting a seal 44 and a tubing hanger 46 fixed to the member I by latches 52. The hanger 10 is lowered into the member 1 on a tool 70 (Fig. 6) having latches 73 supporting the hanger. The tool 70 is freed from the hanger by a wire-line tool 90 which raises a member 83 on the tool 70 to retract the latches 73. When it is desired to remove the hanger 10 the tool 70 is lowered into the hanger with a plug 117 and fluid is supplied by ducts 122, 108 to move a piston 99 on the tool to move the sleeve 37 to retract the latches 26 to free the hanger 10. The plug is removed by a wire line tool 129, the latches 73 are retracted by the tool 90, and the tool 70 is removed. The tool 70 is also used for operations on the tubing hanger. In Fig. 9 a packer 141 has its seal 144 engaged with the casing 15 by compressing the packer in the member 1 by means of a tool 140, the packer being held in the compressed condition by latches 148 engaging the recess 11. To remove the packer from the well, latches 168 on the tool are freed and engaged with an internal shoulder 181 on the packer, and the latches 148 are retracted by actuating a piston 158 on the tool. In modifications (Figs. 11, 12 not shown) flanged heads are sleeved on or in tubular well members, the latch release sleeves being actuated hydraulically.

Slow valve operation is effected by the handwheel 10 and rapid operation by turning the shaft 15 through 90 degrees to suddenly reduce the distance between the shaft 9 and stem 12. The shaft 15 is so shaped that rapid valve operation also results from axial motion thereof which may be obtained by a piston translated by electric, pneumatic, hydraulic or explosive means. The valve may be closed by either operating mechanism after it has been opened.

A lifeboat is constructed of reinforced synthetic resinous material comprising a moulded hull having buoyant bodies, e.g., buoyancy tanks 14 integrated therewith in the course of the moulding operation. The material used consists of a suitable resin and filling, e.g., a polyester resin with a glass fibre filling. The shell is formed in a female mould by applying resin which after gelling is covered by a layer of glass scrim cloth 10 impregnated with resin. The hull after the initial set is built up by layers 11, 12 and 13 each formed of a screed of glass or other reinforcing fibres impregnated with resin. The sides top and web ends of the buoyancy tanks are formed over a pattern from a first layer 23 of resin impregnated glass scrim cloth and two succeeding layers 24 and 25 of glass or other reinforcing fibres impregnated with resin, the top and face having wood core stiffeners 19-20 overlaid with layers 21 and 22 bonding same into position. Each top surface is provided with a recess to accommodate the end of a thwart. The tank components thus formed are placed in position in the hull in end to end abutting relationship along each side, the hull forming the closure to each tank. A layer 58 is applied to bond the tanks into position. Provision tanks and thwarts are similarly moulded and bonded into position in the hull. The deck and bulkhead sections 46 are formed over a pattern, similarly moulded as the buoyancy tank components, raised stiffeners 48 and 49 being provided in deck 47. A wooden keel is inserted in the keel section and layers 55 and 56 applied. Layer 59 is applied over all and the integral hull is cured.

Abstract: 1,199,790. Multiplex pulse code signalling. SIEMENS A.G. 19 July, 1968 [21 July, 1967], No. 34444/68. Heading H4L. In a time division multiplex system of the type disclosed in Specification 1,199,789 providing means to transmit asynchronous binary coded signals occurring on a plurality of input channels at any bit speed below a predetermined bit speed on a common output channel termed a " transparent " channel, each input channel is provided with means to measure the time between a change in the binary coded signal occurring on that channel and the immediately following time slot, as defined by scanning pulses, allotted to that channel and to convert that time into an analogue signal which is transmitted in said time slot. As described, the analogue signal is in the form of an amplitude modulated pulse and the system enables the common encoder in a conventional P.C.M. system to be used to convert the signal into digital form. A binary coded telegraphy signal N1, Fig. 1, is scanned by pulses S which define the times Z1 to Z5, from the immediately preceding changes in the digital signal these times being converted to amplitude values A1 to A5. Fig. 2 shows an arrangement in which a plurality of telegraph signals of various speeds are combined to form one channel in a conventional 24-channel P.C.M. system having a distributer V4 and analogue-to-digital converter AD. Each time value is transmitted as a 7- bit signal with an additional bit for synchronization. Channels K1 to K6 supply data at a speed of 0À2 KBd, channel K7 at 2À4 KBd which is split into two channels at 1À2 KBd and channels K8 to K32 supply data at a speed of 50 Bd, and the previously described time values are converted at U into amplitude values V1. These channels are combined to form a 4À8 Kbd signal by distributors V1, V2, V3 operating at appropriate speeds and supplied to point 11 of distributer V4.
