Abstract: 1376555 Hank holder D DELERUE 25 May 1973 [29 May 1972 27 Oct 1972] 25259/73 Heading D1J A hank 18, Fig. 6, is placed upon a pair of parallel horizontal arms 1, 2 carried by a support 3. The support 3 and a connecting- rod 7 are then swung in unison about their respective pivotal axes 4, 6 to a setting, Fig. 7, in which the arms 1, 2 are vertically disposed. This causes spring means 9, 20 on the rod 7 to be compressed between a fixed abutment 8 on the rod 7 and a bracket 24 through which the rod 7 extends, the bracket 24 being part of a body 11 sliding on the support 3. The sliding body 11 carries the arm 2. The compressed spring means 9, 20 causes the arms 1, 2 to be biassed apart to hold the hank 18 under tension whilst it is unwound overend as at 17. In a modified construction Figs. 9, 10, 11 (not shown) the arm 1 is also slidable on the support 3 so that when the support 3 is vertical the lower arm 1 can fall under gravity to engage the hank 18. When the support 3 is swung to its horizontal setting a latch (14) carried by the slide means for the arm 1 engages with a fixed pin to lock the arm 1 against movement along the support 3. The support 3, rod 7 and pivotal axes 4, 6 are such that the spring means 9, 20 bias the assembly downwardly when the support 3 is horizontal.

Title: Improvements in wireless transmission and reception
IPC: H04B1/26
Filed: 1926-10-11
Abstract: 285,108. Robinson, J. Oct. 11, 1926. Thermionic electors and generators; modulating systems.-The reproduction of received signals is consequent on a change due to such signals in the relative frequency of an oscillator and an absorber comprising a piezo-electric device. The intensity of the signal mav vary the magnetization of an iron core K, Fig. 3, to change the frequency of the oscillator V2 or of the absorbing circuit. Fig. 2 shows a tuned circuit L2 C2 shunted by the anode circuit of a receiving valve and arranged to absorb current from the oscillator V2 in accordance with its effective resistance which is varied in accordance with the incoming signals. The absorbing circuit X comprises a piezo-electric device which may be included in a tuned circuit coupled to an amplifying and detecting valve V3 or may be connected across this input circuit. Alternatively the frequency of the oscillator or absorber may be varied by a telephone in the anode circuit of the receiver the diaphragm of which forms one plate of a condenser which is part of the capacity of the oscillator or absorber. Fig. 3 shows an arrangement in which the valve V1 oscillates and incoming signals modify the amplitude of the oscillations so that the frequency of the oscillator V2 is varied. The anode circuit of the valve V3 contains a tuned circuit L5 C5 coupled to an inductance L6 in the grid circuit of the receiving valve V, to remodulate the oscillations in. this valve. A strengthening of this coupling enables these oscillations to be broken up into trains of oscillations the incoming signal varying the frequency and amplitude of the trains of oscillations. The frequency change in the oscillator V2 is preferably in such a sense that the valve V3 absorbs less energy so that the effect is cumulative. The Provisional Specification describes the use of a tuned circuit without a piezo-electric device as the absorber and the substitution of a selective amplifier for the absorber.

Title: Improvements in and relating to means for measuring the flow of fluids
Filed: 1921-09-26
Abstract: 193,452. Roucka, E. Sept. 26, 1921. Modifying scale of readings, records, and integrations.-An apparatus applicable as a fluid flow meter comprises a two directional cam surface adapted to be moved in two different directions in accordance with the variable measurable quantities or factors, such as velocity, and pressure, and a contact member which bears continuously or intermittently on the cam surface so that the position thereof corresponds with the product of the two factors. In a modification for indicating or recording the product of more than two factors, such as, velocity, pressure, and temperature, the contact member carries a second cam surface on which bears a second contact member and so on. For ascertaining the weight of steam flowing through the conduit the pressure of the steam through a pipe 2 in communication with the conduit, acts on a piston 3 against the action of a spring 10 and effects the longitudinal displacement of the cam-surface 6 on which bears a spring controlled contact roller 13 mounted on a rod 15 which carries an indicating pointer 16 and a recording pen 19. The velocity of the steam in any known manner acts upon a flexible band 24 fixed to a roller 23 secured to a spindle 21 and through gearing 5, 20 causes a rotary movement of the cam surface to position the roller 13. By increasing the number of rotatable cam surfaces and contact members the position of the last contact member will correspond with the product of all the factors.

Filed: 1927-09-29
Abstract: 294,799. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen, and Berkel, C. F. M. van. Sept. 29, 1927. Cutting slices in succession.-A slicing-machine comprises, in combination, a slicing knife, a support for the substance to be sliced, means for feeding the support intermittently towards the knife, a motor, and means whereby the motor can rotate the knife and also move it to and fro to slice the material. As shown in Fig. 1, the shaft 12 carries a sprocket 17 connected by a chain 23 to sprockets 18, 19 within a housing 16 on a bracket which swings on the shaft 12. The knife 22 is mounted on the shaft 20, and the shaft 12 is driven through worm gearing from a motor secured to the stationary frame 11. The .sprocket 19 carries a crank pin 25 connected by a rod 24 to a pin 26 on the frame 11, the housing, which is thereby oscillated, having an arcuate slot 27 for passage of the pin 26. The knife 22 does not advance during the slicing stroke beyond the vertical plane of the side 10<b> of the slicereceiver 10<a>, thereby minimizing the risk of accidents. The slice feed is effected by a rod 33 operated by a pin 34 on the housing 16 and connected to the ratchet pawl lever 32, a ratchet shroud 35 adjustable by the rod 37 and lever 36 being provided. In a modification, the driving- motor is carried on the oscillating knife bracket and, being on the other side of the pivot, counterbalances the knife. In order to permit rotation of the knife without bodily oscillation, e.g. for grinding, the connecting rod 24 may be formed as in Fig. 3. The pin 26 is normally secured, by a screw 40, in the offset portion 39. The screw 40 may, however, be released, rotation of the wheel 19 then causing the rod 24 to reciprocate without moving the housing 16, the guiding groove 38 being slidable on the stationary pin 26. In a modification, Fig. 5, the housing 16 may be locked against oscillation, the crank pin 25 being on a disc 41 driven frictionally by the sprocket 19 which is held against the disc by the spring 42.
