Title: Improved means for attaching touring bags, cases and the like to cycle saddles
IPC: B62J9/00
Filed: 1930-10-22
Abstract: 357,399. Luggage attachments. BROOKS & CO., Ltd., J. B. and HORDEN, H. R., Criterion Works, Gt. Charles Street, Birmingham. Oct. 22, 1930, No. 31688. [Class 136 (i).] Means for attaching a touring-bag, case, &c. to a cycle saddle comprises a bar &c. slidably mounted on the one part and adapted to engage loops or apertures carried by or formed in the other part. The rear edge of the saddle top 1 is fitted with a pair of depending loops 2, formed for example of straps passed through the usual slots. The rear wall of the touring-bag 3 is provided with two projecting eyes 4, and a coupling-bar 6 is passed through the eyes 4 and loops 2 and is held in place by turning a pivoted locking-rod 10 into the position shown in Fig. 4, a compression spring 8 at the other end of the bar 16 pressing the rod 10 against the adjacent eye 4. To detach the bag, the locking-rod 10 is turned into line with the bar 6 against the action of the spring 8, which is further compressed by the action of a camshaped part 10a of the rod 10 against the eye 4; when the parts 10, 6 are in line, the spring 8 draws part of the rod 10 into the eye 4, as shown in Fig. 5, and the coupling-bar 6 may then be withdrawn.

Title: Improved sealing element for use between relatively rotating members and method of making such element
Inventor: WILKINSON SAMUEL CLIFFORD WALT
IPC: F16J15/36
Filed: 1956-10-19
Abstract: 821,714. Stuffing-box substitutes. CRANE PACKING Ltd. Oct. 3, 1957 [Oct. 19, 1956], No. 31895/56. Class 122 (5). [Also in Group V] A method of making an axially-compressible sealing element for use between relatively rotatable parts 4, 7, Fig. 1, comprises moulding a tubular blank A, Fig. 2, of synthetic plastic or other suitable plastic material having a wear-resistant end surface 1 adjoining a portion of resilient material, and mechanically working the latter portion to form a bellows 2. The blank A may be, as shown in Fig. 2, produced by a moulding process in which a portion B of a mixture of polytetrafluoroethylene and a reinforcing material, such as glass, metal powder or porous carbon, is first inserted into the mould, followed by a portion C of pure polytetrafluoroethylene and finally by a further portion D of the former reinforced mixture. The sandwich material is then moulded and sintered and the blank is finally machined to form the bellows 2, the sealing surface 1A and a groove 3A. In the sealing application, as shown in Fig. 1, the finished element is clamped to the shaft 4 by a ring 5 engaging in the groove 3A and the sealing surface 1A is urged into contact with a seating ring 6 mounted in a stuffing box 7 by a spring 8 enclosed in a protective sheath 9. Alternatively, the sealing element may be stationary and make sealing contact with a member fixed to the shaft.

Title: Integrating method and apparatus
IPC: G01N30/86
Filed: 1958-10-08
Abstract: 869,477. Recording and integrating-apparatus. BECKMAN INSTRUMENTS Inc. Oct. 8, 1958 [Feb. 24, 1958], No. 32082/58. Class 106 (4). A pen 17 is moved over a record sheet 13 transversely by servo mechanism 14 in accordance with a variable voltage derived from a source 10 and the record sheet 13 is moved longitudinally at a speed proportional to the voltage by a motor 32 which also drives a generator 33 providing a negative feed-back signal to an amplifier 31 through which the variable voltage is fed to the motor, thus the longitudinal displacement of the pen 17 represents the integral with respect to time of the variable voltage. An attenuator 11 may be adjusted by an operator to maintain the peak values on the scale and another attenuator 11a may be provided to adjust the proportionality factor in the rate of feed, attenuation ratios of 1 : 5 : 20 being found satisfactory in the application to gas chromatography. A switch 46 closed when the pen 17 reaches the edge of the sheet 13 cuts out the paper feed should the operator fail to adjust the attenuator 11, thus saving paper but losing a section 48 of the record. The record sheet 57 is driven through a ball-and-dise variable speed gear in which the disc 61 is driven at constant speed and the ball arm 59 is set by the pen servo through a clutch 60. A double integration may be performed by using two such arrangements in tandem, Fig. 6 (not shown). A circular chart may be used with the base line preferably at the periphery.

