Title: Improvements in lace and the method of producing the same
IPC: D04C1/08
Filed: 1936-08-28
Abstract: 477,473. Lace. PRICE, W. H. Aug. 28, 1936, No. 23669. Convention date, Aug. 28, 1935. [Class 74 (i)] Fancy threads 10 outlining the design or otherwise disposed in a piece of lace produced on a braiding-machine are so tensioned and/or guided as to stand out from the ground. A kind of scalloped edge is thus obtainable. When a number of threads 10 are used they may themselves be braided together to form cords. The threads 10 always lie over one set of ground threads 11 and under the other set 12. To make the threads 10 stand out, their tension is preferably greater than the tension of set 12 and less than that of set 11. In crossing the threads of set 11, the threads 10 are always guided at the same side, preferably the inside, of the plate, or to the same side as the strongly tensioned threads. The lace is taken up by an open iron without a mandrel. According to the Specification as open to inspection under Sect 91, the fancy thread may be guided to the reverse side on certain sections of the lace, e.g. by using empty bobbins. This subject-matter does not appear in the Specification as accepted.

Title: System for adaptive control of the braking force in wheeled vehicles
IPC: B60T8/58
Filed: 1971-04-19
Abstract: 1348713 Antiskid braking systems SAAB-SCANIA AB 19 April 1971 [13 March 1970] 23751/71 Heading F2F  An antiskid braking system for vehicles has at least one brake force sensing device 3 at a wheel 1 generating signals representative of the braking force on the wheel, the signal being conducted into a detector 5 which emits control signals to a brake pressure regulating valve, comprising an hydraulic valve 8 and solenoid 29, in response to detection of maximum braking force for the wheel, the detector 5 comparing the received signals with reference signals with respect to reversal of phase and/or polarity of the variation of amplitudes. When a signal "1" is fed from detector 5 representing a braking force maximum the solenoid valve 29 opens the connection between a pump 44 and conduit 43 to feed oil to the underside of a piston 34, move the piston and cut-off the master cylinder 11 from the slave cylinder, at the same time expanding the available volume so that the brakes are released. When as a result thereof a wheel speed corresponding to maximum braking force is achieved the output from detector 5 is changed, the connection between pump 44 and conduit 43 is closed by a solenoid return spring and the cycle repeats so that the wheel is intermittently braked to oscillate about a speed corresponding to maximum braking force. In another embodiment the control system is equipped with a phase comparator and braking force pulsations are sensed by a force pick-up measuring the force operating between wheel axle and suspension, a displacement transmitter 50, or by an accelerometer sensing linear velocity changes. A pulse generator 47, Figs. 9, 10, is coupled into the system to bring about a pulsation of the braking torque on the disc 12 by means of an hydraulic piston mechanism 48 secured on the brake caliper 14. The reference signals are passed on to the phase comparator which also receives signals from the displacement transmitter 50 the output being either continuous or discrete and arranged to operate a valve to give continuous or step-wise control of the brakes. In a further modification the angular acceleration of the wheel is measured at each temporary release of the braking torque. It is stated variation in slip may also be produced by making the friction lining of the brake with sectionally different friction values. As shown in Fig. 11, a detector may be in the form of a valve 62 in which a slide 60 having fixed pistons 54, 61 is given longitudinal displacements de pending on the braking force applied to the wheel, the outer chambers of valve 62 being in communication with an oil container 26, the braking pressure being controlled by a valve 8 influenced by oil released through ports of valve 62.

Title: Waveguide junction
Inventor: WARE DAVID GEORGE
IPC: H01Q5/45
Filed: 1966-05-27
Abstract: 1,090,790. Waveguide junctions. STANDARD TELEPHONES & CABLES Ltd. May 27, 1966, No. 23912/66. Heading H1W. [Also in Division H4] A waveguide arrangement for transmission of up to four signals in multiplex comprises an inner circular waveguide 1 for transmission of two orthogonally polarized H 11  waves at frequencies within an upper band, and a surrounding coaxial waveguide 2 for transmission of two further orthogonally polarized H 11  waves at frequencies within a lower band. The signals are fed towards a horn 11, 12. The lower-band signals are fed to the coaxial guide through two rectangular waveguides 4, 5 arranged on orthogonal axes and coupled to the coaxial guide by tuned irises 6. In order to prevent backward propagation, pairs of conductive fins 7, 9 (one only of each pair visible) are arranged immediately behind the irises in planes parallel to the electric vector of the waves they are intended to reflect. Any energy propagated in the backward direction is absorbed by a termination 3. Upper-band signals are fed to the inner guide 1 by any known means. In order to isolate the two bands when the apparatus is used for reception, the diameter of the inner guide is such that only the upper frequency band will propagate in it. In addition, the coaxial guide is provided with a filter 13 to reject signals in the upper band. This consists of dielectric annuli spaced apart by a distance #/2 at the desired rejection frequency. The annuli also provide an impedance match between the waveguide and the horn. In order to correct irregularities in the polarization of the waves, each waveguide is provided with an annular clamp (Fig. 4, not shown) designed to produce a local deformation of the waveguide.

Abstract: 1,124,964. Endless conveyers. MARSHALL CONVEYERS Ltd. 2 Sept., 1966 [4 June, 1965], No. 23951/65. Heading B8A. An endless chain elevator having at each of a number of loading/unloading stations 31, 32, 33, a loading ram 39 for bringing a load 38 into the path of a carrier 40, means (Fig. 26, not shown) for controlling the operation of the ram 39 in a loading sequence, a loading sequence starter, an unloading ram 42 controlled by a destination selector (Fig. 24, not shown) and electrical means for inactivating each loading sequence starter when a loaded carrier 40 is approaching its station. Each carrier 40 is shaped so as to provide a U-shaped central recess (Fig. 11) to receive the unloading ram 42. Two narrow U-shaped recesses are provided on either side of the first recess to accommodate the ram 39 (Figs. 7 and 8, not shown) which has a correspondingly bifurcated form. In a modification (Fig. 21, not shown), the loading and unloading stations are disposed side-by-side instead of in line. The control of loading and unloading may be carried out by the use of reed-type limit switches operated by members fixed to the endless chains. Alternatively, control may be by means of an electronic shift register (Figs. 25, 26, not shown). The latter is controlled by pulses generated by a switch actuated by a sprocket driven by the endless chains. The pulses are serviced by a counter (not shown) which emits a different output for each pulse, thereby indicating the position of the chain relative to an arbitrary zero position.
