Filed: 1970-07-21
Abstract: 1309937 Feeding by clamps NECCHI SpA 21 July 1970 [21 July 1969] 35239/70 Heading D1G Apparatus for attaching a patch pocket on to a shirt front or the like comprises a clamp 12 for folding and guiding the pocket as it is sewn and a contoured pattern 13 wherein an electromagnetically urged follower pin 22 follows the pattern and through a system of levers controls the movement of the clamp 12, the folding of the patch pocket being achieved by side and end folding blades 50, 51 which operate simulataneously upon movement of a single actuator and which, through a lost motion linkage drive a second series of blades 79 which complete the folding operation for one part of the pocket. In order to fold the pocket it is located in between plates 93, 119 of clamp 121 above a plate 24 which holds the garment which is to receive the pocket. The clamp is moved upwardly so that a blade 41 is brought level with the clamp 121 and the blades 118, 140 are adjacent the gap in clamp and the plates 50, 51, 79 are below the level of the clamp. A cylinder 103 is actuated to move the blade 108 inwardly and consequently move the blades 140, 126 inwardly so that part of the edges of the pocket are pressed between the blades 119, 120 of the clamp and the edges hang downwardly from the clamp. Immediately after this operation the actuator 59 is operated and moves the plates 50, 51, 79 inwardly to fold the edges which were hanging down into a position between the plates 120 and 24. The blade 79 has a lost motion drive provided by a slot so that it operates after the blades 50, 51 having moved into the folding position. When the pocket has been folded an electromagnet (not shown) urges the follower 22 against the template 13 and the follower operates as in Patent No. 1136730 to move the work clamp in accordance with shape of the template.

Title: Improvements in and relating to dovetailing machines
IPC: B27F1/12
Filed: 1934-12-13
Abstract: 434,070. Dovetailing - machines. DRAPAK, O., DRAPAK, A., and DRAPAK, J., R÷chlitz, near Reichenberg, Czecho Slovakia. Dec. 13, 1934, Nos. 35854 and 35855. Convention dates, Dec. 14, 1933 and April 18, 1934. [Class 145 (i)] The movements of a dovetailing - cutter are controlled by a pin moving around a template the profile of which corresponds to one notch between two dovetails, the required number of dovetails being cut by repeated traversals of the pin around the template. In a dovetailing- machine, Fig. 1, the rotary cutter 7 and its driving motor 8 are mounted in a frame 9 which can move longitudinally on bars 19 mounted in a transverse slide 21. A bar 4 provided with a handle 5 passes through a guide 6 on the machine frame and through the cutter frame 9 ; by means of a wire 11 actuated by a lever 10 on the handle 5, a lever 13, Fig. 4, mounted in the frame 9 is rotated against the action of a spring 14 to force the bar 4 against a toothed rack 15 mounted in the frame 9, which is thus clamped to the bar 4 to move therewith. A pin 3<1> carried by the bar 4 engages the edge of a template 1, Fig. 2, removably secured to the machine frame, and having a single notch 2<1> corresponding to the space between two dovetails. Transverse movement of the cutter frame 9 is effected by a two-armed lever pivoted on the bar 19, one arm of this lever being formed as a handle 18, the other arm being connected by a link with the machine frame. By means of the handles 5, 18 the pin 3<1> is caused to trace out the outline of the notch 2<1>, the frame 9 being clamped to the bar 4 so as to move forwardly therewith; the clamping device 13, 15 is then released so that the bar 4 can be moved back to its initial position while the frame 9 remains stationary. In this manner a number of dovetails are cut by repeated passages of the pin 31 around the profile of the single-notched template 1. Two boards 2, 3 are clamped together at right-angles by clamping beams moved by screws against spring pressure. A member 25 ensures the positioning of the vertical board 2 with its lower edge level with the lower face of the horizontal board 3 ; the member 25 is then retracted by linkwork actuated by a handle 32. The machine may be portable so as to be mounted on a bench ; the cutter may be driven by an electric motor, compressed air or by a flexible shaft.

Title: Improved method and apparatus for extracting heat from the hot exhaust gases of internal combustion engines
IPC: F01N5/00
Filed: 1958-11-10
Abstract: 867,891. Forced-flow, waste heat boilers; feedwater heating systems. B.P. TANKER CO. Ltd., and NORRIS, A. May 21, 1959 [Nov. 10, 1958], No. 36004/58. Class 123(2) In a waste-heat boiler for extracting, heat e.g. from the exhaust gases of large marine. diesel engines to produce high pressure steam circulation water from a boiler 11, which may be externally fixed, is discharged by a pump 12 for heat exchange with a boiler feed-water heater 14, where its temperature is reduced to a value just above the corrosion temperature of the exhaust gases before being circulated through the coils 23, 24 of a steam generator 17 over which the exhaust gases pass. Steam for superheating is passed from the steam space of the boiler 11 to a heat exchanger 20, and a pump 22 urges feed water through the heater 14 and into the boiler. The system, which is self-balancing can be controlled by bypass valves 16, 19 to automatically adjust the steam pressure which influences the rate of flow of circulation water by controlling a valve 15. The circulation water may also pass through the heating coil of a low pressure evaporator 13 having a by-pass valve 31 controlled by the steam pressure. Low-pressure steam can be obtained from the boiler, or its circulation system, by taking out high pressure steam through a flash evaporator pressure reducing device. A valve 18 is provided for by-passing the heat exchanger 17 when the main I.C. engines are inoperative. In a modification a feed-water heater is arranged on each side of the evaporator, the supply of low pressure steam being augmented by directing some of the high pressure steam through a pressure reducing valve. In a further modification, in which the circulation water flows in parallel through a feed-water heater and an evaporator and in which some of the feedwater, after having been heated in the feed-water heater, is passed to the evaporator, a valve, controlled by the steam pressure is arranged to by-pass some of the feed water directly to the boiler. In an alternative arrangement of the arrangement shown in Fig. 1 the heater 14 is located in the circuit before the pump 12.

The object of using the whole time cycle to transmit and receive a code over the line pair is to avoid attenuation caused by time slot division normally necessitated by two wire digital working and to allow the line pair to be of long length, e.g. 10 km. As shown speech samples are transmitted to and from each substation over a corresponding line pair Z. Delta modulation is employed. The one and zero bits are transmitted over this line pair as positive and negative potentials and are generated and detected by operational amplifiers L and 01, 02 respectively, the detector comprising a pair of amplifiers 01, 02 connected to distinguish the zero bit from no signal in order to avoid the need for a start code. The amplifiers are connected to effect conversion to and from four wire form. Intermediate stores S and E and switches KZS, KZe, KVe and KVs effect concentration and multiplexing on to the transmit pair VS and demultiplexing and distribution from the receive pair VE of the four wire path. The substations are provided with low grade clock pulse generators which are not synchronized with the exchange clock.