Title: Improvements in excitation circuits for dynamo-electric machines
IPC: H02P7/00
Filed: 1955-11-10
Abstract: 816,733. Exciting dynamo-electric machines. IGRANIC ELECTRIC CO. Ltd. Nov. 10, 1955 [Nov. 26, 1954], No. 32181/55. Class 35. [Also in Group XXXVII] A dynamo-electric machine has its field windings f1, f2 connected as opposite arms of a bridge with a pair of resistors 13, 16, each forming one of the other arms, and diagonally opposed junctions of the bridge are respectively supplied from the output terminals 10, 18, and 14, 17, of magnetic amplifiers 11 and 15. The current-flow through the field windings is in one direction when the amplifier 11 has the greater output and reverses when that of the amplifier 15 preponderates. The amplifier 11 is provided with an input transformer 19 which has its secondary winding connected to the A.C. main windings 23, 28, of the amplifier through a rectifier network, the other amplifier being similarly constructed. The amplifiers also have D.C. bias windings 30, 31, and D.C. control windings 33, 34, the direction of field current being varied in accordance with the position of the double-throw switch 35. Signal control windings are added to the amplifiers if it is desired to vary the outputs in response to changes of load or other conditions. In order to improve efficiency, filter circuits, each comprising a series-connected capacitor and adjustable resistor, are connected across the output terminals 10, 18, and 14, 17, Fig. 2 (not shown). The filter circuits operate to provide output current which approaches pure direct-current in form, and hence causes less of the output current of the turned-on amplifier to be bypassed around the field windings through the rectifiers of the turnedoff amplifier. In another arrangement, the resistors 13, 16 are replaced by centre-tapped resistors, and a discharge resistance is connected between the tappings, Fig. 3 (not shown). A switch may then be included in the connections between each amplifier and the bridge circuit, so that, when an amplifier is turned on, the appropriate switches are closed and opened to isolate the inoperative amplifier, Fig. 5 (not shown). In a further modification, the centre tappings of the resistors are interconnected by two parallel circuits each of which comprises a switch and a series-connected halfwave rectifier, the rectifiers being oppositely poled. The switches are selectively closed in accordance with the amplifier which is operative at the time, and thereby ensures that more current will flow through the field windings, Fig. 4 (not shown). The resistors in the bridge circuit may be replaced by inductors which may have the same reactance and resistance values as the field windings. The units 11, 15, may be replaced by other forms of amplifiers.

Abstract: 1320619 Semi-conductor device SIEMENS AG 31 July 1971 [29 July 1970] 32689/71 Heading H1K The electrodes of a multi-electrode semiconductor device e.g. an integrated circuit are directly contacted by the ends of leads extending inwards from a lead frame. The frame is fabricated from a single sheet of metal e.g. brass or kovar (RTM) by etching in such a way that the electrode contacting tips of the leads are thinner than the remaining length of the leads and frame. In one embodiment a photolacquer mask corresponding to the form of the leads and frame is provided on a first face of the sheet and another mask covering the same area apart from the sites of the lead tips on the other. After etching to form recesses at the exposed areas the first face is completely covered with the lacquer and etching continued until the metal between the leads is removed. Alternatively the mask on the second face is amended to correspond exactly to that on the first and etching continued to completely remove the exposed metal. In both cases the semi-conductor body is then located with the aid of the recessed lead tips and these tips soldered or alloyed to its electrodes. After potting in synthetic resin the connecting parts of the lead frame are removed. Preferably the tips of the leads which should not be thicker than the lateral dimensions of the contacted electrodes are tapered.
